I just tried out my new R-09 for the first time yesterday, and found it worked great! I actually formatted (or at least it appears that I did) a 4GB Transcend card in the R-09. It just kept saying it was processing, so after a while I assumed that I had messed it up, but after stopping it, taking the card out, trying to format it on my computer (with no success), I put it back in, hit record, and it worked fine. I am still not entirely sure what I did, but everything seems to be fine...
The show recorded great, and transferred over to my computer with no problem at all. Go figure.
I will have another go with it at a show tonight and see what happens!
