[Coco] KenTon - determining size of SCSI hard drive? (RGB-DOS HD-UTILS)

[Mark Marlette]

Allen, SuperDriver will query the drive but requires about a 2004 or newer version of NitrOS-9 v3.xx??
 There are bits in the descriptor, etc. To tell the driver to query size. If you have partitions you want to make sure you don't or you won't have your partitions. 
 Check out the documentation of the support section of the Cloud-9 web site 
 There currently is a thread on building scsi driver for the TC^3.   Regards,

But that's only useful if it's previously formatted at the correct size. In this case, I don't actually know how many sectors the drive has. :-(

Good idea. I did, but am only finding "135 MB". And I know that's marketing MB, 1000/bytes per.

I know it's really a 128MB, but I don't know exactly how many sectors. I did find a few pages on it, including one as recent as 2011, but they don't mention sectors.

I manually wrote out to 7FFFF sectors, I think, before errors, so I guess that's it. It's a few sectors larger than what OS-9 can use, but dEd was still able to get that far.
