"Transport endpoint is not connected" after working for a while.

[arist...@gmail.com]

I'm having problems using my WD 2.5 1TB USB3.0 HDD (WDBBEP0010BSL)

I'm using it on a Cubieboard with Debian Wheezy armhf

Here are the details.

It works fine for a while and then disconnects.

Any help much appreciated.

 

$ mount -t exfat /dev/sda2 ~/extfat
FUSE exfat 1.0.1

A test speed shoes the expected speed around 27MB/s:

After disconnecting, hard drive changes name:

$ sudo mount -t exfat /dev/sdb2 exfat/

After mounting again, the speed is very low.

From this point it the speed seems to throttle at 1MBps. Using wget it seems to stay for about 5 seconds at 9 MBps which is the maximum the network interface supports and then drops bellow 1MBps.

Hi,

"Transport endpoint is not connected" error means that fuse-exfat either
crashed or called abort(). Please show /var/log/messages.

There are I/O errors in the log. So, it's a hardware issue.

An hardware issue? Like what? From the host or from the disk?

The disk seems to work fine with other OS

Well, if the disk is OK, then it's Cubieboard. Messages like
lost page write due to I/O error on sdb2
from kernel block layer indicate that things went wrong at hardware level.
