Writing this from the extremely miserable position of having 18 unreadable DVD-r’s (at 4.7gb each) I think I have entrusted data to a medium that is still in its infancy.
I was so careful to verify each disk after writing, and inserting each one several times (on 2 or 3 PC’s) to make sure they were readable, before deleting the source data from my hdd. Here I am 6 weeks later to find that the 18 previously working DVD-R’s are now completely unreadable - in any drive. I have wasted a long time with data recovery apps that claim to use smart tricks to read corrupted DVD’s but all to no avail. It seems the disks have just rotted away.
That 80gb of data was precious and will take an age to replace.
On reading lots of the posts in these forums, I can see now that the punter has to dabble in the black-art mumbo-jumbo of dyes, plastics, minerals, colours, coatings, firmware revisions, varying speeds etc before they may feel confident in trusting their archive material to DVD backup.
That’s way too much effort for me, I just want to buy a drive, a spindle of decent disks and back up some stuff. I love the ease of the big cheap backup that DVD offers but I will go back to trusty CDR’s, I have many disks that are sevral years old and they still read flawlessly.
If anyone knows a method for un-rotting these DVD’s I will be very grateful,
I doubt there’s any solution so I’ll drop DVD burning until next year when all the major flaws have been sorted.
