Hi, I've done some searching but haven't found a successful solution. Here's the issue:

Recently, my 2010 MBP stopped mounting firewire drives (they don't show in system profiler, either), however if they are plugged in at start up then they mount but only at 400mbit/s.

I have tried resetting the SMC, PMU and removing the battery for an hour to no avail.

I was running Snow Leopard and have upgraded to Mountain Lion. Issue started before the upgrade.

Any advice would be greatly appreciated as I do a lot of transfers over FW.

Cheers,

Daniel
