The other day on boot up I received an "lsass.exe error, invalid parameter" screen. Clicking "OK" just continued the boot up and error message in a loop. This has been a common problem for folks. Although I could not determine (due to the state of the system) if in was a virus or a corrupt file, I was finally able to coerce, after many varied attempts, an overlay install of XP Pro. However, all that was on my hard drive dissapeared (programs, settings, files). Although, when I went to reinstall some items (Adobe Acrobat, for example) it stated that it was still resident on drive. Further, when I went to do a defrag, it stated that it was not needed (probably because of the small amount of recent installation) but the graph showed 20 gigs of space taken up (my original 18+ gigs and the new install). So, the original installed volume is still on the drive yet I can not see it or access it. Any thoughts as to how to retrieve this info? Also, will accessing it reintroduce the lsass error? I have the data backed up separately but am concerned about accessing that because of the lsass (my current thinking is that if it is a corrupt file then it is in the original XP Pro install but if it a virus, it may be resident with the data). I tried searching for some of the files but they did not show. Thanks,

William

The virus version uses a capital > L < Lsasss.exe ( Sasser virus )

Probably slaving to another comp, running a virus check & copying the HD contents over, is the best way to go.

Slave it to another HD/comp ( no need to bolt it in, just cable it & leave it outside the case ) & copy your stuff onto the other HD.
You may have a choice of jumper settings on the master HD, such as master with slave or ms.
Now put it back in your comp ( change the jumper, back to where it was )

You can now use a recovery program or registry repair.

Another possible.

Data Recovery with Linux
http://www.linuxiso.org/
One of the best tools for Windows data recovery is Linux? When all else fails and you desperately need information off of your hard drive, Linux is your safest bet. One of the best CD-bootable distributions out there is Knoppix (available for free at www.knoppix.org). Knoppix will allow you to not only possibly recover lost data that Windows simply cannot access, but also potentially fix hard drive errors and partition tables.
