DISK ERROR??

[L]

Hi

I have a small network attached storage (NAS) linux.  when it
boots up, there is a bit error from kernel message:

<3>ata1: translated ATA stat/err 0x58/00 to SCSI SK/ASC/ASCQ 0xb/47/00
<4>ata1: status=0x50 { DriveReady SeekComplete }
<4>ata1: error=0x04 { DriveStatusError }
<3>ata2: translated ATA stat/err 0x58/00 to SCSI SK/ASC/ASCQ 0xb/47/00
<4>ata2: status=0x50 { DriveReady SeekComplete }
<4>ata2: error=0x04 { DriveStatusError }

Is this disk error, a serious problem or can be ignored? if it is
serious, this device is under warranty, I can contact manufacturer.

Besides this error message, the system seems working. How to check
heath of disks?


Thanks

Y
