that some problems with the hard drive have been detected and all you need to do is enable the check so it can check things out. You can enable that by going to "My Computer" and right click on the hard drive in question. Pick the "Properties" tab and then the "Tools" tab. Then click on the "Error Checking" button that says "Check now". You can also get there by starting "Recovery Console" and type CHKDSK /F at the command prompt.
As far as the reinstall goes, if its working, don't mess with it. Unless you really want to reinstall, it will not cause a problem if it is working correctly, to leave it alone.
I just upgraded my home pc to Core2Duo 2.4gighz and new Intel D975XBX2 mobo - I had P4 and a previous Intel Mobo P875DPZ ...I have Win XP Home Ed w/SP2 (yes - retail not OEM)....anyhow - it worked without messing with XP at all...I just re-connected the HD's and DVD's and it seems to have adjusted to it... I think...
There were a few things asking me if it was a genuine XP and after I installed all the Mobo drivers - it seems fine.
but...I got an error message about my HD saying there are errors reading it during a defrag (that xp did on its own)... and I need to do a ckdsk or something.. it got me worried that it may mess up my main drive (yes its backed up!) and that the HD and XP are getting messed with from the upgrade?
So - Should I be safe and re-install XP, reformate my main drive and re-install all my programs ? or leave it to the XP gods to auto-update itself?
