I have a Raspberry Pi B+ and a external 2.5" Seagate Backup Plus connected via USB (no external power source). Since the latest update, my Pi can no longer automount the drives that are plugged in USB ports. When I manually mount the HDD, it doing well in idle mode but when I began to read and write data to it (run a torrent client) the drive keeps power up and down (ie the LED is flashing about 1 time per second and I can feel the HDD spinning up and stop). I also tried to mount the HDD on boot using ftab but it useless.
Can anybody help me with this problem?
