Now, USB External Hard Drive Not Recognized after 10.6.8 Update

My external Hard Drive is not recognized on start up.  I have to unplug it and plug it back in for it to be recognized.
All this since 10.6.8 updated today.
I'm a fool for updating the same day.
This has happened before and I always forget the bugs in the software when it first comes out.

Alright, I'm gonna go ahead and close this thread. I found out the solution to my issue. Turns out it was a problem with a system file I changed right before installing. The error only occurred on a restart... the required 10.6.1 reboot was the first reboot since the change, so thus it looked like the culprit.
If you want a more thorough explanation of my problem (highly HIGHLY doubt it's gonna help you guys out), check this thread --> http://forums.appleinsider.com/showpost.php?p=1480362&postcount=8
Sorry for the trouble!

  • External hard drive not recognized after time machine locked up

    I was backing up to an external hard drive (300GB Western Digital) and time machine locked up. I had to shut down the computer and restart. Now the external hard drive does not show up on the desktop?
    I can see it in disk utility but I am not able to mount or unmount the disk, I keep getting an error that the disk is in use. I tried to erase/reformat the disk and no luck.
    Any suggestions?
    Thanks for the help

    Do I need to boot from the install DVD?
    this is often the easiest and eliminates any "busy drive" problems. what's wrong with booting from the install DVD? takes a couple of minutes.
    My main hard drive is OK... the drive that I am having problems with is an external hard drive that I was using to back up my lap top. I just want to get the external drive reformatted, but disk utility will not erase it. I get an error that disk utility shut down, "please check the drive and make sure that the drive is not in use or programs are still running"
    Is their a way to do a hard or forced reformatting of an external hard drive, I don't care about the information on the drive
    I also tried disk warrior to recover the info on the disk and all it does is crash my mac pro????
    Thanks again for the help

  • Lacie External Hard Drive Not Recognized After It Previously Was

    I have a 1 Tb Lacie Big Disk External Hard Drive that I have used for a couple years now.  I have a Mac Pro, an iMac and a G5 computer that I have previously used with it.  After I transferred it between computers yesterday suddenly it will not show up on any of the computers.  I have tried different cables and inputs, computers, other hard drives with the same cables (they worked), restarting the computers, etc.  The hard drives powers on like normal and you can hear it running, the blue light comes on in the front, but it never gets the disk loaded on the computer.  There is a "auto/on/off" button on the back that I have tried switching between but nothing seems to work.  Please let me know if this is a common problem and any way to get it to work as I would prefer not to lose the information on the hard drive, especially when it seems to be functioning just fine aside from not appearing on the computer.

    Even backups need backups too.
    And a 'good' case is one where you can pulll the drive out and pop it into your Mac pro drive bay.
    power supply bricks are known issue.
    Mac OS updates that affect those models.
    LaCie almost by their own invented the term and idea "reset firewire bus" routine after all.
    Years and you can assume not forever but eventually it could and will fail.
    I'd pick up a "spare" or replacement unit, one with eSATA/FW800/USB3

    CallDigit 2 x SATA plus 2 x USB3 $139 - USB3 card and interface works better even on legacy (how long and old is USB2 now?) USB drives.

  • WD external hard drive not recognized after improper eject

    I have a WD Passport external hard drive that I've been using for a while with my MacBook Pro. The cord got yanked, causing the drive to improperly eject. Now my computer isn't recognizing the HD. Help! Of course EVERYTHING important is on this drive!
    I tried plugging it into a Mac desktop, which also did not recognize the drive.
    I plugged a different Passport into my MacBook Pro, and it was recognized, so I know it's not the USB Port that's causing the problem.
    I used the cord from the HD that mounted with the problem HD. Didn't mount with the new cord. So I know it's the passport that's causing the problem, not the MacBook, not the USB port, not the cord.
    I ran the disk utility, and the HD does not appear...It is powering up though- the light on the HD is lighting up. Oh please help!
    Did I kill my disk? Of course I just moved my entire iPhoto library to this location, and I haven't backed it up yet....

    No.  It may just require a 00 Phillips driver depending upon the enclosure.  Do the swap on a towel so that the little screws don't bounce away from you.  You will have to pull the HDD out from the connecting plug.  Do it in a straight line,don't bend it, and you may have to slowly increase pressure to get it out of the connecting plug.
    It's not rocket science.
    Ciao.

  • External hard drive not recognized after power outage

    After a power outage last night my WD external hard drive is not showing up. The power light is on on the drive, the DVR is working normally, except my external drive is not showing up.  I unplugged power from the DVR and restarted it, but no change.

    I have a 2G Samsung drive in Rosewell external encloser running for over a year.  Two times have lost power and DVR would not recongize external drive.  The procedure I used was to reboot twice via menu>settings>customer support>in home agent>reboot STB.   Mine required two resets, the first reboot looks like DVR recongizes drive but does show as available but second reboot shows disc activity during last part boot up of box then external would show with all recordings and normal operation.   I have not lost any recordings.

  • External hard drive not recognized after OSX Mavericks

    My Toshiba external hard drive worked flawlessly before I upgraded to Mavericks, but now I cant access the disk. It doesnt show up on the desktop but it does show in disk utility. What do I do?!

    This isn't my question, but I'm having the same problem (with a Western Digital) and thought I'd share a screenshot of disk utility for comparative purposes.
    Also, Mavericks isn't allowing me to access Bootcamp

  • USB external hard drive not recognized by computer - using WRTSL54GS

    Hi,  I have my router (WRTSL54GS) set up and seems to be working ok, but the computer does not recognize it in my network.  It only recognizes it as a wireless connection.  Also, the USB hard drive I have attached to the router is not recognized anywhere on my computer.  What am I doing wrong?  Any help would be appreciated!

    hi - thanks for responding!  I have comcast and have their modem.  I hooked up the router with my laptop and went through the setup fine.  Everything with that works ok.  The USB drive is recognized on the web based utility program that you use to set up the router.  However, no where on my computer can I find the USB drive or where to even set up that driver.  The manual says that my router should be listed as a another computer in my network neighborhood and that I should be able to find the hard drive through that.  It is not.  Its only listed in my wireless connections.  I talked to a rep at linksys for awhile.  In the end, they just suggested unplugging it and plugging it back in......that didn't work!  Does that help? 

  • External Hard driver not recognized after force eject while Mac was asleep

    So my Samsung hard driver had force ejected itself when my Macbook pro was asleep, it cant be recognized anymore. It doesn't show up under utilities, however it does show up under System report.
    I've tried to plug it onto my desktop, however the system had failed to install the software to run the hard drive, yet again it does show up under properties.
    Help please???!!!

  • External Hard drive not reading after 10.3.9 update

    Hi there and thank you for this forum. I am wondering if anyone can help me through this maze of confusion...I have just recently upgraded from 10.3.5 to 10.3.9 and now I cannot access my external Fantom Drive. Both of the USB ports can read other devices, and also I can still read the Fantom from a PC, but when I plug it into my ibook, I get nothing.
    Can anyone recommend anything? Can I reinstall the original 10.3.5 software and be done with updates? The Fantom is not supposed to be affected by the 10.3.9 system, so I don't know what happened, but I can tell you that the only 2 times I have updated this mac, I have had serious problems! I won't be updating anymore!!!
    Thanks mates...

    You're welcome.....and thanks for acknowledging me in your post....
    I'm sure you would have thought of this workaround sooner or later....After 2 reinstalls of OSX this was my last resort.

  • External hard drive not recognized... help please.

    okay, well here is the story:
    my iBook G4 had its stock 30gb hard drive in it and it was running extremely low on space. so i figured i didn't want to carry around an external hard drive, therefore i would buy an internal hard drive an install it. so i purchased a new 2.5" 80gb hard drive and called up the local apple store. they told me that although it was under warranty, that it did not cover hard drive installation. so i looked it up online and found step by step instructions to install the hard drive. so after lots of hard work and many screws, i installed the new hard drive successfully... but i still had this perfect 30gb hard drive. i thought maybe to save a few bucks i could turn it into a usb external hard drive. i found an enclosure for the hard drive and a usb 2.0 cable and plugged it into my ibook. it was recognized and everything. i put some files on the external hard drive and transferred it to another mac. this is where the trouble started. i plugged the hard drive into a PowerMac G4, and it was not recognized... so i tried it on a different mac. this time on a PowerBook G4, but no luck. this issue has been troubling me for a few weeks. but then i tried it on a similar iBook G4... and it was recognized. but i don't know why it was only recognized only on the iBook G4 (not the same iBook G4 it was pulled out of) and no other macs.
    does anybody have any ideas what we can do to get this hard drive to be recognized by other macs?
    any of even the smallest ideas would be greatly appreciated.
    thanks,

    I can walk you through formatting the hard drive:
    1. Hook it up to an iBook that recognizes it.
    2. Go into your Applications folder, then scroll down to Utilities. Open Utilities and scroll down a bit and you should see Disk Utility. Double-click.
    3. On the left side you should see your internal hard drive and your external one. Each hard drive will have a sub-catagory with the partition indented.
    4. Your external hard drive will probably be the second catagory. Click it.
    5. In the center-top you should see the tabs First Aid, Erase, Partition, RAID, and Restore. Click the Erase tab.
    6. You should see Volume Format: and then a drop down menu, and Name: and a text box. Type in the name you want the external hard drive to be named.
    7. In the drop down menu, select Mac OS Extended (Journaled).
    8. Then, simply click Erase, watch the progress and it should be good to go!!
    Hope I helped you out. Oh, and it might be the enclosure...and also what OS's? Since it's USB it is probably using a USB Mass Storage driver. Mac-wise, if formatting doesn't help, I would get a FireWire enclosure because FireWire is much faster than just USB 2.0. Oh, thats nother thing...Is the enclosure Hi-Speed USB? If it isn't, I would definitely get a FireWire one...If it is, the PowerMac G4 doesn't have Hi-Speed so you're not taking full advantage..Just some insight

  • Panther crashed now external hard drive not recognized

    I was away and a person that lives where I work on my computer set up his computer right next to my G4 iMac. When I looked at the screen it was trying to boot into start up mode but wasnt making it. I firgure it must have been caused by all the pluging and unpluggung.
    I tried the resart disk but still has problems, so I reinstalled 10.3.9 al over again. Now its working but it doesnt reognize my external Lacie hard drive.
    Ive tried restarting a cople of times, I cant firgure out what could be the trick.
    Has anyone any ideas?

    I don't know if the following will help with your issue , since it shows up in Safe Boot, but here it is.....
    External hard drive spontaneously unmounted? Try these tips:
    NEW FIRMWARE: Try updating your external hard drive's firmware, which is available from your drive manufacturers Web site--or just use VersionTracker's (www.versiontracker.com) search function to find it. Be sure to back up your data before applying the update, and carefully follow the manufacturers instructions.
    OUT OF iSIGHT: If you're using an iSight camera while you're using a FireWire drive, the camera may be interfering with the drive's ability to stay mounted. Try temporarily disconnecting your iSight and moving it to a separate FireWire port. If you have multiple FireWire devices, try using a FireWire hub.
    POWER PROBLEM: A faulty power adapter could be causing your drive to unmount. Your drive may not be getting enough juice to stay on, causing the drive to turn off and thereby unmounting it from your Mac. Alternately, the power adapter may not be providing a steady amount of power, causing your drive to turn on and off. Try replacing the adapter. If you can't get a replacement adapter from the hard drive manufacturer, try your local electronics store. Just make sure the adapter you choose has the same connector and input/output voltage. you can find the input/output voltage on the adapter itself.
    Cheers!

  • Toshiba External Hard Drive not recognized by computer. Please help!

    I was wondering if anyone could help me. I have an external hard drive and it will not show up in "My computer" when I plug it in. I have tried other USB drives and other computers. I am starting to think it is a hardware issue but I don't want to lose hope. The blue light is coming on when you plug it in but it doesn't blink and there is no noise whatsoever. Is there anything I can do to fix this issue so that I can recover the information on it? Thanks in advance for any help. It is greatly appreciated.
    Additional information: I'm not sure how old this thing is but the model number is HDDR160E03X.

    Same problem: I can't see my Toshiba PH3100U-EXB (Gen 2) external hard drive when I plug it in. After awhile I get this error message (see attachment): USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. FOr assistance in solving this problem, click this message."
    When I click it, I get a list of USB ports and devices, with Unknown Device in bold face. No real information there.
    Yes, I ran Disk Management and the Toshiba did not show up when I plugged it in and hit Refresh.
    Does it make a difference that the last time I used the external hard drive, we were in Windows XP and now we're in Windows 7?
    Please help! It's not just the backing up I'm worried about...it's being able to retrieve files later!
    Thanks!

  • External Hard Drive not recognized.

    Hello everyone,
    I have a probem where my external hard drive is not being recognized by my late 2009 iMac.
    The hard drive is an OWC Mercury Elite-AL Pro connected to the firewire port.
    It was working fine till this happenend:
    I keep all of my iTuned music on the external hard drive.
    I was using a meta tag fixer type program.
    I dragged the files from itunes into this program (Tune Up) to fix the meta tags.
    However, I missed the program and dragged thusands of .mp3 files onto my desktop.
    My computer, of course, became unresponsive.
    So I used the power button on the back of the iMac to shut it off.
    I used my MacBookPro to connect to my iMac as a target drive, and deleted all the .mp3's from the desktop there.
    Once I restarted my iMac everything was fine, except that the external hard drive has not been able to be recognised ever since.
    The same drive shows up just fine on my MacBookPro.
    Help!
    Thanks!

    I had the exact same problem! I had to force shut down my iMac (24in, Mid 2007) due to a system freeze. After restarting, everything was working fine, except for my external 1GB G-Drive, which was connected through FW800 port.
    The drive connected fine to my MacBook Pro, but it would not be recognized by my iMac. I tried restarting, but neither Disk Utility, nor System profiler would see the drive.
    What worked though, was Resetting the System Management Controller (SMC):
    1.          Shut down the computer.
    2.          Unplug the computer's power cord.
    3.          Wait fifteen seconds.
    4.          Attach the computer's power cord.
    5.          Wait five seconds, then press the power button to turn on the computer.
    The drive mounts fine now. I am surprised this is not mentioned by Apple in their support documents! It has happened twice to me and it was the only thing worked both times. The link for the resetting the SMC is here:

    Hope this helps solve your problem too.

  • External hard drive not recognized by Mavericks?

    I have a Western Digital My Passbook 500GB external hard drive connected to my MacBook Pro via USB. 
    It worked fine until I upgraded to Mavericks.  Now it is not recognized at all in my Finder.
    When I go to Disk Utility, it finds it and says "not supported".  When I do "disk verify" it says it needs to be repaired.
    When I try to repair it, it says it can not.
    What do I do?

  • External Hard Drive not recognised after horrible crash and reformat.

    There's yet another problem with my MBP.
    First of all this happened: http://discussions.apple.com/thread.jspa?threadID=969838&tstart=0
    Since I got it fixed I bought a 500GB Freecom external Hard-drive and used it to back up all my stuff. It was a case of plugging it into the USB port and it mounted on the desktop. I've had it for about a month.
    I've only just got my MBP back from getting the keyboard replaced, then on Saturday night it crashed. And kept crashing. Then it wouldn't boot. Then it crashed when booting. Then it took me to a command prompt. I reset all the parameters laid out in the troubleshooting guide. I managed to boot in safe mode, but my Freecom drive wouldn't mount anymore. But it kept crashing and crashing. I finally managed to boot from the installation CD and I reformatted the drive and installed OS X (Tiger) afresh. But now my Freecom drive won't show up on the desktop at all!
    I ran a Hard Ware test after the reformat, and the code 4MEM/2/40000000 came up, then again, 1FCA8574, then 41530574.
    When I had the Freecom plugged in it would show in System profiler but not mounted on the desktop.
    What is wrong? I am really annoyed because my Warranty ran out yesterday and I'm only after getting it back from Apple to get the keyboard replaced!
    Please help!
