SOURCE: Western Digital External HDD not appearing in My Computer

It could be that the OS is not assigning a drive letter to your removable drive. To do this, go to disk management and assign one.

Assuming OS is Win 2000/XP/Vista

Right-click My Computer then Manage
Click on Disk Management
Right-click the removable drive and click on Change Drive Letter
Assign a drive letter and click OK
Your drive should now show up on My Computer

Hope this helps.

SOURCE: Suddenly my Iomega 1tb stopped working and i

Have you tryed chkdsk in the command prompt, goto command prompt and type CHKDSK F: /F and press enter, this is a tool that checks your drives for any errors and hopfully should resolve any problems, rather than formating it and loosing everything on the drive.
Also have you tryed setting up the usb for mass storage in the bios somtimes there is a setting for this in the bios, or try setiing it back to factory defaults and see if that works.
The only other option would be to update your usb 2.0 driver in device manager in the properties of my computer icon on the desktop. hope this helps in some way and post back what happens.

SOURCE: i am getting the data error (cyclic redundancy


A cyclic redundancy check, known as a CRC error, often occurs when you're attempting to transfer data to a hard drive. It's most commonly caused by an interruption in the recording process, but also can be a sign that you've got problems with your hard drive or optical drive.

Here are some steps fixed the issue:

  • Rule out problems with your computer Start by defragmenting your disk. Click the "Windows or Start" button in the lower-left corner of your computer screen and select "Control Panel." Click the "System and Security" icon. Choose "Administrative Tools," then "Defragment your hard drive." This will clear up clutter on your hard drive that could be causing the error

  • Use the CHKDSK program in Windows to see if there are other problems with your hard drive. Click the Windows or Start button and select My Computer or Computer. Right-click the drive with the CRC error. Choose Properties, then select the "Tools" tab. Click Check Now. Make sure the program will fix disk errors by checking the top square in the dialog box. Click Start.

  • Thanks for using Fixya.

    Backup hdd to external hd

    DVD recorders are usually not the first selection for backup of data files. you may be better off with a 1 Tbyte external drive, which is suited for that purpose. Even though the DVD drive has the capacity, there are usually formatting issues with data files being burned to a DVD recorder.

    My external hard drive is not being seen by my computer?

    1 of 2 things can be wrong...1 (cable may be loose) unplug the cable (ext HD) connected to pc, now reinsert back into pc..try this once or twice...until you see it appear in my computer....if this is not working and your ext HD came with a CD software..uninstall (make sure ext HD is not connected) software, then reinstall make sure your firewall allows it to be connected....this should do the plug HD back up to not format your ext hd unless you really really dont want the data on it (format erases everything)

    Attach your external HD with some other computer, that will definitely appear normal, the problem is due to a virus in ur HD. Your computer's antivirus software stops it to appear. Back up your data on the other computer, format ur external HD, remove un-necessary files and run a virus scan to the files u copied from HD, Hope this will solve the problem, if not, let me know and tell me what would be the response on the other compuer

    Mac OS X 10.4.11 SimpleDrive 1TB HD appears on Desktop only occasionally. Does not appear in Disk Utility. Have transferred files to it, light is on, plugged in, just takes several restarts to appear.

    If you unplug the power and USB cables from the drive (but not the computer), plug in the power and then plug in the drive, the Mac will remount the drive on the desktop. I am having the same issue, only my old HDD used to be my TimeMachine drive and now I want my SimpleTech drive for that. The issue is that when the SimpleTech drive disappears, OS X automatically uses my old HDD for TimeMachine and all my disk space vanishes.

    Very ARRGH!!!

    I'm trying to find a better solution, because having to mess with the cables means it's no good for TimeMachine... and very frustrating on top of it.

    I cant detect my USB external HD for more than a minute.

    There is probably a fault within the hard drive, the circuitry of the housing or perhaps the usb lead.

    It would be as well to check the power supply first as some of them are less than reliable and are apt to provide too much voltage.

    I have an Archos 605, and have also purchased the console to connect it to my tv. This console has a USB connection, and the instructions say that I can connect my external HDD to it, and view this using...

    Here's what you do.
    Make sure that you can play one of the sample videos to your TV. Next, stop and go to the home screen.
    Next, if your external HD has a powersource, plug that into the wall and the device so that it has power. Next plug the usb cable into the side of the DVR Station. The device screen (or the tv if you are still on tv out) should say, external device connecting. It will show the double browser screen and then just go to the file desired and click on OK. If the device doesnt recgnize and mount the external hd, could be because there is not enough power to the ext. HD or the HD is formatted in somehting other than fat32.
