HDD Errors ?!

[Roberto Fichera]

Hi All,

today I found this in my /var/log/messages:

Jun  1 05:26:47 radius kernel: hda: read_intr: status=0x59 { DriveReady 
SeekComplete DataRequest Error }

It's a disk error or a FS error ? What can I do to fix the problem ? I 
500Km distant from this machine :-(
and I want made some check remotely before reboot it.

Any suggestion ?

Thanks in advance.
