Hi Daniel!

I am tryin to install FD on a Dell PC with an 80 gb partition.  I tried as
I prefered it spliting into 4 partitions, and as one large partition.  When
I boot into the live CD all seems fine, but after it does the formating and
installing, I get a bunch of errors about the partitins.  Looking at the
fdisk informations they seem to get changed from 20481 to 20489.  Not sure
why.  Can anyone check to see if this happens to them?  Is there a size
limit currently for partitions?

Please share more details about the issue. If you want to have
4 partitions of 20 GB each, you will have to use FAT32, but it
is possible to have much larger FAT32 partitions. The limit in
your case will be the 2 TB limit for MBR partitioned disks and
sometimes a limit of how large disks are supported by the BIOS,
which could be 128 GB for old LBA BIOS versions. FAT32 itself
is limited to 2^28 clusters, which means that even for common
cluster size 4 kB you already reach 1 TB in a single partition.
And clusters can be much larger than that, so your effective
limit is the 2 TB disk size limit of 512 byte per sector MBR.

That said, I recommend that you use LBA mode for partitioning,
so the partition type should be 0c FAT32 LBA, not 0b FAT32 CHS.

If you use extended partitions, you would use 0f with LBA instead
of 05 with CHS, but as you mention that you planned to use exactly
four partitions, you probably do not use extended partitions here.
Likewise, if you would use FAT16, type 06 is CHS, type 0e is LBA,
but FAT16 partitions can be at most 2 GB (in some cases 4 GB).

If you are using an older version of FDISK, it may have some type
of rounding error which could explain what you are seeing, but if
it just rounds the size to the next whole cylinder in CHS mode,
that would just be something common to do and not a real error.

However, if you get inconsistencies and the partitions do not  boot
or otherwise do not work properly, then that could be a real bug.

Regards, Eric
