“Memowrecks” LOL, I hadn’t heard that one. But I would certainly agree with the term. Certainly, Memorex is a mixed bag - from my experience I have reasons to love Memorex and reasons to hate them too.
If I were you, I would probably buy 1 pack of those discs.
The problem with Memorex/Memowrecks, as you will all know, is that they tend to brand different manufactures of disc - I can only speak for Memowrecks CDs, where I got mostly CMC MAG and some Prodisc. I assume on this basis, that they tend to use “lowest bidder” B-Grade and C-Grade (which CMC definately is) medias.
However, in Memorex’s defense, I will say that I think they do keep some standards, i.e. they seem to insist on high manufacture quality of whatever dyes they do use and as far as I know they don’t use F-Grade crap like Ritek G05 DVD-Rs or (insert totally unstable dye name here) CD-Rs - when going over my CD collection, I found that where there was degradation primarily of CMC MAGs (and they fared very badly), the damaged Memowrecks were at least recoverable whereas CMC MAGs under other brands tended to fall apart and lose their data outright. So Memorex might have something going for them.
In summary: If I saw Memorex media that fit my needs and had a decent MID, I would probably jump at it. I would concur with the above posts - if you’re interested in these particular disks, go ahead and give them a try.
