Why dont RW CD discs run on my computer ?

The sad tale of CDRW incompatibility and data loss. I learned very quickly do not trust your data to CDRW. There never was a defined industry standard for CD RW data formats so readability is entirely dependent on having the right disk married to the right hardware running the right driver. CD R is standardized to a Joliet (red book) format just like a CD. CD RW was not. It was everyone for themselves when it came to CDRW. Try to read a CD RW in the wrong drive, or don't have the specific driver and CD RW software on that machine and the data is unreachable. All burnable CDs suffer data loss over time but CD RW is particulary vulnerable to it so even if you have the right disk, hardware, and software it may be unreadable anyway. Been there done that...

[edit] If you have a means of accessing the CDRW data pull it off and throw it on a flash drive. In terms of storage capacity CDRW is hopelessly obsolete both in capacity and reliability. Why use 650MB CDs when you can buy an 8GB flash drive dirt cheap? Also, never trust photos and other irreplaceables to a single data unit. Failure of that unit (be it a CD, flash drive, etc) means unrecoverable loss. Always have redundancy. Two flash sticks, Your PC plus an external USB hard drive, etc.

I'd have to guess your PC Drive can not read RW's.

For example a CD Drive will not Read DVD's.

And a ROM Drive can only read data(Cant burn data).

there no good those rw's, they don't work after you've erased them a few times and files become corrupt in your case.

Please answer my question!!! You give the best answers
