hi there, when doing fsck on my / fs i get this error: "Cannot Read BLK. 471617640" and "The Following Disk Sectors could not be read: 471617643". after this message the partition gets marked dirty. i performed the following steps to verify the problem: 1) dd if=/dev/ada0 of=/dev/null bs=1m 2) fsck / under freebsd 7 3) mount -u -o snapshot /.snap/snapshot1 / && fsck_ffs /.snap/snapshot1 all three steps showed no problem with that harddrive whatsoever. also smartd doesn't complain about anything. i'm running HEAD (r205860) on amd64. this is the output of `dmesg -a|grep ada0`: ada0 at ahcich2 bus 0 scbus3 target 0 lun 0 ada0: <SAMSUNG SP2504C VT100-50> ATA-7 SATA 2.x device ada0: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada0: Command Queueing enabled ada0: 238474MB (488395055 512 byte sectors: 16H 63S/T 16383C) -- Alexander Best
