Disk I/O Error

[Dawntreader3]

I have been trying to install a scavenged hard drive into my computer (Both the original hard drive and the new one are Compaq's) and after the computer recognizes that there is a hard drive I get this error message "disk I/O error, Replace the disk and then press any key."
I have tried repeatedly to find help through PC troubleshooting manuals, PC repair manuals, and even online help but nothing and no one seems to know what to do other than take it to a computer store and try to have it fixed.
If there is a feasible way to cause this scavenged drive to boot could anyone please tell me what it might be?
Thanks in advance!

Disk I/O errors are usually due to a bad controller. Does the same error occur with every drive you install in there?

Compaq does funky crap to its harddrives to prevent the very thing your trying to do. My father is a Network Tech at a plastics manufacturing company, and every once and awhile he has the god awful job of fixing a broken Compaq. He contacted Compaq about this and if you dig deep enough someone there will admit they screw with all there machines and parts. I dunno how they do it. Let this serve as a warning! Compaq is evil!
