Windows Error on startup - "The type of file system is RAW" - still boots but soon crashes

Hi,

I've had a sick laptop brought to me and I need some help.

On start up each time Windows starts up it always gives the following error message

Checking file system on C:
The type of file system is RAW
AUTOCHK is not available for raw drives
Windows has finished checking the disks

This is not displayed for very long.

When actually using Windows sometimes it is OK for a while but at least 50% of the time and all of the time eventually the PC will freeze.

If it does not freeze right after Windows starts (Explorer just seem to stop responding) it does sometimes give the error message:

"Failed to get sessions notifications"

Does anyone have any idea where to start with this. I noted there is a restore point before the problems were reported to have started but I would like to get a better understanding first in case it made things worse.

Thanks

Thanks for that so far.
I'm not quite sure the postings so far help. The first one suggests a virus may have caused this and I shuold scan for them. I quite agree this is a possibilty, but that is in relation to the error message that happens once Windows booted.
I would have thought the file system error would need to be addressed first.
The second scenario is a case where they cannot access the hard drive at all and suggests permissions. Well in this case the hard drive does actually boot up and is acceiable.

Any other ideas on how I could address the first problem that occurs on the PC and that is in early boot up it reports a RAW hard drive but still goes on to start up.

Thanks

Do you think there would be much point in runnig a system restore to a time back before the problem started?

I'm suprissed I cannot find more infomraiton on this problem
Sure you can try that but after you copy off your data first.
In the end just installed a new hard drive and re-installed. Even if the drive was fixable it was not worth the complication of doing it any other way even if I did have to bring across all of the files.
Thanks for the input.
