DVD Writers and excessive heat??? Please read.

[Bricktop]

Hello all.
Heres the situation....
I have a disc that is badly damaged, scratched thanks to a friends dvd player which scored a nice ring around it when i lent it to him. So i decide to try and retrieve the data by extracting what i could with dvd decrypter then use isobuster to pull out the stubbon, damaged areas. I put the disc in my burner and selected the appropriate problem files with isobuster and left it running while i went out for a couple of hours.
So far so good you say...but on my return, isobuster had only moved 3% into the file so i closed it down and removed the disc. The disc came out PIPING HOT. I immediately realised i could have damaged the drive so i tried burning a cd with it. Power calibration error said nero. So i tried a dvd burn. Power calibration error complained nero. Tried another burning application (record now max). Disc read error was the warning this time.
I burned fine with this drive before my isobuster session and now it wont burn a thing at any speed. So i left it for a few hours in the hope it would cool down and play ball again.....lo and behold it worked and touch wood has been working ok since.
So if your trying to extract damaged files with isobuster, i would limit the session to 20 mins max to save excess heat build up and wear on your dvd burner.
Cheers.

Which is why many advocate using a DVD-ROM drive for reading, and not your burner.

I had a situation some years ago now where I was converting my 120 CDs to MP3. Naturally I wanted to do it in as shorter time as possible so I had my CD-ROM going flat stick for about 12 hours. I had all the error checking and things checked in CDEX, and set one last one off before I went to bed. Sure enough, the CD-ROM choked on a scratch or imperfection in the disc, and sat there trying to read the same sector all night. When I woke up, my CD-ROM was buggered. Luckily it was still under warranty and NEC reported that it was the first time they had seen a melted laser in their CD-ROMs, and replaced it for free. Lucky me !

Yes mate i do have a rom drive also but the difference in how the 2 read is staggering. The burner is far superior at reading damaged sectors, i dont know why. My guess is the laser is more refined???
