I have SATA Seagate Baracuda 320GB harddisk ...

After running my system for sometime
Sata harddisk gets shutdown on its own and is inaccessible after wards.

I got these messages using "dmesg | tail"

Is there any way i can turn on the harddisk again without rebooting my system ?
Or
Is this a driver issue in Debian .. Harddisk works find in windows ?

Your disk is dying. You should replace it ASAP.
