Watch out for the Sony CD-RW 16xx (4 digit) drives. Yes, once you have it working it's a nice drive.. it should have a nice blue faceplate that looks good in a firewire case, but beware the pitfalls. Check Sony's storage support site.
http://sony.storagesupport.com/cdrw/crx1600la2dwn.htm The Firmware upgrade is recommended for "...Mac G-4 detection issues",(unless the drive already has the latest--a crap shoot) yet it can only be installed from a PC. Nice. And Typical of Sony, except I'm surprized they mention the Mac.
I just went through it with The CRX1611, I bought 5 of them bare for $75 each, and was scratching around for software that would actually work with them, and found that Toast 5.0.1 was the ONLY thing I owned that would work with the drive. Disk Burner wouldn't touch it. iTunes? Forget about it. Nor would any version of Toast prior to Titanium 5.0.1. It wouldn't even show up in the Apple system profiler.
I managed to sell the 5 drives I got, repackaged as Firewire externals, and set up the buyer (thankfully a Mac user) with Toast Titanium.
Ironically the only thing that will make this drive work on the PC is Sony's CD Extreme software-- even the latest, EasyCD Creator 5 won't go near it!
After the whole transaction, I understand why I found them so cheap, and why the re-seller I got them from didn't even know what software worked with them and had none to sell me... nothing he had would work with this drive!
I've learned from this and other experiences that Sony actually has a horrible track record for product support, and a care-less attitude about Mac support for what should be cross platform equipment, so beware them! Buying a digital camera, comp peripheral, Handheld Palm device, etc. is a minefeild of Mac support.. some items work fine with Macs and Sony supports them like a normal company, others, even in a seemingly direct numbered product line DON'T work with Mac, and Sony's attitude is--"oh well, OR-- Mac users must pay MORE for special software that makes this work!"
The 5 CRX 1611's I bought...? That's the LAST Sony headache I go through! I've learned my lesson!
In short, yeah I'd avoid Sony (16xx)drives and thier crappy software, and go with a drive with clear all around Mac support and Toast software.
