Is there a specific number of times a DVD+RW can be reused?

I saved a one page document onto a DVD+RW (first time using)and it took up
the whole 4.7 GB. Then erased it and saved a large Folder (~399MB)
containing many Files from my other computer. Checked it and all OK. Then
elected to add more files from old computer but apparently disk full.
Thinking I did something wrong, I erased again and started all over. This
time saved all the files of interest but when I subsequently tried to use
the disk, a message box appeared saying something to the effect unable to
read the disk and/or disk is corrupt.

They claim about a thousand times.

If you got this info from Explorer, be aware that DVDs and CDs
use a different file system. Most of the time, any file of any size will
cause Explorer to report the disk as being full.

Which program reported this?

My thought is that all of these changes, etc., have somehow destroyed the
file system on the disk. Perhaps you can regain the disk with a full
format. As cheap as disks are, it hardly seems worth the bother.

They are *supposed* to be rewritable a whole load of times. In real life,
though, you do get discs that work better as coasters .. which means if you
depend on DVD-R or DVD RW etc. for backup, it might be smart to burn more
than one backup copy.
