Parted Bug: There are no possible configurations for this fat type

[Martin Steigerwald]

Hello,

Today I tried to reduce the size of a FAT 16 data partition for Windows to 
make room to add another Windows partition. The partition is located at the 
send of a 40 GB drive (see below for further information on the partition 
layout after I reduced the size of the FAT 16 partition... before that it 
ended at the end of the harddisk).

I typed 

resize 9 34389 36000

and it reported me that I got a bug I shall report to address@hidden:

"There are no possible configurations for this fat type" (FAT16 the partition 
used)

I say "Ignore"... now comes:

"Warning: Filesystem doesn't have expected size for Windows to like it. 
Clustesize is 64K (536890031K expected), number of clusters is 60490 
(1073938162 expected); size of FATs is 237 sectors (1 expected).

I say "Ignore" again... parted offers me to convert the partition to FAT32 
which I accept. And then it moves data and mount the partition again under 
Linux and it seems to be okay.

I did not yet test with Windows - and currently I do not really care - but 
before my change this partition definately worked OK under Windows... so I am 
not quite sure what the "doesn't have expected size message is all about".

Here is parted 1.6.2 output after another resize to 35500 since I could use 
really some room for Linux here ;-).

partition 8 is a Amithlon virtual harddisk partition (partition type $76) it 
contains a Amiga Rigid Disk Block (RDB) and partitions that Amithlon makes 
accessible to the Amiga system. My Debian Linux is on the partition 6 
(ext3fs). 

Some further info on my machine that might be useful. When you need anything 
else, please tell me. I am on holidays from 26 July to 19 August 2002 and 
will not be at this place where I can access this computer after 18:00 today 
(24-7-2002). I hope this bug report is helpful.:
