I had a scary moment the other day whilst making a routine backup image of my data drive. I got the following message:
Backup aborted! Unable to read from disk - Error Code 23 - Data error (cyclic redundancy check)
According to Macrium's support page (
v5: Imaging disks with bad sectors (Bad Sectors)), if a bad sector is encountered during image creation then you will receive that error in your backup log. This is considered a fatal condition because your data cannot be read and the image will abort.
As instructed by Macrium I ran a full checkdisk including repair option. However, chkdsk went off and a few hours later reported back, no bad sectors, no repairs needed...0 bad file records processed....Windows has checked the file system and found no problems. The only thing it did say was that there were 46 unused index entries cleaned up from file 0x9, whatever that means.
So is my disk failing and in need of urgent replacement (according to Macrium) or is it in perfect health (according to MS)? Kind of important given it's still under warrenty and I thnk I'd have a hard time presenting a normal healthy disk to the shop and asking for a replacement!
