A PC running Windows XP Home
120GB HDD/Gigabyte MB/AMD Dual Core 4200+/1GB

This morning during startup the PC ran a disk check after which a new user was created as if a clean install had been done. After check in Windows Explorer I found old user with files intact. The new user had same name but with the computer name tacked on the end and underlined as if a hyperlink.

Can anybody explain what happened here?

The Disk Check upon start up along with a diffrent profile would tell me you have/had some data corruption.  Find out the brand of hard drive you have and run a diag test to see if the hard drive is going bad.  You can download a diagnostic from just about all hard drive makers web sites.  Or find your self a boot CD that has all the hard drive testing tools on it.  Which I can't mention the name of on Experts Exchange with out getting my comment deleted.

I already ran a Seatools test on it which indicated no errors. It is a Seagate SATA drive.

The PC seems to be performing fine. No further errors have occurred since it did this initial check disk. I have created another user and copied all the files onto that and imported mail, favorites etc. I then trashed the dodgey looking duplicate user. It all seems to be OK but I am wondering if this might happen again. Is there anything else you might suggest considering the HDD checks out OK

Since the last post the PC would not reboot due to missing DLL files. I am doing a chkdsk /r now to see if this will fix it but would this suggest HDD probs despite the Seatools result?

The username.computername profile is usually created when you lose Full Control Permissions to your profile

This can indicate bad sectors/blocks on the hard-drive


the tool you want to run is

HDAT2 4.53
it's main function is testing and repair (regenerates) bad sectors for detected devices

Thanks bRvO
I will try it and get back to you. I suspect Seatools SATA test is not very good.

Did you run Seatools FULL test or just the quick test?

Perhaps nothing is wrong with the drive and you just had data corruption.  
What did the chkdsk report?

I did run full Seatools test and the chkdsk found no errors or could not fix them. After that I did a full Windows repair installation and got same errors again. I ended up replacing the HDD and installing MB drivers now...all seems fine.

I really think it was the HD failure or failing but it is annoying when you don't get something as concrete as bad sectors showing up in the tests. I have also found in the past that running the old PATA Seatools test on a SATA drive can give me differnet results. I did not do that this time but I have found bad sectors on a SATA drive with the old test that the most recent version did not pick up.

I didn't run the hDAT2 test but will keep it for next time.  

If nobody has any further input I will close the question and award equal points and thanks for the responses.

Sometimes software diag's don't detect bad hard drives.  Expecialy laptop hard drives.
Did you format the drive before re-loading the OS?
