Has anyone gotten the format program posted by Andy on 6 June to work properly. I compiled it yesterday on a Compaq LTE/286 running a slightly modified version of 1.5 and found that it was taking over 1 minute per track :-( Since this works out to over 2 hours to format a 1.44MB disk I killed the program. It appears to be spending all the time in the format_track() function. Does anyone know anything about this? I had similar experiences with another format program which I think was written by Bruce Evans (it's been a while, might have been someone else's). Do I have some system anomaly? -- Reginald H.

I have used it several times with no problems. Sometimes when things are slow, try chmem to give the program a lot more stack space. I think there are some library routines that call malloc for space, and if there isn't any, do all I/O one char at a time. Please try this and post a short note telling what happened.
