Can I defrag an MS DOS 3.1 hard disc?

April 17, 2011 at 03:22:54
Specs: MS DOS 3.2.1

Still have an old computer with the MS DOS 3.1 operating system that has old files I still usel, but now the disc is full. I understand that in the 80's you could purchase a defrag utility form other companies but never did. Can you defrag this disc with the MS DOS 6 defrag tool that I see advertised?

"Can you defrag this disc with the MS DOS 6 defrag tool that I see advertised?"

What tool? DOS 6 had it's own defragmentation program built-in. I'd be suspicious of anyone trying to sell a "tool" for DOS nowadays. No reason though that you couldn't pull the files from a DOS 6.x folder and use them on the DOS 3.1 machine. But if the drive is completely full, you'll have to get rid of something to copy the files over.

Also, FYI: Defragging the drive won't do anything to free up space on the hard-drive; better to backup the files you need on something you can depend on...

You cannot use the 6.22 defrag utility with older versions of DOS. I have IBMDOS 5 and tried to use it and it would not work. Since DOS 3 is much older, I would expect the same result. However, I did find another DEFRAG utility that was made for PCMAG in the early 1990s that worked great:

v12n04.zip

As the other guy (TRA) said, if the disk is full - defragging doesn't solve that problem. Backing up and deleting files is what needs to be done first. In fact, you should never use a defragger on a fullish disk because the defrag utility needs ample temp space for reorganizing the disk.

Full backups should be done anyway before a defrag on systems before the 6.22 DOS.

Odd. I pulled the defrag files from DOS 6.22 and used them on a DOS 5 machine with no problems (though I'm not doubting there may be an issue). If so, then an older version of Norton Utilities should have a defragmentation tool that should work.

Nonetheless, if the DOS 3.1 machine is one you use routinely (or plan on using for some while), it may be of some benefit to go ahead an upgrade to a newer version of DOS 6.x, assuming you have access to the disks.
