IC35L Deskstar not starting, can't see / find in windows explorer

you just transfered a copy of windows not the acctual os, install wondows on your new h/d then copy your files

The short answer is the drive is having trouble calibrating itself, and should be sent back under warranty for replacement.
There are things you could try to recover the unit, but why risk voiding the warranty only to wind up with a questionable drive afterward?

If you have the EIDE cables on your PC, it is easy. Your drives need to have their jumpers in the CBL SEL (cable select) positions (identified on the case on the sticker) and then you simply connect your Deskstar to the Master connector, and your other drive to the Slave connector.

You may have to up the power supply wattage to cover all the extra load you have with all the drives you have

try uninstalling a few unnecessary programs then click start run type cmd then type chkdsk/r/f which will scan for and attempt to fix any bad sectors and automatically fix any corrupt files on your hard drive then defragment your hard drive
hope this helps

Narros it down to the hard drive being dead.

This is typically a corrupt mass storage driver in windows. You can try removing C:\windows\driver cache (may be c:\windows\system32\drivercache too.

Then reboot; and see how it works. This resolves most of of the issues. http://techrxgb.com (please join us on facebook for hints / tips and tricks)
