This is probably a real easy question, I'm just not finding what I'm looking for partly because I'm not exactly sure what I'm looking for.
On my old computer I had an option in the 'System Tools' to scan my computer for errors and it would automatically fix what it could. I can't find that option on my new computer. I'm not sure if I accidently deleted it, or if it's called or located differently. I'm having a hard time searching for it on my computer, because I'm not sure what it goes by. Can this be redownloaded? I'm sure I must have it in the stack of disks that came with my computer if I can't just get it off the net. Then again maybe it's there. Can I get some help getting pointed in the right direction.
Sounds like you are looking for Scandisk. Open up my computer, right click the Local Disk, and choose properties. Click Tools, and there you will find both the Scandisk Error Checking, and the Disk Defragmenter.
Acid is pretty cool. Have you tried Fruity Loops? You might like it. I think there is a demo you can download. Garage band is pretty nifty but you need a mac. For your MP3 stuff, I'd recommend Audacity and CDEX, both available from Sourceforge.net.
