External HFS encrypted password change & Drive mounting in Disk Utility without password

I have two questions:
1. I have an external HFS encyrpted drive that was encrypted via Mavericks Disk Utility. I have the password for it in 1password but I cannot cut and paste it when it attempts to mount. It is a very long password and it would not be practical to type it manually. It seems that Apple does not permit pasting such passwords (I have also tried to copy the password to a sticky note and then into the drive mount password prompt with no results, thus it is not unique to 1Password). At any rate, to remedy this situation, I would like to change the password to something smaller and memorizable (which is very very unfortunate as I find this a gaping security issue for who, in their right mind will manualy type in a 60 character password every time?). I have not been able to locate a method to change this external drive's password. Any assistance would be greatly apprecaiated.
2. Alarmingly, I AM able to mount the drive WITHOUT entry of the password if I do a verify disk and repair disk. This is horrifying. This means that without any password someone can mount the drive just by running these utilities.
Thanks in advance.

You wrote: "It's definitely formatted for windows...I have Disk Warrior, but it doesn't see my drive "DiskWarrior only works on disks in Mac OS formats, e.g. "Mac OS Extended" (aka HFS Plus or HFS+), "Mac OS Extended (Journaled)." It won't fix disks in MS-DOS/FAT32 format.
There are PC-specific disk utilities, akin to DiskWarrior for Mac, so if you have a PC as well, a PC disk utility might help repair the directory corruption if run from a PC.
External drives, whether they're formatted for PCs or Macs, can be subject to the same causes of directory corruption discussed in See my "Data corruption and loss: causes and avoidance" FAQ. Some of those causes have nothing to do with hardware failure and many are preventable.
Good luck!

  • Why won't my external hard drive mount in Disk Utility even when it shows up on the list?

    Hey all,
    For the last few years I've used a Samsung S2 1TB external harddrive to back up all my files, this includes photos, music and a vast amount of resources required for Uni. However I plugged it in for the first time in about two months and discovered that neither my Macbook Pro (late 2011) or my Mac Mini (early 2013) are able to mount the hard drive.
    It shows up in Disk Utilty however the harddrive is greyed out and when I manually try to mount it I get an error message saying that it can't be mounted and to use the first aid 'Repair disk permissions' feature which would be all good and well were that not also greyed out.
    I've read a fair amount on this forum that suggest that Mavericks has caused quite an issue with harddrives and although I don't know for sure, the harddrive did stop working at a very similar time to when I updated. I've sinced used the basic version of 'Disk Drill' on the harddrive and all the files show up perfectly which leads me to believe that perhaps the issue isn't with the harddrive itself but perhaps a compatibility issue.
    I was just wondering whether anyone had any advice or had suffered a similiar issue, preferably in relation to the Samsung S2 harddrive. The partition type is a Windows_FAT_32 and it's a USB hard drive.
    Thanks in advance!

    Because there's a problem with the disk's directory structure; these are often the result of improperly unplugging drives or forcing a computer to shut down. Proceed as instructed, or try using a more powerful utility such as DiskWarrior to repair it.

  • My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you

    My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?

    Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
    Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
    Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
    Quit and you should be able to install OS X now with your Apple ID and password.

  • Internal hard drive does not mount in disk utility

    My internal hard drive no longer mounts in Disk Utility. It is grayed out. I have extraordinarily frequent spinning beach ball/freezes, in Safari or Apple Mail. The most recent symptom: upon rebooting or just starting up, I see flashing black on the display. This has been occuring for more than six months. Of course, I have made total and frequent backup's. I bought new RAM, but have not yet installed it, and I susect this might help. I have done repeted troubleshooting many times each:  Apple's Disk Doctor, Repaired Permissions, Reinstalled the Mac OS, safe boot, Alsoft's Disk Warrior, Apple's longer Harware Test, etc. I have worked as a new user, too. All tests done report that all is well. What od you thnk the problem is? Must I drive 1.5 hrs. each way to the Genius Bar at my nearest Apple Store? Might I try to erase the hard drive as a fix? I hate to do this, only as a last resort, as it is so time-consuming. Should I just update my Mac OS? Please advise, out there, if anyone can offer any advice, I would be greatly appreciative.

    The list of issues you posted probably would not get shorter if you attempt to 'upgrade them' away, as usually that kind of effort is not effective yet may expose more of the same problems while not necessarily revealing the original weakness. Another OS X installed over a set of problems seldom helps.
    How full is the hard disk drive? If it is too full, or has been very busy in use several years, it may be time to replace the HDD and perhaps put a larger capacity one in the computer. And if the main computer hardware checks out OK (tested under a variety of duration and stress tests) then also consider a RAM upgrade if the device is not already at the maximum capacity.
    When was the last time the hard disk drive was devoid of content, maybe wiped -- erased and reformatted by a third party disk utility or have a utility overwrite the entire HDD with zeros? This used to be a common tech service in the course of a major effort to restore a Mac. Or Defragment?
    If you can do the latter, this could help resolve bad sectors and remove old data or corruption on the hard drive. Or get a new HDD and before committing a new OS X install & apps to it (or a re-clone of a complete backup) test the drive and be sure it is ready for use. Not all new drives are perfectly ready; some need to get exercise first.
    I'd bet on a new hard disk drive of larger capacity (also note spin RPM rate and data speeds) and a full RAM upgrade.
    If you have a backup clone on an external hard disk drive (in a boot-capable enclosure) you could really go to town and before you erase the main/only hard drive, make a backup clone and test its ability to boot the Mac. Or put the old drive and content in a suitable boot capable enclosure of the kind with its own power supply, and deal with it later.
    Then consider a later version OS X -- whatever most recent version that model can support... {edited}
    Good luck & happy computing!

  • Internal hard drive fails to mount in Disk Utility.

    My internal hard drive fails to mount in Disk Utility for the past year, so I cannot verify it. However, it does mount in Disk Warrior. (1) I am concerned that it will not mount within the Apple software, and what that bodes for my computer. (2) I also have MANY spinning beach balls daily and have to use the power button to reboot. I just bought extra Crucial RAM and have yet to install it. Somehow, I don't think it wil help my issue # 1 though. Please advise, anyone out there! Thank you.

    No, there are never any errors like that. Also, I have upgraded the Mac OS from 10.5 to 10.6.8. That did nothing. I backed up my Users = Christina folders to a good, 15 year old Firewire 800 La Cie 1 TB  external hard drive. I also tested using the Apple Hardware test, which showed no problems, and Alsoft's Disk Warrior and defragged, and fixed a very minor issure re directory count, probably resulting from many improper shutdowns lately due to frozen spinning beach balls. None of these procedures alleviated the issues, and I still have the same issues: mainly that super-frequent spinning beach ball. Do you think I ought to install that new RAM sitting here finally? Perhaps it is a lack of RAM??I only have 2 lousy GB's of RAM after all! Thank you so very much for a reply.

  • Drive visible in Disk Utility but not Finder.  Why?

    I have a PowerMac G4 (mirrored drive doors) with 4 hard drives installed. 3 of the drives are set-up in a striped RAID array and the other one is my boot drive with two partitions. One one partition, I have OS X 10.3 and I can see the RAID drive fine. On the other partition, I fresh installed 10.4 but the drive does not appear on the desktop. Strangly, I can see the drive in Disk Utility and it shows me the mount point. I can even unmount and remount it but it still does not show up in the Finder. I had 10.4 server installed prior to the fresh 10.4 (not server) install and that showed it fine. I tried to see the drive in Terminal but also does not appear. Why does my drive appear in Disk Utility but not the Finder?

    BDAqua wrote:
    Yes, it needs the path to the drive...
    :-/ Yes, I got the command in completely with the path to the drive like it states in the other post. I have no idea why it didn't recognize the command as I'm not as familiar with UNIX/Linux commands as I'd like to be.
    Anyways... I found the cause of the problem (incase it happens to anyone else). Here's what happened:
    The ownership on the root of my RAID volume was set to be read/write for me (under my proper username) and no access for anyone else including Admin. When I installed a fresh OS, the default user was Admin (who had no access under the previous OS). If I would've taken the time to set-up my proper account (with the same owner name as my previous OS) then it would've been visible again but since I didn't see it under the default Admin account, I stopped there to troubleshoot. Another way to make it visible was just to change the access privileges from my previous OS to be read/write for other users (or at least Admin). I would think that checking the box for "Ignore ownership on this volume" would've remedied that but for whatever reason, it didn't.
    Thank you for all your help. I did learn a little even if it wasn't the direct solution. Now if only I could get Disk Utility to restore my old image without giving me crazy errors... But that's another issue altogether. ;-D

  • "/" symbol where my disk should be mounted in disk utility.

    I have a "/" symbol where my disk should be mounted in disk utility. I was just wondering if this is normal. I feel like it used to be a bunch of numbers and letters (probably saying where my disk was mounted). I have been having a bunch of hardware and CPU issues and maybe this could be why?

  • Missing menu "File|NFS Mounts" in Disk utility

    I had many NFS mounts using Disk utility and I used "File|NFS Mounts" but now that option is missing and I can't see my mounts neither those mounts are working, so I have two questions
    1. Where I can see my old mounts listed?
    2. How can I make nfs mount work?

    The problem is Boot Camp:  It uses a hybrid GPT/MBR partitioning scheme - which ends up hiding the Recovery HD partition - which is an EFI physical partition (neither GPT nor MBR).
    I would expect a new version of Boot Camp to release - like real soon - because of the Recovery HD partition invisibility issue.
    In this article - it is suggested that rEFIt should be used to partition a hard drive that is going to support multiple boots including Mac OS X, LINUX, and Windows. 
    (http://wiki.onmac.net/index.php/Triple_Boot_via_BootCamp)
    The key in the article to using Boot Camp with rEFIt is this:
    "Run the Boot Camp Assistant and create the Windows XP driver cd. Then exit Boot Camp.  DO NOT PARTITION USING BOOT CAMP: you are only using Boot Camp for the drivers, not the partitioning."
    All partitioning is done in terminal mode using the "diskutil" command.
    rEFIt is used to update both the GPT and MBR records so that all partitions will be visible using its "gptsync" command.
    Then - you replace the standard Mac boot menu with the rEFIt boot menu.  THAT will show the Mac OS X partition, Recovery HD (an EFI partition), and the Windows partition.
    My caveat is that rEFIt - which is open sourced and available here:  http://refit.sourceforge.net
    has not been recently updated and tested with respect to Mac OS X Lion.
    Hope this helps!

  • Can I just close disk utility without risking data loss or drive problems?

    I am using disk utility's restore to clone a hard drive to an external drive but it is taking forever (telling me 3 days)  and the cancel button won't work. Can I just close disk utility without risking data loss or drive problems? Force quit? Anyone have experience with this?
    - George

    I spoke with a tech advisor through applecare. Theoretically the source drive should not be damaged if you quit the disk utility application while cloning your drive. More obviously, the destination volume will be unreadable and require a re-format, but in general no major damage will occur. I have quit the disk utility and restrarted, the source drive works as expected, while the desitination shows, "unreadable"
    Hope this helps anyone else with a similar question.

  • 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

  • External hard drive seen in Disk Utility, but will not mount.

    My external hard drive has power and is spinning, but will not mount.  It was fine yesterday.  It shows up in Disk Utility and is verified and repaired.  Tried the drive on 2 other macs with same result.  Tried a new enclosure and that did not work.  Tried all ports...usb and firewire.  Any way to save my data?
    I have screen shot of the partition info from Disk Utility for the hard drive included:

  • Can I REPAIR my External Hard Drive in Disk Utility without losing all of the Data?

    So, here's the story...
    A while back, I made the mistake of throwing my TM backups in the Trash folder. They were "stuck" there in my External Trash FOREVER until I finally decided to do something about it. I read a few forums that gave instructions on how to delete those volumes through Manually through a series of prompts in TERMINAL. This process actually WORKED and removed the files from the trash, HOWEVER, now the Disk isn't mounting properly. After running "Verify Disk" in Disk Utility, It's telling me that the disk needs to be repaired.
    Fearing that my disk may be wiped completely, I thought I'd transfer all the files over to another HD and Repair the Problematic Disk just to be safe.
    But When I try to copy the files over to another drive with ample space, it gives the message "The operation can’t be completed because the selection contains both backup items and non-backup items."
    I am now at a cross roads, because I DO NOT WANT TO LOSE ALL OF THE DATA ON THIS DRIVE!!!!  What do I do??

    Hi,
    If it is not mounting properly but you can "grab" something in an effort to Transfer it, what are you seeing ?
    Can you limit it to different files/folders ?
    Other than that I would try Carbon Copy Cloner (you can Try before your Buy sort of thing)
    Use this to Create the Backup of the drive.
    Then repair drive.

  • HT1782 External HD won't mount, suggests disk utility to repair, but I can't back it up.

    Hello,
    I'm having some problems with my Western Digital My Passport 1TB.   When I plug it in I receive an error that says "the disk you inserted was not readable".  I've read some suggestions that say to you Repair on Disk Utility, but others that say to back it up first.  Unfortunately the disk won't mount so I can't back it up.  Am I best to unplug it and try it on a new machine?  Or verify? Or repair?
    I'm sure this goes without saying, but the contents are extremely valuable to me.  What is the safest method to retrieve it?
    Thanks very much for your help.

    I would try shutting down, unplug the WD external drive, restart and after getting to my Desktop, plug the WD drive in and see if it's mounted and readable.
