Moderators Augeas Posted January 8, 2011 Moderators Share Posted January 8, 2011 1) Not that long. If you're in Stage 2, cancel it and continue recovery from there. If you're in Stage 1, cancel it. I would run a chkdsk against the drive, then run Recuva in normal scan with Scan for Non-Deleted Files checked in Options. 2) Couldn't really say.

JessicaG Posted January 8, 2011 Author Share Posted January 8, 2011 when trying to run disk check error "the disk check cannot be performed because windows cannot read the disk" so didnt do disk check also, when i tried to run recuva again, error "cyclic redundancy check" i have no idea what to do Link to comment Share on other sites More sharing options...
Moderators Augeas Posted January 8, 2011 Moderators Share Posted January 8, 2011 It doesn't sound too good. Perhaps the boot sector or one of the system files is corrupted. I don't know if any more knowledgeable person will pass by with some advice. Link to comment Share on other sites More sharing options...
JessicaG Posted January 9, 2011 Author Share Posted January 9, 2011 i shouldnot be saying this but are there other programs that can help me? the disk drive contains very valuable data Link to comment Share on other sites More sharing options...
kroozer Posted January 9, 2011 Share Posted January 9, 2011 are there other programs that can help me? the disk drive contains very valuable data If Recuva cannot fulfill your needs visit Cnet which currently offers 48 free Recovery programs. No program can assure recovery, so don't be misled and pay for one that promises results. Link to comment Share on other sites More sharing options...
redhawk Posted January 9, 2011 Share Posted January 9, 2011 CRC errors would indicate you have bad sectors and without fixing them it's unlikely Recuva would work because it quits too quickly on faulty drives. Perhaps using other recovery programs which have a higher tolerance to errors may have better success at recovering files?? Richard S. Link to comment Share on other sites More sharing options...
redhawk Posted January 10, 2011 Share Posted January 10, 2011 There is a very useful hard drive utility called MHDD it has the ability to scan and repair damaged sectors which may correct your CRC problems. Although it's designed for IDE and SCSI drives it does provide USB support via SCSI emulation, whether this work or not depends on your hardware. Just remember to boot with USB support and set "Remap" to "ON" in scan options when you run MHDD. Richard S. Link to comment Share on other sites More sharing options...
JessicaG Posted January 10, 2011 Author Share Posted January 10, 2011 i'm using ntfs hard drive, will it work? currently trying Pc inspector smart recovery, anyone use it before? Link to comment Share on other sites More sharing options...
redhawk Posted January 10, 2011 Share Posted January 10, 2011 MHDD works at a low level it doesn't change the data exposed to the Operating System so it's fully compatible with all file systems. Richard S. Link to comment Share on other sites More sharing options...
