File Size Limitation on UDF formatted CD-R/CD-RW

Hi All,

The last time I posted I got useful feedback, so here goes again. This problem has been consistent on two nearly-identical systems, so I do not think it is a 'system' problem. The systems are: XP1800/512mb DDR, Win XP Home, updated, 40gb ATA133 drives, and Yamaha 20-10-40 CDRW (8mb buffer) and LDG 32-10-40 (8mb buffer) on the other. Both use Roxio Easy CD Creator Deluxe, latest updates.

Here is the dilemma. The systems lock up and must be de-powered to reboot when copying a 93mb file to CD-R or CD-RW through copy/paste or drag/drop functions. The media have of course been udf formatted to allow this. The file has been copied and will show once the system is rebooted.

The file copies/pastes without problem across partitions on a hard drive, or within the same partition, or to an external IOMEGA Zip Drive.

I can copy the file to CD-RW if I use the Easy CD Creator engine and have not udf formatted the medium.

I can also copy/paste to udf-formatted medium if I have zipped the file down to 30mb or so (impractical for ongoing application).

Lastly, when copying the entire folder in which the file resides, all files 'before' this large file copy succesfully, as does this file (as above), BUT the system locks to the point where I have to cut the power to reboot.

This leaves me thinking there is some file size limitation on the UDF system, but this does not intuitively make sense to me.

I look forward to your input! Regards and thanks in advance.

P.S. If this was better under a different thread, I apologize. Was not quite sure where it fit!

 

 
This is certainly no solution, but mainly opining.

UDF is useless. Not only can most computers not read these CD's, but the formatting is time-consuming and support for this obsolete file system is waning fast.
The original purpose of "packet-writing" may have been to write files to CD immediately from small drives. But drives are much larger now.

With multi-session CD writing, you can accomplish the same end and still maintain a standard ISO format. Even XP's native burning software does this very efficiently.
