Bitmap Flag = 0x00000001?
 
Hi there,

this *can't* be a mere coincidence anymore, since I've found a wagonload of TOSEC disks with this bitmap flag set in the meantime.

Until now, I was sure there are only two common ones:

0x00000000 = Bitmap invalid
(disk cannot be written to)
0xFFFFFFFF = Bitmap OK

I also tested one of these disks with the '1' value yesterday and believe it or not, even on WB 1.3 I *could* write to it. (I didn't expect that, I thought it must be -1 to allow write access).
So what does this value stand for?

== 0 -> FALSE
!= 0 -> TRUE

Exact value does not matter.

Ohh! That's why it allowed me to write to it which surprised the hell out of me. Thanks :)
