For some reason I have a program on CD that cannot be read completely, I thought once things are on a CD it was forever?
My desktop has 2 cd drives, one of them will not even recognize the cd is in there, the same with my laptop.
the other cd/dvd drive/recorder etc will read only parts of the cd "sometimes" and not other times, let me add that all other cd's work in all drives,
except this one, it is a copy and had a home made label on it, I thought that might make a difference so I removed it and the glue with alcohol, at first it seemed like it worked.
Can a cd just lose its content? how? it doesn't make any sense to me.
Burned copies of CDs are notorious for inconsistent reading in different drives. It makes a difference if they are CD-R, CD+R media, brand of media, the drive they were burned in, the speed in which they were burned, etc. etc. Also, if it was CD-RW media, those do not have the longevity that just plain CD-/+R media does. The fact that they are eraseable and re-writeable seems to make them less stable than the write only media.
I have had a couple cases where I burned data to a CD and checked it, then later had trouble reading it, even on the same drive it was burned in.
I now only use brand name CDs (Memorex or TDK, had trouble with Sony) and burn at low speeds, usually no faster than 4X. If I really want to be relatively confident of the result, I burn at 1 or 2X speed. Even then it is not a guarantee it will read reliably in someone else's drive.
