When I connect up my Toshiba USB 3 external hard disk to
my Thinkpad, it detected it initially. I started copying lots of
files (using xcopy) from another USB HDD to it & just a few
minutes into it, the Toshiba USB drive got "disconnected".
I'm sure the USB cable connection is firm.
I would disconnect this Toshiba USB HDD & connect it back
& repeat the same copying again & it consistently (3 times in
a row) give this phenomenon.
I then disconnected this USB HDD & connect up a WD USB 3
HDD to the very same Thinkpad USB port & repeat the same
copying but don't have any issue with this WD USB 3 HDD.
So look like it's not the Thinkpad's USB port nor the Thinkpad
but the Toshiba USB HDD.
I haven't got to try out this Toshiba USB HDD on another PC/
Attachment 1 is the error that surfaced in Event Viewer of this
Thinkpad when the Toshiba USB HDD started to lose connection
& attachment 2 is the error that happened at about the same time.
Any idea & what other troubleshootg steps I can take?
