I didn't notice this one,

 kernel:[121311.947209] journal commit I/O error
that's some more serious problem.
You should have more info saved in the syslog file.

While I don't know about the black magic of Y-cables, I'd take a look at
the smart data of the drive, esp. Current_Pending_Sector and
Reallocated_Sector_Ct . If it has more than a few bad sectors I'd try to
RMA the drive.
You may need additional switches for smartctl to get it to work over
http://sourceforge.net/apps/trac/smartmontools/wiki/Supported_USB-Devices (and
it may not work at all, unfortuanately, though there are some Toshibas
in the list)
