From 69bdd88ca2670c321fef774e77059516f836c6f2 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Fri, 1 Sep 2006 15:50:23 +0200 Subject: [SCSI] Wrong size information for devices with disabled read access When accessing a device with disabled read access the capacity is set randomly to 1GB. This makes it impossible to userspace tools to detect invalid device capacities.
