Peter,

Limiting reads to a single track will have little impact on the current
filesystems, since they only read a cluster at a time anyway (~4K). But
my new filesystem is purposely set up so that contiguous reads of ~64K
will be common to the disk. Could we perhaps allow large reads until some
specific error is detected, and *then* drop back to single-track reads?
