Subject: Free blocks...
|
Hi all,
how can I calculate the free blocks of a D64 image? I read in the
"Big Floppy Book" the following.
On the 18th track, 0 sector is the BAM. There are 35 tracks, every track has a 4 bytes long entry, the first entry stars at the 4th byte of this sector. The first byte of every entry contains number of free blocks of its track. Simply sum these numbers and you will get the free blocks of a disk.
But I always got bigger values than the amount of real free blocks.
What is wrong?
Greetings,
Zsolt
