My external USB drive is not recognized by Win XP

Hi!
I have an external USB drive that is HTF+ formatted. It is not recognized by Windows XP. If I start the windows disk manager it gives me the option to initialize the drive. Do I dare to do this? Will it not erase the information on the drive?
Thanks for any help!

Hi Anders and welcome to Discussions,
I have an external USB drive that is HTF+ formatted. It is not recognized by Windows XP. If I start the windows disk manager it gives me the option to initialize the drive. Do I dare to do this? Will it not erase the information on the drive?
Yes it will !!
Although with the BootCamp 3.0 Drivers (from the OSX Snow Leopard DVD) and the 3.1 Driver update (downloadable) Apple has introduced read-access to HFS+ partitions from Windows this feature seems to have some serious problems for some people.
Personally I see this feature as "experimental" at the moment.
XP itself knows nothing and therefor can not use/see HFS+ partitions and GPT (GUID partition table) harddisks.
You might wanna have a look (or buy) at MacDrive http://www.mediafour.com/products/macdrive/ which right now is the better solution.
Thanks for any help!

Hope it helps

  • My external hard drive is not recognized by my computer.

    My external hard drive is not recognized by my computer. I used it earlier and it was fine however my computer froze and I unplugged my hard drive without properly ejecting it. Now when I plug it in nothing pops up. I've tried on three different computers and no luck. I hope this is fixable! Please help.

    Care to share which OS you are using?

  • Is ReFS on External (e.g., USB) Drives Still Not Supported in Win 8.1?

    I've been running an internal disk drive on ReFS under Windows 8.1 since late last year, and have had nothing but perfect operation from it.
    I know that originally, when Win 8 came out, it was not possible to format an external USB drive to ReFS.  It would clearly be a good choice, given that an external drive might be more prone to taking on errors than an internal one.
    I was just wondering whether the restriction might have been lifted in Update 1, and an external drive can now be formatted ReFS.  I am going to try when I get a little time, but I was just wondering if anyone's already braved the territory.

    Follow up:
    Upon a reboot after updating some other software, the system did not come back up right with the "MiniNT" registry tweak listed above.
    Some problems noted:
    1.  Drive letter H: ended up assigned to my System Reserved partition instead of the USB drive, which could not be seen.
    2.  Some applications failed to start with messages like "The procedure entry point _ftol2 could not be located in the dynamic link library C:\Windows\SYSTEM32\comdlg32.dll".
    3.  The system had trouble accessing the event logs with error -50.
    4.  CHKDSK showed some problems on drive C:, but could not correct them.
    Removal of the MiniNT key restored proper operation, and the ReFS formatted drives are still available.
    Make SURE you remove the "MiniNT" key after formatting is complete if you use the tweak at the WinAero site to enable ReFS formatting.

  • EXTERNAL USB Drive will not open with Snow Leopard

    External USB drive will open with SL. The drive icon appears on the desktop. When I click on it, Error message, "The alias USB Drive can't be opened because the original item can't be found." When I click on "Fix Alias", a window pops up and shows the usb drive in a list but does not respond when I click on it. I then tried disk utility and tested the disk and it tested OK. The drive still will not open. This problem started after I installed Snow Leopard. Need Help.

    At the auth prompt, I input my credentials.
    The error pops up, same as original poster.

  • External USB drives will not mount under Mountain Lion

    Since upgrading to Mountain Lion, two external USB2 drives that I have will not mount and cannot be viewed in the Finder.  The same occurs on a 2012 MacBook Air, a 2009 iMac 27 and a 2010 MacMini, all running OS X Mountain Lion version 10.8.2.
    Both drives are Samsung Story external USB drives (one is 1.5 GB and the other is 2 GB) and both have been formatted using Mac Disk Utility with a single Mac OS Extended (Journaled) partition, one using Snow Leopard and the other with Lion.
    Both still mount correctly on a friends MacBook Pro that is still running Snow Leopard, and I had no problem with the same drives under Lion.  Interestingly both can also be connected to Time Capsule USB port and show up correctly.
    Both drives mount correctly under Windows 7 on BootCamp partitions that I have on both the 2012 MacBook Air, a 2009 iMac 27. These BootCamp partitions have Paragon HFS+ installed so I can read Mac formated drives.
    Both drives show up in Disk Utility, but when attempt to mount the drives I get the message "The disk could not be mounted.  Try running First Aid on the disk and retry mounting." I can run Repair in First Aid on the disk and get the message that the volume appears OK, but again have the same problem when I attempt to mount the disk.
    I have also tried using Disk Utility 3,2, but still cannot mount the drives, though the program indicates there is no problem with the drives.
    I have other portable USB including a Samsung portable USB2 drive, and two external USB3 drives, and I don't have problems with them.
    There is clearly a problem with Mountain Lion with accessing (mounting) these Samsung Story USB drives, and the problem appears to be with Mountain Lion itself as the problem did not occur on the same Macs with Lion and does not occur with Bootcamp partitions on the machines.
    I have a lot of time searching forums, but I have not found anyone with an identical problem.
    I sure hope someone can help or that Apple come up with a fix for this issue which has only developed since the update to Mountain Lion.

  • External hard drive is not recognized in Migration Assistantt

    I had my hard drive replaced on my iMac, Mac OS 10.4.11, Snow Leopard.
    I backup my computer using Time Machine onto an external hard drive.
    In Migration Assistant, the external hard drive does not show up. There are no choices to choose to migrate from.
    Any suggestions please!

  • External Hard Drive suddenly not recognized

    I have a WD 500GB external hard drive that I use to back up my data. I only have one hard drive as I'm currently living abroad and couldn't bring a 2nd with me.
    I plugged in my external last night to back up my MacBook Pro and it backed everything up. I even went into Time Machine to go back and restore a file or two and that worked without problem. I have been using this drive for about a year to back up everything on my Mac and, although sensitive, it seems to work okay.
    I plugged it in this morning and nothing. My Mac will not recognize that the drive is not plugged in in Time Machine or in Finder. If I go to Apple Logo > About This Mac > More Info... > Storage tab, it just shows my internal hard drive and my CD/DVD drive. If I click on Disk Utility with the drive plugged in, it shows my Hard Drive (Macintosh HD) with two icons, one inset below the other and both in black font, and then my external hard drive has two underneath, but only the top one is black font - the one underneath is greyed out.
    It goes like this:
    250.06 GB Hitachi...
         Macintosh HD
    500.08 GB WD My Passport
         Time Machine Backups (greyed out)
    Superdrive (greyed out)
    When I clicked on the 500GB one and told it to repair/verify it said the disk was working fine. I tried unplugging and replugging in the drive (it is not recognized in Finder so I could not properly eject the disk). I restarted my Mac with it unplugged and plugged it in afterward and nothing.
    The HD itself is working, the light is blinking (not solid) and I can feel the hard drive spinning, but I'm at a loss as to what to do to get my Mac to recognize it again.
    Any suggestions would be helpful.
    Thank you!

    I also wanted to add, when I click on the greyed out Time Machine hard drive that's listed and then click "Info", this is what it says:
    Name : Time Machine Backups

  • My external hard drive is not recognized

    I have the apple external disk drive.  I have used it numerous times.  I just plugged it in and the computer is not recognizing it.  I have tried both USB ports.  How can I fix this?

    A: USB desktop or 2.5" port powered?
    B: did you just install mavericks
    C:  DOES IT show in disk utility?
    Can you confirm it on another Mac?
    Apple doesnt make HD, what HD is it marked as?
    Likely its a dead SATA bridge card, a very very common problem with USB and external HD
    see here:
    Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD

  • External hard drive is not recognized after attempt to format

    I just got a new macbook and couldn't use my external hard drive because it was formatted on a PC and only allowed me to read the data. I backed up the data on the 250gb hd and then used Disk Utility to erase the hd and format it as "Mac OS extended (journaled)." After beginning, Disk Utility stopped working and showed up as "not responding" in the Activity Monitor.
    Now the hd does not show up on the desktop and can only be seen in Disk Utility. If I try to erase again or partition the hd the utility stops responding. If I try to zero out the drive it continues to say "preparing to zero" indefinately. Now the hd is also not recognized by windows except in the windows disk utility, but it does not even give the option of formatting/initializing it, so that is not an option.
    Has anyone ever seen anything like this before, or have any idea of something that I haven't tried yet. I really want to get the drive working and have exhausted all the ideas I can come up with. The internet has not provided too many ideas either.
    Thanks so much for your help.
    Black MacBook   Mac OS X (10.4.6)  

    I have crazy solution to format it to FAT 32, it work a couple times on my several MAxtor, and Western Digital HD. But this is the last resort and if you are not handy and familiar, don't do it.
    It happen on my external HD, so I crack the enclosure open, pulled the HD out and attached it as internal HD on a PC after adjusting the jumper to master and make sure no other HD attached to the motherboard. Make sure the motherboard detected (you can see it from bios menu).
    Insert a bootable installer disk before XP ('98, ME, or 2000), and start from there until a promt comes, and type fdisk and you delete the old partition and create a new partition and restart once using the disk still and format it using FAT 32.
    After that you put it back to the enclosure, and mount it to MacBook as a new HD with default factory format.
    If you don't have the installer disk, this might help :
    http://www.bootdisk.com/
    But if your maxtor still under warranty better talk to them first and they might willing to reformat it for you.
    Hope this help your external back and let you use it on your MacBook.

  • My external hard drive is not recognized by Time Machine; "The backup disk is not available" according to Disk Utility

    I'm not completely tech savvy, but I'm having troubles with my external memory & time machine.  I'm a student, and thus its very important to me to be able to back up my computer.
    I wanted to back up my Time Machine the other day.  I clicked the icon at the top of the page (beside the battery icon, etc.) and the message "The backup disk is not available".  I have a 500GB Seagate passport (ie: http://www.bestbuy.com/site/Seagate---FreeAgent-GoFlex-500GB-External-USB-2.0-Po rtable-Hard-Drive---Silver/9929098.p?id=1218196478444&skuId=9929098)
    My macbook pro is version 10.7.5 Mac OS X Lion.  My external memory is only about a year old. It hasn't been dropped or anything; it permanently sits secured to my desk.
    What appears when I click "Repair Disk":
    Verify and Repair volume “Time Machine Backups”
    Checking file systemChecking Journaled HFS Plus volume.
    Detected a case-sensitive volume.
    Checking extents overflow file.
    Checking catalog file.
    Incorrect block count for file shutdown_time
    (It should be 1 instead of 0)
    Invalid node structure
    Rebuilding catalog B-tree.
    The volume Time Machine Backups could not be repaired.
    Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
    After clicking "Repair Disk" this message pops up: "Disk Utility Stopped Repairing 'Time Machine Backups'  Disk utility can't repair this disk. Back up as many as your files as possible, reformat the disk, and restore your backed-up files."
    I don't want to wipe my memory on my external disk just in case the disk doesn't restore (as I do not have another disk to back up my computer on to).
    What is going on? Why is this happening out of the blue? How can I fix this?

    Sounds like it either has, or is about to die.
    If you don't need anything off the old drive, then yes, replace it immediately with something a little more reolaable. I use WD Caviar Black personally. But anything that has a known low failure rate.

  • My external hard drive is not recognized on my new MacBook Pro, even though it is recognized on my older MacBook and other computers. Help?

  • My Passport for Mac external Hard drive is not recognized

    I recently had to purchase a new MacBook Pro, and when I tried to get files off of my Passport for Mac external hard drive.  I get an error stating "The disk you inserted was not readable by this computer."  And when I try to initalize, and verify disk, I get this message "Partition map check failed because no slices were found.".  I have already updated firmware for the external hard drive.  One site I found stated that it could be that the USB port is not strong enough, and I would need a 2.0 Booster cable.  Does anyone know if this would work? 

    What did you old Macbook die from?  Likely the HD in it is still ok,  yes?
    You can remove the HD inside your old dead Mac and put it into a $20 HD enclosure or HD dock, and remove the photos that way, very easy.........IF your old Macbook died from something other than ALSO a bad HD.
    You said----my OLD Macbook pro which recently lost video
    What happened with your old "dead" macbook?  Still have it?

  • Satellite C50-D - External Hard Drive is not recognized

    Have just purchased Satellite C50 D but cannot get it to read or recognise my LaCie hard drive.
    As this has all the data from my previous computer it is rather important. Can anyone provide help and guidance as to how to a) read the drive or b) transfer all the data onto the laptop memory
    Many thanks

    Hi
    The notebook supports 1 USB 3.0 port and 2 USB 2.0 ports.
    I recommend you to connect the external HDD to each port (USB2.0 and USB3.0) just to check if its not compatibility problem. But usually it should not be a big problem to connect an external USB 2.0 device to an USB 3.0 port.
    However, it could be also possible that this external HDD needs more than usual 500mA power provided by one USB 2.0 port. In such case you should use an USB Y cable to connect the HDD to two USB ports.

  • External hard drive is not recognized anymore

    For a couple of months i have been backing up my stuff on an external hard drive (Verbatim) no probs.
    Last time I didn't close the external hard drive down properly. Now my Macbook does not recognize the external HD any more.
    I have tested the external HD on other PC and it still works fine.
    How can I change my settings or do something else to have my Macbook recognize is it again.
    Thanks!

    Whenever an external drive is disconnected without first being ejected or dismounted, file system corruption is a very real, perhaps even likely, possibility. If that has happened you might try repairing it with Disk Warrior:http://www.alsoft.com/diskwarrior/
