Minor Bug in VTOCFIX.COM

[+Larry]

There is a minor but annoying bug in Bob Puff's VTOCFIX.COM 1.2. This is a utility that can help maintain/fix MyDos (and other Dos 2-like) disks.

 

The bug is that it frequently reports the VTOC size to be off by -1 sector. So if a sector is set up in MyDos to be 20,000 sectors, VTOCFIX will report it as 19,999 and ask if you want to correct it. 99% of the time, I just say "no." I guess it also could be a MyDos bug.

 

Does anyone have any more info on this issue?

No it is not a Vtocfix bug. It is a failure in ATR system.

 

When I create a 65535 sector sized ATR. And I format it... There is not 65535 sectors allocated, but 'only' 65534.

 

As soon as I run VTOC Fix (which will see: 65535 sectors) it will report an error on this.

 

On 'real' harddrives (not sio/atr based) this issue does not occur. Well... not to mine partitions at least.
