RSC32 works with files regardless if they readable or unreadable. –rt and –rrr would work with unreadable files without additional issues.
will it just skip the broken file or will it try to get as much of it like possible (in case of HD sector fault) ?
Say, you already have RAID-array of several HDDs. Why you nevertheless need a file RAID?
I dont have a hard raid (yet). I messed around with Freenas but found it to be unflexible. Changing size after setup is a problem, you need many disks etc. Also a NAS is slow and not very cost effectiv (if it runs 24/7 you could buy at least one 3TB drive every year ...) so thats how I came to this forum.
Well, I have written you a proggie which can modify files by writing random bursts into them. But this NOT a copier, it is really a patcher!!! =)) Keep your origins in a safe place =))
Usage: FileName BurstNumber BurstLength
Say 1000 512 will write randomly 1000 packets of 512 bytes each of trash
Of course, RSC32 could not repair anything if Number of bursts will be greater than Number of recovery blocks.=))
:) so we have 2 proggies now ! I attached mine. it will copy the file and put bursts in it.
persicum, I learned quite something about redundancy in the last few days and the more I dig into the more I learn about the powers of rsc32. I still have the feeling that I am missing a lot of information though: I am a little embarrassed but is there a manual for rsc32 ? I found the options.txt but no explanation for the options ... I read through the forum (not all of it though and tried
to read into Reed-Solomon codes at Wikipedia but dont understand a thing...). Any chances that there will be help.txt for rsc32 or a sticky or faq ?
