I have an external hard disk which got corrupted. When i connect the disk through USB it shows as an unknown device in the disk management with no option to format.

In My computer the device is showing as H: drive but unable to access it. It asks if i want to format or not but when i go for format it does not do it. I want to erase the disk completely as of now. What should i do??

I tried to load it from linux but there it shows as Device Error. Disk Failure is Imminent.

Can something be done or is it a hardware failure.

Sounds like the drive is failing or the circuitry in the enclosure is faulty.

I would first remove the drive from the enclosure and hook it up as a slave to a desktop PC. See if you can then access it. If you can, then post back for further instructions with the version of your OS.

Ok, use the hard drive diagnostics from the manufacturer as detailed below, but this will not give a true diagnosis while the drive is in an enclosure as it may be the enclosure that is faulty.

You need to take the drive out of the enclosure as I suggested so that you can eliminate the enclosure as the cause.

I have no idea what you mean by this:
i had windows 7 installed in that drive and connected to laptop hard drive
Identify the make of your hard drive and then use one of the links below to get the manufacturer's diagnostics for ISO (CD) not the one for Windows.
When the download is complete right click the file and select Extract Here and burn the image to a CD.
In Windows 7 right click the extracted file, select Open With, then select Windows Disc Image Burning Tool then follow the prompts. For all other versions of windows (if you do not have an ISO burner) download this free software. isoimageburner
Boot the PC into the Bios setup and set the CD/DVD drive to 1st in the boot sequence. Insert the disk in the drive then reboot and the disc will load into dos.
Excelstore
Hitachi/IBM
Samsung
Seagate, Maxtor & Quantum
Western Digital
Toshiba/Fujitsu
If you have a Toshiba/Fujitsu hard drive I would suggest the use of the diagnostics from the Seagate link as this will work on all makes of drive and on any OS.
