Re: Problem with minimum partition sizes

Hi,
Afaik i'm the only gparted developer (note that you're actually asking on
the wrong list since gparted != (lib)parted ) and the the min. size for
fat filesystems have always been 32/256 MB, so i really don't understand
the 8Mb limit you are mentioning.

Unfortunately I'm not too aware of the internals and who works on what .. I can however say that as a result of this issue, I'm unable to use "gparted" .. ;-)

Unless I'm losing my marbles, gparted 0.0.8 tells me that the min partition size for dos fs' is 8Mb .. and 0.0.9-pre is larger.

seems sensible etc.. Please file a bug
(http://gparted.sourceforge.net/bugs.php) about this, with your arguments,

Will do.

PS. Andrew, could you please elaborate a bit about why a partition should
be rounded to cylinderboundaries? I've always been told this is a good
thing, but i don't know exactly why ;)  thanks!

Just one point - if you *need* a 4Mb partition, reasons why it's "good" to round are completely immaterial .. (!)

Gareth.
