bad blocks and disk errors

Folks,
I've been having problems with creating an Image drive using NovaStor. I presented them with the logs and here was their response:

Thank you for submitting your logs.

Unfortunately I have reviewed them and have discovered that you have bad blocks and disk errors like crazy for both your Seagate backup drive and your Toshiba backup drive. Until these disk errors have been corrected on your end then we can try the backups again. I suggest having an IT professional diagnose the issue with your drives.

Is there any reliable software to repair ba block and disk errors ( ran chkdsk repair but apparently that needs additional help)

There's no way to repair bad blocks.  All that can be done is mark them as bad.  When a disk starts producing significant numbers of bad block errors it's time to get rid of the disk.  Don't keep it around even as an "emergency" drive.

When a drive starts producing bad blocks in abundance there's something physically wrong with it.  No software solution can cure that.  You'll see advice to run this or that program which will "regenerate" the blocks.  It won't; it'll just mark the blocks as bad and revector them using blocks from the free pool.  But the drive is still problematic.  Same thing for doing a full drive error detection and revectoring using the manufacturer's software.  The drive will very briefly act as good as new, then it will start producing more bad blocks.

Check the SMART status of both drives using a program such as the freeware Passmark Disk Checkup.  If it confirms that the drives are producing significant numbers of errors, then replace the drives.

On the other hand, if Windows does not confirm that the drives are producing significant numbers of errors, then look in the Windows Event Logs and see what Windows thinks.  If Windows confirms that the drives are not producing drive errors, then it may be prudent to do a software differential test -- i.e., try some product other than NovaStor to do the imaging and see what happens.

But if the drives are really bad, chuck 'em out.  It is a temptation to keep them around "for an emergency."  Avoid this by taking a hammer to the drive's controller board.

By the way, there are really neat extremely strong magnets inside that are well worth extracting before sending the drive to recycling.
