My external hard drive appears in bootcamp but not on my mac partition

This is intriguing. I own a macbook pro and run osx 10.6.8
I recently bought a new 1 tb hard drive and partitioned it. (300G for time machine and another for 700G for random things). It was working fine until I tried logging onto my bootcamp partition. I couldn't edit any files (due to the format of the drive), so I decided to relog back onto my mac parititon. Now the disk is grayed out in disk utility, under a different name and a different format type. I can read the files on my windows partition, but I cannot even access the drive on my mac partition. This drive is rather big, and I have no idea how I would even begin bcking it up... ( i don't have any other drives this large..)
Any ideas?
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!

  • My new external hard drive appears in Finder, but none of the files show up in recent documents (today/yesterday/past week)

    My new external hard drive appears in Finder, but none of the files stored on it show up in recent documents (today/yesterday/past week).

    what format is the external drive? How is it connected?
    The drive must be formatted Mac OS extended (journaled) - if it is try Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - from the resulting first aid window repair permissions and if necessary rebuild your database
    Note that multiple libraries is not necessary and is generally a bad idea.

  • External hard drives work on tiger but not on leopard. WHY?

    My 2 external hard drives worked fine on tiger. I had the backup program and used it every week. Now that I loaded up leopard, I cant see the external hard drives. When I take the drives and plug them to my mac book pro which I have not yet upgraded, they come up fine.
    I cant even see them in disk utility
    Please help

    My external doesn't work either. It seems like it is trying to boot, but doesn't. Meanwhile, the Mac Pro churns and the fan goes into high gear. At that time the screen freezes and the little rainbow wheel just spins. The only way I could get the Mac back was to power down with the power button on the front of the CPU and unplug the external drive. It's just a backup drive but I would like access to it. I'm looking to see if the manufacturer has a patch online, but I'd appreciate any suggestions ion the meantime. I haven't upgraded to Leopard yet on my MacBook Pro, maybe I'll wait a few days... Anyone know what to do?

  • My external hard drive works on PC but won't even show up on my mac?

    My external hard drive works on pc but won't even show up on my mac? What can I do?

    If it is in the wrong format it must probably still show up though, if your mac does detect it, go to disk utilities> choose the device from the left hand side > go to the "erase" tab and change format to "Mac OS extended (Journaled) then hit "erase".
    IMPRTANT! : this will erase ALL of the files on your external hard drive
    If this dosent work, make sure your external hard drive's USB port is compatibe with both USB 2.0 and 3.0 and also make sure your mac USB socket isnt damaged either.
    Hope this helped

  • Does my external hard drive have to be always connected to my Mac for T.M?

    Hi there,
    I have a MacBook and I back up my files onto a external hard drive using Time Machine, but when I come to back it up a second time it always say's failed so I have to reformat it and start all over. I was wondering if it needs to be constantly connected for it to work? If that's the case I might as well get a time capsule and do it wirelessly. I would keep it connected if I didn't have to move it.
    Thanks guys for your time and for your comments in advance.
    David.

    No.
    When the backup finishes, are you ejecting the drive before disconnecting it? If so, that's the problem -- OSX can't "close out" the disk properly, so the file system on it gets corrupted.
    If not, A clue may be lurking in your logs. Click here to download the +Time Machine Buddy+ widget. It shows the messages from your logs for one TM backup run at a time, in a small window. Navigate to the backup in question, then copy and post all the messages for that run here.

  • Is it possible to boot windows solely from an external hard drive so that it does not affect the internal drive

    Is it possible to boot windows solely from an external hard drive so that it does not affect the internal drive. I already know that you can partition the internal hard drive to do the very same. Idon't want to use any of the internal space to run windows so I'm asking if it is possible to use a flash drive or external drive through USB to run windows when it is plugged in.

    Read https://discussions.apple.com/thread/5043762?start=0&tstart=0 to discover you can't do it.

    Click on it, choose Get Info from the File menu, and check the format.
    If it's formatted as NTFS, reformat it as MS-DOS, exFAT, or Mac OS Extended (Journaled) as desired, or install software such as Paragon NTFS on the computer.
    If it's formatted as FAT32 or exFAT, use the Disk Utility's Repair Disk command on it; this may also happen for a flash drive which is about to fail.
    If it's formatted as Mac OS Extended, click Authenticate and provide your administrator password, or change the permissions on that specific folder in its Get Info window.

  • Why do files on an external hard drive appear as alias when connected to Time Capsual's USB?

    Situation:
    I have an old MacBook Pro (2008) and all of its USB and CD ports have stopped working (only the Ethernet port works). As a workaround, I purchased a 2TB Time Capsule, connected it via Ethernet to the MacBook Pro, and set up a wireless network that my MacBook Air (2010), ipads/pods, can connect.
    Attempting to Accomplish:
    1. Provide a back-up for my Pro since I cannot connect via USB
    2. Move photos off my Air (to free up space) and combine with my Pro's library
    3. Share files, music, and photos between all my devices (stored on both my Pro, Time Capsule, and external Maxtor hard drive)
    Problem:
    My last Pro back-up was to a Maxtor external hard drive. Also, all my Air photos are on the same external hard drive. I connected this hardrive to the Time Capsule. When I accessed the Maxtor from the Pro (through my new airport network) I can see the file hirearchy, but when I drill down to my Air's iPhoto library (back-up, latest, user, x, photos) the files appear with the alias symbol on them. The message I get when clicking is something about them being no longer connected. HOWEVER, when I attach this Maxtor via direct USB to my Air, both the Air backups and the Pro back ups appear as real files (no alias icon) and can be opened and transferred. When my Pro's ports worked I frequently shared files this way with no alias icons.
    Disclaimer:  I'm mac-savy enough that the genius bar is adding no real value/help, but not nearly as technical as most people on this board. And I'm very un-technical with networking. So if you can point me in the right direction, please "speak" simply =)

    Ok, confirmed. It is NTFS and according to the permissions I can only read it. The frustrating thing is that it says:
        - Capacity: 74.53 GB
        - Available: 50.35 GB
        - Used: 24.18 GB on disk
    and yet at the bottom of the file list it shows "0 items"
    Now the dilemma. The harddrive on my Windows laptop is very small (30GB) so I cannot copy all of my pictures to it. I could hook the old harddrive and the new harddrive up to it at the same time and move them from old to new, however...
    The new harddrive is supposed to only be for the Mac so my intention was to format it that way. Because I am not sure if/how I am going to need it to resolve this issue, the box hasn't even been opened...so the first question is long term would it be better to have the new harddrive MAC or FAT32 formatted?
    I have been assuming that Mac formatting was the preferred route so I am still brainstorming on ways to get the files straight from the old harddrive to the Mac. Could it just be a matter of the files being hidden on the old harddrive? How do I unhide them?

  • Hard drives appear on desktop, but are inaccessible

    Hi.
    I recently bought a 17' macbook pro 2.6. I previously had a g4 with four hard drives in it, so I took a couple of them out and put them in external cases. I also have a few external hard drives that were always externals (never in the g4).
    The problem I have is that I cannot access one of the formerly internal hard drives. It appears in disk utility and I verified it and there was a minor repair needed (I forget what), so I used the repair function and nothing has changed. The drive icon appears on the desktop, but not under "devices" in the finder window. When I double click on the drive on the desktop, any open finder windows disappear for a few seconds, then reappear, but the drive does not open.
    The same thing happens about half of the time with another external drive that was always an external drive. The strange thing is that, even if I can't open the drive, iTunes can access the music files and library on that drive. These drives work fine on my wife's macbook (2.16, running 10.4).
    And as if that weren't strange enough, about half of the times that I select "documents" from the "places" menu in the finder window, the same thing happens (finder windows disappear for a few seconds and the documents folder doesn't open), yet I can access my documents folder through my home folder.
    The other drive I pulled from my g4 is currently my time machine drive and has no similar problems. Two other external drives also have no problems.
    Does this ring any bells?
    Thanks,
    Bruce

  • New cube laptop - not showing Maxtor external hard-drive in windows explorer, but showing up in Device manager.

    Hi
    If anyone is able to give me some advice I'd really appreciate it. I have seen similar issues on here and tried uninstalling then re-installing the driver which seemed to fix the similar issue on someone's Windows 7 system but it doesn't seem
    to have worked for me. I also tried using the usb 2 drive rather than the usb 3.
    I have a new cube laptop with Windows 8 (which I'm not used to yet at all) and am trying to access the files from the Maxtor hard-drive from my old pc. The hard-drive does not show up under file explorer but seems to appear in device manager. The
    laptop makes noises occasionally as if it is detecting some hardware but not showing it.
    Can anyone suggest a fix?
    Thanks in advance

    Hi,
    Apologize for the late reply.
    How about the situation by now?
    Could the external hard drive be shown in the
    disk management?
    Or take a look at the format of that hard drive(list disks) with diskpart command:
    A Description of the Diskpart Command-Line Utility
    Check if the format is NTFS.
    Also please take a look at the following article:
    Help! After installing Windows 8.1, my USB drive disappears or file transfers

    Hope this may help
