best answers are voted up and rise to the top How can I recover files from a disk with crc errors? up vote 1 down vote favorite 1 Details: Windows 7 32-bit 2.5" laptop disk with two partitions (A & B). When mounted via USB, files on partition B can be accessed fine. Partition A was working intermittently, but is no longer readable via any Windows crc health services tool I've tried. CRC error pops up with I try to access the partition, and Windows prompts me to format it. I've tried using various file recovery programs - but all the tools either fail to read partition A when I try to recover files from it, or they don't pick up the partition at all. Is there some way I can do file recovery at the disk level, and not the partition level, to get past this? Or, is it worth formatting the partition A so that hopefully it's accessible, and then running a search with file recovery software on the empty partition? Any suggestions appreciated. (Note: I've look at the other posts and can't find anything that fits my situation. I'm trying to find out if there's anything I can do aside from shipping the disk off to a expensive data recover company - which I can't afford. Thanks). EDIT: Let me put it another way. Is it possible to take an image of the entire disk, even though some sectors of the disk will throw up CRC errors? Because the disk seems to be continually degrading (and USB is slow), my thinking
How to Get Data from Hard Disk after CRC Error? Posted by: Lucy John Follow me: @Lucyy_John Usually many people store their precious data on computer hard drive as data error cyclic redundancy check fix raw they consider it as the safest media to preserve large amount of

data for years; and because of such misconception, they always ignore to backup hard drive data to other

storage devices and unfortunately they often meet to data loss scenarios. Even if users are managing hard drive data carefully, they can experience data loss at any instance. Hard drive http://serverfault.com/questions/315427/how-can-i-recover-files-from-a-disk-with-crc-errors CRC error is a good example that strengthens this fact and anybody can meet such unexpected error. In brief, there is not anything specific which can help you in preventing CRC error on hard disk but fortunately you have technology means that can help you to overcome this problem and you can easily set your data loss. Basically, hard drive http://www.yodot.com/hard-drive-recovery/recover-data-from-hard-drive-crc-error.html CRC error appears when data written to the disk has somehow turned corrupt. In case, data is not correctly written on the hard drive, CRC error will be thrown and then data on hard disk won’t be accessible. OS corruption, power failure, physical damage etc can also result in hard drive CRC error. In Windows users are provided an in-built program that is CHKDSK that scans the hard drive to identify and resolve possible causes. Oftentimes CHKDSK does nothing even after scanning the hard disk for several minutes. Therefore, it is always suggested to go with the proper solution to resolve hard drive CRC error effectively. Best tool to retrieve data from hard drive after CRC error! Yodot Hard Drive Recovery is safe and risk free program that performs read only scanning of hard drive and restores data completely. This application is designed with fastest data recovery modules that check each and every hard drive sectors to re-construct data that is written in wrong pattern or has become corrupt. With this comprehensive software, one can recover data from defectiv

This means NTFS has a CRC for the file. I expect the offending block/sector can be known, or at least guessed. I also expect data error cyclic that "wrong data" can be read from the disk. If the bits of "wrong data" were inverted one by one, by brute force we could find the correct data. A file could thus be recovered using statistics and brute-forcing bits to match the CRC. My question is, does any software do this kind of thing? Any way I could do it (I'd be happy enough to get the CRC, the drive's "wrong" data, know which is the offending block/sector there, and write a script to brute it myself, if relevant directions are given). By the way, this is a mechanical HDD. Edit: After taking a look with hex editors and such, I noticed that a bad block appears as garbage, such as filled with zeros or a copy of the last block (this seems to depend on the program), so in order to get the "real data" that is corrupted, we'd have to disable some hardware-correction that refuses to read a block which is bad. I believe this is called ECC. Also, I expect that if just a few bits are marking a block as "bad", then some 32-bit checksum from Windows could be used to brute force a match. So this ques
CRC Recovery Tool? Discussion in 'Hardware' started by J8son, Dec 19, 2010. J8son Corporal I have three internal SATA drives made by Western Digital (2x 320gigs and a 400gig). In trying to backup data between drives I'm getting the dreaded "Cyclic Redundancy Error" I'm sure these drives are failing and I plan to replace them with a single 1TB SATA drive. However, I must do all I can to recover these files first. I've read that it's sometimes possible to work around a CRC error as it's simply a mathematical algorithm. Can someone recommend a reliable data recovery tool? I'm willing to purchase a good pro level tool for the future. Thanks! J8son, Dec 19, 2010 #1 mcsmc MajorGeek Hi Have you tried Unstoppable Copier? It's good for damaged optical disks as well as the issue you're mentioning. You can download it here: http://www.roadkil.net/program.php?ProgramID=29 Best part? It's free. Personally, while some software is worth paying for, to a large extent I feel like I'm wasting money since almost every software license is worthless as soon as a new version of the paid software comes out. I try to stick to open source or freeware for most of my needs. mcsmc, Dec 19, 2010 #2 gman863 MajorGeek If your new 1TB drive is a Seagate, you might be able to disc cloning using DiscWizard, a free Seagate utility. It usually comes packaged on CD with Seagate retail boxed drives or (if you buy a bare Seagate drive) you can download it free at Seagate's website. I've used Disc Wizard many times; however not for combining three drives onto one. Prior to cloning the drives, you'll likely have format the new drive into three partitions. If interested in this option, I'd go here to download the program and read the instructions to see if DiscWizard will work for what you're doing: http://www.seagate.com/ww/v/index.j...toid=d9fd4a3cdde5c010VgnVCM100000dd04090aRCRD Remember: This will only work with Seagate brand drives. Hope this helps gman863, Dec 19, 2010 #3 J8son Corporal gman863 said: ↑ you'll likely have format the new drive into three partitions.Click to expand... Actualy, what I meant was that I need to do my best to recover the files and then I'll just store them and do a fresh install onto the 1TB drive. Another issue I'm worried about is I'm not actualy sure which drive has the problem. They all have partition problems at this point, which has lead me to invest in the new TB drive. Is there a way to determine which drive is giving me the CRC problems (IE: the M: drive I'm copying FROM or perhaps the C: drive I'm copying TO). Thanks!
