[Coco] Tool Shed Issues

[L. Curtis Boyle]

Actually, RBF has an internal limit of 2048 sectors (or clusters) per segment. It has to do with buffering the allocation table one sector at a time. Setting the drive’s device descriptor with DMODE to force SAS=ff (to force it to attempt to allocate at least 255 sectors per cluster) helps make bigger files within NitrOs9; not sure on the utility.

This allows a lot more than 3 or 4 MB (and I know we did that at work regularly) per file. But a high SAS setting was pretty critical for that working.
