Erasing a CD-RW disc

[dodecahedron]

i use a few different programs to erase my CDRW discs:
Nero, burnatonce, today tried CDSpeed.

i was wondering if it makes any difference what program you use to erase a CDRW? is it possible they don't do it exactly the same? what effect can this have on the disc or on data subsequently burned to it?

i timed it, Nero took about 8:20 min, burnatonce and CDSpeed took about 8 min. why does Nero take longer?
[all were on the same drive of course - my Plextor 40x12x40x, but different discs. but all were Verbatim DLP HiSpeed (4x-10x) which have only been used once to burn roughly 3MB of data. it was a Full erase done at maximum (12x) speed]

No it does not make dfference. Erasing, that's a simple thing. Writting zeros to disc, am I right?

I had some problems erasing a DVD+RW a while ago (see this post at CDFreaks). Nero and CD-Speed didn't work at the time, though the bug was fixed later. DVDInfoPro did the trick on that one. It also has an option for a "DC-erase" (or something similar- I don't have the program anymore) that supposedly restores a RW to a "virgin" state on some drives.

So ther is some variation on how a program erases, although I expect it's just a MMC command that is issued with more or less overhead.
