Encrypted drive disappears

Had an external working drive for Time Machine, previously unencrypted.
Encrypted it and then used it with TM for backups. Worked fine.
Filled up several times. Decided to go unencrypted since the backups were a lot slower.
Used Disk Utility, selected drive, with Erase when disk was encrypted. No issues. Normal erase.
Since then, the drive is no longer visible on any MBA when plugged into USB ports on either side, non-visible on desktop,
Time Machine can't see it. DIsk Utility can see the drive, says it is 300+gb external but can't repartition it.
The drive looks for all intents and purposes like erasing as encrypted did something beyond just erasing.
Does Disk Warrior fix this kind of thing? Is there a command-line tool I can use to save the expense of a Disk Warrior purchase?
Has anyone encountered the above before or heard of it?
Thanks!

Question 1: Why?
As a user.....just like you.....we cannot say "why", since only Apple knows the "why" about their design decisions.
Question 2: Is there any way to configure TC to support external encrypted drives throgh USB port?
No
Question 3: Does Time Capsule support encrypted drive through Ethernet LAN ports?
I do not know, since I do not have an encrypted hard drive connected to the Time Capsule with an Ethernet connection. Perhaps another user can test and answer for you.

Data Recovery from Partitioned and formatted Bit Locker Encrypted Drive

Recently because of some issues in windows 7 installation from windows 8 installed OS. it was giving as the disc is dynamic windows can not be installed on it. so at last after struggling hard no other solution i partitioned and formatted my whole
drive so all data gone included the drive which was encrypted by bit lockers.
For recovery i used many software such as ontrack easy recover, get data back, recovery my files professional edition but still i couldnt able to recover my data from that drive. then i found some suggestion Using CMD to decrypt my data first
http://technet.microsoft.com/en-us/library/ee523219(WS.10).aspx
where it shows it successfully decrypt my data at that moment my drives were in RAW format excluding on which windows is installed and then in CMD i check Chdsk which also shows no problem found. but now problem is still i coudnt able to recover
my data then i format the drive D and again tried to recover data using above software after decryption still no result.
Now i need assistance how i can recover my encrypted drive as it was partitioned and also formatted but decrypted also as i have its recovery key too. thanks

Hi ,
I am afraid that we cannot get the data back if the drive has been formatted even if use the
BitLocker Repair Tool.
You’d better contact your local data recovery center to try to get data back.

External Drive Disappeared!

My external drive is no longer recognized by my MacBook Pro. The drive is a SimpleTech, and I've used it for 3 years, on prior iMac and present MacBook Pro. Recently, I opened the external drive, and as I clicked on folders, the files in the folders would disappear. I restarted the external drive and computer, and everything was restored and could be opened. Ordered a new backup external, but before I hooked it up and transfered data from old external drive, the external drive disappeared from screen. Now can't get computer to recognize the old external. I can plug new external drive into computer, and it works fine, recognized, and Time Machine is backing up to new external drive. Unfortunately iPhoto library, and some other photos are still on the old external drive.

Armando,
If you have data you wish to retrieve from the old external drive, I would suggest getting a copy of DiskWarrior and using it to re-build the file system on the drive. This often fixes a drive that is not mounting or failing to transfer files due to directory corruption. Of course, if the drive has a hardware failure there is not much you can do to get to your data.

Can i recover lost data from encrypted drive by Bitlocker

Hello Dears. I had encrypted my drive by Bitlocker in windows 7.
few days after my friend did quick format in my encrypted drive.
my 300 gb of data lost. and nothing saved
i remember unlock password.
how can i recover my data ??? i need my data
i tried drive recovering tools (advanced EFS data recovery, easeus . . ,) . but . . . it's encrypted and formatted drive.
can i undo quick format and decrypt ???
sorry my english is not good.
someone help me please.

BitLocker is not the cause of failed to recover files.
Format a drive will clear all data saved on the hard disk. Thus recovery formatted data will be a hard disk based technology but not related to operation system. There is no build-in data recovery feature in Windows operations. So we will needto use third party recovery tool or contact third party data recovery company for current issue.
As recovery missing data service will be expensive, we can also check emails and contact friends to see if that can help get a part of files back especially for photos, documents etc.

Backing up an encrypted drive with Time Machine under Snow Leopard

In a nutshell, my question is “Can I back up an encrypted drive using Time Machine under Snow Leopard, and if so, how do I access its data from a previous day?”
I have a 1Tb USB drive connected to my MacBook, which runs Snow Leopard. The drive is formatted as Mac OS Extended (Journaled). This drive is included in the drives that Time Machine backs up. I used Disk Utility to create an encrypted drive on the USB drive (998Gb), also formatted as Mac OS Extended (Journaled). The encrypted drive is not on TimeMachine’s list of excluded files/drives.
When I go into Time Machine, I can see the USB drive and the encrypted drive in the side bar. I can access the files on the encrypted drive as long as I’m looking at how it stands now. But if I move backward in time, the encrypted drive is grayed out and inaccessible. If I click on the USB drive, I get a window that tells me it is 75.9Gb in size, and nothing else is available to me.
When I open the back-up drive in Finder and navigate to Backups.backupdb > macbook name > some date and time, I see my MacBook’s hard drive and the USB drive. The encrypted drive is not shown. When I click on the USB drive, I see an entry for drivename.sparsebundle. When I click on that I’m prompted for the password for the encrypted drive. When I enter it, I get a warning telling me that the disk image could not be opened and that the encrypted drive has no mountable file systems.
Is my encrypted drive really be backed-up and if so, how do I access the backed-up data?

Having received a bunch of views but no replies over the last 5 days, I decided to venture into my local Apple store and ask this same question. The response I got from the geniuses was that you can't get a reliable back-up of an encrypted drive using Time Machine under Snow Leopard. So, my only alternative is to copy the encrypted drive's contents elsewhere, unencrypt the drive, and then copy the contents back. This is what I expected, but not what I wanted to hear.

Internal Hard Drives Disappeared, Finder Memory Problem

Hello Helpful Folks,
I recently installed an addional internal Hard Drive, and an additional 1GB SDRAM. This worked great for a day, but the next morning, after powering up, system was extremely sluggish, and after much deadline-induced impatient problem solving, has gone from bad to worse (system refuses to acknowledge existence of internal Hard Drives). I apologize in advance for the length of this post, but as
the devil is in the details, I figure too much info is better than not enough.
Following is a breakdown of my system: AS IT LAST WORKED; RECENT UPGRADES; and MY LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE. Please don't interpret my all caps as shouting, just trying to organize this post for better clarity.
System is dedicated to Video Editing with FCP 3, running under OS 9.2.2. System is "off the Grid", i.e. no network, no internet, no printer, no gaming devices. System was purchased new in July 2001, by a friend. At one point I know this system had an Airport card, which was removed prior to my purchase in 2003. I can't remember what else it may have had installed in its history, but here's what it has now:
SYSTEM AS IT LAST WORKED:
**bold items are upgrades Original Owner or I installed with no apparent problems**
Power Mac G4 "Quicksilver" 2001
867 PowerPC G4, 256 L2, 2MB L3
-1 Stick "ValueRAM - KVR 133 x 64 C3/512" in PC 133 DIMM slot **
- "Virtual Memory" was turned off years ago due to conflict with FCP 3
-2 empty DIMM slots
-1 60 GB internal HD (Maxtor Ultra ATA/100), 1 partition, formatted HFS+, jumpered as "Master" on Internal ATA 2 ID=0 (which as I understand it is ATA/66 speed)
-1 Pioneer "Superdrive" DVD-R/W/CD-R/W on Internal ATA 0 ID=0
-NVIDIA GeForce2 MX with 32MB SDRAM in AGP Slot, feeding a 17" Apple Studio Display.
-PCI Display Card "formacGA7" - not attached to any external device, not sure what its intended purpose is.**
-3 Empty PCI Slots
-OEM Keyboard attached to Monitor's rear USB port.
-Microsoft 3 Button Wheel mouse with "IntelliEye" (wheel is 3rd Button) connected to Keyboard USB port (right side).**
-2 OEM FireWire (400) ports
-2 OEM USB (1) ports
Peripherals that have worked in various configurations with this system over the past 3 years:
-3 OWC Mercury Elite ("Oxford Chipset") Externally powered, External FireWire(400) 200GB Hard Drives, 1 partition each, formatted HFS+, daisy-chained to either of the FireWire ports.
-1 Canon GL1 MiniDV camera, attached either to the other FireWire port, or to the last drive in the chain, depending on my urgency/laziness factor. BTW, FCP 3 has worked flawlessly controlling this Cam for logging and Batch Capturing.
Applications on System Hard Drive that I have OEM CDs for:
-OS 9.2 - (I think I remember that OS X was removed from system due to conflicts shortly after original purchase)
-FCP 3
-DiskWarrior (version unknown, purchased from Alsoft in 2003)
-OWC Intech Hard Disk SpeedTools ver 3.5
Other CDs I have:
OEM CDs for Power Mac G4:
-Software Install, OS 9.2, CD vers 1
-Software Install, OS 10.0.4, CD vers 1
-Software Restore, OS 9.2 & 10.0.4 CDs vers 1, Discs 1-4 of 4.
-OEM Apple Hardware Test; Power Mac G4, SW vers 1.2.1
Applications on system Hard Drive that I don't have CDs for, that I rarely use, but I'd like to keep:
-After Effects 5.0
-QuickTime Player 6.0.2
-Toast Audio Extractor 1.1
-Toast Titanium 5.0.2
Applications on system Hard Drive I use if my wife is busy on our Windows XP machine:
-Photshop 6.0
-Microsoft Word & Excel
# of other Applications on System Hard Drive I either don't use or may be integral to the system: 260
# of Control Panels:
-Enabled: 34
-Disabled: 0
# of Extensions:
-Enabled: 174
-Disabled: 0
note: a number of the applications and extensions are for AOL, Quickbooks, Microsoft Money and the like, as well as other things I don't use (Airport, USB printers, Networking, etc.)
Smart things I did:
-Regularly made backup copies of my FCP projects to the external drives.
-Bought a copy of MacDrive so I can see what's on my External Drives on the XP machine.
-Printed out System Profile before I installed upgrades.
-Thoroughly searched this discussion board for and gathered as much info as I could before upgrading.
Dumb things I did:
-Made a copy, but not a clone, of my System Folder to one of the external drives when I first got it.
-Didn't keep any sort of separate log of what's on the External Drives.
-Never ran any sort of Disk Maintenance, even after one of the Externals crashed (DiskWarrior saved my butt on that).
-Ignored some of the advice on this discussion board.
Really dumb thing I did without even realizing it:
Captured all media for a rush job onto my internal system Hard Drive, as well as storing and using massive jpgs for the same job on that same drive...
Which led to painfully slow rendering times, and crashes caused by "Error: Out of Memory", which I interpreted as "Must buy more memory" and not "must make sure I'm not trying to edit media stored on system drive, especially with massive jpgs that I should reduce"
RECENT UPGRADES:
Here's what I did, and how I did it:
Turned off system, disconnected all External FireWire Devices, disconnected Monitor, opened case, touched various metal parts of case and power supply to discharge any Static, unplugged power cable.
-Installed 2 512MB sticks of "Lifetime" PC 133 SDRAM; total System RAM is now 1.5GB, all 3 DIMM slots now occupied.
-Installed 1 Maxtor "DiamondMax" Ultra ATA/133 100GB Hard Drive (8 MB buffer) as "Slave" (no jumper) in top of U-Carrier above System Hard Drive; attached to middle of original Apple ribbon cable, attached available power plug.
Taped spare jumper to inside of empty drive bay, noting origin and date. Did NOT push PMU button. Carefully closed case. Reconnected Monitor, did NOT reconnect any FireWire devices. Powered System on, but did NOT perform PRAM reset.
I don't remember the exact order of what happened next, but I think: System booted up normally, a window popped up saying a new drive had been found, would I like to intitialize it?, which I did as Mac OS extended, and then named. If I was instructed to restart, I did so, otherwise did not. Clicked on "about this Mac" and saw that it now showed 1.5GB RAM. I then went about moving Media/Render files off the System drive (and one of the Externals) onto the Internal Drive, with a combination of FCP's Media Manager, and dragging from the Finder. After files had copied, dragged Media/Render files from System Drive to Trash. Opened FCP project, had FCP re-link to new locations of missing files. Saved, closed, and re-opened project, set Capture/Scratch disc to new internal Drive. At some point I changed FCP's Memory Allocation from whatever it was to 512000KB Minimum, and 900000KB Prefered (and I hope I got all those zeroes right). Did NOT restart after changing Memory Allocation, unless a window popped up instructing me to do so, in which case I did. Re-opened my project, rendered a few thing at a noticeably increased speed, saved everything, emptied the Trash, shut everything down, and called it a night as it was 4:30 am.
A few hours later, I plugged the MiniDV and an External Drive into the FW ports and powered up the System. It was behaving extremely sluggishly. I would click on something, the pointer would turn into a wristwatch (sometimes with the minute-hand moving, sometimes not) and like an actual minute later, what I'd clicked on would open. All three drives were on the desktop, still had their files, and "About this Mac" still showed 1.5GB total Memory. So I powered down, disconnected the FW devices, waited a bit, and powered back up. Same sluggish response. I tried to open my FCP project file, and instead got a Window that said something to the effect of "The Application associated with this document could not be found". I think I tried to open FCP from the Applications folder on the System Drive and got the same message (I'd only had 3 hours sleep, no coffee, my client had died, and his family was coming for whatever I had in a few hours).
LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE
Panic had set in, which never solves anything, so I don't remember what order I performed which tasks, between searching for clues in this forum, and convincing myself that that would be faster than trying to compose a question, waiting for a response, etc.
The first two things I did, and I can't remember which I did first (both from Keyboard Commands during Restart):
Rebuild Desktop
PRAM Reset
Neither of those solved the problem, so I continued.
I tried restarting without extensions.
I would get errors that said something like "Not Enough Memory to Open Finder".
I tried booting from Disc 1 of the Software Restore Disk, which only wanted to destroy my data.
I tried booting from the OS 10 disk, with the same result.
I was finally able to boot from the OS 9.2 Software Install Disk, and actually saw both internal drives on the desktop, and the 1.5GB RAM in About this Mac. I tried to allocate more memory to Finder, but was informed that "Cannot Perform Requested Operation. This operation requires versions above 8.0".
I think at this point I decided that I must have too many extensions, and started disabling ones I thought irrelevent to my cause (mostly anything that said "AOL", "Airport", "Ethernet", "Printer", "Modem", "Speakable", and a couple things called "Open TPT".
It gets worse. Then I decided to turn off some "unnecessary" things via the control panels, but somehow managed to disable the control panels themselves: AppleTalk, DialAssist, File Sharing, Modem, Mouse (as I saw that Microsoft Mouse was among the others), Remote Access, Speech, USB Printer Sharing, and possibly TCP/IP.
That certainly didn't help anything (though upon restarting from the OS 9.2 Disc I was able to see the extensions and control panels in their respective "Disabled" folders in the System Folder). But I still wasn't able to get more Memory to Finder.
So, I decided a few more PRAM resets might help, which succeeded in making both Internal Hard Drives disappear. I tried booting up from the DiskWarrior disc, but even the Mighty DiskWarrior couldn't find the drives. I performed the longer, in depth version of the Apple Hardware Tools tests, which reported that everything's fine (including the new RAM), but made no mention of the Hard Drives at all. The deadline having long passed, I shut the system down. I read through more posts and tech articles, etc.
I searched my External drives with MacDrive on my XP, and found the drive that has the copy of my System Folder (which shows all extensions and control panels as enabled); not sure if the Quicksilver will boot from that, I don't know what the Keyboard command for booting from a FireWire drive is (if there is one) and the drive itself only has 900MB of free space.
I can't find any reference to Internal ATA drives anywhere in the MacDrive documentation; if it was possible I'd put them into the XP, get the files off the Mac drives, reformat them and install OS9 from the Discs.
This is where I am now:
The Quick Silver is still powered down. I removed the Microsft mouse and replaced it with the OEM Apple mouse. I opened the case, and removed the PRAM/Backup battery (manufacture date: July 2001). Couldn't find my voltmeter, so took the bat to Radio Shack and bought a new one. Had the Radio Shack guy test the old one: it showed 3.69 volts still. Have not installed the new battery yet. The case is still open, waiting for any advice any of you might have to offer.
Thank you all so much for your patience in perusing and pursuing this.
Sincerely,
Patterson
Power Mac G4 Quicksilver 867 Mac OS 9.2.x 17" Studio Display, 512MB RAM

Thank you Rodney and John,
The jumpers are correct for both Maxtor Drives.
Rodney, you are correct in that the initial problem (slow rendering/"out of Memory" crashes) was caused by my not realizing I'd stupidly captured several GBs of media to my system drive, and not checking which drives those files were on (as I'd assumed I'd put them on one of my external media drives) once that problem presented itself.
Before I'd determined what I'd done, I bought the extra RAM. After I'd found the media files on the System Drive, and saw that my dedicated media drives were too full to easily move them, I decided to buy an additional Internal drive so that I could:
-Move the Media onto it relatively quickly and finish my urgent project.
-Juggle all my media into a more organized fashion for archiving (as most of my projects are on-going long-term affairs)
-Wipe it, Partition it, and clone my System Drive onto it, as a spare bootable drive in case my OEM System Drive failed.
Copying the Media files onto the New Drive and moving the System Drive's Media files into the Trash worked great: huge improvement in Rendering, etc.
Before shutting down for the night I Emptied the Trash, and was pleased with the amount of space I'd freed up on the System Drive.
My guess is that the System Drive was terribly fragmented, having been subjected to intense use over the past 5 years without any sort of Drive Maintainence, and deleting that massive amount from it in one shot caused my extreme system sluggishness upon Startup the next day.
My subsequent lame attempts to solve the sluggishnes ultimately resulted in my losing access to both drives.
Today, I replaced the Backup Battery, pushed the PMU, re-attached the AC, and Powered Up with the case open as per your suggestion.
It was trying for a few minutes (the gray screen went black at one point, and then returned to gray) before presenting me with the flashing question mark.
There was, however, a quiet but distinct "buzzing" sound that would alternate: 1 sec "buzz", one second silence, one second "buzz", one second silence, etc. coming from the drives, even after the "?" appeared.
I powered down, removed the Ribbon and Power Cables from the new "Slave" drive, and powered up again, with the exact same results.
I powered down, removed the Ribbon and Power cables from the original "Master" drive, reinstalled the Jumper on the New Drive as "Master", plugged the End of the Ribbon and the Power cables into the New "Master" drive and powered up. The screen went to the "?" within 20 seconds instead of 4+ minutes, and no more "buzzing".
I put the Apple Hardware Tools Disk in, ran the "long" test, and everything came out fine.
I have to abandon this for now, but thanks again for your previous advice, and any more you may have!
Cheers,
Patterson

Encrypted drive will not accept password when re-mounting via Disk Utility

I have used the 'whole disk encryption' on one of my external HDDs. Sometimes i eject the drive when i don't need it because it's in a 4bay housing along with 3 other drives. I do this because OSX wakes up all my drives even for mundane tasks like safari browsing or even looking for a dictionary definition. But anyway, my problem is if i want to re-mount that encrypted drive from disk utility (left mouse click on greyed out drive and re-mount) it does not accept my password. I get the little shake like i typed it in incorrectly. Anyway, i tried it like a dozen times and received a dozen shakes of negativity.
If i swith off the drive unit and swith back on again the password is accepted just fine..
Can anyone else test this so i can mark it up as a Lion bug? Or is there something else i need to try?
Thanks

Can not shut down late 2011 MacBook Pro and turn it back on again without the hard drive disappearing?

Ok, I have searched for months for an answer to this question to no avail, probably because no one has experienced it before. I am hoping however that you guys can help me figure this one out cause it is driving me nuts! Also, I am not entirely sure what section of the support I should put this under so if I stick it in the wrong place, I apologize.
Right now my problem is very simple. When I turn off my laptop, and then try to turn it back on, my internal hard drive disappears... and I get the blinking folder with a question mark on it. I have figured out something interesting however. I have an install disk with Ubuntu Linux on it. If I boot into that first, then RESTART the laptop, not shut down and turn back on, it reads the internal hard drive just fine and I can boot as if there is nothing wrong.
Second part to the problem... If I allow the laptop in either OSX or Windows to go to sleep (aka shut off the hard drive but the computer remains on), when I attempt to wake it up, I am greeted with the usual log in screen of whichever OS I am in, but is frozen and after a few seconds goes black and restarts the computer to find that... Surprise! The hard drive is gone
I have tried every trick in the book that I can think of, but can not seem to come up with a solution to the problem... I know when the problem happened and if anyone thinks that that will help them figure this out I will type everything I did up till, including the crash that caused this, and my attempted fixes, but I have class right now so only if you guys want it I will type all that out.
What I am currently running is:
2011 MacBook Pro 13in screen
4Gb of Ram
1TB internal Hard Drive
OSX 10.11.whatever the newest update is... just updated the other day again.
Windows 8.1 on BootCamp 5 (yea I know its not supposed to work but it does) again, fully updated
Ubuntu 13.10 (I think? Doesn't really matter, its just an install disk I use to boot the computer)
If there is anything else that you guys need me to provide, I can, just simply ask. I can provide as much info as is necessary.

Sorry it took me so long to write back, But unfortunately this didn't help my issue.
My uncle and I did a lot of tests on this computer and have narrowed down the location of the problem a little bit.
We tried to first reset the SMC and the NVRAM as suggested, but the only thing that did was make the fans run on full tilt for the first session after restarting it for some reason. After that we tried re installing OSX over the OSX that was already on the system (not removing any of the files). This also didn't do anything but make refit stop working. Then we moved onto the next task at hand by removing the hard drive entirely and booting it as an external drive from one of the USB ports... as long as you booted it with the options key held down, it worked perfectly fine. Then we put an alternative hard drive into the computer and installed OSX on that. This time there was no trouble booting anything up. Everything seemed to work flawlessly. So we made a backup of my original drive (OSX, Windows, and all) onto an external hard drive and tested booting to it via USB. That again worked perfectly fine and booted right up with no problems. So after that we formatted the original hard drive and reinstated OSX. We then proceeded to transfer all the old files from the backup onto this new installation and LOW AND BEHOLD..... we were back to square one with it refusing to recognize the hard drive again.
So this basically told us that there appears to be something either wrong with the hard drive, or something got really screwed up in the software along the lines and by me copying all my old files back over, I just ended up bringing the screwed up file back over with it! (despite not copying over any settings of any kind) So I am still extremely confused as to what is going wrong... did some boot sector possibly get screwed up may be?

TS3299 opticals drive disappeared in my Windows 8 computer. After 1-1/2 on the phone this was corrected but now my Itunes don't recognize the drive. Error message stating registry errors. I tried running in windows 7 compatibility mode that don't

Purchased a new Ipad for my wife and integrated it with my windows 7 system and Itunes and made it through. Was able to sync and bring pictures, contacts and bookmarks over. Not to say it was easy because I never used any Apple product except my Ipad and Itunes. Really enjoyed using the Ipad and was thinking of getting a new Iphone this week being my contract is up.
Then the trouble began I bought a new windows 8 system after having trouble with my old hard drive. I have finances and Tax programs I use that I thought would be easier to continue using windows rather than trying integrating past years Quicken & Turbo Tax information into a new Apple system.
Well now I'm sorry I bought the new windows 8 system. First all my optical drives disappeared when installing itunes. After spending 1-1/2 on the phone with a service rep and finally was able to see my optical drive I thought everything was OK. Then more trouble. When I open Itunes I receive an error message that says my Itunes no longer recognizes my optical drive try reinstalling. I reinstalled 10 times and tried compatibility mode and the end result is my Itunes no longer could burn Cd's. I had this problem if I'm not mistaken in the past with ME system back many years ago. And did not want to go through this again but here I am disgusted once again.

I finally got my nano working (no thanks to Apple, hmpf!) and it's running fine with 1.0.2 now. For those with similiar problems try this:
+For Mac, you need to:+
+1. Downgrade to firmware 1.0.1 by deleting the files iPod_26.1.0.2.ipsw and iPod_26.1.0.2.ipsw.signature (are in the folder iPod software updates somewhere on the harddisk)+
+2. under Settings in iTunes you have to disable automatic download of updates, then restart iTunes.+
+3. Enter Disc Mode by holding menu & select for about ten seconds, then pressing play/pause & select for another ten seconds.+
+4. reconnect your nano to Reset, and when iTunes prompts to update, just don't allow it to look for updates and then reset with fw 1.0.1.+
I'm supriced Apple support didn't tell me about this? This worked great and is a very fast fix. I can't believe Apple got me to reinstall the whole OS, which didn't even solve it btw. USB 1, blah! Yeah right..

Encrypted drives accessible by other users

Howdy,
I am looking into encryption methods for OS X (previous post here: https://discussions.apple.com/message/22321009#22321009) and in playing around with it i found the following:
If i have an encrypted drive or partition mounted on my desktop i can not secure it by simply unmounting, logging out or starting a password protected screensaver. Another user can sign in through 1. fast user switching, 2. the main login window after i have logged out and 3. by using the 'Switch User' button at the bottom of the screensaver when it asks for a password. As soon as the other user logs in, there are my encrypted drives or partitions, no password asked!
The only way to secure an encrypted drive is to 1. Restart the Mac, 2. Turn off the Mac or 3. in the case of an external device, physically disconnect it.
Am i overreacting or is this a huge security concern/flaw and more importantly, are there ways to plug these holes if multiple users have to have an account on the same system?
I have read something similar a few months ago that mentioned simply unmounting a drive was not secure but it did not cover other users or offer a solution (can't find the article anymore).
Jay

This is how mounting volumes works in OS X. Once mounted, a drive is available systemwide, and not restricted to a specific user. The encryption that OS X sets up on a drive is per-volume only, and not intended to protect the data from other users on the system. Instead, its intent is to prevent someone from finding your drive and plugging it into another system to overcome security and access your files.
Ultimately the mode for securing files from other users of the same system is to not rely on encrypted volumes. If mounted, the unencrypted drive will remain unlocked and re-mountable. The only way to secure it again is to fully detach or eject it from the system.
However, overall it is not really a security flaw in the system. While intuitively it may seem the system ought to lock the drive again once ejected, this behavior still falls in line with how the system already handles local drives, where any volume (encrypted or not) is viewable accessible by other user accounts.
The way you can prevent another user from accessing the mounted volume is to get information on the volume, and then click the lock at the bottom to authenticate for changes, and then uncheck the box to ignore ownership on the volume. This will have the system observe permissions restrictions for files on the drive, but keep in mind this will only be restrictive to non-administrative accounts, as any admin can re-check the box and have full access to the drive again.
An alternative option is to use an encrypted disk image to secure files. Unlike encrypted drives, the system should fully eject an encrypted disk image when you eject it, requiring its password to be entered when mounting the image again.

Brand new iMacs & an external USB drive disappeared on one of them - help?

I'm new to this particular forum & I just bought a 2.8 GHz intel iMac (my wife is picking up for me this moment) - my boss just bought a 3.06 GHz intel iMac a few days ago, he installed Parallels & then Vista Ultimate w/SP1. He has an external USB hard drive & it showed up mounted on the desktop. When Vista asked him (voices from the dark side) if he wanted to link the drive to Vista he said yes - that's when the drive disappeared & he said that he couldn't get it back & he said that he couldn't find it with the explorer in Vista either. He tried rebooting, tried reconnecting the drive, doing this w/o launching Vista, etc - but he said that it wouldn't come back. He is not experienced with Macs, only the dark side so he's not familar with the system yet. I have not seen his Mac yet. I'm at work, so I do not have access to a Mac, I cannot offer troubleshooting tips for this cold turkey w/o a Mac in front of me, as it has been over 5 years since I've seen a problem like this.
That is why I'm writing this here, because I know that this is no doubt a simple fix for most of you. I can try to get him to come to this discussions site.
I can't wait to fly my new Mac today - should I just go ahead and re-format (low-level) & install from scratch? Even though I've purchased Parallels also, which needs no partition, should I make a partition anyway, incase i want to also use the Boot Camp route on the other partition?
Thanks 1.0E6,
Gino

Success - He finally did get it back after shutting everything down, powering down, pulling its connection, bring the mac back up sans Parallels/Vista, connect up the drive, drive showed back up, then startup Parallels/Vista.
btw - my new iMac is a dream (2.8/500/24") - I changed the memory to 4 mb, low level formatted the Mac, installed the software & "wow-zer" compared to my older lapstand iMac
btw2 - I had posted before to other forums (Airport, Mail), but this was the 1st time to this particular forum (intel iMac)

CD-RW drive disappears from entire system while using iTunes

I just installed a new CD-RW drive (master), removed all old CD burning software, and have installed the latest version of iTunes. I'm able to use the software without issues, Install CD's and Burn CD's, but after about 4-6 installs or burns my CD-RW drive disappears! iTunes will no longer recognize the drive and the drive no longer appears in My Computer or elsewhere.
I've tried physically reinstalling the drive and I've performed the steps in Microsoft Support Article ID 320553 repeatedly: http://support.microsoft.com/kb/320553
After following those steps and reinstalling iTunes each time, everything appears normal and I can use iTunes for about 4-6 burns/installs and then the same issue happens again.
Note, for what it's worth, I have an old CD-RW drive also installed, but as a slave that I do not use with iTunes or for anything else. It just exists.
Is this leaning toward an iTunes problem or a burner drive problem? I don't know where else to look.

b,
Well the issue happened again. Below is the DVD/CD Diagnostics. I then closed iTunes. I opened Device Manager and saw no ?'s or error messages. The D drive was missing again so this time I just tried the option "Scan for hardware changes" and it easily found the D drive and added it to the Device Manager. I then reopened iTunes and burned a CD with no problems. The plot thickens. Any clues?

Windows 8: Bit Locker encrypted drive "Access Denied" external drive

I rebuilt my computer and installed win 8.1 pro. Now my external drive comes up as an empty drive with "Access denied". Here is the kicker: I had turned off bitlocker on the external drive long ago as it interfered with automated backups.
Running the commands suggested here:
https://social.technet.microsoft.com/Forums/windows/en-US/738c1760-c96d-430f-9ae6-1f28f5c60998/windows-8-bit-locker-encrypted-drive-not-found-or-access-denied?forum=w8itprosecurity it shows the bitlocker but as unlocked. Drive still shows empty.
Any suggestions?
Thanks,
Markus

Ahh, turns out to be permission issue not bitlocker (or maybe bitlocker caused it to lose permissions, don't know).
Opened MyPc, right click on drive ->properties->security->advanced and selected apply to all.

Bitlocker, Windows 8 and self encrypting drives

I am trying to install a Seagate Constellation.2 self-encrypting drive with Windows 8 for use with Bitlocker. Articles that I've read imply that Bitlocker will recognise the SED.
There's no problem with the installation but there is no indication that Bitlocker sees it as anything other than a normal drive.
If I try to encrypt the full drive with Bitlocker, it's obvious, from the time it takes, that it is software encrypting it.
I have read the article about 'encrypted hard drives' and note that it says that SEDs are not the same thing. Frankly, I don't understand this and neither do other people on the web who have written saying that SEDs are now supported by Bitlocker.
Can you help with this please?
Thanks

The constellation ES.2 and ES.3 drives will not be able to be used as hardware encryption with Bitlocker on Windows Server 2012/8 they will just show as normal hard disks as your seeing and then you can use Bitlocker software encryption.
The reason they don't work is because Windows Server 2012/8 requires a OPAL 2 compliant drive and the Seagate constellation ES.2 and ES.3 drives are not OPAL 2 compliant drives. This is common across all vendors at the moment I was told, so until someone
releases a OPAL 2 compliant drive you will only be able to use bitlocker software encryption.

Time machine disk drive disappears

I just bought a Seagate 2 TB external hdd to use as my Time Machine Backup drive. Time Machine formatted it properly and named it Time Machine Backups. Unfortunately, it sometimes just disappears from the desktop, which I don't notice until I try to run Time Machine. It doesn't appear in Disk Utility either. I have it conntected to a USB port on the computer. Restarting the computer doesn't help, but if I unplug and then reconnect the drive, it appears again, or at least it has so far. Any idea why this drive disappears?

Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Boot into Recovery and launch Disk Utility. Is the drive recognized?
Reset the System Management Controller
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.
