Trying to back up a DVD that has quite a few faulty/failing sectors (probably due to deteriorating media; as there are very few very minor scrape/scratch marks on the disc).
Using IsoPuzzle in conjunction with AnyDVD. AnyDVD de-protects the disc and IsoPuzzle will (attempt to) copy all sectors, including faulty/failing ones.
I'm using several DVD writers for the process of backing up the disc, but one of the main ones I'm using is LG GH24NSD1.
In IsoPuzzle I've set the options "Cycle Tray" and "Allow Cooldown" to on (check marked) under "On Permanent Failure" box.
Every now and then IsoPuzzle will cycle the DVD writer tray which has the faulty/failing disc in it.
When the tray closes again, AnyDVD will re-read the protection on the disc and apply de-protection measures. Then the disc will become available to IsoPuzzle once again for continuing the reading procedure.
Most of the time there is no problem, but on odd occasion the system seems to hang/freeze while AnyDVD is (apparently) still trying to read the disc (after the tray closes) before passing it over to the system and onto IsoPuzzle. In this case I usually have to reset the computer by using the reset button on the case.
The issue seems to be a bit worse under Windows 7 (64-bit), but it also happens while running under Windows XP.
I think on one occasion (while running under Windows 7), the LG GH24NSD1 writer seemed to disappear from the list of drives available to the system, until I reset the system!? Also, on odd occasions, although not very recently, a message would sometimes appear saying to insert a disc when the disc had already been inserted!
Suspecting either a faulty drive, and/or faulty SATA cable, and/or faulty SATA port, and/or loose connection(s), I've made sure all power and data connections to/from the LG writer are secure. I've also changed to another SATA port on the motherboard. But I haven't (yet) tried another SATA cable as I don't (yet) have one spare.
No other programs are running in the background, such as anti-virus etc.
If the "Cycle Tray" and "Allow Cooldown" options are UNCHECKED in IsoPuzzle, then the tray will not cycle, and I've found that there is no problem and everything seems to work fine.
Using a Lite On iHAS124 DVD writer for reading instead of the LG writer, there haven't been any (obvious) issues so far. So this suggests a problem with the LG writer(?)
Anyone have similar problems? Ideas?
