I use my Boss BR1600 all the time. Mostly as a phantom power unit for my mic.
Seriously though although I do most of my mixing and all my midi on the PC now. My BOSS is, and has been a great servant and even when I upgrade my sound-card in my DAW (Soon hopefully!) it's still going to be my workhorse for doing quick demos. Once you get used to it it is really a quick way to record despite the mixing limitations.
I've had it a quite a few years now, since before home PC recording was really cheap. It cost me nearly £600 and it's been worth every penny. I still record vocal, guitar and bass on it. Then transfer those recordings losslessly into my DAW.
Luckily it's worked perfectly for me. But again anything I record on it automatically gets transferred to the PC so a disk fail is not a problem. I know..."!stable door open...horse gone!"
BUt I hope your replacement drive works 'cause it really is a great piece of kit.
Good luck with the repairs.
