Backup Operation Failed

Hasleo Backup Suite Ver 5.5.2.3 Build Dec 5, 2025 Win 11 Pro 25H2

I was doing a disk backup of a HDD and I get this message:

The backup operation failed, please contact us for support.

There are bad sectors on the drive. (0x07540069000001B1)

The operation was not successful.

 
I did a chkdsk on the disk I was backing up and on the destination disk.
I can't find this error code. 

I have a zip of the log files.

Can someone help me out?

Thanks

Not too much detail in your post but in general, the bad sectors don't have to be in C, they can be in the smaller partitions or any other included in your job.
The small partitions often do not have drive letters assigned so to chkdsk them you have to assign a letter which can be done using Window's Diskpart via a Terminal. Right-click on the blue Windows icon and select Terminal (admin) - admin just in case you need the admin permissions. You can/should remove the letter after checking.
Did you use chkdsk [partition letter] /r or just /f? /f checks the file clusters in use and you would think that would be adequate, however, /r checks the whole partition and can sometimes pickup bad clusters causing a problem. Unfortunately, for a large partition /r can take a long time.

Thanks for getting back to me. I was backing up my D: drive. According to  Disk Management that disk only has one partition. I checked the drive by right clicking on it selecting Properties -> Tools -> Check. I thought this was the same as chkdsk, but just realized that it isn't. I also ran CrystalDiskInfo and it said it was in good health. The disk is 8 TB but only using 1.38 TB.
Should I run a chkdsk D: /r on it?
