Hi guys,
I've got an IBM PC 5150, and I'm having floppy disk trouble. I have two Tandon TM100 drives (a -2A and -4) that both display the exact same problem.
The first symptom is that it won't read floppies that are known to be good. You can occasionally get a directory listing, but if you try to copy or otherwise read a file, you get "Sector not found", and it won't go any further.
The second symptom is that even though it will get 100% of the way through a format and display the message "Format complete." without any problems or head-seeking sounds, at the end it says "Unable to write BOOT" and fails. This process can be repeated with any number of known good floppy disks, and every time it's the same. Even if I try "format a: /u /1" to just format one side.
The system contains an Adaptec MFM controller and a Seagate ST-238R, which is what I'm booting from. It came with MS-DOS 5.00 installed. The symptoms are identical for both floppy drives, and I don't have any other 5.25" floppy drives to test with. (Well, unless you can use an Apple II drive! )
Any ideas?
Found this thread by LGR/phreakindee, but there doesn't seem to be any resolution at the end? I've got a few things to try now though...
