Dos Formatted IDE Zip Disk on QNX4


I’m having problems mounting my dos formatted zip disk onto qnx4. QNX4 sees to automatically load Dosfsys when it boots up so I thought that if I were to just go to /dos/___, it would read the zip drive. However, I keep getting a corrupt file system message when I try to access the drive. Any suggestions?

Another question. When I mount a qnx formatted zip, accessing the zip seems several times slower than if I were to use a parallel port zip drive. Is this a driver issue that the IDE zip drive is slower than the parallel port?
