Two problems with using RW media in 'hard drive mode' Firstly, different software 'manages' the space using different 'format' and 'space' management The disc may look like a FAT partition, but that's because the software 'managing' the drive presents the data as a FAT partition to explorer (That's why Nero can have problems reading discs created by Roxio in 'packet mode'
Secondly, the discs usually have a life of 1000 rewrites - and every file you add, delete, or change usually involves a change to the space allocation information, or the directory information held on the disc, so writing 500 files individually can be expected to re-write the part of the disc containing the space allocation information. Think of a disc as an A4 notebook each page having a header, and the entire set of pages being accessed through an index held on the first few pages - It's up to the person starting to use the notebook how many pages they use for the index ( 1, 2, 4 - 6 whatever), and what they put into the headers on each page (3 - 4 digit page numbers decimal or binary), even how many lines are used for the header So - when the managing application reads the index, is the page number the first or last thing on the line and when you get to that page, does the information start on line 2, 3 4 or where?

The format allows one to create / delete / move files as one does on a hard drive. Which is why I just love using DVD+-RW format. Windows native build-in format for these disks wont allow you to delete 1 file out of many, but Nero INCD will, which is I believe is the source of all the confusion. INCD was working on the new puter, then for no apparent reason my old disks became full - ie I couldn't record nadir. On the old puter I had no problem with the same disk. My new machine is using the trial version 64-bit edition of XP - free to download, and otherwise working fairly well for a trial OS. I upgraded specifically to do this! Here is my system summary. OS Name Microsoft(R) Windows(R) XP Professional x64 Edition Optical drive : LITE-ON DVDRW SOHW-1693S Display Card : NVIDIA GeForce 7800 GT Motherboard : GA-K8N-SLi Chipset : nVidia nForce4 ICP Giga-Byte Technology nForce4 PCI to ISA Bridge Processor: AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ Any suggestions would be greatfully received.
