Had 3 P5K Pros. Tried on the 404 bios they were delivered with then flashed to the 10xx latest one. Same issue on 2/3 boards - randomly loosing drives when set to AHCI/RAID on reboot cycles.
Google SATA Problem P5K or SATA disappear P5K and you'll get a host of other people having the same issue.
1 board I got appears to be ok 95% of the time, but dropped one drive twice (out of about 50 reboots) so sent that back too. From the sounds of it, about 70% of the boards have this issue but it isn't noticed unless you have over 3-4 SATA devices connected.
I think it's to do with the black/red headers. ASUS did something odd by making the black headers "slaves" to the red headers. There's some obscure mention of it in the manual.
Now using two Abit IP35's, no issues - rock solid stable.
