I've been having a weird problem with my Sound Devices 702. It's less than a month old. Basically, the Compact Flash card I use (Kingston CF 8GB 133X) mounts very inconsistently. When I first got the 702, I never had any problems. Plugged it in, and it appeared in my finder. Now, I have to try at least 10 times before the card mounts.
I'm running the 702 via the Firewire 400 through a 400 to 800 cable into my Mac Pro's Firewire 800 connection. At first I thought that it might be a Lion issue and reinstalled to no avail. I've tried all four FW 800 ports on the Mac Pro with no success. I've made sure that other Firewire devices mount, and they do with no problem.
Could this be a problem with my 702? The device recognizes the connection and goes into the proper mode, as indicated by the 702's screen. But it doesn't mount. It does show up in Disk Utility, but I can't run any operations. Basically, the 702 gets stuck in the Firewire connection mode, and I have to physically disconnect the power to try again.
I ordered a CF card reader, which will hopefully help. But I'd still like to see if anyone has any ideas in the meantime, as I can't access any of my recordings. Perhaps at this point I should contact Sound Devices support?
