Hello guys, can I use an external hard disk as my primary hard disk on my PC because my pc won’t turn on when the power cable is connected to the primary hard drive. Thanks in advance for your advice.

Go into the BIOS and disallow booting from USB devices. It should work fine if the primary boot drive is a higher priority. Otherwise some things to try to make sure that the hard drive is completely dead and it’s not some other issue: Make sure you plugged in the appropriate cables to the hard drive.Try a different cable.Try putting this hard drive into a different computer and see if you still get problems. If you try all of those things and you can’t get fix the issue, then it is dead as a doornail and you will need to try data recovery to access the data within.
