LaCie 120Gb external hard drive no longer recognized

I've had a LaCie 120Gb external hard drive working independently off a firewire cable for a couple of months now. This morning it stopped being picked up as an external drive. It connects because you can feel it whirring, and stops when the computer is turned off (so the cables are working), but it no longer shows up in the finder or disk utility. I tried resetting the PRAM to no effect. Any ideas anyone???
Dave Nicholls, Auckland.

it spins because it has power. maybe your firewire port is damaged? does the drive have a usb port that you can try? if not, you can remove the hard drive from it's enclosure and install it in a tower mac or pc if you have one and see if it shows up then.

  • EXTERNAL HARD DRIVE NO LONGER RECOGNIZED, DOES NOT MOUNT

    Hello everyone, this is not necessarily a mac mini issue
    last night was working on my mac mini (intel 2007), it froze up, couldnt even restart, so i held the power button (hard reset i guess)
    it came back on but then would NOT recognize my external HD, (which is an iomega mini max 1TB)
    perhaps this was considered by my mac as "not ejecting or putting the disc away properly "
    i did a ton of research (here and elsewhere)..found various hints/fixes but nothing works so far
    i tried using different cables, firewire, usb..ran hardware test...zapped the pram....tried it on my ibook (which also does not recognize it)...turned the hd off and on...
    i unplugged everything, power to mac, all cables.. left overnight...tried again with no luck
    restarted, powered down...nothing
    tried finding the the external hd partitions in "/Volumes" to trash. there was ONE of the partitions there, which i trashed - no luck (i had 3 partitions on the external hd)
    was going to swap the hd to another enclosure, but the mini max hd wont fit it/work
    disk utility doesnt see it
    i tried a few things with terminal - nothing
    i am unable to open firmware (via commandoption+OF, as this is an intel)
    it doesnt seem to be a problem with the firewire port, as that port recognized my video camera
    im pretty sure the HD and my data is fine, its just that my mac doesnt recognize it. its like its already "on" or "mounted"
    it cant find the path or map or something like that
    in system profiler it comes up as:
    "Unknown Device:
    Manufacturer: Unknown
    Model: Unknown Device
    Maximum Speed: Up to 400 Mb/sec
    Connection Speed: Up to 400 Mb/sec"
    any ideas? why would force shutting down (by holding the power button) cause my mac to no longer recognize the external HD?
    i have NOT tried "discwarrior" or norton. trying to avoid having to pay $100 and i read that others with this problem bought discwarrior, which didnt see it or help
    i did try something called "total recall" by virtualab - it did NOT see the external HD
    and as i mentioned above, disk utility does not recognize it
    ok please let me know, i could really use some help here
    i do usually backup to dvd's but not everything..also did a ton of work recently that was NOT backed up
    hope to hear from you soon!!!
    thanks in advance, andrew

    hello, i dont have a UPS but have it connected to a power strip
    what might this mean?
    btw - when this first happened (3 days ago) i used disk utility/first aid to examine my mini, it PASSED
    yesterday i thought what the heck, ill run first aid again
    and this is what i got:
    verifying volume "mac mini"
    checking HFS plus volume
    checking extents overflow file
    checking catalog file
    incorrect block count for file AbletonTmp-0001
    (it should be 1 instead of 0)
    1%)
    checking multi-linked files
    checking catalog hierarchy
    checking extended attributes file
    checking volume bitmap
    checking volume bitmap
    or repair",0)
    checking volume information
    volume header needs minor repair
    the volume mac mini needs to be repaired
    error: the underlying task reported failure on exit
    1 HFS volume needs repair
    it wasnt able to fix it while booting/running off the mini so
    i then ran disk utility on the OSX install disc and was able to fix that problem
    but alas, no luck with the external HD, still not recognized
    the AbletonTmp-0001 makes sense because that was one of the programs i was running when it crashed
    i was hopeful that fixing that problem would help.
    ive been through quite a few crashes and restarts like that, i wonder why this time it caused such a serious problem
    i would imagine there are a ton of people who have to force a restart or dont eject the HD, or unplug it, etc
    i wonder why there isnt an easier/better way for a mac to deal with an external hd/flash etc. are pc's as sensitive with ex hd's?
    ive had to tell new mac owners again and again -"no! you have to eject it first!"
    ok well thanks in advance for any further advice/help
    it means a lot to me, so thank you!!

  • External Hard Drive No Longer Recognized

    Well, I've had this external for months...I've been backing up my files with Time Machine the whole time. It was time to back up again so I turned on the external, but now it does not come up or register with the computer at all. Disk Utility doesn't list the drive...I don't know why this would happen so suddenly, so I tried another USB cable but that didn't help either. Anybody come across this before?

    I'm beginning to think time machine is going to cause a lot of drive failures. My external Lacie had being spinning up every hour 24/7 since October 27, 2007 until this last week. That is over 10225 times just for time machine. That's not counting the times it spun up whenever I hit the save button. So at least 10300 times. Any way, I spent the last week trying to isolate the cause of my computer hangs thinking they were caused by the new OS 10.5.6 or the new Software I'd put in. I re and re'd the OS so many times, I had the installer verify the Leopard disc to make sure I hadn't worn it out. I even installed the OS on the Lacie and run the computer from there. it seemed to work fine and for a while I thought I had it beat. But no, not a chance. Last night, I was down at the local Apple dealer seriously considering a new Imac but they didn't have one in stock. This AM I thought I'd give it one more shot and it finally dawned on me that the Lacie wasn't spinning up the way it use to. I unplugged the Lacie and everything is now working just fine. Still kind of disappointed though. that new 24" Imac is one sweet machine.

  • Lacie Hard Drive no longer recognized

    I had the power go out in my apartment for a couple of seconds today and now one of my Lacie FW external hard drives won't be recognized or mounted by my Mac. In System Profiler, it recognizes it as "Unknown Device", but the Disk Utility won't "see" it at all. I also have Data Rescue II, but it won't recognize the drive either. I have 2 other Lacie externals that didn't seem to be affected by the outage.
    Troubleshooting I've already tried:
    - rebooting
    - shutting down, uplugging all drives, and unplugging Mac for 15 min
    - resetting PRAM
    Are there any other ideas out there? I've read good things about Disk Warrior, but I don't want to buy it if I'm not sure it will even recognize the drive. Thoughts?

    That was the kind of malfunction exhibited in some LaCie drives: They powered up, spun, but were unable to mount. Sometimes, the blue ligt on the front was barely dimmed or slighty pulsated along with the spinning. And usually, the cause of the problem was a bad AC adapter.
    Just Google for that info, or have a look at this page.
    If one of the other power supplies matches, you loose nothing but a copule of minutes by trying. If it doesn't work, the internal bridge board could be fried.
    It could also be a corrupt firmware issue, but if System Profiler is unable to identify it, the LaCie firmware updater will probably fail as well.

  • LR 5 my external hard drive no longer appears as a hard drive but as a folder under "Volumes"

    I am running LR 5 on a MacBook pro and my external hard drive no longer appears as a hard drive but as a folder under "Volumes". will this affect my ability to search and store in this external hard drive?  How can I get it back to normal?

    I just started having the same problem, oddly enough with a LaCie 500GB D2 Quadra external. Had it connected via FW800 then suddenly it won't appear in the Finder.
    It shows up as an "Unknown Device" in the System Profiler under the FireWire Bus.
    I do need the data on it so which solution is easier?
    Replace the housing? Or am I better off calling LaCie and using the warrenty?
    Thanks,
    Shannon

  • I have a MacBook Pro, 10.10.2 Yosemite. My external hard drive no longer appears on my screen or in Time Machine

    I have a MacBook Pro, 10.10.2 Yosemite. My external hard drive no longer appears on my screen or in Time Machine. I have gone into Disc Utility to repair disc, and get the message: Error: Partition map check failed because no slices were found. I was trying to follow Melophage's instructions by going into "Terminal" and entering  "diskutil list; diskutil cs list; mount"  and "diskutil info disk2."  Then I entered the command "sudo got show disk1."   I am sure I have made the problem worse. Can you give me some help?  Thank you. blelambert

  • 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.

  • External Hard Drive no longer showing in Devices

    My external hard drive no longer shows up as a device on my MBP. It has worked fine since the day I plugged it in.
    The Time Machine is using the HD, and continues to do it's backups, so power and USB connection is not an issue
    The HD shows up in Disk Utility (The Time Machine portion AND the partition that I've been using for storage)
    I ran a repair on the partition in Disk Utility and it checks out OK
    I can access this partition from VMware Fusion, so the windows side of the MBP sees it, and it's operational
    Used the HD all day yesterday without issue
    I've restarted the MBP to see if it would find the HD partition after a restart, it doesn't
    I've unplugged (USB) and powered-off the HD, and when I power-on, it still isn't seen.
    Any ideas?

    If TM is turned on and it still doesn't show up then do a SMC reset.
    SMC RESET

    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.

  • LaCie 1TB external hard drive can not connect to E4200

    I have my LaCie 1TB external hard drive plugged into the USB-port of the Linksys E4200 so I can access that drive wireless.
    However, in my disk management (via Cisco Connect), it does not show under Storage > Disk.
    How can I solve this so I can access this hard drive from any computer in the network?
    The drive is formatted in NTFS.
    Thanks

    Connect the hard drive directly to the computer and make sure that your computer can detect the hard drive.
    If it is detected and working properly on your computer then connect the hard drive the USB port on the router.

  • WD Passport External Hard Drive Not Being Recognized on PowerBook G4

    I bought a WD Passport 320GB USB 2.0 powered external hard drive that isnt recognized by my PowerBook G4. The funny thing is that the external HDD works perfectly on my friends MacBook! What's the deal with that?
    I called AppleCare but they just told me to take it into my nearest Apple Store... LAME!
    Can anyone else help?
    Message was edited by: WRDinc

    I had the same problem. See below for the answer from WD (...sigh...):
    Cause:
    Many 15" and 17" Macintosh PowerBook and Mac Book Pro Laptops do not provide enough power through a single USB port for the WD Passport™ external USB hard drive to work correctly. The WD Passport™ external USB hard drive requires a minimum of 1000Ma (Milliamps) of power for proper usage.
    Resolution:
    You can purchase a WD Passport™ Power Supply or a USB 2.0 Power Booster Cable from links below to the Western Digital Online Store.

  • Lacie d2 external hard drive

    connected lacie d2 external hard drive triple extreme to mini. Does not show on desktop. Does not show name in system profiler but recognizes a firewire attachment. Do not know what to do next.

    Disconnect the drive, then reset the mini's PMU. Once done, reconnect the drive and switch it on.
    If that doesn't work, check the connecting cable to make sure it's not damaged, and replace it if there is any doubt.
    To reset the PMU:
    - Unplug all cables from the computer, including the power cord.
    - Wait 10 seconds.
    - Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
    - Let go of the power button.
    - Press the power button once more to start up your Mac mini.

  • Installed 10.4.6 now ipod and lacie external hard drive no longer register

    Hi
    thankyou in advance, I updated to 10.4.6 but now the ipod and lacie external hard drive (usb drive) are not recognized by the computer. have tried disk utility, restarting etc but no difference. The lacie is recognized by another computer so it is not faulty. Any suggestions please?

    after reading this and resetting the PMU, my drive works. I'd say try it, the worst that could happen is you have to fix your time and date.

  • HT201250 my external hard drive no longer shows up

    I use a LaCie external hardrive for my Time Machine backup on my iMac..  Since October 24th 2012, my Imac no longer recognizes my LaCie..., and in fact no external hard drive is recognized.  When I open up Time Machine it asks me to set up another Time Capsule.??  Has somethingchanged either in the operating system [OS X 10.7.5] or with iCloud that would be affecting this?  My La Cie turns on and sounds like its working, and I have checked the power supply.

    Hi baltwo and Miacc,
    I also have a LaCie ext HD of 1T and OS 10.7.5. Since Dec 24th 2012 I haven't been able to mount the LaCie disk. I can see it in the Disk Utility but I cannot mounted. I verified the disk and even repaired it but nothing has happened, actually there is nothing wrong with the disk, but it cannot be mounted.
    I did what you suggested baltwo but I'm in the same situation as before. I cannot mount the disk and/or do Time Machine.
    Any suggestions?
