I got almost 3 years out of a (PNY) USB 3.0 stick in the E02 Pogoplug before it went haywire a month ago. It formats and still works, but it's replaced by a SanDisk.
I'd try a direct copy of your working stick over to the 128 GB stick, then resize it internally, but that does seem odd at first.
* PNY 2.0 sticks have been terrible in my experience all around, but their 3.0 have been up there with San Disk.
