Hi Everyone,
I'm currently imaging some optical media (mostly DVDs) and have found that for some Guymager is working fairly quickly but for others it will get to around 15% and kind of stall there. It will continue to pick up Bad sectors but it will take an extremely long time to do so. I left one going overnight and came back the next day to the elapsed time having taken over 24 hours, the progress still at 15%, about 20 more bad sectors, and the time remaining at 126+ hours.
I was wondering if anyone had every dealt with a similar issue and if so what was the solution or work-around.
Thank you!
Jennifer

Hi Jennifer,
I haven't had any hang-ups with Guymager, but we have decided to use ISOs for most optical media using dd or ddrescue. I have had pretty good success with the latter recovering bad sectors. ISOs make a full copy of most optical discs, except for audio CDs. For audio CDs, we have been using cdrdao, which produces four files, a BIN, TOC, CUE, and WAV. The CUE and WAV files can faithfully reproduce the CD if needed.
The disadvantage is that most of the reporting tools don't work on ISOs.
