Canvio 3.0 1TB Drive No longer shows up

I have a Toshiba Canvio 3.0 1TB External USB HD.  Today the drive disappeared in the explorer (no drive letter, etc).  The drive still appears in the device manager, however the Disk Management utility shows the drive is Not Initalized and when I attempt to initialize it, it fails due to an I/O device error.  I have the same problem using all USB ports and on another computer.  I uninstalled the drive from the device manager and reinstalled the drivers, all to no avail.  The light on the drive comes on and I hear the drive making noise but can't get to the data.  Do I have any recourse or is my data gone?

  • External hard drive no longer shows up connected

    I have been using a Seagate Freeagent 500 GB external HD as a backup storage device for my Windows 7, 64 bit computer. After working well for several years it did not respond the last time I tried to back up and shows up as "disconnected" when
    I search for the HD in device manager or control panel.  It was assigned Drive I but that drive no longer shows up under drives.  I have tried different USB ports without success. Oddly, the audible signal sounds when I remove the USB cable from
    a port but does not sound when I reinsert it.  I also tried powering down the hard drive and powering up again without success.

    Hi,
    If other PCs can show this external hard drive, You can try the following steps to clear the write-protected flag to see what's going on:
    Open a command with administrator privilege:
    type--> diskpart
    type--> list volume
    type--> select volume #
    type--> attributes disk clear readonly

  • 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?
    John

    If TM is turned on and it still doesn't show up then do a SMC reset.
    SMC RESET
    Shut down the computer.
    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.
    Release the keys.

  • Hard Drive No Longer Showing Up In My Computer

    I Purchased an HP Pavilion dv7-6188ca Entertainment Notebook PC back in December of 2011 and had no problems up until this point. I noticed today that my secondary internal hard drive is no longer working. It doesn't show up in My Computer any longer, nor the computer BIOS. I noticed a small dent to the right of the touchpad and was thinking that a family member may have dropped something on it. I want to know if there is anything that can be done to try and at least recover the data on it. Any suggestions would be helpful. I also checked in Administrative Tools and the drive doesn't show up there either.
    I'm running Windows 7 64 bit. I haven't done anything recently to change settings on the computer or anything either.

    I fixed it!
    You have to go into your Pictures folder and delete the iPhone Photo Cache folder....then it will recreate it and successfully sync!!
    It still does not show up in My Computer but I think if I reconnect my iPOD and enable Disk-Access, that that may resolve that small problem as well

  • External Hard drive no longer showing up

    Hi all,
    hope you can help.
    I have an external hard drive that I use as a TIme Machine Drive, the other day my wife decided I was wasting electricy by having the hard drive on, si se turned it off without ejecting it, thanks love.
    Now the Hard drive wont show up on the desk top, I've ched the system preferences ans that's set to show extrernal hard drives.
    Profiler shows the USB hard drive as there.
    Disk Utility shows the hard drive, Wrong name but the right serial number. but it wont let me repair, erase or partition.
    Suggestions on how to get this fixed would be epic, I'm guessing that my iMac just didn'y like it when the drive wasn't ejected correctly, I'm hoping there is away to sort the problem without replacing the drive.
    Thanks guys.
    Dave

  • I recently upgraded to Maverick 10.9.2 USB Hard Drive no longer shows

    I just upgraded to Maverick 10.9.2 and my external hardrive (Toshiba Canvio Basic 3.0 Portable Hard Drive, PN#HDTB210XK3BA) is no longer appearing on my desk top when I plug it in.  It shows in the Disk Utliity and I have tried doing a verify as well as a repair and I stilll get the same message...
    "Updating boot support partitions for the volume as required."
    I did a backup just prior to updating to Maverick so I know the external drive still works.  Plus I am able to see the files on my PC when I plug it in to there. 
    I did try resetting the SMC and the NVRAM/PRAM.
    I plugged other externa; drives in (Maxtor, Seagate, etc) and again they did not show on the desk top but did show in Disk Utlity.
    I see this has happened to several folks but am wondering how they got it fixed.

    You need the printer drivers for Mavericks.. have you loaded them?
    You can expect issues as lots of printers are not yet up to date with Mavericks.. if you can find drivers. delete all the previous printers and start over using the new drivers.

  • External hard drive no longer shows up on Desktop

    Hi everyone,
    I did what a good person should do with a tech issue and did a long search through forums before I resigned to bothering you all with it.
    I've had a 500GB Seagate FreeAgent GoFlex Media external hard drive for 6 months which up until this week, was showing up as an icon on my Desktop. I had named it Eid HD.
    I suddenly am unable to access this drive on my MacBook Pro. The Desktop icon has disappeared but the drive still lights up as per normal. I'm using OS X v10.6.8
    I tried changing USB cables.
    The drive appears in Disk Utility as follows (the yellow icons):
    I read somewhere that I needed to mount it. The first yellow icon doesn't have the mount option. The second one (Eid HD) has the option but when I mount it, I get the following message:
    Mount Failed.
    The disk “Eid HD” could not be mounted.
    Try running First Aid on the disk and then retry mounting.
    I verified and repaired (First Aid) the disk. Results:
    Tried to mount - same error message as above. Mount failed.
    I downloaded Disk Warrior and although the drive appears in there, I can't do anything with it. The Graph and Rebuild buttons are both greyed out.
    Does anyone have any ideas about how to fix this?
    The files are still on the drive as I used it on a Windows machine to test it.
    I don't want to format it.
    Please help if you can, thank you in advance.
    Sam

    I verified and repaired (First Aid) the disk. Results:
    That quote is from your first post.  But I have some questions about that (maybe just to satisfy my own curiosity).
    1.  When you ran Disk Utility First Aid did you do it on the disk itself (the one that is enabled with the Seagate title)?
    2. That First Aid window title line says "First Aid: EID HD" yet my DU window title only shows the name exactly as it appears in the left panel, no "First Aid:" prefix.  So is that a change in 10.6.8 (I use 10.6.5)?
    3. You display shows lines like "Verifying folders", "Folders verification completed", and "Verifying $...".  Again I have never seen DU display that kind of info.  Another 10.6.8 change?
    As I said, I am only curious.  It may not mean anything.  But I thought I would point out these details just in case.
    If these aren't 10.6.8 changes (I find it hard to believe apple would change DU after all these years just from 10.6.5 to 10.6.8) then just what DU First Aid were you running?

  • WD MyBook External Hard Drive No Longer Showing Up

    After the Yosemite update, I can no longer see my Western Digital MyBook external hard drive when I plug it into my MacBook. I've been up and back between Apple Support and the WD support forums for about three weeks now and I'm not seeing anything helpful about this situation. I cannot access a bunch of stuff because of this problem. No one is saying whether or not it will be addressed at all let alone supplying a solution... Does anyone have any info at all about this?

  • DVD drive no longer shows up

    I got a HP Pavilion g6-2392nr a few days ago and today I decided to create some recovery disks. This is Windows 8.1 I should mention. I created disks 1-5 but when I put a dvd in the drive for disk 6, it kept waiting for me to insert the disk. I tried another disk and it also could not find it. So I cancelled the creation of the recovery media and restarted. When I logged back into Windows I attempted to read another disk, just to make sure it was working, but the drive never appeared in the file manager, though I do hear it spinning up. After this I attached my usb dvd drive and tried to finish the final disk. This seemed to finish but then it told me to insert another disk. Anyway, when I look at the device manager the only driver I see is the usb DVD drive, but no drivers now seem to correspond to the integrated one in the laptop.
    Does anyone know why this might suddenly happen after hours of working fine? I am getting very frustrated because this is just another in a long line of problems I have been having since getting this computer.

    Okay, eventually I found a suggestion in one of the troubleshooting guides that indicated that I should remove the battery and power, shut down for 10 seconds and restart. This worked. What I want to know now is, why would this work, and should I still be concerned that there is a problem with the drive?

  • Canon i860 driver no longer shows in airport express

    I've been printing to a canon i860 via airport express without incident for a year now. I only do it when I travel on business, so it’s like twice a quarter. I’m out on a trip now and got everything setup only to find that in printer setup utility it was no longer listed as an available option. No biggie, I'll just re-add it. Bonjour sees it, I select it, but when it prompts me to “print using”, I select Canon but the i860 is not listed in the drop down list. It stops at S800 - Gimp- Print v5.0.0 beta 2. In fact, everything has the gimp print suffix after the printer name, whatever the heck that is. It used to list the I series printers so I could just select the i860, but no more. I select the s800 and it prints greyed out. I select the s400 and it prints black but on a third of the page.
    Help!

    I'm posting on this again as I'm still having the problem.
    I re-downloaded the appropriate driver from the Canon site and first added the printer via USB and that worked fine. Under “Print Using” it said Canon i860.
    Then I connected it to the airport extreme and it sees it but the auto select under ‘print using’ comes up blank and is making me select something, but under Canon, like I typed above a few months ago, I don’t have the option of selecting my printer. I don’t know if it’s possible to manually point it to the driver, but I have no idea where drivers are stored to even try.
    Anyone know what’s going on here? It used to work just fine. I used to just select the printer and away we went. Now it’s just not finding the driver.

  • WD Hard Drive no longer showing up, but it is running

    Hello all,
    I have a WD 3200MT external hard drive that I plug in through USB. It has always worked no matter what operating system I have upgraded to (Currently running Yosemite on my Macbook Pro 13in mid 2012).
    Today when I plugged it in I noticed that it made my trashcan full on my desktop. I figured it had something to do with all the stuff I have deleted off of the WD external drive. I "emptied trashcan" and it started emptying thousands of items. Some items were even running and it asked if I should skip them and continue. I let it go for a few minutes and then figured something wasn't right. I unplugged it (Just pulled it out) and now I can not get it to show back up when I plug it in. I can feel the external drive running and the lights are on, but nothing appears on my Macbook.
    My trashcan shows a "Recovered files" and "Recovered Files #1" folders. Can anyone help me out? I have tried searching all over.
    Thanks!

    After being plugged in for 30 minutes, this just popped up on my screen.

  • USB Flash Drive no longer shows on Desktop, it does appear in disk utility. I recently upgraded to 10.8 from 10.6 on both iMac and Macbook and the drive does the same on both.

    I updated my Snow Leopard to Mountain Lion and have had only minor issues with some software but I plugged in a USB flash drive and went to format it, it now appears only in disk utility and not on the desktop. I have tried restarting and reseting with the drive in and out, I tried it into my macbook and it does exactly the same there. I can't do anything in Disk Utility so can't access it in any way and it says errors if I try to eject it from DU. I'm not normally stumped but I can't figure this out at all. I'm hoping that someone here could give me an idea that I haven't thought of as it's a large Flash Drive and I really would like to keep using it.
    Thanks in advance for any help anyone can offer.

    If it has the same (bad) behavior on two different systems then there is a very good chance that the  drive is toast.
    BTW you'll get better response to your questions if the question actually reflects the problem you are having. In this case it would have been better to say you couldn't access the drive rather then that it doesn't show on the desktop.
    regards

  • External drives no longer show up - light is on but nobody home!

    Hey all,
    Still using an old iMac G4 and it works great... 10.2.8
    (and ibook 10.3.9)
    plugging in some Maxtor External drives and they don't show up (mount)
    I hear them. The light is on.
    Checking in disk utility shows that computer senses them and says I can repair permissions (have not tried that yet) but they never appear
    on the desktop. These drives are more than 5 years old and haven't been used in about a year - my mistake. use it or lose it apparently.
    If anyone can throw a life raft I'll grab it.
    thanks,
    Al

    Dale,
    They don't show up in Disk Util.
    Nothing to click on.
    When I plug them in I get a message saying do I want to initialize or ignore?
    I am assuming initialize would erase everything but there is stuff on them so I don't want to erase.
    thanks,
