Out of the blue, yes. I think it's actually userspace (udev/udisks?)
which tries
to read a few block from the very end of the device, which confuses
the drive firmware.
Sometimes it recovers and then it can be mounted read-only without issues.
It's not a kernel fault, the drive is broken.
Still, is there a userspace option (sysfs attribute perhaps) to limit
disk capacity to
a certain block count?
Thank you!
