Internal drive stop'n'start

I recently drafted a platoon of app's from the DL page here & every now'n'again 1 of my internal drive's decides it's time to stop'n'start, then I'm frozen out.
Any1 know witch app could B the culprit?
Here's the list.

[Ledgend: * = Good I think.

Cybertweakfull (haven't used yet)
Cypherixle72
Dlaccel-whelp
Fci
KeyScrambler *
Lps *
Mbam *
Pginstall
Watchdog
Winvulscan (stand-alone, I think)
--------------------------------
These didn't want to sign-up at all & I'd really like them too.

Harden-it (Bad CRC)
Lockhunters (corrupt data)
Cane&Able (corrupt install)
nn29b (internal error B109-11)
