A disk read error has occurred

A disk read error has occurred - one morning you turn your computer on and all you get is this message, this is how I fixed it. There are 1,000's of messages on the net about this problem, this is the only one that worked for me. I tried all the chkdsk, fixmbr, drive jumpers, IDE cable, bios reset cures and none worked. Luckily I had Ghost 2003, which I used to copy the faulty drive to another same size drive, inserted in the computer as a slave drive. When the copy is finished, shutdown, remove the original drive, make the new drive master and hey presto, everything worked as normal, same desktop, docs etc. etc. all back again. Why does this work ?, something to do with the Ghost copy fixes the problem. Good luck. Tip, make sure you copy from the faulty drive to the new drive, otherwise you lose everything !
Disk read error - fix number two, get your hands on a USB to IDE adapter, plug in your problem drive and run the windows disk defragmenter. Don't ask me why it works, it just does.
Disk read error - fix number three, same as above but plug the problem drive into another computer as a slave drive and run disk defragmenter.
Disk read error - fix number four, download Ultimate Boot CD for Windows and burn it to a CD. Boot your problem computer with this CD, and run Disk Defragmenter from the CD. Problem solved without having to dismantle anything!
