I was having experiencing the same symptoms on my machine, first on Lucid and later on Maverick. Random disconnects of an external 2TB USB HDD in intervals ranging between mere minutes up to 2 hours. Even weirder, when I manually unmounted the (single) partition but left the drive running and connected, the partition would remount after a couple of minutes.
Disconnects would happen randomly, even when not accessing the drive. I upgraded to Maverick to see if that would resolve it, no luck. I tried the power level trick, no luck. I tried the drive on other machines (and OSses) and not once experienced these symptoms. I do have one other external USB HDD in a 2.5" enclosure (bus powered) which does not exhibit this problem on the same machine. On a hunch I removed the only PCI-card I have in this machine - an Adaptec SCSI controller which I only use for an old film scanner. I have not experienced anymore disconnects since. Driver issue? IRQ issue? I'm not knowledgeable enough to comment. If I can help by providing logs etc. please let me know. The card is not installed anymore at the moment but can put it back in in order to provide useful information.
