Comp not recognizing fat32 hard drive...

refer here: http://discussions.apple.com/thread.jspa?threadID=1437437&tstart=0
The hard drive I told about there that I have formatted in Fat32 (because of going between platforms) is no longer being recognized by my mac... I was in the middle of saving my chopped captures, and it is like the format (fat32) has totally messed this thing up! Its on all cables are plugged in, etc... just in case you wonder this HD is the seagate FreeAgent Pro 750GB st307504fpa1e2-rk

Not to be rubbing it in, though I'm doing all my backups on an NTFS formated disk through NTFS-3G.
But lets focus on you problem, the suggestion by Robert Jarosh1, did it work?
Otherwise, the complaint by chkdsk could very well be that it does not understand the format (i.e. Mac OS ext.), I assumed that it might be an NTFS format issue, I was wrong. Otherwise it could have been a broken/lost partition table.
So, you wiped you computer clean and now it won't recognise the external disk when using the SL installation disk (boot disk)? Just so I got it right.
How about installing the OS from the DVD and see if the OS can recognize the external drive? Then use Migration assistant to restore your system from backup?
Otherwise, try something else just to be sure. Fire up terminal from the boot disk and cd yourself to /Volumes/ to see if the disk shows up at all!
Best of luck and regards

  • Mac Not Recognizing External Hard Drive, I Want to Use the HDD to boot Windows

    Let's get this stuff straight first:
    The Hard Drive is from a PC that I am not using
    The Hard Drive already has Windows 8.1 installed as well as all my documents and data. (from the old PC, of course.)
    It does work, however after connecting it to my iMac (late 2014 / 5K Retina) it isn't recognized by Finder, Disk Utility or the (Option) Boot screen.
    Yes, I understand I will need to install drivers, so I'll need help doing that as soon as we get Yosemite to recognize the HDD.
    What I am wanting to do is use this external drive to run Windows from the boot up screen. But I need OS X to actually recognize the drive in the first place. Then I'll need a little help installing the drivers for Windows onto the Drive, unless those are already installed, since it was originally used in my PC? (I'm not sure how drivers work.)
    Nonetheless, if it's not possible to be used as an external boot for Windows, I'd still like to use it to obtain and store files/documents on.
    Thanks guys!
    -Austin

    How do you have the drive hooked up to your computer? Did you but an adapter? If so, is it one that is supposed to work with a Mac? Did it come with a power supply?
    Some of those USB adapters don't work well with Macs and that could be causing problems. Test it on a PC if possible, just to make sure the adapter itself isn't bad.

  • Not recognizing external hard drive after upgrading to mountain lion

    I recently upgraded to mountain lion.  While my external hard drive originally showed on the desktop it does not anymore,  The hard drive is partitioned between my wife (laptop) and my desktop.  My wife's part does show on the desktop but mine does not.  From reading some of the issues on the Support Community I did a disk repair as it does show up under disk utility.  Although the disk repair was performed successfully, it still does not appear.  I read some other comments about Fuse but I don't understand what this is about.  Any suggestions to get my external hard drive back so I can keep my computer backed up.  Thanks.

    It is powered (the light is on).  I was uploading photos from the drive yesterday, so it worked perfectly fine before the upgrade to 10.6.8 (which I did during the night).  Is there anything else to try before I move it to another computer to see if it works?  Again, thanks.

  • Itunes not recognizing external hard drive

    I have a smartdisc firelite external hard drive that was working perfectly until yesterday when I bought a shuffle and now itunes is not recognizing to go the hard drive to locate the songs.

  • CS2 not recognizing external hard drive as a scratch disk

    I have an external hard drive that I want to use as a scratch disk but while I can navigate to have Photoshop open files from the drive, when I go to my prefs and try and select it as a scratch disk, it's not listed as an option - i.e. Photoshop only shows "start up" and "Mac Hard Drive" as choices. But when I go in that same dialogue box, and look for an additional plug-ins folder, I can navigate to the external drive. It's also doing the same thing for a thumb drive I have and two other external hard drives which mount fine.
    I have restarted the program, removed the Prefs file, and restarted the program again but it still doesn't see any of the external hard drives.
    Any ideas?

    mike,
    Most drives are not optimized for Mac as purchased. Unless marked otherwise, consider that every drive you acquire, whether a fast-spinning hard drive or USB flash drive comes formatted as FAT so it can be recognized and used by both Macs and Windows machines. Use Disk Utility and reformat it as HFS+ "Mac OS Extended (Journaled)".
    Just be aware that if you are reformatting your existing drives, you need to back up your data first or it'll be gone forever.

  • Not recognizing external hard drive

    When I first bought my SimpleTech 320GB external hard drive, it did work. It connected and updated everything through Time Machine. After about, a month, it just did not show up in my Devices or on my Desktop.
    I've tried everything. I went to the SimpleTech site and they said to put it in the direct USB port (which I have been doing). I've tried both USB ports and even got a new USB cord and it's not working.
    If anyone has some suggestions, please send them my way. I'm in dire need of some space on this thing so I can install some updates.

    I am having this same problem all of a sudden. My external hd shows up in disk utility; however, it does not show up under devices or is it recognized any more by time machine. When I try and repair it, the repair fails and list a "invalid node structure" and "volume check failed". I disconnect the external hd's power source and firewire connection, reconnected, and this did nothing.
    Any suggestions would be greatly appreciated. Thank you.

  • 24" iMac not recognizing internal hard drive..

    end of '07 iMac 24" 2.4GHz
    I have been having problems with this iMac since day 1... I'm kind of fed up with it at this point BUT I would like to get it working at least.
    PROBLEM: Yesterday I was working on the ol' iMac and I walked away, the computer fell asleep and when I got back to wake it up it seemed a little off. I restarted and thats when the magic happened. I got the question mark of death. Didn't think it was an issue since I've gotten it in the past. Usually I restart again, maybe reset PRAM, and its fine. Orrrr if that doesnt work I use the Snow Leopard disc or Disk Warrior and it'll work fine. Yesterdays problem was more unique.
    Disc Utility, Disk Warrior, etc are not even recognizing the internal hard drive at all. Nothing. Like it doesn't even exist. When you try and set the start up disk, it's missing from the list. It doesn't make any noise, nothing. It worked fine 5 minutes before that.
    Any ideas? or is it time for the ol' Apple repair shop? Could it be just the drive or something more serious? Luckily I have a time machine and everything should be backed up incase of the worst scenario.
    Any help would be great. thanks.

    It sounds like the drive has failed, you can try starting it with the install disc it came with and trying to repair the disk. The instructions for doing that are:
    1. Insert the Mac OS X Install or Restore disc.
    2. Restart the computer, then hold the C key during startup.
    3. From the Apple menu, choose Disk Utility. Do this in the first screen of the Installer. Don't click 4. Continue. If you click Continue in a Mac OS X Installer version earlier than 10.2, you must restart from CD again.
    5. Click the First Aid tab.
    6. Click Repair Disk.
    7. After repairing the disk, try to start from the Mac OS X hard disk.
    If the drive still cannot be seen then make an appointment with an AASP.
    Regards,
    Roger

  • T61P and Advanced Dock, not recognizing removable hard drive

    Folks,
    I am hoping to get some help with my T61p and Advanced Dock.  The Ultra Bay in the advanced dock is not recognizing hard drives that are recognized although they do spin up.  The light comes on and I can hear the drive spinning.  The same ultrabay carrier works with the same hard drive when inserted into the T61p.  If I insert a DVD/CD drive into the advanced dock, it does appear and I can see it to eject it.  These drives were working in the advanced dock several months ago and no longer work.  Is there a set of drivers for the advanced dock or somewhere I can check to see what is there?  Any help or ideas are appreciated.
    Thanks,
    warren

    So it looks like you do not have a hardware problem, since SeaTools sees the drive. Probably the 1.5 Gb/s jumper is not needed, though it's interesting to know that it might be if the drive is installed in the UltraBay (thanks globalkiwi!).
    It seems to me that there must be a problem with the drive imaging/cloning. Another member is having a similar problem with their R400 and True Image. In that thread, ortegaluis suggested repeating the cloning process with your new drive installed on the internal SATA and the old drive connected via USB. Or is that how you did it the first time?
    It might also help to download a trial of the latest True Image and give that a try... maybe Acronis has fixed some problems with SATA drives?
    Please post back with your progress (and hopefully success). Good luck!

  • MacBook not recognizing external hard drive

  • IMac Not Recognizing External Hard Drive

    Hi friends,
    I recently upgraded my MacBook from 5 years ago to the newest iMac. In doing so, I transferred my computer using Time Machine & my external hard drive. The hard drive is partitioned to allow for storage as well as Time Machine backups. I plugged my external hard drive into a PC to try to access these files and it didn't recognize the hard drive, so I didn't think anything of it and unplugged it.
    Now I can't get my iMac to recognize the hard drive at all. I have gone into Disk Utilities to see if it's listed there, but nothing. It usually makes a lot of noise when it's first plugged in (whirring and sounding like it's about to take flight, etc.) but no sound today. However, the white light that indicates it's on is lit. This could be due to being plugged into the wall, however, and not having to do with being plugged into the computer. (This is a decently old hard drive in terms of technology, probably 4 years.)
    I should have known better than to infect my hard drive with PC cooties. But that wouldn't have wiped everything clean, right? I'm wondering if my hard drive just happened to bite the dust coincidentally around this brush with fate.
    Does this sound like something that is wrong with my hard drive, or with the connection? Any help would be greatly appreciated as I have quite a few files I would hate to lose on the hard drive.
    Thanks!

    Zap the PRAM and Reset the SMC; then, hook up the ext HD, fire it up, and see if that fixes things.

  • Final Cut Pro X not recognizing external hard drive

    I'm trying to create a new event in FCPX and the drop down options on the side of where I want to save is not showing my external hard drive.  I have used other external hard drives in the past and it works just fine.

    Yeah I know but here is what´s happening step by step:
    This is when I open it:
    And then this:
    Here you can see that the ext disk is showing in fcpx. But after 2 sec or so a loadbar pops up...
    And then there is nothing to select. Only the internal drive. I do not understand it.
    It´s never been like this before. But I tried a different harddrive (Lacie Rugged) and that was ok. So it´s only the main project disk(the mother, lacie blade runner) that fail to show inside fcpx.

  • Mac Pro 2008 Not Recognizing SATA Hard Drives After Power Failure...

    So we recently had a weird power "outage" where the power still seemed to be surging some (my monitor was blinking wouldn't turn completely off until I yanked the plug on it), and to my dismay, when the power came back on, I started having boot issues with my Mac. Luckily I had a couple of identical dual-quad core machines sitting around (workgroup environment), swapped my hard drive into one of them, and was back in business on-the-fly.
    However, I'm now trying to troubleshoot the faulty machine (qihout throwing parts at it yet) and am stuck at an impasse. With the hard drive of the secondary machine cross-installed into the one that got "hit" by the outage, I simply got the chime and then it stuck on the dreaded gray screen, and out of all the boot options, the only one that would get me a different result was to try to option-boot into the Startup Manager, which would still give me the gray screen but also a mouse cursor after about a minute. Zapped PRAM... reset SMU... even swapped CMOS battery... all to no avail.
    So I started yanking things. Memory.. video card... and finally the one and only (swapped) hard drive. The last one did it, and I was finally able to option-boot, start up from the Installation CD, and ultimately, D-boot into the hardware tests on the CD. Ran both normal and extended tests and everything checked out fine, with no errors (and based on the potetnial error messgaes I read about, these tests check everything from the logic board to the power supply, and voltage across both).
    Now I'm torn and not sure which route to go from here. Machine seems to operate relatively normally when booting from CD... all hardware tests pass... Super Drive works (not sure it that's SATA or PATA, but guessing the latter at this point)... it just won't take a hard drive (which I verified is fine in another computer), regardless of which of the 4 bays I put it in. I'm also hard presed to believe that the power outage/surges caused the SATA cable(s) to go bad yet nothing else, which still have me leaning towards SATA controller on the board or a power supply issue despite the fact the tests passed.
    Thoughts, opinions, or comments... from experience or otherwise? Thanks in advance!

    Look hatter. I'm not saying it doesn't, but "prevention" is not why I started the thread. It was to troubleshoot the already existing problem, and you suggesting I run out and drop a combined $1000 on UPS units for each of the five 2008 Mac Pros I still have in my department is neither contributory to the thread topic nor cost-effective just to (possibly) prevent another (what seems to now be) $10 cable issue yet another 6 years down the road. Thanks, though. :/
    Well it wasn't the power supply, nor apparently the SATA controller (I don't believe at this point). I finally got the hard drive to recognize and boot again, but ended up having to use one of the two extra SATA connector ports on the board (which I can only assume are handled by the onboard SATA controller as well) and a 4-pin molex to SATA power adapter connected to the power output for the secondary optical drive. As such, It very well may just be the "Hard Drive Harness Cable", although I need to order a male to female SATA extension cable so I can hook the drive up directly to the data side of that the drive bay connectors to determine whether it's the data side or the power side causing issues. I'm again assuming power, since the extra SATA ports seem to work, I'm pretty sure the drive isn't spinning up fully, yet the bays obviously 'recognize' there's a drive in there (thus the gray screen when one is plugged in).
    Anyway - I'll update when I get to that point, primarily for posterity's sake, as I found several "unresolved" gray screen threads on the web (and even in these forums) that sounded just like mine yet offered little ultimate help. In the meantime, does anyone want to speculate on whether it's the cable itself or maybe the SATA chain power plug on the board could be bad? It looks to be pretty close to the main power input connector on the board, so just wondering if (worst case scenario) something could have popped on the board between the two? Seems unlikely, but...
    Either way, I can always work around it all if necessary by utilizing the same setup I got it to boot with.

  • Not Recognizing External Hard Drive Mac Book Pro

    Good Day!
    I have a 2010 Mac Book Pro that I just downloaded the neww OS X Lion for the upgrades ext... I haven't had any other problems exept that before I downloaded the Lion my Mac would recognize my external hard drive (WD passport).  And now it doesn't, I even go to the finder and it doesn't even show up under "computer"  to make sure there isn't anything wrong with my external hard drive I plugged it into another mac that doesn't have Lion and it would work.  Please Help because my external drive has everything 1TG of everything...
    Thanks!!!

    Hi,
    I had already checked in Finder's Pref's for the check mark for External Disks and it is checked.  That is for external disks to show up on your desk top. 
    So still no luck for my Mac to reconize my external hard drive with this new OS X Lion Program.  Should I just take my computer into the apple store?
    Thank you!!

  • Windows 7 not recognizing my hard drive P67A-GD65?

    I installed an Windows 7 on a Crucial 300 SSD, and I also have a Western Digital 1 TB hard drive. The 1TB hard drive is in SATA slot 1, and the SSD is in SATA slot 8 (both of these are 6Gb/s slots). Windows only recognizes the SSD, despite the fact that my BIOS has both of them listed in the boot sequence. Any thoughts?

    if its new you have to go in drive management and set it up and format

  • IBook Not Detecting Internal Hard Drive

    So, this morning my computer started acting slowly, and apps started freezing. I restarted, and to my horror found that it wouldn't boot. It starts, and the screen is gray, but then nothing happens. I have discovered that the problem must be the iBook not detecting the hard drive. I booted into a linux live CD, and found that it could access the HD. Then when I turned my comp off, and went into select boot drive mode by holding option on startup, I found that no hard drives were listed to boot from. I have also tried connecting to my computer via firewire from another computer, and that couldn't detect it either. What is the problem here? I am becoming very nervous all my work is on there. Thanks for the help.

    Try booting from the Apple Restore disk and run the Apple Hardware Test that is on that disk. I fear that it may confirm a failure of your hard drive, but you never know until you try.
