I have 3 drives on my desktop, samsung CD-RW and Samsung DVD-rom, i have a third external dvd+/-RW drive (gsa-h10n). I burned a multisession data disk on my external dvd drive. the first time i used the disk i burned 2 files. my internal (original) dvd drive read those 2 files. But then when i burned a third file using multisession , my internal drive would not read those files because they did not appear in the my computer window. they were only read by GSA-H10N. What can i do to make sure that the multisessions i create will be read by other dvd drives? program i used was nero 7, dvd media was playo (dont worry about the media) dvd+r and my pc is windows xp home edition.
