Hard Drive Locked?

[ultranet]

Hello to all

I am sorry If I posted in wrong forum, But I need help asap :(

I have a problem with a PC that I cant figure out. I was running a little routine maintanance on the machine(P100, Win95, 32 megs RAM) using Nuts & Bolts and in the middle of the defrag process the system locked up on me. I had to ctrl-alt-delete to get out of it and that produced a blue screen letting me know the system was busy, blah blah...but now when I reboot it will only let me boot into safe mode, and running scandisk turns up the response that a disk utility has locked the drive,and that I should close the program or wait for it to end. I have no clue as to what may have 'locked' it, or how to even go about 'unlocking' it.
Please suggest

Thanks

A few ideas, I have 1...
P100??? REALLY???
1. how much Left on the HD...Windows has this little THING, about 30% NEEDED for anything to run.
Sence you probably only have 1 HD, and its about 20 gigs, MAX....you need to KEEP 6gigs FREE...NOT LESS.
With all the cacheing windows DOES, and the HD cache when you need more for the RAM and video card....THAT is the minimum...
2. what needs to be done is a File by FILE restart...It should be in the safe Start(F8)..
Should be the LAST listing in the reg..LOOK at EACh file and READ every line.

If you get it started, run a prog to CLEAN the reg.
