I haven't had any problems with CD burning. For my own use I don't bother verifying the media and it hasn't been a problem for me. I would be surprised if DVDs were that much use. > As an aside, are flash devices any more reliable?

Has anyone here had problems with flash drives? I haven't. The only read errors I recall are the ones from when I used USB flash devices for the root and /var/cache/squid filesystems. I have started to use BTRFS for flash drives so silent data corruption at the storage layer will be apparent. In the past when using filesystems such as Ext3 it's possible that some files were silently corrupted. However I have used USB devices for large gzip compressed files and the fact that they could be decompressed is proof that they were OK. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
