I have both 1Click and Slysofts Clone DVD2 that i use with AnyDVD which are all always updated. The last couple of months I have noticed that some of my backups performed with 1Click have poorer Nero scan scores and often with bad sectors on these copies. When I use Nero’s quick scan feature the scores normally stay between 90 and 100 and do not show these errors, but when I use full scan mode and rescan the same DVD media previously done in quick scan mode many times the scores fall below 50 and sometimes down to zero and have several bad sectors on them. If I recopy the exact same DVD with Clone DVD2 the scores are far better and with no bad sectors. Please note that I copy the DVD to HD first using AnyDVD and Clone DVD2 with DVD9 media selected so I can copy the entire DVD to HD without compression, then I use 1Click or Clone DVD2 to to do the backup and compress as needed.
What gives ?
Does anyone have any rational explanation ? or ideas ?
