Our nightly backups outgrew the 500GB disks I was using so I've bought some 1TB disks, and they aren't working properly. Both the old and new disk are USB3 disks on a USB3 controller which seems to require a reboot every 50 plug/unplug cycles or so but otherwise previously worked well.
The symptoms are: ... . cable bad (it's well less than 3M) ...
My household has ongoing issues with USB cables, particularly the micro ones, and it is usually power rather than signal - the specs for wire size seem to be honoured in the breech, and USB3 micro seems to elevate the problem with its dinky little contacts and less than positive mechanical locking.
Seconded. I have had a nightmare month or two of failing USB cables, and new cables which can't actually push full power through themselves. I suspect this is partly because I went around upgrading my USB power sources from 500-1000 mA to 1000-2000 mA units, which is well above the original USB spec.. but yet now quite common for charging phones and driving embedded boards. I'm currently having some success with 30cm micro-usb cables from Korea that seem to work fine. I also have some $10 cables from Jaycar which are annoyingly long (1.8m) but which otherwise seem to be built well enough to carry power.
