Re-Plugging usb or unbinding/binding via /sys/bus/usb/drivers/usb/unbind wouldn't change this. 2) Only (!) after power-cycling the external USB-Drive is it correctly detected with sector size of 4096 bytes. When detected wrongly mounting fails as (probably) start of partition is calculated wrong. It seems to mount, if using a loop-device with correct offset. I found similiar indications at http://www.computerbase.de/forum/showthread.php?t=1283844, so it might be a Toshiba Canvio issue. While sg_readcap reports logical block length of 512 in case 1), it reports 4096 in case 2). Hdparm however seems always to report logical sector size = 512, physical sector size = 4096. Reproducible: Always Steps to Reproduce: 1. reboot 2. drive shows, fdisk shows partition 3. mount partition Actual Results: mount fails (NTFS signature is missing ...) Expected Results: mount works / fdisk ought to report sector size 4096. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
