Hello since first prerelease of BSD7 i got on disks atached to MCP55 SATA controler data corruption. One thing that is strange is that this controller works ok with 6.3 but not with 7.0 PRE, 7.0 STAB. or 7.1 PRE I tryed both schedulers without success. I got AMD64 X2 6000+ 6GB RAM and ATA and SATA 150 and 300 discs. Can anyone help ? A.
