Is it a SAMSUNG HD204UI drive? I found a story about a bug
which makes the drive sometimes forget to write a block when it is
attached to a SATA adapter in AHCI mode and when the ATA command
"IDENTIFY DEVICE" is sent (like in hdparm -I or when using the
smartmontools).
Here's a link, but it's German only:
