Hello,
I am supposed to get files out of an very old computer.
It is an IBM Personal System/2 Model 50. It RUNS with MS DOS 3.3.

The files I need to save are .lib-files (containing the whole meta information of a Library).

It is possible to copy them successfully to a 3 1/2 floppy disk, but when I put the floppy disk into a drive of a more modern computer, the system tells me "there is no disk in drive". I tried with different computers here. They all announce the same message.

I assume a problem with the DOS version. The floppy disks have been formatet under the old system DOS 3.3. The modern computers use much higher versions. Maybe this IST the point. . . .

However. ... I need somehow to copy the data to a modern PC.
Is there a solution?

I am glad for your help,
SPOON123I have done something similar to what you're doing. My intentions weren't recovery, but I managed to get into a ~14 year old computer.

What I did was simply hook the HARD Drive up as a slave on my desktop and access the files within Windows.I had also the idea to connect the hard drive as slave to a modern computer, but it seems the hard drive in this old IBM PC is fixed within the case, furthermore the connection to the the rest of the system is totally different in the old PC.

It is an 20 MB hard drive, IBM, Model: WD-325N

There are several more informations:
P/N 90X6806
Type 30
20 MB
MLC: A07282

How did you manage to connect to your modern system?

With a lot of thanks for your help,
SPOON123Suspect it is an ESDI hard drive (look it up) totally incompatible with modern stuff.

If both computers have serial or parallel ports you can use file transfer software such as LapLink with a link cable



Thank you very much. I will try with the software and the serial connection.ooohh... a PS/2 System...

What happens if you format the floppy in another machine and attempt to use it on the PS/2?
