Had to replace my hard drive because the old one died. the caomputer is a 5 year gateway. pentium 4, 128, 20 gb. Replaced wd200 protege with wd400bb caviar. Bios detects hard drive correctly from what I can tell. Reistalled win dows xp and all updates. The problem is as soon as i power the computer on and before it boots up I get a black screen that reads "a problem with the hard drive has been detected. Consult owners manual to troubleshoot. Press enter to continue. I press enter and everything boots up fine. Windows runs ok and the hard drive shows as working correctly. Other than the prompt at the beginning, You wouldnt know anything was wrong. Any help would be greatly appreciated.
All you have to do now is detect them and rearrange your files so that they avoid doing that. And you can do that through several ways using 'Chkdsk, Scanddisk, and Defrag utilities.
All of them help you out in managing your harddrive.
You can use chkdsk to detect alot of errors on disk by simply
writing
chkdsk c: /f/r
on the run prompt. It will ask you to reboot your computer and then it'll start the scan before windows starts up.
For detailed use of chkdsk, scandisk, and defrag, see the links below.
