I'm about to finish dumping all my discs but I have a few troublesome left. I have been using a Plextor PX-755SA with DIC and for all my SafeDisc protected discs the logs said "No unintentional C2 error". However, some of the discs have safedisc sectors that need to be reread, all with 312 bit errors. I suppose this is because a protected file wasn't detected on the safedisc sectors. Is the dump good even though the logs says "Done. See _c2Error.txt" instead of "No unintentional C2 error"?

On some discs I'm getting an error that says:

Creating .scm (LBA)   6108/335411
 LBA[006109, 0x017dd] Detected C2 error "00 F0 F0 F0 00 00 00 0F 0F 0F 00"
This error can't be fixed by plextor drive. Needs to dump it by non-plextor drive and replace it
 LBA[006109, 0x017dd] Detected C2 error 264 bit

Do I need another drive or is something wrong with the disc or DIC? If I need another drive, what should I get? Worth noting is that the error seems to occur in the safedisc area on some discs.
