Movie Junkie Posted March 1, 2006 Posted March 1, 2006 I need some help regarding a DVD-RW disc. To give some background...I copy my daily backups to this disc. Each backup goes to a folder named with the date (ex. 03.01.2006). Each folder contains about 290 MB of files. Every 10 days I use Dec to make an .ISO file and then write that file to a DVD-R disc (I do it that way so the original file dates are preserved. I then format the RW disc (full, not quick) and start again. Yesterday I got an error when Dec first accessed the disc. I checked the disc with DVDInfo Pro and found that the 3rd or 4th block was not readable. I still used Dec to make my .ISO I had it ignore 7 errors (all consectutive) right near the beginning of the read. I then copied all ten folders from the RW that has the error to my hard drive. I encountered no errors while copying those folders and their contents. My question is, can I assume that since no errors were encountered in the folder/file copy that the error on the disc was on a block that didn't have any information? If so then I believe that the .ISO file should contain valid information. Is that also correct.
LIGHTNING UK! Posted March 1, 2006 Posted March 1, 2006 In theory, yes. It could have corrupted the filesystem on the disc though so just be careful

Is there a way to tell if the file system is OK? There are thousands of files in each folder so it would be impossible to check them all.
LIGHTNING UK! Posted March 2, 2006 Posted March 2, 2006 All you could do is compare it against the original folder structure. Something like 'Beyond Compare' could do that with ease. Personally I'd just forget about that backup and carry on with the next one!
kevdriver Posted March 2, 2006 Posted March 2, 2006 MJ. I might be wrong LOL, but I ssem to remember a post back in DDSF days along this lines and there was a program that could check out your files for you............ damned if I can remember the name. I'll search through my puter for you and let you know.......
kevdriver Posted March 2, 2006 Posted March 2, 2006 cdcheck ? Yeah that might have been it LUK, it was back in DDSF days, I've done so many things with this puter since then probabley don't even have the app any more........ damn I hate it when I can't remember.....
kevdriver Posted March 2, 2006 Posted March 2, 2006 Hey Corny, how you been? going senile or just plain stupid........... LoL........ This is going to bug me the whole night now............ maybe a drink would help............
Movie Junkie Posted March 2, 2006 Author Posted March 2, 2006 Personally I'd just forget about that backup and carry on with the next one!That's exactly what I have done. I just started formatting the RW about 5 minutes ago. I did burn the .ISO file I made to a DVD-R just in case. Thanks for your help.

I've just downloaded the latest version. I'll give it a try on the DVD-R I burned the .ISO file to.
