Yes--usually it's a program in the disk firmware.

You can steer it and look at what it did using smartctl (in package
smartmontools).

But I'd advise to check dmesg because it could also be a RAM problem, or a
number of other things.

(UNIX also has fsck to check the filesystem, but it already automatically
does that on reboot when problems arised.  So little need to manually
fiddle with that)
