Error data error cyclic redundancy check failed to read data from the file

I also have this error.

2017-02-19 1:25:42 AM :: Error: Data error (cyclic redundancy check). Failed to read data from the file [\?GLOBALROOTDeviceHarddiskVolumeShadowCopy195].

Failed to read data from the file [\?GLOBALROOTDeviceHarddiskVolumeShadowCopy195]. The block at offset 9293529088 (length 1048576) is corrupt. Unable to ret 

This error refers to the source (computer), right, and not the target backup device?

I wanted to back up my documents before running checkdisk in case checkdisk mangled anything. I created a new folder on the NAS and changed backup from «Entire Computer» to «File Level» and selected the 2 /Program File/ folders, /Program Data/ and /Users/ — this backed up OK.

Windows 10 — I ran Windows checkdisk which reported no errors, then defrag and checkdisk again which again found no issues.
QNAP 2 disks (mirror RAID) — SMART info is all good for both, I am currently in the process of running complete test on those disks nonetheless

After running checkdisk, I tried «Entire Computer» again, with the same CRC error. So something in the Windows system files is corrupt?

Is the error text accurate [truly bad/corrupt] or can it be something else (NAS is ‘low’ on space currently, my C; is 200GB, NAS had 466GB) or a permission error? Since the error references VolumeShadowCopy195 — if I make Windows delete that numbered shadowcopy or some or all other restore points, could that fix it? Does to have to do with space alotted to restore points? Is Veaam absolutely only reading in there or causing any writes in there?

Is there another utility you may suggest that could confirm bad blocks since Windows itself isn’t detecting any issue ?

Data Error Cyclic Redundancy Check FAQ

When you are in the middle of rushed copying some crucial data from one drive to another and suddenly a screen pops up, saying “Data error!” You start to wonder What is Data Error Cyclic Redundancy Check, why it failed and how do I resolve it?

Well, you are in the perfect place to find out. Cyclic Redundancy Check or Simply CRC is a check performed by the file system to check if the source file and the destination file are the same, i.e. if the file has been successfully copied or not. Instead of comparing each bit of data of both the files, some checksums are generated and then they are compared to see if the files are the same.

Now, two things can be wrong with copying the data.

1. The source file or the Drive on which the file was stored initially is corrupt, or
   The destination drive is corrupt leading to no match in source and destination files, as the file could not be copied accurately.
2. If the file or files that gave the Data Error Cyclic Redundancy Check messages are not much important, you can simply permanently delete them and copy the rest of the files. But if they are essential, you will have to recover them.

If you get the Data Error Cyclic Redundancy Check screen while copying some files, here are some things you can try to resolve the problem:

Method 1: Recover the Source Files

There are many Data Recovery Software available on the internet. Some of them are paid with a free trial and some are free. When you delete or move or overwrite a file from any storage device, the special hidden file that contains metadata about the files and folders simply deletes its entry, not completely removing every byte of the file.

The Recovery software makes use of this, and rebuilds the metadata file, making the deleted or corrupted file available again, and you can copy files now without the Data Error Cyclic Redundancy Check message.

Some of the data recovery software include Minitool Power Data Recovery, EaseUS Data Recovery Wizard, Recuva, etc. All of them are designed to do the same thing: recover corrupt or deleted files from a drive or recover files from a lost partition.

Method 4: Renaming the Drive (Assigning a drive letter) if a Drive is Not Accessible

In some cases, the windows operating system does not automatically assign a drive letter to a newly connected drive or de-assigns it for safe disconnection when idle. If that is the reason the drive was not accessible, you can rename or assign a drive letter to the drive to access it.

Follow these steps to assign a drive letter to a drive or a partition in Windows:

1. Firstly, Press the key combination Windows + R to open the run… dialogue box.
2. Secondly, Type “diskmgmt.msc” in the text box provided without the quotes and press the Enter key.
3. Disk management tool window will open if you also see the drive you want to assign the letter to. Right-click on it. You can identify different drives from their sizes or file systems. DO NOT mess with small partitions that are reserved for Windows operating system’s safe operation or you may end up screwing up the OS and PC won’t boot, which in turn will end up in you losing all of your data.
4. In the menu that pops up, Select Change drive letters or paths.
5. If there is any drive letter associated already, select change or select add if there was none.
6. Assign a new letter to the drive, ignore any warnings if anything pops up.
7. Close the windows and reboot.

See if this change in drive letter allowed you to access the drive now and removed the message Data Error Cyclic Redundancy Check.

Method 5: Check for Bad Sectors on a Hard Disk

If the source or destination drive is corrupt and hence resulting in a Data Error Cyclic Redundancy Check error. Maybe it is time to replace it or get a warranty replacement if it is still under warranty.

Drive getting corrupt may have many causes like the mechanical failure of the hard drive due to accidental shut down. That too due to bumps or drops causing the head on the hard drive to dislocate and damage the drive. Or ejection or drive when data on it or read from it.
