My external hard drive disappeared on Windows 8

it had worked fine until now.  Windows 8 updated itself today and the external HD is nowhere to be found.  I attached it to another computer and the external drive works fine... all the files were there, accessible and no loss of speed.  So
it is definitely a windows 8 issue.
The specs for the external drive are as follows:
-  2.5" SATA hard drive by Toshiba - MQ Series-
-  i.t.works HDD enclosure model 1274155
I uninstalled the device as i saw it hidden (sowed as "unconnected") and restarted.  The restart did nothing.  In fact, i can't find an uninstalled "mass storage device" in the device manager either.  
The blue light on the device is on... so it is definitely connected to the computer.  When i take attach and detach it from the USB port, the computer gives a warning sound.  So where is this thing?!?!  Very frustrating.

Maybe the device is not compatible with Windows 8?

  • Internal & external hard drives disappeared in Finder

    It happened yesterday on my G5 running 10.4.6. I have 2 hard drives inside my G5 and one external hard drive connected with firewire 800. The second hard drive and the external hard drive disappeared in Finder. But the one that has the system on it is fine. They did show up in Disk Utility. But it said they are both "not mounted".
    When I tried to repair them in disk utility, it said:
    "Checking HFS Plus volume.
    Invalid B-tree node size
    Volume check failed.
    Error: The underlying task reported failure on exit
    1 HFS volume checked
    1 volume could not be repaired because of an error"
    Does anyone know how to fix it? I have lots of stuff in those hard drives.
    Thanks

    Sounds like you have a major problem that Disk Utility cannot fix. This has happened before to other users. I suggest you get a copy of DiskWarrior and that will probably fix it. You can read about/buy it here:

  • How can I transfer files off an external hard drive formatted for windows?

    I just bought my first mac (yay!) and am trying to transfer my files off of my old pc.  The problem is that I stored all my personal files on an external hard drive, which is of course formatted for windows.  My mac will open it, but it is "read only."  I tried plugging it back into my pc and using the Migration Assistant to transfer my files over, but it was not detected (rest of the pc was).
    However, the second time I tried plugging it in to my pc, it told me it would need to be formatted first.  Obviously my mac has changed something on it, and now all my personal files are on a hard drive that is unusable by either my old pc or my new mac! 
    Any suggestions would be appreciated!  Heads up though, I am not especially computer literate, and my pc needs to stay intact as the husband needs it and some of the programs on it for school.  Also, I have a second external hard drive that is brand new with nothing on it, if that will come in handy.
    Thanks!

    Format the extra HDD to EXFAT as previously indicated.  There are two ways that can use to transferr the data. 
    1.  Connect both drives to the PC and the copy the files to the newly formatted (EXFAT) drive from the HDD with the data .  Then connect the EXFAT drive to the MBP and transfer the data to same.
    2.  Connect both drives to the MBP and open DISK UTILITY>RESTORE.  Drag the drive with the data on it to the 'Source' field.  Drag the EXFAT drive to the 'Destination' field.  Click on the 'Restore' butt is on.  After the transfer has been completed, close DISK UTILITY and place the data on the MBP where you want it.
    Ciao.

  • Why have my TV shows on my external hard drive disappeared when I've deleted them from my iTunes library?

    I am trying to free up space on my internal hard drive (MacBook Air).  I copied my iTunes TV shows onto an external hard drive, following all instructions carefully.  They were all there on the external drive - I opened a few and they played perfectly.  I then went back into iTunes and deleted the shows, then emptied trash.  When I went back into my external hard drive, all the TV shows had disappeared!  Am now in process (yawn) of downloading the shows again onto my laptop, rather defeating my object of freeing up space.  Can anyone tell me what I have done wrong?

    Hello Janeburows,
    You might have setup your iTunes in such a way that you store your Media files on your External Hard Drive and if that is the situation then whenever you delete anything permanently from your iTunes on your Computer when the External Drive is connected then the Content will get deleted from your External Hard Drive. To verify the Location for the Media files which you have on iTunes do the following.
    Open iTunes > Preferences> Advanced and you will see it under iTunes Media Folder Location

  • Help with using external hard drive to boot windows on PC

    Hi,
    I'm not sure if this is in the right place, so apologies in advance if not. I've looked around the internet for a good while now, and I haven't found anyone in my exact position.
    My PC's hard drive (running Windows 7) recently died; long story short, I am attempting to reinstall windows. The only other computer I have is this MacBook Pro, on which I have an .iso file of Windows 7. So I want to use my external hard drive (WD 500GB "MyBook") as a boot device so that I can install Windows onto my new internal hard drive.
    The problem I am having is that, well, nothing seems to be working. Every time I try to load the .iso onto my external hard drive and boot my PC with it, either a blank screen appears or it says "missing operating system".
    I have made sure that the BIOS is running the external hard drive as its boot priority.
    I have tried using Disk Utility to partition the external drive, then using 'Restore' to load the .iso onto the partition, to no avail.
    I have tried simply dropping the extracted .iso files onto the hard drive, this doesn't work.
    I have also tried changing the file system of the external hard drive using the 'Erase' feature (NTFS-3G (using an addon), FAT32, exFAT, all of the others), but I notice that whenever I use Restore after doing this, the file system seems to return to Mac OS Extended, which might be why it isn't booting up on my PC. Is there any way I can succesfully partition the external hard drive in a format that will allow Windows 7 to boot (such as NTFS?), and is Disk Utility even the right program to do this?
    If you want any more information from me, please let me know and I'll do my best to provide it - I'm not the most advanced mac user in the world, but I've spent days trying to fix this problem and nothing, no combination of anything, seems to work at all. So any help will be greatly appreciated!
    Thanks

    Here is a quick suggestion for you:
    Download Virtual Box (free PC Emulator for Mac) and install Windows 7 on your Mac (don't worry about activating it yet, as you don't need to keep it more than a few hours).  You can tell Virtual Box to use the ISO file as the DVD drive for your virtual Windows computer, so no need to burn a disk.
    Search Google for creating a bootable USB installer for Windows 7.  I found a link that gave good instructions on how to do this using DiskPart.
    Follow the instructions to make the bootable USB stick for installing Windows 7 using your virtual machine you created above.
    Use the USB stick to install Windows on your new PC.
    Remove the virtual Windows machine from your Mac.
    Remove Virtual Box from your Mac.
    I found a set of instructions and built an installable USB stick last night that worked great for installing Windows 7 Pro (64 bit) onto my older ThinkPad I had sitting at home.  The USB installer also installs in about half the time as a DVD install.  The only reason I have you create the virtual Windows PC is that all of the instructions for makeing the Windows install USB stick are written assuming that you already have access to a running Windows PC.  By doing this install, you have up to 3 days before you would need to activate it and you can build the installer USB stick and remove teh virtual computer long before that.

  • Can't access my apple lossless files on external hard drive after reinstalling windows 8.1

    Hi guys
    New to this. I reinstalled windows 8.1 after windows continually asking me to change my password after not recognising it despite it being the right one. All my apple lossless tunes are on my external hard drive. Windows keeps saying 'I don't have access to this file currently'. I tried right clicking on hard drive, clicked properties, and tried assigning administrator rights to everyone but still no luck. Contacted windows who said it was an apple issue so here I am.
    Can anyone help. I've got 900 albums on this hard drive and the thought of ripping them all again is stressing me.
    Thanks guys
    Stuart

    Changing the path to the media folder doesn't change which database iTunes opens. If your original database is on the external drive then shift-start-iTunes and use the choose option to open it. If you no longer have access to the original database shift-start-iTunes and create a new empty library at X:\iTunes, where X: is the external drive letter, ensure the media folder is set to X:\iTunes\iTunes Media, move all of your content inside X:\iTunes\iTunes Media, use File > Add Folder to Library > X:\iTunes\iTunes Media. See also Recover your iTunes library from your iPod or iOS device. There are some scripts near the end that can extract ratings, play counts and playlists from your device and the rest of the tip explains how you backup and restore the device with the new library to avoid losing data.

  • USB keys and external hard drives disappear after 30 seconds to 1 minute of being mounted.

    I just got my 15' MacBook Pro refurbished (by Apple), and everything is working well except my USB ports. My USB keys appear for 30 seconds to as much as 2 minutes before disappearing from eveywhere, my desktop, finder and disk utility.  I have a 1 TB WD passport for mac that also has the same problem, but can stay on the desktop and copy files for around 10 minutes. Then error -36 shows up, the hard drive disappears from the desktop and finder, but only appears in disk utility. It is powered as well, The light is currently flashing indicating it's receiving power as I am typing this. But still, no way i can copy anyhting onto it.
    I have searched and searched for the solution to this problem, I have tried using apple script to find "invisible hard drives." and that doesn't work either.
    On my windows partition in bootcamp, all usb keys work perfectly fine.
    Is it because the USB ports are out of energy and dying? If so, should the refurbishment have covered that and replaced them? (Note: refurbishment included everything from my Keysboard to my battery to my Optical drive and cable optical drive flex)
    Is there anything I can do to fix this problem on my own?
    Any help I can get would be greatly appreciated.

    Hi wdmpfm,
    Here is something from an earlier post on the -36 error that may help to identify the issue:
    A -36 is a disc I/O error. You might have a corrupt file, or a corrupted drive. Try creating a new file and see if you still get the error. If you do, it might be wise to run a Disc Repair program to see if it can find any errors that it can fix.
    And one from another thread:
    You need to format your drive correctly. New drives come formatted for Windows, & then they seem to work — but not properly.
    +Applications > Utilities > Disk Utility+
    Choose one of the +Mac OS Extended+ formats.
    Obviously first you will have to back-up all the data you have already put on the drive, because it will all be lost when you re-format.
    Hope one of these may help!
    Cheers,

  • External hard drive for both windows and mac

    hello, all - just bought a western digital 500gb my book premium edition external hard drive. will be using for both pc and macbook, not necessarily to share files (though i may on occasion), but rather as a backup. been researching the discussion boards and concluded that i should use it as pre-formatted fat32. few questions...
    1) if i do use to share files, from what i understand i will be able to read windows files with my mac but i can't read mac files with windows (unless i have macdrive installed). is this correct?
    2) since mac can read/write to fat 32, is it necessary to partition the drives and keep the files separated? i talked to a "computer guy" earlier today and he said i should consider having two completely separate external hard drives as having files from two different operating systems on the same drive could cause major problems for both... i didn't really believe him.
    3) i have seen different posts stating using fat32 format for mac limits file size to 4gb. another post said 32gb. which is right? i have os is 10.4.7 if that makes a difference.
    thanks in advance for any insight.

    2 - i don't mind partitioning at all. but he strongly suggested not even partitioning but using two completely separate hard drives. yeah, the 500gb was a bit overkill, so if i can use it for both as opposed to one and buying an additional, i'd rather.
    2/3 - if i partition, is it best to divide it into ntfs and hfs+? or should i keep the pc portion fat32? if the mac portion is hfs+, can i store any size file? i have videos that are anywhere from 10-20gb, and i'd like to get them off my computer and into the external drive.
    thanks.

  • Setting Up New External Hard Drive to Backup Windows and OSX

    I've just ordered a Western Digital My Book Home Edition 500GB external hard drive from Amazon for £79.17 (c/w 1m eSATA to eSATA cable and shipping in the UK). For the time being, I intend to use it mainly for backup. My MacBook3,1 has a 149.05GB internal drive, which is nearly full. I'd used PC's for more than twenty years before rare financial circumstances enabled me to take the plunge and migrate to the Intel-based MacBook last year. Although the migration process hasn't been without teething troubles, I'm glad I've got a Mac and pleased to say I now feel as comfortable using it as I used to feel with PC's. (But it has taken a year of concentrated effort.) The relevance of this is that I have an awful lot of work in old Windows-based programs, which I need to keep backed-up and accessible. The MacBook's internal hard drive currently has 87.88GB dedicated to the Macintosh HD and 60.86GB dedicated to Windows (Vista, Business edition).
    Could you advise me, please: how should I set up the new hard drive with a view to using it to backup the Mac with Time Machine while dedicating a partition for Windows? Actually, I have another desktop with Windows XP, which I'd also like to back up. That hard drive (the XP machine's) is 80GB. Presumably, I'll need to set up partitions for: 1) Time Machine, 2) OSX.5.5 bootable, 3) Windows Vista (on the MacBook) and 4) Windows XP (on the old desktop). If I give 80GB to XP and 70GB to Vista, that leaves 350GB (probably closer to 320-or-soGB in reality) for the MacBook. I don't use virtual machines or any other software to access operating systems - just reboot through BootCamp. What's the best way to go about doing this?

  • External Hard Drives Disappear

    I have 2-1TB WD External Hard Drives connected via Firewire 800 to my iMac. They periodically disappear and the only way to make them reappear is to unplug them and plug them back in. I have unchecked the "Put Hard Drives to Sleep" option in the Power Management section of the System Preferences but that does not stop the drives from disappearing. Once they disappear the drives no longer show up in the Disk Utility either.
    This has been an ongoing problem with iMac's since at least September of 2009. This is frustrating because one of the Hard Drives is my TimeMachine. Therefore, the Backups with TimeMachine are no longer Automatic because I have to periodically unplug the firewire and power from the drive and then plug it back in.
    Please resolve this issue.

    Sounds like "the invisibility plague" see Francine's useful tips here.

    Also, not to be the bearer of bad news, but WD drives do not play well with Mac.

  • Is it possible to use an external hard drive as the windows partition with boot camp?

    I am looking to get a Macbook Pro adn was researchin the different software advantages over PC and found a program called oot Camp that allows you to run Windows on your Mac. I thought that this was interesting as it was sort of the best of both worlds. I wanted to know from people who have used this before: How well does it work? Does it slow down the computer at any noticable rate? Etc.
    The last question that Ive been trying to find an answer to, but have no conclusive results, is wether you are able to select the partition as an external hard drive or not. Also how it affects your ability to use an external drive as well. Answers are much apreciated, thank you.

    Welcome to the Apple Support Communities
    Boot Camp is an application that emulates a BIOS so you can install Windows on a second volume on your hard drive. It can't be installed on an external disk because Windows can't be installed on an external hard drive. It works well if you need performance
