`lsusb -t' shows the maximum speed the USB device may operate at.

But this one has bad blocks that can't be read. If the NAS does just mirror all sectors from this to the second drive then it will have read errors. Is there any data on this disk that you hope to save? If not, write to all its sectors so the drive's firmware can abandon attempts to read the dodgy sectors and start from scratch by then partitioning it and making filesystems. -- Cheers, Ralph. -- Next meeting: BEC, Bournemouth, Tuesday, 2019-07-02 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk/ New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
