I am having some read errors with compact Flash on my Tandy 2500 SX. The machine detected the card, and it installed MS DOS 5.0 to the card, up to the point where it was reading command.com to write the master boot record, at 99%, then it failed. I then booted it in plain DOS using a boot floppy, the result was that while I could list files on the CF Card with 'dir' if I used 'type' to read a file, I was given a "Not Ready reading Drive C" error. What is going on?
