Windows 7: HDD Speed automatically reduced after crash?

HDD Speed automatically reduced after crash?

Hey guys

I had several crashes with skype and hibernate. Thats a known problem with newer than 5.0.0.156 versions.

My question - in the old xp and ide days windows slowed down the hdd after several hdd crashes automatically and on e had to add a registry key to stop xp doing that.

Is Windows 7 doing the same?

I am on a asus notebook and and Intel ICH9M-E/M SATA AHCI Controller

Windows slowed down the rpm of a drive... just because of a few crashes? Never heard of that happening. Got any links?

No, XP would drop the drive out of DMA into PIO mode after enough failures (mainly a problem when the disk didn't spin up within a timeout period).

If you want to find out, go to device manager - select your disk controller and find the channel your drive is on, select properties and advanced settings and see if it is in PIO mode instead of Ultra DMA mode

SATA drives operate differently, they don't change modes.

No, I had this happen to a SATA drive (under XP I believe). The OS dropped it down to PIO.
