Well ... recordable optical discs might not crash ... instead they "rust".
Tried reading some cdr/ dvdr from 5 years ago? Or from 10 or 15.
These things are the worst medium for backups. Maybe appart from floppys.
Don't use them for anything that is important or should still be ther in >2a.
Harddrives are much more reliable and cheaper at the same time.
Besides copying from them wold hardly be faster than reripping.
And why as zip? If you simply burn the image normally you could play them too.
Yeah dvd-r discs do rot given enough time. But if one disc becomes unreadable its a lot easier to replace
then a 1TB hard drive that fails. I have cd-rs from 1998 and dvd-rs from 2004 and they all still work with out errors.
I guess it all depends on media quality and storage. I use Verbatim dvd-r's and Memorex dvd+r DL. Verbatim dvd-r
are rated First class manufactured media (MCC03RG20 factory ID). by zips i ment it as a way of archiving them. when games are scrubbed they become smaller when rared/zipped. All games i download get archived in rars/zips and placed on dvd-r.
I currently have 610 wii games archived on 200 dvd-r discs and a list to tell me what disc each game is on.
Hard drives are cheaper but when they fail they take everything with them.
