It doesn't work like that. You can't move a dump from one hard disk to another, because if it has different number of sectors it won't work (because the way WFS works). You can only move the dump as is to another hard disk with the exact same sectors number. So I recommend something else, dump all the files from the hard disk with wfsdump, than get new hard disk, install all the games again and just restore the save files with the appropriate Homebrew.
Anyway, run this in admin console:
wfsdump --input \\.\PhysicalDrive3 --output dump_dir --otp otp.bin --seeprom seeprom.bin
For more information on admin console and finding the correct number of the disk read Option 1 here:

Now you should have all the saves in dump_dir/use/save
