Default HDD goes read-only. Funky error output

I'm working on a linux cluster at my Uni and one of the nodes keeps going bonkers on me every so often. As far as I can tell, there's some error with the HDD and it turns read-only. When I looked at the output coming from the screen it gave me this (wrote it down as login doesn't work):

ata2.00: status: { DRDY }
ata2.00: exception Emask 0x0 Sact 0x0 SErr 0x0 actiona 0x2 frozen
ata2.00: cmd 25/00:20:ef:7f:31/00:00:2x:00:00/e0 tag 0 dma 16384 in
res 40/00:01:00:4f:ce/00:00:00:00:00/00 Emask 0x4 (timeout)

end_request: I/O errpr, dev sdb, sector 741441519

Any idea what the hell is going on? This has to be at least the third time it's happend.

Many thanks.
