40 gigs somehow = only 4...

I made a 40 gig ext3 partition on my slave hdd
when I went to dump some files onto it I ran out of space at 4 gigs, fdisk still shows the partition at 40 gigs but df shows only 4 gigs
I have no idea where my 36 gigs went

I think you need to create an extended partition in order to support such a large partition size. People usually make the 4th partition extended because there is a limit of only 4 primary partitions. But if you want just one big partition then you can make the 1st partition extended and the 2nd partition can scarf up the rest of your disk.

Hmmmm

How did you dump the files into it ?

Did you use something like
dd if=/dev/hdxx of=/hdxx
???

I recently copied a 3 GB-partition to a 20 GB-partition via
the mentioned dd-command.

After copying some other files i ran out of space on the 20 GB-partition as the used space exceeded 3 GB. fdisk reported a size of 20 GB, so i should have 17 GB left. So somehow the 3 Gigs-limit also was transferred to the 20-GB-partition.

Dunno if this is a feature or a bug with th dd-command.
Maybe dd should not be used in that way if the partitions dont have exactly the same size.

It's definitely not a bug in dd, that's what dd is supposed to do (copy exactly input to output). You could try to resize your filesystem with resize2fs or resizereiserfs to use the additional space on the partition.
