Passport 2TB USB3, on Mac OS 10.8 MBP, bought just 3 mons ago been working fine. Formatted as NTFS, just readable on Mac.
Started to eject by itself - sometimes it still shows as mounted but can’t browse or see folders / files. It seems likes its fine until I start doing some heavyish data transfer from (or to) the drive. Files all look like they’re there but haven’t verified.
What can I do to test where the fault lies and get a fix?
