I just had to "upgrade" a computer the hdd was making clanking noises and was dying. after backing up the hdd then imaging it to the ssd I found out it was set to ide mode.. to change it to ahci you have to (good idea for any sata hdd really)
Before and after benchmark using samsung magician 4 final notes: no other hdd makes a clanking noise quite like the ibm/hitachi deathstar. Computer was a AMD Phenom [email protected],8gb ram
The following technique can be used to switch between IDE-mode and AHCI-mode (the native mode for SATA) drivers in Vista or Windows 7: 1) Run the Registry Editor (regedit.exe) 2) Navigate to Registry Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci 3) Set the "Start" value to 0 (zero) 4) Navigate to Registry Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Pciide 5) Set the "Start" value to 0 (zero) 6) Shut down 7) Start up again, but before Windows boots go into the BIOS configuration screens and change the disk mode to "AHCI". Save the new BIOS configuration and restart so that Windows boots. When Windows starts, it will detect the change, load new disk drivers, and do one more reboot to start up with them.
