PC Exchange: Copying Large DOS Files Issue

I have a Power Macintosh 6400/200 running Mac OS 8.0 which ships with PC Exchange 2.1.1. I have attached an Iomega Jaz drive to my Power Macintosh. After inserting a Jaz disk that was previously formatted on a PC under Windows 95, the disk mounts in the Finder correctly.

The PC formatted Jaz disk shows that is has 1,020.6 MB of storage space available. I'm trying to copy a very large document that is larger than 510 MB in size to the Jaz disk from my internal hard drive. I keep getting an error message that says, "The file 'xxxxxx' couldn't be written, because the disk is full. Do you want to continue copying?". Clicking continue does not work. I have found that any file that is less than 510 MB copies normally. Is this problem with the file I'm using?

PC Exchange 2.1.1 and earlier has a problem when trying to copy a file that is approximately half the size of the available free space or larger to a DOS formatted volume. Currently, the only work around is to copy files that are smaller than half the size of the available free space of the DOS formatted volume. In some cases, it may be necessary to segment a very large file into smaller pieces.

Apple is aware of the issue and is working to correct this problem in future versions of PC Exchange and the Mac OS.
