Unfortunately, these Toshiba 128GB USB sticks didn't work.
30 November 2018
These USB sticks must have been faulty. After doing a "Quick Format" to NTFS, I tested one with a few MP4 files, and they seemed OK, and then filled it to the brim with loads more MP4 files. Unfortunately, virtually all of the files refused to play on my TV, which showed a broken file icon on screen. Strangely, some MP4 files were OK, including the originals I had tested on a short-run. Copying these faulty files back onto the hard drive of my computer from the USB stick revealed that they must have been corrupted by the stick, as they also could not then be played on the computer (though the originals could).
Trying a second stick, I also formatted it to NTFS, using "Quick Format", but a message appeared, saying the formatting couldn't be completed! I therefore felt a Full Format would be necessary, but when this was started, the speed on the progress bar indicted the formatting would take about a year! - so I stopped it, and tried a Quick Format again, which, on this occasion, was completed. I then spent a very long time copying MP4 files onto the stick, which, according to my computer screen, showed was actually happening. However, when eventually putting the stick into my TV, it refused to recognise the drive, even after several attempts. To my astonishment (and horror), when I plugged the stick back into my computer, it was totally bereft of files, and when I checked its Properties, the computer told me it contained an unrecognisable file system!
These two sticks, plus a third one I didn't want to waste time on, were all returned pronto. At the time of writing, I await a refund and notification that the three sticks have been received by Amazon, but I'm confident these things will happen.
This is a real shame, as I have used two Toshiba USB sticks before, though 64GB ones, half the size of these faulty ones, and they have been superb. I've ended up instead buying just one "SanDisk Ultra Flair 128GB USB 3.0" stick to test, and, after filling it to the brim, have found it works perfectly, both on the computer and on the telly. It is also, of course, much faster, and was a few quid cheaper than the Toshiba ones.
