Do you understand what RMA means? Return Merchandise Authorization (usually given before you send something in for warranty repairs.)
It is XBC that does not like the SATA pio, mainly because the way it is coded probably hasn't added support for it (yet?) - it is not the SATA pio drive that sucks in this case, and it's quite likely any SATA you'd use may well not work with XBC. You mention imgburn having issues - the specific one which you mention, failing part way through a burn but not at the layer break, is usually because of crap media - but when you mentioned issues with CDR as well I do know some early 2007 batches of 112 and 212 drives had issues which required Pio to fix them.
I am using a (Jan 2007) 212d right now on a SATA card (via 6421a) at the secondary port and I haven't had a single problem with it recognizing media and such (and is one of the best $35USD drives I've ever had no less), and even with the junkiest memorex dual layer I could find locally it hasn't failed part way through any burn for me.
You may want to look for bios updates for your PC, check the bios settings, try an alternate SATA plug on your mobo (so it isn't in one of the pairs with another drive preferably) and things like that before concluding the drive is the entire issue though.
