Question - China DOS Union Forum - China DOS Union

Hello everyone:
　　I'm new here. I'd like to ask whether the two commands UNDELETE and UNFORMAT from DOS 6.22 can be used in DOS 7.10. Also, I used the Xiaolvyuan hard disk checking program to check my hard disk and found two bad sectors, then used the HDDREG hard disk bad sector repair program to repair them, and finally used Xiaolvyuan to check it once more. At the end of the check, there was still one bad sector that had not been repaired. What is the reason for this~~~ could you please tell me!!!

Do not use the UNDELETE and UNFORMAT commands from DOS 6.22, because they do not support long filenames, large hard disks, or FAT32. Please use UNERASE 2002 and UNFORMAT 2002, which support long filenames, large hard disks, and FAT32. They can be found in the NU 2002 tool collection.
