HDD Problem/Fault

[Msm2]

Over the last few days my 500Gb HDD has started to disappear from "My Computer" then I get a bubble message such like "F/: unable to write to disk,data will be lost". If I restart PC the HDD is found. Im totally lost with this. Can anyone help.

Dropping in/out is often power related, if not a duff drive.

Change the power connector to another rail and see what happens.

Cheers Rasta will try that.

Install HDD health to see if the drive is failing
