What causes intermittent freezes in Ubuntu server 12.10?

Question

Hard disks

There is a server (file dump) running ubuntu. It has a cron job set up for daily backup via rsync to an external usb hard drive.
Without any periodicity in the morning, I find the server tightly hung. Not available over the network, a certain log flaunts on the screen: I set up a smart check. in webmin System Information the message flaunts:

Drive temperatures sda: 33℃ (282 errors!), sdb: 28℃

command # smartctl -l error /dev/sda:

Actually the question is: will the hard drive die soon? Can this be prevented?

Answer 1

No one will say exactly when the screw will fail. Change as quickly as possible if the data is important.
