Looping problem... heard it's an XP issue, any ideas?

[apollos]

Recently, my brother who incidentally has the maturity of a foetus, turned off the power on and off a few times, as a way to "punish me" and now every time I start windows my slave F drive loop check disks, and whenever I go to defragment the drive it says it¢s unable to because "chkdsk is scheduled to run on the volume"

Does anybody have an idea how to solve this issue? Thank you all
