pozrel som do kernel logu a nasiel som toto:

Mar 18 16:11:16 [kernel] hdb: command error: status=0x51 { DriveReady
SeekComplete Error }
                - Last output repeated 50 times -
Mar 18 16:13:27 [kernel] hdb: command error: error=0x54
Mar 18 16:13:27 [kernel] hdb: command error: status=0x51 { DriveReady
SeekComplete Error }

dmesg je trosku podrobnejsi:
