Windows 7: SSD + secondary hdd failure.

Hello,I am using a corsair force gt and a secondary ide hdd on a intel dp35dp mobo. At first everything looked just fine,everything was working as intend. Suddenly , computer i get computer freeze from time to time and i can't find the problem here. Bios is set to AHCI , using the intel RST drivers now but problem is still here.Could it be because of ahci setting and the ide hdd ? Before the freezing the HDD stops spining,i can hear him shutting down. Sleep time set to never in power options but that doesn't help,the hdd will 'sleep' even if i have a movie runing on it for example. The freeze looks random to me,it freezes everything ( mouse ,ctrl+alt+del ) etc and i need to reset my pc. Any tips on where and what to look for ?

It's physically an IDE HDD? (Ribbon, not sata connection)

By rights setting the BIOS to AHCI should have made that drive invisible from the get go

But if everything was working fine (same config, same BIOS settings and RST drivers) and it suddenly started playing up - it could be the SSD itself.

But if the HDD is 'going to sleep' while in use - that drive itself could be failing.

Thanks for quick reply. Secondary is on ribbon yes, drive is visible tho,AHCI enabled ofc. SSD is new.5 days,and the freeze only happens when secondary is in use and it shuts off(i can hear it shutting down).

I'm thinking a power problem. Particularly if the hard drive shuts down when in use.

Try using a different Molex connector. Preferably one from a different "tree branch" from the power supply.
Also try unplugging any non-critical 12v devices on the motherboard and test.

If the power supply is as old as that IDE hard drive it could be in it's last days, and adding the SSD pushed it over the edge.

Navigate to Control Panel\All Control Panel Items\Power Options\Edit Plan Settings and check advanced setting for HDD is set to never turn off.
