My test system has a WD MB Studio II connected via Firewire 800 and occasionally also has a Seagate FreeAgent (portable) which I connect via FW 800. IIRC both had multiple partitions and on each one of those partiions was a Time Machine partition.
About a half dozen times during Mavericks testing and development my Seagate FA would “spontaneously reformat” and would be named “MyBook”. Literally there was NO indication this was going to happen, just one day Time Machine would report it was no longer able to find it’s drive and I’d notice the 2 paritions on the Seagate FA had been replaced by a single “MyBook” parition.
After a few weeks I removed WD Drive Manager from the test system and didn’t have any further problems. I don’t test software for WD or SG and didn’t think much about it. I figured WD would have it resolved well before Maverciks actually got released to the public.
