I/O Magic external drive not showing up in computer

Yesterday, I unplugged my USB connected External Hard Drive (I/O Magic Databank 200GB) & took it with me to work. In the evening, I came home & tried to connect it back to my home computer & for some odd reason, the drive no longer shows up (use to show up as F:). IN device manager, it says "Uknown device" in the USB area, also in Disk Management, it doesnt show anything...not even the volume. I just see my C: drive. I rebooted the server a couple of time, and at one time I did see the USB port in Device Manager as saying "Mass Storage", but now again it just says Uknown Device. The drive has important data. Could it be that I left the drive in the car for the entire day & the weather was quite cold??? As you say that the drive needs warming up.. The I/O magic site does not have any Drivers either. I have Windows XP, you cant contact me directly at

    I have been using my GigaBank 250 with no problem. I have a similar situation but I just unplugged my storage device from my older computer which was Windows XP to Windows Vista and it did not recognize it. Then I tried to hook it back up to windows XP and still nothing. Any Suggestions?

Had the same problem with the 120GM IOMagic. I removed the drive from the case, detached the circuit board leaving just the Hard drive and hooked it up to a cable I bought that allows you to read any hard drive through the USB post. Was able to retrieve all the data on the disk. The problem was the iomagic interface board.

Extreme temperatures, either very hot or very cold, can certainly cause damage to your External Hard Drive.  Based upon your description, it sounds like the hard drive enclosure has been damaged.  This would explain why device manager can not recognize it.  Your hard drive is plug-and-play with Windows XP, so no drivers are necessary.  Have you tried plugging it into another computer?
If your hard drive casing has malfunctioned, then retrieving your data is as simple as putting the hard drive inside another hard drive enclosure.  Hard drive enclosures are available at any local computer store, and also available on the I/O Magic website.  Make sure to get the right size enclosure.  Your hard drive has a 3.5" hard drive inside it, which is a standard desktop hard drive.

If you put your hard drive in another enclosure and it still isn't recognized by multiple computers, then the hard drive inside the casing has probably been damaged, and I would recommend contacting a data recovery specialist.

Have a nice day,

The item "IMB_0541.MOV" could not be moved because "TOSHIBA EXT" cannot be modified.

There are several possible causes for this symptom. It's possible that the external hard drive isn't getting enough power. Make sure that it's power adapter is connected correctly and working. If it's powered through USB only, try connecting it to another USB port on your computer (avoid plugging it into USB hubs and using long and thin USB cables).

Unplug the hard drive completely for at least 10 seconds, power off your computer in the mean while, power it on again (not a direct restart) and see if it resolves the issue.

Try to connect the drive to another computer and see if the issue persists. If the drive has the same issue on several computers, there might be a severe problem with the drive. If that's the case, start shopping for a new external drive. There's a chance for simple data retrieval though. If it's the electronics in the enclosure, the actual hard disc drive is probably still fine. If that's the case, you can find a way to open the enclosure (do a Google search with the precise model name and you'll probably find a tutorial) and you can install the hard drive in a desktop computer, a hard-drive docking station or another enclosure. Try to find a computer-savvy cousin/nephew to help you with this.

If it still has a valid warranty, exercise the warranty to get a free replacement.

Otherwise, open the enclosure, and separate the disk-drive from the USB-to-disk-drive adapter, and connect the disk-drive as a 'slave' disk-drive in a desktop computer, to see if the adapter was the problem.

My computer wont recognize my external hard drve and the io magic light is blinking

Try connecting the external hard-drive to a different computer. If it still fails, and it is still under warranty, then exercise the warranty to get it replaced.

If the warranty has expired, open the case, and remove the disk-drive, disconnecting it from the USB-to-disk-drive adapter.

Connect the disk-drive as a "slave" disk-drive in some desktop computer, to see if the disk is recognized.
If it is, then the USB-to-disk-drive adapter has failed, and you could go to any computer-store to buy a new external case and adapter, and mount your disk-drive inside the new case, and work with your files.

If the disk-drive is not recognized, check the warranty on the disk-drive itself.

Drive manager is grey and says that no drive is attatched.

You need to get a Seagate Harddisk Utility software to check the disk intergrity.

Although hardware issues like can sometimes be very difficult to fix due to the impact on a volatile component on the harddisk which are most times not replaceable

External hdd not detected

Formatting a drive means resetting it to manufacturer settings
And deleting everything in there, this solves most of hard
Disk problems, mp3s ipods ect..

if its powering on without being connected to anything do the following.

connect it via usb cable to your pc, or if it’s a hard drive its already connected.
click on start, right click on my computer and go to manage
in the table select, "storage" then "disk management"
in that table find the drive that relates to your mp3 player
if its not there "buy a new mp3 this is faulty" if its there
then right click on it and select "new partition"
you just next next everything and then format it and after
a while it shows "healthy2
unplug it, plug it back on and that's it your drive is fully working
now move what ever you want to it just like before.
