I have about 200 DVDs, most 10 years old. Probably 1/4 is unreadable by now: MacOS does not recognise the disk when inserted (oddly enough, much older CDs still are).
The data is not terrible valuable and probably already mostly stored elsewhere, but I'd like to give it a try. Is there hope for ddrascue? I've had mixed results in the past. Are there better alternatives?
- e12e 8y ago> MacOS does not recognise the disk when inserted (oddly enough, much older CDs still are). Difference in data density? A cd stores ~800mb, a DVD ~4700mb.
- anticensor 8y agoCD stores 650MB in standard format. 800MB is overburn.
- tambourine_man 8y agoCould be, but I’m also betting on media quality. First recordable CDs were expensive. Those last DVDs I bough were dirt cheap
- topspin 8y agoIf you take away one thing from the article it is this; try different readers. Some readers perform far better than others. I have one 'magic' DVD reader that will overcome damage that makes most other drives choke with errors, and the result is usually a flawless rip.
- voltagex_ 8y agoAVSForum, Doom9, Redump and Hydrogenaudio are all good places to find out about these drives, too.
- tambourine_man 8y agoYeah, an old iMac is the one that reads most them. But I was hoping for something better.
