Largest hard drive partition size?

I originally posted this back on March 14th, but I guess it got
overlooked in the run-up to St. Patrick’s Day…

Can someone tell me the largest hard disk partition size currently
supported by 4.25? Anything special we need to do to use it?

Specifically, can we use these new 80 GByte drives as a single, large
partition with fsys under 4.25?


Thanks,

Dale

In our experience, the size of the drive has not been a problem unless
you are trying to boot from it. The boot strap must be within the first
1024 tracks. Generally, you can create a small partition with the boot
strap, minimumal OS etc and then mount a second partition (the rest of
the drive) and go from there.

I may be wrong, but you will probably want to make 2 partitions.

You could use 1 partition on the whole drive, but I believe if the boot
image goes beyond cylinder 1024 - the disk won’t boot. To make sure
that doesn’t happen, make a small partition at the beginning of the disk
and keep the boot image there. Have the boot image mount the other
parition as the root and you will have “1” big partition to work with.
