I would definitly rule raidframe and filesystem issues out. This
happened below either of those layers. This is most definitly a
hardware defect: "Media Error".

Some error codes over interfaces abstracted as scsi (usb, for
instance) I take more lightly. If this is a real scsi disk, then the
error is what it is.
