Hi!
I purchased a Kingston DT100G3/32GB and it corrupts large files (> ~500MB) on
write with plain "cp". I already filed a bug at
https://bugzilla.redhat.com/show_bug.cgi?id=1371183
with detailed descriptions how I tested the device.
Kingston suspected a broken device and sent me a new one as replacement which
doesn't work as well.
I figured out now that it works with
quirks=0951:1666:m
I tried options "r" and "g" as well which didn't change anything.
So I prepared a patch for unusual_devs.h (against 4.7.3 source tarball)
