My first BUs went fine, then last night I went to do a new BU on my HP
9510 using old BE4.5 CD-RW's. All seemed to go well (it had to reformat
- recover - medium first). THEN - at what appeared to be the end of
disk 1 BE quit and wouldn't span to the next disk.

I finally gave up and did the BU onto 2 CDRs and all went well.

Any idea why BE 4.5 won't use old CD-RW's, nut will use new ones?
