Comment 11 for bug 61235

Unfortunately, GO_SLOW does not fix it. It needs max_sectors to be set to 128. This should either be done in the kernel or userspace. I understand that one class of USB mass storage controllers (the genesis series?) get max_sectors=64 set automagically.

This device needs the same workaround (though it'll take 128, faster than 64). Whether it's more "correct" to do it from udev or the kernel, that's not for me to decide.

P.S. I started trying to write a udev rule for this, but am failing miserably. Can anyone point me to the right direction for setting max_sectors from udev?
