Comment 109 for bug 792085

For USB 3.0 Disks, Across Ubuntu Distros..... This surely needs to have more priority.

Unless this is fixed, We noobs might simply give up on Ubuntu/Linux altogether.

My Machine: Ubuntu 14.04 LTS, NVidia Chipset, Asus X552C

Device: Seagate BackupPlus 1 TB USB POwered Ext Hard disk Issue: Ext HDD keeps spinning(I place the palm below Ext HDD & feel the spinning is still On), Light keeps glowing, Nautilus Left Side Panel shows the disk is till mounted.

mount will list all mounted disks.. I used & found Seagate HDD is mounted as /dev/sdb1 I installed udisks using apt-get & ran these 2 commands in terminal. udisks --unmount /dev/sdb1 udisks --detach /dev/sdb

Caution***not udisks --detach /dev/sdb1, It is /dev/sdb

Now, the Nautilus Left Side Panel doesn't show the mounted icon for the Ext HDD, but the spinning is still on.

I tried sudo umount -f /dev/sdb1

I get the error, umount2: Invalid argument umount: /dev/sdb1: not mounted

My Problem is I've already lost 2 different 1 TB HDD's while working on Ubuntu. Data Retrieval costs are upwards of $3.5 per GB in Bangalore (200 INR per GB at SP Road....)

Does anyone have a solution..... Note: I've had the Ext HDD attached to the laptop from past 7 days & spinning is still On.

I'm at end of my wits & can't afford to loose the data in this HDD.
