All dead after just one testing.
Became write protected, permantely.
Bought from Shopping Square 1 for 3 deal.
Facts:
The 32GB USB drive doesn't have serial number printed on the case, there's an obvious place for the serail number to be printed I think.
ShoppingSquare usually will send you an tax invoice via email for your order. But for those 9 32GB units ( in 3 orders), they didn't provide any tax invoice.(Purchased on 5th Dec).
H2testw will pass write and verify, won't kill the drive.Average write speed 12MB/s for writing 29GB, Typical USB 2 speed.
TxBench will make the drive became write protected right after the benchmark.
CrystalDiskMark7 will make the drive became write protected right after the benchmark.
It happens on different computer/laptop so it's not my computer's problem.
Diskpart regedit etc can not recover it.
It seems to happen often, my friend bought the same model in other country and having the same problem(after some daily use not benchmark testing).
Sandisk switched to use their own flash chip controller, thus the chip controller and the chip can not be identified in most tools.
And there's no factory tool available to reprovision the usb drive.
I guess this is for cutting cost as well as fighting with fake usb drives.
