RE: [chat] CD-R media

["Minh Van Le" <mvanle@xxxxxxxxxxxxxx>]

Out of personal preference based on trust and experience, I backup important
data on to TDK CDs. I have TDK CDs created since 1998 which are still
usable. These days I just use any brand including no-brands and make regular
backups and put my faith in CD care rather than quality, except when backing
up really important stuff in which case I use TDK.

In my experience CDs don't wear out that fast, if at all. I keep my CDs in a
dry and cool place away from sunlight. Don't drop, bend, or scratch either
side of the CD. Most CDs develop faint harmless scratches when used
normally, but if you use a CD regularly, you may consider backing up your
backup CDs and set them aside for emergency-only use. This is what I do with
original music CDs.

I also notice that when burning CDs using XCDRoaster, there're grade
indicators like A+, A-, B-, C etc which seem to suggest the quality of
media. Not sure what these grades mean in relation to quality of
film/chemicals, scratch resistance, CD life etc.

Some CDs with read problems read better in another, different brand CDROM
drive and/or OS.

IMO at 15 - 30c / 700mb CDs are a cheap and reliable backup medium. Good
enough for PC host backups.

Hi All,

	Am wondering what other users experiences are with CD-R media
	and long term data integrity ?

	I have some 2-3 yr old CD-Rs containing data but have too many
	read errors to be of any use now (and some totally unreadable).

	How does one determine what CD-R is going to last beyond a couple
	of years ? One wonders if it is worth considering CD-R/CD-RW as
	a worthwhile media for backups ?

	Thanks.

Regards,
Raj
