ImageDisk / PC FDCs & single-density

Looks like I may have found the problem - It seems in my last update to
"improve" the calculation of gap lengths for unknown formats, I completely
cocked-up the calculation for single-density (left a variable out of the
calculation). The user reports that with the corrected code, he can write
the Osborne SD disk images in question on his Adaptec 1522A controller
without any problems.

I've asked him to run a couple of other tests, and if all goes well, I should
have an update to ImageDisk posted on my site by noon tomorrow.
