I have 2 USB3 external drives (F: and G:) and use Fastcopy (version 5.8.1) to copy large files containing backups to them. Files are larger than 1TB.
The files are stored on a Windows 10 PC, on local drives E: and D: and I scheduled a BAT file to run after hours.
The target external drives are rotated each night.
Here is one of the BAT files (This one for drive F:. The BAT file for drive G is essentially the same.):
C:usersxxxfastcopyfastcopy.exe /cmd=diff /auto_close “d:backup1” /to=”f:”
C:usersxxxfastcopyfastcopy.exe /cmd=diff /auto_close “e:backup2” /to=”f:”
C:usersxxxfastcopyfastcopy.exe /cmd=diff /auto_close “d:backup3” /to=”f:”
C:usersxxxfastcopyfastcopy.exe /cmd=diff /auto_close “e:backup4” /to=”f:”
The backup to drive G: works fine, but when I backup to drive F: it stops after 2nd file.
When I look at task manager after these failures I see fastcopy.exe running. I end the process and run the BAT file again this time it works.
I thought it might be bad external drive so I replaced the drive with new one. I also changed the order files are copied. Neither of these changes made the problem to go away.
How do I fix this?
