HDD disappearing

[Metaljaw]

A few weeks back my 1tb western digital hdd started disappearing from my "computer" I could not explore it or access it at all, and it wasn't just the icon disappearing its not in my device manager either. After it originally started happening about a week later my power supply died, so i figured it was the last on the line for sata power and wasn't getting the power, i bought a new power supply (cooler master 650w gx) installed it and booted up and my hdd was fine for about 2 weeks, suddenly tonight i started a defrag on my hdd (perfect disk 11) and my drive disappeared again. I thought maybe the connectors, but everything was fine, so i rebooted checked my bios its recognized in my sata 3 port, i boot up and can access and run the drive for about 10minutes. I don't believe this has anything to do with it but i recent did a windows update and after booting it did a "drive check" i believe or diagnostic or something checking the ntfs format of my drive.

Any ideas on why this might be happening, did i fry the drive running it with the dying power supply? (old supply was a 6 year old thermaltake 500w silent pure power)

anything that doesn't involve formating, the drive is about 75% full and id really rather not lose anything on it.

If you can get it to be seen, run the companies drive checker. Download it from the website of whoever made the drive.

Welcome to the forums!

Try changing cables.
Change SATA ports.
Check power management, Windows "turn off disk after" setting in Power Options

I ran the diagnostic on the drive and the quick run came up with no errors, when i run the full diagnostic, twice, and i BSoD both times. i tried switching cables same issue, when i changed sata ports and the drive wasn't recognized what so ever. and i haven't gotten the the power management, but when i format my drive i usually set a power management, so that nothing turns off, but unless there's advances settings, i haven't been able to chk the settings cause its BSoD before i went to work.

What is the blue screen error message?

Sounds like something is broken somewhere. Probably the drive, but might be the controller.

well now it seems like i cant get the BSoD which i guess is good, but the problem is its like every 2 weeks the it happens. So i guess i have to wait for it to happen again to get the code of the BSoD but luckily i backed everything up now so if it is the drive I can have it warranty replaced.
