I posted it in first message. But I have a Corsair 550w power supply. Another question, when I backup my info, if original HD crashes. Can I use that HD as main HD, or how does that work?
I agree, the first step should be a image backup. You would back up to another drive. If the drive was blank, you could image to it (make it a mirror image and therefor bootable (swappable). But usually you would just deliver a uncompressed (if possible to save time) image file to it and use it to restore to a new drive if the present one failed. Compress if you don't have much space on the backup drive.
I prefer Macrium Reflect Free
. This uses intelligent sectoring so the backup drive does not need to be the same or larger size to backup. Just enough space to hold whatever space is currently occupied on your suspect drive.
I suspect LatiosXT
wants to know the model # as Corsair makes great to fair PSUs. I know that is what I was wondering.
Then test the HDD with Seatools for Windows
. Be prepared to jot down a 4 digit error code, if issued. I would have a flash drive plugged in to record the drive info, and SMART and Short DST results. This can be used for a warranty claim if still warrantied. If you have backed up and it offers to fix or you can try to fix a error reporting drive and it reports it is fixed, you should still replace the drive. There really is no fix, maybe just a short term patch.
If the drive passes then I would suspect some other cause.
