I would like to manually position the head of my hard drive, just to hear the noise it makes. I'll use an old drive just in case it breaks. Any idea where to start? Thanks.


You can instruct your system to read a specific sector by specifying a number of sectors to skip, e.g.:

dd if=/dev/sda bs=512 skip=1500 count=1 > /dev/null

to read sector 1501.

Alternatively, you could use hdparm like so:

hdparm --read-sector <sector> /dev/<hdd>

That could bypass caching, and may therefore be better, but the startup-time is perhaps slower than dd
