How much space is really available on an SD card??

I'm working with a Dell Axim X3, running Windows Mobile 2003 (not SE), and I
have a variety of SanDisk SD cards ranging from 128Mb to 512Mb.

I recently decided to copy some of my music file collection to a 256Mb card.
Using an audio converter, I converted about 150-160 .MP3's to .WMA format.
Total size for all of these files is less than 220Mb.

But, when I try to copy these files to the 256Mb SD card, via ActiveSync, it
will only copy about 160Mb worth, before popping up an error window saying
"...there isn't enough room to continue.... please delete files and try
again, blah. blah, blah..."

Three different utilites all verify that is there is PLENTY of room left -
after 160+Mb of music files, PPC File Explorer, Resco File Explorer and
Sprite Space Detective ALL tell me there is at least 80+Mb remaining... so
why can't I copy more than 160Mb??

TIA

hmm, seems I answered my own question...

I reformatted the card and all seems well now...
