on one of our systems Explorer(process) froze (no Start / task bar/ desktop access, ctrl alt del is unaccessable) while running a scan ~81.5% scan would have continued slowly it got to 81.6%
but i stopped the scan and regained access to explorer.
I had 1 Quickbooks and 2 Firefox Windows open alongside recuva, hard drive 40Gb 2+Gb free,
will try again with them programs closed.
::edit::
Even with Qb closed and 2 Firefox windows open, it still stalls explorer
::edit::
closed firefox.
Maybe its Nero InCD,or hard drive space.
I closed all unneeded and needed programs ie: antivirus(Nod32) firewall (Sunbelt Kiero -last freeware), spybot, google desktop, anti spam(popfile).
::edit::
I ran the scan on some of our other partitions one 18GB with 2Gb free and it scanned fine, so i still have no idea why, may be some kind of system file/process recuva looks at while scanning C:\
