CD-R disks
 

Is there any way to delete things on CD-R disks at all?

no

Double no

Absolutely not

Quad no.

Buy CD RWs.

Unless you're making CD mixes, in which case it's safer to use CD Rs (more players support them).

Don't buy CD-RWs because they are pretty pointless. You can only write on them a few times before you have to throw them away anyways so you're better off getting the cheaper CD-Rs. If you are transferring data that much that you need CD-RWs then get a flash drive. More storage and better read/write speeds.

What is this? 2001?! :D

I have 3 RW's that i bought 2 years ago and I'm still using them.

But yeah, get a flash drive. A 512 MB or a 1 Gig preferably.

RWs last way longer than that.

I'm not saying they only last 3-4 times, so maybe few wasn't the right word choice, but depending on the size and frequent usage, CD-RWs will only work well for a shorter time then expected. You're still better off with a flash drive and CD-Rs.

I agree on bot h counts, just disagreed with the math.

There was a brief period during which RWs were actually the best option. But Flash tech has become so much cheaper, there's no real point.
