MS-DOS 2.11 was the most heavily customized one.
It was NOT available directly from Microsoft, only as a customized version
from a computer OEM.
Several companies added support for 720K 3.5" disks in their versions of
2.11
NOBODY supported 1.4M in 2.11.
(IBM didn't add 720K support until PC-DOS 3.20 and 1.4M in 3.30)
I am therefore going to guess that you are using a 1.4M diskette, but that
your computer doesn't know from 1.4M and is treating it as if it were a
720K. When you bring that 720K format that is on a 1.4M diskette to your
modern PC, it fails due to the diskette having a different format on it
than the PC expects based on diskette type. Try using a 720K floppy.
However, to further add to the fun:
Since 720K support was locally originated by individual comoputer OEMs,
many of them did NOT use the same format that IBM eventually
adopted. Some did, some didn't. For example, HP had several 3.5" disk
formats that are incompatible with PC. Gavilan's version of 2.11 uses an
incompatible 3.5" format until rev L? of their 2.11, when they switched
format.
What is the make and model of the computer?
In a few cases, the "alien" machine will recognize PC formats and accept
them, even if the native format is different. Try formatting a 720K
floppy (AS A 720K!) in the PC (FORMAT A: /F:720); take it to the alien
machine, try to copy files to it, and bring it back.
If that doesn't work, you MIGHT need to consider other transfer methods,
or special software. http://www.xenosoft.com

There are some data on that machine that we need to
retrieve. The information is transfered from that old machine to a 1.44mb floppy.
When we put the floppy into our pentium winNT4 computer , we can not read the information
on the floppy. The NT os simply says it does not know what format the files are at.
Now do I need to install a dos 2.11 or is there anyway around it ?
What is the format the dos2.11 writing its files in?
Are there any program that reads in that type of format?
Does any one here have DOS 2.11 that I can download?
Even if I do have DOS 2.11, will I be able to install it or do I need very old hardware
as well?
