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) ------------------------ $ diff -up unusual_devs.h.orig unusual_devs.h --- unusual_devs.h.orig 2016-09-07 08:35:12.000000000 +0200 +++ unusual_devs.h 2016-09-07 17:04:15.834506827 +0200 @@ -1289,6 +1289,17 @@ UNUSUAL_DEV( 0x090c, 0x6000, 0x0100, 0x US_FL_INITIAL_READ10 ), /* + * Reported by Wolfgang Breyha <wbreyha@xxxxxxx> + * This USB Stick needs US_FL_MAX_SECTORS_64.
