What does Lawrence D’Oliveiro mean by >"before >showing signs of failure."? With a conventional hard drive, first you might see some error numbers creeping up on your SMART tool, as individual blocks start failing. There is a bad block replacement process that is transparent to the OS so all you see are bad numbers on SMART. Then you start getting media errors and then it's all over. >This quotation gave me the impression that Lawrence D’Oliveiro does >not expect the dramatic all-or-nothing scenario that Don Y reported. You can also have dramatic all-at-once errors when the interface fails. I have seen many USB SSDs where the SSD memory remained fine but the USB interface could not get to it. I have seen lots of ways that SSDs fail. There are likely lots more than I haven't seen yet. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."
