The process has stopped. The software diagnostic
code (exception code) is 009B.
Even if it didn't crash with a "divide by zero" error (009B), 'Diskio' would be unlikely to provide useful info about my disks. Both of them are GPT and are normally *hidden* from the system by 'gpt.flt'.
What OS/2 sees are a bunch of _emulated_ MBR disks, one for each mounted partition plus a few spares that appear to be unpartitioned. Doing a speed test on a phony disk that refers to some partition somewhere on one of the physical disks wouldn't be overly informative. In any case, I don't think you can access them using the Physical Disk IOCTLs that 'Diskio' depends on, so we'll probably never know.
FWIW... GPT disks can be made visible, though I'm not sure how accessible they are. I look forward to trying 'Diskio' again with the disks visible once the current crop of issues is resolved.
