So I had 3 mechanical HDD's (all different), and 2 SSD's (one old, one new-ish)
2015 - 2 weeks ago - Homebuilt system works fine.
8-10 days ago - Multiple power outages during last few days.
6-7 days ago - Windows froze on boot, found out 4TB drive was the issue. Unplug it.
5 days ago - Windows freezing on boot again, now my 3TB and old 320GB drive are causing it.
3 days ago - Decide my 3 mechanical HDD's are fried but SSD's are ok. Notice my PSU fan is rattling but otherwise ok.
So I buy a new SSD, and a new PSU (probably not necessary), and a usb HDD docking station. I install the new PSU. I set up the docking station and use it to pull data from HDD's, to my working SSD's.
2 days ago - Windows showing errors for basic tasks like trying to get into device manager.
Yesterday - Reinstall windows on new SSD.
Set up a big overnight copy of some data from the 4TB drive, to my oldest SSD
Today - See the copy didn't finish this morning, with an error, but that's no shock, if the drive is dying. But now, my 2nd-newest SSD is just gone from windows and disk manager. I thought my SSD's were ok but apparently not. I haven't checked to see if it shows in BIOS yet.
So here's my questions:
• Research suggests this could be caused by a bad power surge. I have a basic $60 Staples UPS with battery backup, is this still likely?
• Is there anything else it could be? Is there a virus that just kills hard drives, or maybe a virus that works them to death? I hestitate to scan them because they're dying and not fully readable anyway. My realtime protection (Avira) never popped up any warnings this whole time though.
• Should I just replace the whole computer? Or at least the motherboard? Can my hard disk controller somehow get fried and cause drives to die?
