I'm doing a favour for a customer of my workplace (no money is being exchanged for this). Basically, the client runs a Recording Studio, and backups are all done on Mitsui's Gold CD-Rs. Now, 4 years ago, for whatever reason (possibly poor availability?) he used some Mitsui Silver CD-Rs for some of his archives. He now needs the data on these discs, and finds that they do not work at all! (for those interested, since these discs are over 4 years old, they were made by Mitsui BEFORE they were bought out and turned to crap by C.S.I. !!!, so there is no reason I can think of for this to happen!). So I'm trying to recover as much data from them as possible.
Right now I have them plunked in my Plextor Premium CD-RW drive, but there are still LOT'S of read errors, and I'm thinking I won't get any intelligible data.
I'm currently running one of the four discs on the Plextor Premium with Alcohol 120% set to retry LOT'S of times, and to read it at 1x if possible. I've also got it using Advanced Data Detection. I also have it set to recover the best bytes from each sector.
Does anyone have any suggestions on what could be done better in order to recover more data?
Your comments are appreciated!!
