Do you have any idea how non-portable that is? It depends too much on both
the hardware platform and the OS version.

At the risk of driving the dagger deeper into SGI's heart, it works fine on
both the RS/6000 and a Sun running 3.5... Perhaps you should consider fixing
the driver in the next release?

As pointed out to me by several people, The easy fix is to remember where I
am while reading. When I get a read error, seek back to that position and
read the rest of the disk using smaller blocks.

While this works, it is a hideous kludge.
