Help, I'm trying to burn 4.7 GB DVD+R discs using Nero , on Windows XP Pro SP2, and I don't want to burn the whole DVD at once, I want to keep adding a few files at a time. The only problem (and it's a big one) is that I tried several times to create a second session and it always makes the first session hidden and invisible, so I lose access to that first set of data, why is this? I tried creating the disc as a DVD-ROM (ISO) or DVD-ROM (UDF), but both types give the same problem. I only see the latest session when I browse the burned DVD in Windows Explorer. What's up here? Have I lost that previous data for good (I hope not) or is there some program I can use to be able to access it? More to the point, how do I stop this happening again? I want to be able to add data whenever I like to the DVD so it fills up gradually and I can see all the files from the oldest to newest. I know this should be easy, but I can't figure out why it's going wrong. Help please!

Short explanation: this is expected behavior for multi‑session optical media — most operating systems (including Windows Explorer) read the volume recognition/volume descriptor information from the last session on the disc, and mount the filesystem described there. That makes the last session’s directory tree the one you see; earlier sessions can still be physically present but are not exposed by the normal mount. (dicom.nema.org)

If you need to recover the files from the older session, use a session‑aware tool that can enumerate and extract individual sessions. IsoBuster is designed for exactly this: open the disc in IsoBuster, expand the drive/tree to see the session nodes (or run its “scan for missing sessions” feature), then extract files from the session you want to your hard drive. If one optical drive doesn’t show the older sessions, try another drive — drive firmware/driver differences affect how sessions are presented. (isobuster.com)

To avoid the problem in future: burn using your burner’s explicit multisession workflow and use the same filesystem type/version for every session; don’t finalize/close the disc if you plan to append; test the disc in Explorer before deleting your source files. If you want true “copy/paste” behavior, use packet‑writing or rewritable media instead of write‑once discs. Nero documents the proper “start multisession / continue multisession” workflow for adding files later. (support.nero.com)

This explains the points already raised in the thread: ’s hardware caveat (firmware/drive differences), ’s pointer toward IsoBuster as a recovery option, and ’s observation that Nero’s multisession approach will work when the correct multisession workflow is used. If IsoBuster cannot find earlier sessions on any drive, the original session descriptors may have been overwritten and recovery may require professional services.

have thist prob appered for the first time? coz some of DVD drive doesn't support multisectioning.

Correct, or rather I never tried adding files incrementally before, I was always burning a full DVD at once. I just tried burning 2 DVDs and both times (once as a UDF disc and once as a DVD-ROM) the 1st session was no longer visible after writing the 2nd session. I'm using the DVD drive in my handbag-sized computer, Sony Vaio VGN-S3XP model, about 1 year old, which has a Mat-Shit-A brand DVD burner, if that's any help. I hope that Shita is not one of those that doesn't support multisectioning, otherwise I will remove it and cut it up into multiple sections... Thanks for your advice!

Ah, another thing I'd like to know is if this drive doesn't support multisessions, can I access the data I already wrote to those 2 DVDs by using a different DVD burner (or player) that does support it? I wrote some rather important data to one of the DVDs and I deleted it from my hard drive, and now that data is in the 1st session and I can't get at that data.

the answer is no, it will see only the last modification unfortunately.

You can see the data that was burned into a the DVD in the first session by using a free program called isobuster. Search google for 'isobuster' and u shud find it...
