Abstract
Recent research has shown that even modern hard disks
have complex failure modes that do not conform to ``fail­
stop'' operation. Disks exhibit partial failures like block
access errors and block corruption. Commodity operating
systems are required to deal with such failures as commod­
ity hard disks are known to be failure­prone. An important
operating system component that is exposed to disk failures
is the virtual memory system. In this paper, we examine the
failure handling policies of different virtual memory systems
for different classes of partial disk errors. We use type and
context aware fault injection to explore as many of the inter­
nal code paths as possible. From experiments, we find that
