I think your drive is a 48x/32x/48x which means you can use High Speed (10x)
CDRW discs if you want. 

Staples is a "house" brand.  They will often be troublesome.  I am suggesting
you try a known brand (except Memorex) to be sure.  The standards for the major
brands a more rigid with there standards and thus reliable.  A "house" brand
came from the lowest bidder and perhaps the lowest quality.

I have a  Sony CRX216E CD-RW drive.  I bought a 10-pack of the Staples CD-RW disks for 10 bucks.  So you are saying that that are just not good enough for my drive?  I hope I can return the disks.

 

Try a major brand of CDRW disc (avoid Memorex) like TDK, Sony, etc.
Staples CDRW are an "off" brand and can be troublesome.  Purchase
a small quantity so as to not get stuck with too many.

What is the Brand and Model of the CDRW drive you have?

You were right - I used one of my TDK CD-R (up to 48X compatible) disks and was able to copy the files.  It also looks like I will be able to add to the disk as it is not full.  I am taking those non-functioning Staples disks back.

Thank you again.

Just a moment please.  You are confusing CDRW (rewritable) media with
CDR (write once) media.  Your 48x TDK disc is a CDR and the 1x-4x Staples
disc is a CDRW.  A CDRW disc can be erased.  A CDR disc cannot be erased.

CDRW discs are usually used with packet writing software.  That is, it can
be formated by the burning software then written to multiple times and
eventually erased and reused.  This has proven to be an unreliable media
for important files.

CDR discs are usually the most common and preferred media.  It can be
written to once, that is, it cannot be erased.  CDRs are low cost and
can be disposable because of that reason.  CDRs have also proven to be
a very reliable media for important files. 

A CDR can be written to multiple times with Multisession.  Multisession
allows files (sessions) to be added to the disc as long as the disc is
not closed.  The cost of not being able to use the whole disc until it
is finally closed.

Thank you Skybird for the info but I know the difference between CD-RW and CD-R.  I was just saying that I was able to copy my computer files to my CD-R (TDK).  I therefore am assuming nothing is wrong with my system and that you are right that the Staples CD-RW disks will not work with my system.
