I’m a little stumped, so I’m hoping someone can lend some guidance. I’ve been trying to burn some files (*.ogm files to be precise) to a DVD+R and having a bit of a problem with CRC errors. I can’t burn 4 of these ogm files, everytime I attempt to burn them to a DVD and then check the files after burning (checking MD5 hashes to ensure they burned properly) the same 4 files fail with CRC errors when copying them back to the HD to calculate the hashes (I’ve found that copying and then calculating hashes is actually quicker, so I do it that way). I’m starting to get a bit frustrated as I’ve thrown 6 DVD+R’s at the problem thinking it was just defects in the disc or problems with background processes at the time of burning. All other DVD burns work fine, I can burn any other files to DVD’s with no problems. Here’s my setup/media:
OS: Windows XP
Burning Program: Nero 18.104.22.168
Burner: Liteon 401S@811S HSOR patched with the omnipatcher for faster reads (not patched for faster writes though)
Media #1: RICOHJPN01 (4 of the 6 discs)
Media #2: YUDEN000T02 (2 of the 6 discs)
Kprobe scans have been good PI ~ 70 or less, PI ~ 4 or less (well on the RICOHJPN01’s at least the TY’s haven’t been doing as well in this drive… strange) for all discs aside from these ones (I haven’t run Kprobe’s on them).
I’m guessing it’s going to be something with the files as I doubt it’s bad media, or problems with firmware/drive as most of my burns are coming out really nice. I’ve check for fragmentation the drive is less than 10% and the files in question have no noticeable fragmentation (should I defrag anyways, just in case?). I’ve rebooted in between burns to ensure that no other processes are using those files. I’ve also shutdown as many background processes as possible to eliminate problems they may cause. Any thoughts as to why specific files would not burn properly? Would copying them to a different location on the hard drive help (incase of bad sectors, I recently did a chkdsk and it didn’t report any errors). I’ve checked for viruses/spyware recently, just in case (last 2 days). Any thoughts or ideas would be appreciated.
