I checked the computer with an other hard disk it works fine and I checked the first hard disk with an other computer it does not work so pls help me. Thanks
Well it seem like the hard drive is the one that is faulty then, but to be sure you can use DLG to run a test.
Hi if bios wont find the drive you wont beable to test it. Also if the drive came with your Dell it would be under warranty from Dell for one year. If it was a add on drive it would have full warranty. You can go here and check and see if it is in warranty http://support.wdc.com/warranty/index_end.asp?lang=en if so you can start the RMA process there also.
What do you mean by “it does not work”? Does the drive spin? Does the computer power up?
