unknown error -1309

I have a firewire/usb maxtor external 200 gig drive.

I partitioned the drive in 2 parts. First 20 gigs is MS-DOS formated. Second part is Mac HFS journaled.

Upon trying to copy a 7.62 gig file to the MS-DOS (FAT32) formated partition I recieve an error exactly when it hits the copy mark of 4 gigs transfered.

Unexpected error occurred
(Error code -1309)

This error code doesn't exist in the apple error codes. However the ones before it deal with formating errors. Is my mac including some kind of bug when I partition a MS-DOS format?

I've repaired the partition, erased the partition, erased the whole drive, reformated, ect. I can't get the file to transfer.

It copies fine to the Mac partition with no error. However the reason I need it to copy to a MS-DOS partition is to be able to hook the drive to a PC and transfer the file to my brothers PC who lives 4 hours away. I have no PC in my house.

Doesn't a PC only recognize a MS-DOS (FAT32) formatted drive?

I have no clue what else to trouble shoot or do.

Hi Adam,

FAT32 sets 4GB as the maximum file-size limit. This is why the copy is failing at 4GB.

PCs (from NT and Windows 2000 onwards I think) will also recognise NTFS but Mac OS X can read NTFS but not write to it.

Either you can try segmenting the file (using something like Stuffit) or if you're feeling brave, you can try installing MacFUSE.

I believe MacFUSE is still pre-release so beware of bugs. If it works, you can format your external drive as NTFS and have it mount on your Mac and PC. You will probably want to be comfortable in Terminal if you're going to try this though.
