The Kernel driver of cypress corrupts file-system and partition table of external hard drives with M6116 SATA Bridge

I reported the issue in Fedora as well as in Gentoo Bugzilla. For those who suffer from this issue, I have the quick solution before this fix will be made available with the next kernel releases to come.

The corrupt behavior is caused by a more resent version of bcdDevice 2.20.

Code:

lsusb -vd 14cd:6116
  idVendor           0x14cd Super Top
  idProduct          0x6116 M6116 SATA Bridge
  bcdDevice          2.20


In the Kernel Source drivers/usb/storage/unusual_cypress.h alter following line

Code:

-UNUSUAL_DEV( 0x14cd, 0x6116, 0x0000, 0x9999,
+UNUSUAL_DEV( 0x14cd, 0x6116, 0x0000, 0x0219,
        "Super Top",
        "USB 2.0  SATA BRIDGE",
        USB_SC_CYP_ATACB, USB_PR_DEVICE, NULL, 0),


For the newbies to Gentoo Linux.
Do a make clean before compiling the new kernel!

That fixed my issue on Gentoo Kernel 3.6.11.
