You have a known good source of photos but when the dvd is near full it fails ?
You keep writing to the dvd over multiple sessions and in the last session it all went tits up ?
That sums it up perfectly.
All seemed to go well until the last folder was copped. About five copy sessions with testing in between. What I didn't do was to eject the disc between sessions. This puts up a box with words to the effect, 'hang on a moment, disc is being prepared so that it can be read on other computers.'
I'd be sorry to hear the the multi-use of a DVD (I'm on W7 BTW, if that's different.) ...sorry to hear that I can't do this. Sorting the photos is greatly helped by not being bound to a single session. Sure, I can used the HD first, but that seems like cheating.
I talked on other threads in the last few days about the apparent loss of photos, but I seem to have millions on the new HD, and the only problem is that there not sorted as well as the lost data. So, no real problem.
However...I was just about to download Ccleaner for my Laptop, and I noticed they do a file recover utility. May give that a go just for fun. The OS on the old drive is really @$^@^ed. And much of the data is unreadable, so I'm assuming a ceremonial dumping of the drive as the only safe long term procedure.
