hard drive error test?
 
Hi,

Is dd if=/dev/sda of=/dev/null a reliable test for the hard drive condition? I know there are smart tests, but if I just want to make sure everything is still readable, is this sufficient?


thanks,

No, the disk may correct errors on the fly without you noticing it. A SMART test or usage of the disk's manufacturer's diagnosis toll is the recommended way to do a test.

smartctl --test=long /dev/sda
After a long while:

smartctl -a /dev/sda
You could also look at "badblocks" for another, potentially more destructive, option.

The SMART long test checks for bad blocks already.
