Tal Nevo (talnevo-i) wrote on 2012-11-23: Writing on a certain USB HDD causes corruption

I bought an external USB enclosure for a SATA 2.5" hard drive. When using this USB drive with Microsoft Windows, it works perfectly - I have no problems reading and writing from/to the drive.
However when using this USB drive in Ubuntu (10.04 as well as 12.04) I can read the data on the drive without a problem, however after I wrote to the drive I started getting corruption errors.

To simplify the detection of the problem I used a new empty hard drive with this USB enclosure.
I wrote zeroes on about 1GB of the start of the drive (using a different USB to SATA interface).
When I read from the drive using the commands

dd if=/dev/sdb of=/tmp/xxx bs=1M count=100
hexdump -C xxx

The output of hexdump indicates that all that was read were zeroes:

00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
*
06400000

However, after I run the following command (writes to drive):

dd if=/dev/zero of=/dev/sdb bs=1M count=100

and then these commands:

dd if=/dev/sdb of=/tmp/xxx bs=1M count=100
hexdump -C xxx | less

I get the following output:

This indicates that although I tried to write zeroes to the drive, what was actually written was mostly zeroes, but also these strange blocks starting with "USBC". According to the dump these show up at the beginning of every block (block size was 1M bytes) that the 'dd' program wrote.

The output of lsusb on this system is:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 002: ID 14cd:6116 Super Top M6116 SATA Bridge

The last entry being the USB to SATA controller that I think Ubuntu has a problem with.

Thanks,
