use what works and makes the most sense for you.i HAVE had cdrws and cdrs fail.since then i always use error checking and in the 4-5000 cds that i have burned in the last year(i do some duplication for a few clients)i haven't had any problems with failure since that i know of.most batches of cdrs that i buy are fine(i buy 500 at a time),but i have had occasional batches that leave 10-20%(!) of the discs on the "reject" pile.

i'm sure that there are ultra premium discs that gaurantee 100% good discs,but at a buck a disc,additional hds start to look good to me.and i'm not even mentioning the hassle of backing up 10 projects to cd,a project that can take all night.....

Use DVD+R

Using Winzip & WInrar buys some better error correction built into the process, I'm not sure if it works with the compression disabled however.

Also I find Winrar easier to make split files from, for zips that are split using pkzip (32bit) from command line seems easier than winzip, though honestly I've not tried with winzip since v7.

WinRAR totally rules for everything pretty much.. I particularly love being able to extract multiple archives. It supports way more formats than WinZip, and the compression is really excellent.

peace

Interesting. I do small-run duplication in my studio too but I've never gotten that many rejects. Maybe one out 500 pieces or something like that. That seems like a reasonable reject rate to me. If I was seeing 10%, I'd change brands. I've bought just about every noname brand there is. I usually buy unbranded (silver on both sides).

Here in the Chicago area, I can get CDR's and those slimline cases for free. That's right - free! Our local OfficeMax store runs monthly specials and they offer 100 CDR's and 100 slimline cases for free after rebate. Technically, I haven't paid for CDR's and cases in over a year. I think the brand is Imation or something like that.

So I'm not really too fussy about the brand. I get whatever is on sale or free Even with these freebee brands, I don't recall any rejects except once or twice a year maybe I'll see one.

the encoding process carries a danger of producing errors in itself, specially on large files. If something goes wrong with an encoded file there's not a chance at all to manually repair it.
If the files are just split one might at least try to 'cure' with fake values.
Of course this does only apply to pure data files like .wav .txt etc (if the error occurs in certain parts) and will be of no big use on .mp3 .jpg and the like.
But fortunately I haven't had any opportunity to try it out - and I'm not keen on getting one

Imho a good backup media is a used, but not completely worn out harddisk.
Those tend to get a little noisy due to mechanics and are usually not that fast as current models, so they don't get useless.

cheers, Tom

krizrox,that's a good deal.i usually use ritek.i only have problems with discs on really big cds.the rejects DO usually play,but they ARE NOT perfect copies(cd players do error correction...),so the computer rejects them.for long term data storage,i don't see how any less of a standard could be acceptable.(i don't hate anyone for using cdrs!i have a number of cdr backups here.... )

the old hd trick is a good one.....

for your ghost images of course,this discussion is moot.
