USB Flash Card 'Disk Full' erorr (no, its not full) [SOLVED]

Hi, when I mount my Compact Flash card from my USB reader and try to transfer a 10MB file it says the disk is full. On my windows box is says there is still 400MB free When I look at the properties in Konqueror it says:
Size (of the files on the card): 3.5GB
Free: 4.7MB out of 4.0GB

df -h says:
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 4.0G 4.0G 4.7M 100% /mnt/new

and dmesg says: SCSI device sdb: 8211168 512-byte hdwr sectors (4204 MB)

Really the card is only 4000MB not 4204MB. The filesystem is FAT32. Any one have any ideas how I can fix this? Thanks.

Try making a directory if there isn't already one.

On the flash card? Theres lots of directories.. What would that do?

I've had that happen before. If I just copied files to the root of the card without any subdirectories, it filled up really fast. It was just an idea, and apparently that's not your problem.

I think the problem is with how it is mounted. It should be only 4000MB instead of 4204MB I think.. Thanks for your input though.

bump - I've had this problem before on another computer but never figured out how to fix it. Surely someone here has had the problem and fixed it. Please?

So what happened really was when I mounted the drive, linux mounted it as if the drive was already 100% full when really there was some space left on it. Has this ever happened to anyone before? How did you fix it? Thanks.

Are you sure you haven't just run out of directory entries? The max # of files per directory in FAT filesystems is rather limited.

Theres less than 65535 files on the whole card. Also the directory names which are longer than DOS names still have on avg <500 files. Thx though.

Anyone? Any more ideas?

Ok so I fixed it. It seems the problem was, any time I deleted a file off of it in windows, the vfat driver didnt see that as free space. Merging winfstools and doing a fsck fixed the problem.
