OK, here's my 2 cents worth. ;-)
The actual limiting factor is not the total storage capacity of the
partition.
It's the total number of clusters that causes the snag.
DOS has a limit of 64k as the number of clusters.
(can't remember if it's 65535 or 65536)
When I originally partitioned this 5.7gig HDD, I made the mistake of
choosing a partition size that was a liitle too big on 7 of them.
(1 cylinder too big to be exact)
I have now rearraged the partitions to be like this.

As you see, the cluster size is now 8k per cluster on all of them.
I was going to reduce the size c: and d: by just a little bit so that
they would have only 4k per cluster. But then I would need a 10th
partition to keep one of the other 7 from going to 16k per cluster.
BTW,
As you can also see... every partition is only 3 days old.
That's because that one bad cluster on drive C: is cluster 0 of cylinder 0
Yes, my entire DOS system was down for 2 days untill I was
able to fix it using Linux.
