A friend has added a 1GB Micropolis 1598-15 to their SS2. The disk
was shipped formatted for 512-byte sectors, and that seems to work
just fine. For that sector size, 70 sectors fit on a track.
Micropolis technical support tells me that the drive can support
1024-byte sectors, and then you get 38 sectors per track. That would
increase the size of the formatted drive by 89MB.
My questions are,
1. Can Sun/OS support 1024-byte sectors?
2. Can the Sun/OS format program reformat the drive?
3. What format.dat entry do I want? I read the section on
format, and I don't know how to set the bpt and bps
fields. How am I supposed to know how many bytes make
up the irg and address and data marks? What happens if
I get it wrong? Does the format program then miscalculate
which sectors are defective?
4. Micropolis technical support says that the drive will also
support 4096-byte sectors, but he doesn't know how many
on a track. Should I consider this possibility?
