[SOLVED] Hard Drives Disappearing

[yourmanG]

Hi! I'm new around here and i have an issue, i'm not that good at this kind of stuff either, i'm more of that kind of guy that plays video games only and doesn't even know what's happening inside his computer but...
I've been having this issue for a while.
I'm running Windows 7 Pro and my hard disks keep disappearing..
I had like 6-7 and now i'm down to 3. I had some games and other stuff on 2 of them and it takes A LOT to re-install them because i'm on vacation to my grandparents and the internet connection here is really bad.
Back to the actual thing, i had a lot of disks like C, D, E, F, H and I, from what i remember. And i had this issue for a LONG while and i'm still having it.
Also if you can help me:
The hard disks that disappeared don't appear in "Disk Management" and i have it so the hard disks never turn off in the Power Options. I've been looking for weeks and still didn't find a fix on any kind of forums and i tought that making a post myself would help .

By the way, have an awesome day!

agree your full system specs will be appreciated, tempted to say check the power and data cables however when drives re-connect you should not have to re-format, the data should be intact.

I think you should check your system logs for any "disk" errors (not just chkdsk as shown in the link).

If it were mine, I would:

• swap data cables and PSU (since I have a couple of spares) just to rule that out
• make sure your PSU can handle your devices (PSU calc)
• swap the drives into another system to test stability, and conversely try spare drives in the system
• use bootable linux to check stability, just to rule out windows problems

It is possible your southbridge is on its way out, I have a board that overheated and all HDDs connected are detected strangely and just have garbage characters in the BIOS where the model should be listed. Boots USB just fine

Hi! I did try the suggestions and it did work for a while until i restarted the computer.
I actually did something to fix it for now i think.
I removed the hard disk drives and put them back and it somehow made it work, thanks a lot for helping though!
