I've bought a new hard disk, a Seagate (Backup Plus), but I'm having problems with it.

Firstly, it doesn't mounts every time I plug it in. In such cases, I've got to restart the machine to work with it.

Secondly, whenever removing it, the rsyslogd and kworker commands go berserk , hogging the CPU and the rsyslogd command writes this to the /var/log/syslog file:

cmd urb submission failed

My observations: for the first problem of mounting ,I tried to mount it manually but this was the result of dmesg:

One more observation is that it works fine when I start the laptop with the drive already attached. It neither has the auto mount problem , nor the CPU hogging problem.

What distro are you on ? What kernel version ? Have you tried other USB ports ? –  don_crissti Mar 26 '13 at 20:40
    
It's mint 14 nadia kernel version is: 3.5.0.17 it's same for other ports also. –  deathholes Mar 27 '13 at 4:23
    
Add the line blacklist uas to /etc/modprobe.d/blacklist.conf see if that changes anything. –  don_crissti Mar 27 '13 at 12:17
    
didn't help. @don_crissti –  deathholes Mar 27 '13 at 13:16
    
@deathholes did you ever resolve this issue? I am seeing it with the same Seagate disk on a QNAP NAS :( –  quaylar Apr 4 at 19:00
