Hi guys. I have a very strange problem. Untli recently i had a very well working system
Asus p4C800 Deluxe
1GB Geil Memory
Asus V9900 128MB
2 WD 120JB PATA
2 WD 200B PATA (1internal and 1 external in an external enclosure)
1 Canopus DVStorm2 (Video editing) Card
CPU Intel 2,8 / 512
1 DVD Recorder Pioneer 108
1 DVD Player Pioneer 119

Everything was fine until i decidet to upgrade the CPU to 3,2 /1MB Prescott
and add a new Seagate SATA Drive 200GB.

At first the seagate drive was very slow, every time i tried to open it the computer hanged and probably needed restart. Finally after a week full of effort i RMA the seagate and got a new one.

Now the new seagate exist in my computer with the other disks but it is significanlty slower than my pata drives. The strange is that Sisoft Sandra reports 54MB/s on SATA Seagate and 44MB/s at most on the other drives (my 1394 external gave 19MB/sec).

Despite that the SATA Drive is very Slow. I copy 3GB from my external drive and needs 5-10 minutes. I copy the same file to a pata and it completes in 2minutes.

I have 2 HDDs and 2 CDROMS on Primary and Secondary Channels
1 HD on Pri Raid (Promise)
1 Sata on SATA1
1 External on 1394 of the board

What could be wrong? In Asus bios i have set (Enhanced mode-SATA-5sec in IDE Configuration) and where the promised is mentioned i have RAID enabled. When i set this option to IDE the drive is even slower (sometime the computer stops responding). The driver i am using is Fastrack 378ATA (says in control panel). I have tried the FASTrack SATA 378 Driver but then the results are very bad.

Please can you suggest me the correct settings in Bios and the correct Driver to use??
Thank you in Advance
