Yeah - you might need it...

hdparm -i /dev/hd<x> is the first thing to do - this will
tell you what the drive can actually support.

Then, check your BIOS to see what the motherboard can support.

Then, man hdparm and read all the details about why -X68 is
extremely risky.

*Then* you're ready to work out an hdparm line.
