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.

Hi Curtis. Help refresh my brane a bit…

I never played with adjusting the cluster size because I had read so many utilities did not honor it and could cause corruption. Did you run in to that?

By default, OS-9 shipped with a cluster size of one 256-byte sector. This made the smallest file, like a text file just containing the text “42”, take up 256 bytes on the disk.

Would using 255 mean that same text file of “42” would now take 255*256 bytes (65280 bytes)?

Hmmm, is it really 1-255? What happens if you put zero there?
