Some burners just don't/didn't do a standard burn that every other drive can/could read, IMHO burning at max speed can make it worse. Since DVD burning became common, there's loads & loads of info on incompatibilities, mostly with brands of blanks but sometimes between burners & players. M圜E has loads of data/info in reviews & forums while Nero has a free tool to check a drive's real performance - the quality of the burns, rather than speed. I'd suspect the problem is the way the data was written or with one of the drives - hopefully the one you're trying to read with, but it could well have been the burner. Several years back there was talk of one layer on some DVDs going bad but the manufacturers fixed the problem & I haven't heard anything since. Tape & film degrade chemically/physically - old movie film is stored in vaults with a very heavily controlled environment. Hard drives have a commonly expected life-span of 2-5 years, because they're electro-mechanical they're subject to age-related failure (even if little used), & they do not like static electricity or rough handling. IMHO the best longevity theoretically would be on-line storage with a major company like Microsoft, as data's stored redundantly at more than one hidden & well-protected location. 3rd, lots of recovery apps specialize in CDs/DVDs, & many (most?) offer a trial that at least tells you what you'd recover. 2nd try it in as many drives as possible. isn't scratches, which can often be buffed/polished, & sometimes even coated with a polish.
When you can't read a disc, 1st make sure the prob. When you get a new burner, buy where you can return it, & try out freshly burned discs in as many players/drives as you can. Try not to buy a burner without checking out detailed tests, reviews etc. I keep a Win98SE VM just for that sort of thing. If you used one of the drag/drop type of apps to store data on CDs, maybe the same app installed in an old Windows version will work?.
To calm any rapid heartbeats that may have prompted, while there's nothing 100% fool-proof, I've had no problems reading well-stored CD R discs I burned in '95. CD’s (brand-label, not the low-price) have a proven lifecycle of max 4-5 year. I have about 100 CD’s filled with pics from 1999 – doesn’t matter what brand, I’ve got all kinds – and only 1 in 3 is still readable." The corollary being, if you don't back it up SOMEWHERE, I have to assume you don't want to keep that QuickBooks db, Outlook db, Doctoral dissertation.? Typical scenario: Q) "So why did the drive fail?" A) "First of all, this drive is seven years old.!" anyway, for any but the hardware-based pros (like dbtfish), I have a liking for R-studio's offerings.īut, yes, you can't beat gurus who delve into the platter-handling, controller-swapping, datatype-eyeballing fun of it all.īut, yes, you can't beat gurus who delve into the platter-handling, controller-swapping, datatype-eyeballing fun of it all. I tell my customers, in my shop, only backup what you want to keep. #14, donebythefish: Too many people have absolutely no clue that chaos happens, things fail. Besides, I absolutely agree: there are fine programs both free and donation-based (I LOVE PIRIFORM!) which recover many file types and still have the little edge which is required in recovering the unique formats/datatypes in pictures. Based on the comments, I won't be trying a program which the developers couldn't be bothered to fill out the the EULA nor actually show the program to English speakers to get feedback.
