I have a number of Solaris DVD and CD iso files backed up on a ZFS mirror.

Any attempt to copy or digest one of the DVD files fails with an I/O
error.  I don't appear to have any problems with the CD images.

The system is an AMD 64 (ASUS A8N-E) running build 41 with two SATA
drives connected to the on-board controller.

digest -a md5 sol-nv-b46-x86-dvd.iso
digest: error reading file: I/O error
digest: crypto operation failed for file sol-nv-b46-x86-dvd.iso:
CKR_GENERAL_ERROR

for i in 1 2 3 4 5; do digest -a md5 sol-10-u2-ga-x86-v$i.iso; done

Nothing is logged in messages when the errors occur, but I do see
several messages

opening
/devices//[EMAIL PROTECTED],0/pci1043,[EMAIL PROTECTED]/[EMAIL 
PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED],0:q,raw
failed errno 6

where pci1043,815a is the SATA controller, which leads me to believe
there may be a problem with the hardware.

Ian.
