However, my understanding is that they have a small on-drive battery/capacitor that stores sufficient energy for the cached write(s) to complete in the event the system's power abruptly cuts off. Granted, this is purely hearsay, as it's been a long time since I mucked around with hardware much. -tkc -- https://mail.python.org/mailman/listinfo/python-list
