Hi there, I've successfully burnt data (4 GB, around 10000 files) to a DVD. I saw that all the files have been burnt to DVD with exact size. However, I couldn't read some of the files (corrupted ?) and this happened randomly (i.e. I burnt another ten DVDs with the same contents and the corruptions happened on different files).
Here is the error message while copying the file (linux): cd:reading /media/cdrecorder1/ares_apca_pref_0505202021111.zip Buffer I/O error. and the message log output the following messages: May 13 12:10:59 kernel: scsi6: ERROR on channel 0, id 0, lun 0, CDB: Read (10) 00 00 05 71 15 00 00 23 00 May 13 12:10:59 kernel: Current sr3: sense key Medium Error May 13 12:10:59 kernel: Additional sense: Unrecovered read error May 13 12:10:59 kernel: end_request: I/O error, dev sr3, sector 1426516 May 13 12:10:59 kernel: Buffer I/O error on device sr3, logical block 356629 If I copy the file in a windows box it gives me a "cyclic redundancy error" message. Below is the configuration of software and OS used: 1. OS Linux 2.6.9-5.0.5.ELsmp 2. growisofs - version 5.21 3. mkisofs 2.01 (i686-pc-linux-gnu) 4. burner - SONY DRU-700A (with latest firmware upgrade) Following is the growisofs command used: /usr/local/bin/growisofs -use-the-force-luke -v -iso-level 2 -pad -Z $g_device -R -J $buffer_path I wonder if anyone out there can point me out what's going wrong here.
