In a previous job, I frequently had to transfer files between ATs and XTs using floppy disks. The AT had only a 1.2M drive, and the XT 2 360K drives. Usually the transfer disks were formatted by the 360k drive, and used for both AT to XT and XT to AT transfers. In many hundreds (possibly over a thousand) transfers, I had only 1 problem, which was a bad disk (wouldn't reformat, on anything but an apple ][). There were multiple XTs and AT involved.

I tranfer files between a PC and AT regularly and have NEVER been able to get the PC to read files written by the AT. Anyone have any idea why this works for some folks and not others? Are their AT drives a different brand than mine possibly? Or, perhaps is it different brands of 360K drives that cause the problem? Any light that can be shed on this problem would be appreciated.
