[QUOTE=meeshu;2782661]Trying to recover data from a failing DVD using IsoPuzzle and AnyDVD
The LG and Samsung DVD writers are managing to recover some data, but slowly. The Lite-On DVD writers are recovering data just a bit faster, but still relatively slowly.[/QUOTE]
Of the many drives I’ve tested only one overlaps with your list. That’s iHAS324 (specifically iHAS324B) and it wasn’t anything special.
[QUOTE=meeshu;2782661]There are currently about 115,000 “missing sectors” on the failing DVD as reported by IsoPuzzle. At the current rate of data recovery, it will take perhaps at least two or three weeks to recover most or all of the data!?[/QUOTE]
It’s extremely unlikely that more than a handful of sectors (or really 16-sector 32KB blocks) will eventually be read of those “missing” sectors if a full attempt has already been made to read the disc to the end with a program like IsoPuzzle. I would stop now and wait until you get a better drive in order to spare both the disc and the drives from additional unnecessary use.
[QUOTE=meeshu;2782661]Ideally I would like to recover data faster. According to various online sources, I understand that (some) Blu-Ray readers/writers may be better at reading/recovering data from bad DVD’s than (some) DVD writers can.[/QUOTE]
This is true in my experience. It will depend on what’s wrong with the disc though. Is it a pressed disc that’s scratched, a bad burned disc in good shape, a bad burned disc with scratches, or a good burned disc with scratches?
[QUOTE=meeshu;2782661]If so, what specific makes/models of currently available Blu-Ray readers/writers are known to be better at data recovery?[/QUOTE]
For practical purposes, “currently available” needs to include discontinued models that can be purchased used or new on eBay or Amazon. My best experience with scratched DVDs has been with Panasonic UJ8E1 drives (which are also pretty good for reading bad CDs). It’s a laptop drive so you may need a USB-to-SATA adapter cable if you don’t have a laptop to put it in.
For bad DVD burns (ideally not scratched) of various types I’ve had very good experiences with the following drives:
- Lite-On iHBS112 (SATA internal; alternate model number is DH12B2SH)
- LG BH20N (SATA internal)
- Toshiba SD-H802A (IDE HD-DVD drive; USB external model is Microsoft Xbox 360 HD-DVD drive)
- LG GGC-H20N (SATA internal)
- LG GGW-H20N (SATA internal; USB external model is Buffalo BRHC-6316U2-US)
In another thread Samsung SH-216BB is recommended. I found that it was pretty good, but not great. Of course, each individual unit varies a bit. In my testing, different Lite-On drives of the same model weren’t consistently great. The Toshiba ones were a bit mixed too. The LG ones all seemed to work equally well.
[QUOTE=meeshu;2782661]And/or are there any other known currently available DVD readers/writers that are good at data recovery?[/QUOTE]
The Panasonic UJ8E1 laptop drive that I mentioned is a DVD drive. There were some other laptop drives that were good but not as good (UJ8C1, UJ8B1, AD-7561S). The best desktop DVD drive that I tested was an LG GWA-4165B. That’s an old IDE drive though.
All of the drive models I’ve tested are from or were introduced in 2013 or earlier, so there’s nothing I can recommend as far as the very latest models. I can say that while the ‘20’ LG models that I listed were very good the later BH30N was lousy. I don’t know what that means, if anything, regarding even newer LG drives, but it may be worth keeping in mind. As far as I know Lite-On stopped making Blu-Ray drives (except for Xbox One drives) after the iHBS112/212/312. Panasonic’s recent desktop DVD drives may not be great since the SW820 was pretty lousy for bad DVDs (plus it was insanely loud). The newer Panasonic laptop DVD drives that I’ve tested have been disappointing as well. Pioneer’s Blu-Ray drives that I’ve tested (BDR-101A, 202, 206, and 208) don’t work well for reading bad DVDs.
Hopefully that gives you a place to start at least.
