Portable hard drive no longer requires password to decrypt it - security risk

I have a WD passport for Mac. It was previously encrypted and i would have to enter a password every time I wanted access to the drive - perfect. But then I had to decrypt it and when I had finished I re-encrypted the drive once again by right clicking and selecting encrypt drive. The drive is now encrypted again which is good, but the problem is that when I now plug it into my MBP the files are automatically accessible...the drive doesn't require a password to decrypt it anymore.
This is obviously a security risk so i want to go back to having to provide a password to unlock the drive. I've read some stuff about the password being saved in keychain but not had any luck looking for it and I'm a bit of a novice!
I'm using a 2012 MBP Retina with the latest OS
Can anyone help please?

Trying to restore my Mac OS after a hard drive failure and my password is no longer recognized, however I can log in by double clicking on the Lion Icon? How can I reset my password

I am trying to restore my Mac OS after a hard drive failure and my password is no longer recognized, however I can log in by double clicking on the Lion Icon? How can I reset my password

First, make sure caps lock is not on.
Another reason why your password might not be recognized is that the keyboard layout (input source) has been switched without your realizing it. At the login screen, you can cycle through the available layouts by pressing the key combinationcommand-space or command-option-space. See this support article.
If the user account is associated with an Apple ID, and you know the Apple ID password, then maybe the Apple ID can be used to reset your user account password.
Otherwise*, boot into Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. In the window that opens, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window opens. Close the Terminal window to get it out of the way.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
Select
 ▹ Restart
from the menu bar.
You should now be able to log in with the new password, but your Keychain will be reset (empty.) If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it.
*Note: If you've activated FileVault, this procedure doesn't apply. Follow instead these instructions.

I recently upgraded to Maverick 10.9.2 USB Hard Drive no longer shows

I just upgraded to Maverick 10.9.2 and my external hardrive (Toshiba Canvio Basic 3.0 Portable Hard Drive, PN#HDTB210XK3BA) is no longer appearing on my desk top when I plug it in. It shows in the Disk Utliity and I have tried doing a verify as well as a repair and I stilll get the same message...
"Updating boot support partitions for the volume as required."
I did a backup just prior to updating to Maverick so I know the external drive still works. Plus I am able to see the files on my PC when I plug it in to there.
I did try resetting the SMC and the NVRAM/PRAM.
I plugged other externa; drives in (Maxtor, Seagate, etc) and again they did not show on the desk top but did show in Disk Utlity.
I see this has happened to several folks but am wondering how they got it fixed.

You need the printer drivers for Mavericks.. have you loaded them?
You can expect issues as lots of printers are not yet up to date with Mavericks.. if you can find drivers. delete all the previous printers and start over using the new drivers.

I have a MacBook Pro, 10.10.2 Yosemite. My external hard drive no longer appears on my screen or in Time Machine

I have a MacBook Pro, 10.10.2 Yosemite. My external hard drive no longer appears on my screen or in Time Machine. I have gone into Disc Utility to repair disc, and get the message: Error: Partition map check failed because no slices were found. I was trying to follow Melophage's instructions by going into "Terminal" and entering "diskutil list; diskutil cs list; mount" and "diskutil info disk2." Then I entered the command "sudo got show disk1."   I am sure I have made the problem worse. Can you give me some help? Thank you. blelambert

How do I delete files from a portable hard drive

I've been backing up my MacBook Pro on an external portable hard drive. I need to delete some but not all the files from that portable hard drive permanently. When I highlight them and click to move them to Trash I get a message telling me this cannot be done because they are Read Only files? How do I go about it. I am required by work to delete them off this hard drive. Do I have to reformat the hard drive? If so how do I go about it?

You can easily delete files from a Time Machine Backup:
Click the Time Machine icon in the Dock.If the Time Machine icon isn’t in the Dock, look for Time Machine in the Applications folder.
Use the arrows or the timeline along the right side of your screen to browse through the backups Time Machine created.The windows behave just like Finder windows, so you can open folders, click items in the sidebar, and use the search field in the upper-right corner of the window.
When you find the item you want to delete, select it, and then open the Action menu (looks like a gear) and choose Delete All Backups for the item.

WD Portable Hard Drive Won't Mount

This is the second time I have had a portable hard drive that suddenly quits mounting on the mac. First, a Lacie, and now a WD. After working with apple support and trying everything I could never get the problem fixed with the Lacie. Luckly, when I plugged it into a dell PC it came up and I was able to recover all data.
I then purchased the new drive, the WD, and copied the information over. Today, the WD quit working. It will not mount on either of my Macs, IMAC G5 and a powerbook G4. It also unfortunately will not show up on a PC either. It is a combo, firewire/usb drive. It does show up in Disk Utility but will not let you select "mount" only "info" and "eject".
Long story short....anyone have any ideas. I read some posts about data recovery with "data rescue" and other products. If I can't get it to mount, can I still get the data off?
Help!!

If software won't do it - you'll try it all if it's important enough - there's the costly way; disk recovery specialists.
It's a cruel lesson, but I'm sure you'll have a better back up system / procedure in the future. Ideally save to two disks and keep a third set of (important) back ups off site.

HT6065 I updated my iMac computer to osx version 10.9.1 but now can't retrieve photo's from my lacie portable hard drive . Also when my computer comes on it does not show the finder bar unless I have another program up like Safari...should I delete my up

I have updated my iMac ot osx 10.9.1 but my screen no longer shows my finder bar unless I activate another program like mail or safari. also I can't access photos stored on my portable hard drive that was used before the update. Should I unsubscribe my update?

Did you make a backup of your system before you replaced the operating system?

Is it possible to run Adobe CC apps from a portable hard drive on multiple computers?

I work at a university that is not purchasing the Adobe CC license for it's labs. As far as I know Adobe will not create a deal that structures the fees in a way that makes it possible the University to buy into the CC platform.
This puts me a a tough spot as a person who teaches digital media in a University setting. Teaching legacy software (Adobe CS 5) puts our students at an immediate disadvantage.
To get around this issue, I have come up with the idea of having students purchase Adobe CC license short term (or longer if they like) as a textbook. However my lab administrators don't think there is a reasonable way to do this. Right now students would have to log into their User space on the University system, download software each time they came to class. This would not work for many reasons.
Is there a way to make Adobe CC portable, so students can download their own CC software and carry it around with them on a portable hard drive?
Would a system have to be installed on the portable drive or is there a way to run the software from a hard drive using the system on the computer it is attached to?
FYI the students and instructors have have no access to the computer systems, ex administrator or / root, level of the computers. Adding software and/or drivers can take months. Given time , I can get our IT folks to add a limited amount of structure to the system to make it possible for students to use Adobe CC from a portable hard drive if such a solution exists.
Thanks for your thoughts on this .
FYI the labs I need to MAC labs running OS 10.7.X (2.7 GHz Intel Core i5 - 4 GB RAM - 1 TB HDD) -

THe long answer is no.

iTunes: How to move [or copy] your music [library] to a new computer [or another drive] - http://support.apple.com/kb/HT4527 - a somewhat bewildering and not always easily understandable set of options.
Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the Option (alt) key (shift on Windows), then guide it to the iTunes Library.itl file in the moved iTunes folder.
For the record there's this reference for iTunes 11 but it really doesn't strike me as having the specifics you need. iTunes 11 for Mac: Move your library to another computer - http://support.apple.com/kb/PH12168
Windows users see tip at: https://discussions.apple.com/message/18879381
If you put it in the default location of Macintosh HD > Users > *User Name* > Music then you don't even need to start with the option key held down, iTunes will automatically look for it there. (Make sure there isn't anything already in the iTunes folder there that you want to keep since you will be replacing it with the one you are moving.)
Do not confuse (as you did) moving your whole folder and library with moving just media files as in

Trouble Transferring to a Portable Hard Drive and Backing up.

Hi there.
Recently I have come across a small snag when trying to back up my work folder to a portable hard drive. When I drag it across to the drive (Formatted FAT32 if that helps) it begins to transfer and creates the folder before giving me this message 'The Finder can’t complete the operation because some data in “Creative Work” can’t be read or written.
(Error code -36)'
So I decided to try and repair the permissions on Macintosh HD with Disk Utility. Which gave me this message repeatedly after several tries.
Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x .
Repaired "usr/share/derby".
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.
I also tried to repair my permissions with Onyx which game me the same message as Disk Utility. The strange thing about this problem is I cant seem to find anything wrong with any of the files it simply wont let me back them up...
I was able to burn two back ups of the folder with Toast Titanium. Although there seems to be some discrepancies with the file size on the burnt DVD and that on Macintosh HD. Being that the burnt folder is about 0.3 of a gig smaller. I have looked through all the folders and files and cant find anything missing. Though there is a lot in there and I may run into something down the line.
I would really like to be able to get past this problem without having to re-install OS X because I am still not sure whether I have a complete back up of my files on disk.
If anyone could offer me some suggestions I would be greatly appreciative.
Thank You.
(I hope my description wasn't too confusing)

Hi Piccolo32,
There's probably 1 or more files in the folder that are causing the issue. Depending on how many files your dealing with, you could consider dragging and dropping the files 1 by 1, to precisely track down the culprit(s).
*(error -36)* Please see the following posting and let us know if it's the exact same issue your having: http://discussions.apple.com/thread.jspa?threadID=1771300&tstart=3285
*(SUID Error)* Please see this much longer discussion posting, which offers various solutions: http://discussions.apple.com/thread.jspa?threadID=1204263
After reading threw the above posting, it appears, according to apple, the message your seeing can 'safely be ignored'. This is concerning the SUID file.
You appear to be having 2 issues. I was unable to find a solution for the error -36 issue. My suggestion about trying to narrow down which file(s) might be causing the issue is still worth trying, as long as you don't have 100s or 1000s of files to sift threw.
MacLovin
*Remember FAT32 has a file size limitation of 4GB (-1 byte). The previous posting is good advice, regarding formatting the drive to a native apple format.

I read the posts but confused on best way to move an entire library to a portable hard drive so it not only would be backup but also could be taken to family who also have Macs with ilife6. So they wouldn't have to manipulate individual jpegs, put in albums and retitle.
Many thanks,
Ralph

The item that stopped it had a long title and a /.
In OS X the slash '/' is a shorthand for New Folder (or Directory), so, for instance, Home/Pictures/iPhoto Library Folder reads to the Operating System as Home Folder -> In there Pictures Folder -> In there iPhoto Library Folder. If you use a / in a file name, the computer things in means new folder and that makes no sense, so the copying stops.
How long is the Filename? OS X can use very long names (tho' I can't recall the exact amount offhand). However Window formatted disks have a 32 character limit. I wonder if your external disk is formatted for Windows?

Can't get my portable hard drive to conect with FCP! What should I do?

Every time I try to reset my scratch disk to have my media go to my portable hard drive the message "Unable to set scratch disk. Selected directory is on a write protected or non-writable media." How do I change/fix this so my media can be sent to my portable hard drive?

Hi - Try this.
In the finder, click on the external drive icon.
Go to the Menu:: File > Get Info
A window will open.
At the bottom of that window, click on the triangle next to "Sharing and Permissions" to open the pane.
Click on the lock at the bottom corner of the pane and enter your password so that you can change the permissions for the drive.
Change the permissions. Re-lock the pane.
Close the window.
Restart your computer.
You should be good to go.
Hope this helos.

Canvio 1.0 TB USB 3.0 Portable Hard Drive HDTC610XK3B1 Sluggish

Bought a Toshiba Canvio 1.0 TB USB 3.0 Portable Hard Drive (HDTC610XK3B1) back during Black Friday 2011. Since I've had it, I've used it on my laptop, my rather powerful HP desktop, and another pretty powerful ACER desktop and all exhibit a very weird problem with the hard drive. Almost as if it's going to sleep or becoming idle, if I haven't accessed it or used it in some time (say I open an image that's on the drive and work on it for 5 minutes in photoshop) and go to either browse, save, or just about anything that would require access to the drive, things lock up for about 15-20 seconds and as I watch the hard drive (which the light will be off) the light will suddenly come on flickering which will then unfreeze the system and I have access to the drive.
It's the only potable hard drive I have that's doing this. I'd imagine it's some sort of auto sleep that it goes into and when you 'awaken' the drive to use it it takes a few seconds to power back up... but that's just my theory. It makes things go very slow when you're working on lots of images on the drive, so any help would be very much appreciated!
What would be causing this momentary freezing as it is accessed? And is there a way to turn this off?

Hi,
I have exactly the same problem... with both my Canvio 1TB drives. (One is a HDTB110XK3BA, the other a HDTC610XK3B1.)
For some reason, NoSleepHD wouldn't install. (Could be because I have a 64-bit system.) As for Linux, I don't have it installed, and I'm no computer technician.
Isn't there a an easier way to get rid of this very annoying problem?
Thanks!

Portable hard drive questions

Okay, so I know nothing about portable/external hard drives. I'm looking into getting a portable hard drive so I can backup my Mac when I move to college and I have a few questions. What kind of portable hard drive is best (I heard that drives above 500 GB require a power outlet so I'll stick to 500 so I can just plug it in, is that right?)? Also, is it possible to set aside a portion of the hard drive just for Time Machine and use the rest for storing needs? Or does the whole hard drive become a backup? I'm also curious as to use FireWire or USB; I have a FireWire 400 and 800 ports on my Mac. Any help would be appreciated so much. Thanks in advance!

In general "portable" external drives use 2.5" Laptop sized drives and tend to cost about twice as much as do "full" sized externals that use 3.5" drives. Or put another way, for the same money you can usually get twice the storage as you get with a portable (e.g. $100 for a 1TB desktop external or for a 500GB portable). Also many of the portable drives tend to be Bus powered, meaning they run off the USB or Firewire port for power and data. The desktop ones usually have a dedicated external supply. Unless you plan on actually carrying the drive around with you a lot, you will get a better deal on a desktop sized external drive. Many of them are actually rather compact to begin with, no so much that I would want to carry it around in my backpack all the time, but certain portable enough to go from college to home and back again a few times a year.
In general, Firewire drives tend to be a bit faster for sustained large file transfers than USB2. They are also much better for doing video downloads directly from a camcorder to the external drive via Firewire (talking about MiniDV camcorder and other tape based systems). They, Firewire enabled drives, also tend to cost a bit more for the same capacity than USB2 drives. My advice is if you tend to do a lot of video editing off a tape based camcorder, then you NEED a drive that can connect with Firewire. If you mainly will be doing basic Time Machine stuff and other simple file storage work, etc. then Firewire is nice if you can find one for a good price, but USB2 will do the job just fine.
When you get the drive, you plug it in and power it on and the drive will simply show up on your desk top much like your internal drive. At this point, there is a good chance the drive is formatted in Windows format. If you plan to use it only with your Mac, it is a better idea to reformat it in Mac format. For Time Machine it HAS to be in Mac format.
So second thing to do is... Applications folder -> Utilities folder -> Disk Utility.
Select the new drive and then go to the erase tab and pick the option to format it as Mac Extended (Journaled) and let it format. Should take all of about 10-20 seconds.
I believe you can use the same drive for Time Machine as well as other storage. You may want to partition the drive into two sections and dedicate one to Time Machine and use the other for whatever you want. But I believe you can keep it all on one partition if you like.

Portable hard drive no longer requires password to decrypt it - security risk
