Hello,

Does FreeBSD (stable) have any tools that I can use to run diagnostics
on an external hard drive?

I have a Maxtor One Touch 250GB external hard drive (the one with both
USB and Firewire connectors). This is connected to my FreeBSD 5-stable
machine with firewire.

>From /var/log/messages:
Mar 12 21:29:38 kg-work kernel: da1 at sbp0 bus 0 target 1 lun 0
Mar 12 21:29:38 kg-work kernel: da1: <Maxtor OneTouch 0000> Fixed Direct
Access SCSI-4 device 
Mar 12 21:29:38 kg-work kernel: da1: 50.000MB/s transfers 
Mar 12 21:29:38 kg-work kernel: da1: 239371MB (490232832 512
byte sectors: 255H 63S/T 30515C)

Today the drive suddenly stopped working, and when I try to mount it now
it says:
root@kg-work# mount /dev/da1s1e /mnt
mount: /dev/da1s1e: Input/output error

In /var/log/messages I see lots of error messages
(see attached file).

Maxtor have a (Windows-only) tool that will do diagnostics, but only on
"One Touch II" drives, not on those who are only "One Touch".
So any tool I can use under FreeBSD will help. The drive is still under
warranty, so I will not open it (yet).

Any hints appreciated.
