Well, I don't know how to do a low level format on this machine.. it's an AlphaStation. I ran the following as someone else suggested, it doesn't report any errors.. but later in dmesg I get errors: camcontrol format da1 da1 at sym0 bus 0 target 4 lun 0 da1: <SEAGATE ST410800N 7114> Fixed Direct Access SCSI-2 device da1: 10.000MB/s transfers (10.000MHz, offset 8) da1: Attempt to query device size failed: MEDIUM ERROR, Medium format corrupted (da1:sym0:0:4:0): READ CAPACITY.
