[daip] Y2KL test

[Alice Argon]

Hello,

We are running Y2KL tests on a MacBookPro computer with two disks.  Disk 1 is 
an internal ATA drive and disk 2 is an external fireware disk.  We ran three 
tests; the first succeeded and the others failed.  The details of the runs 
and error messages are outlined below.  It appears that files can be written 
to disk 2, but renaming (within AIPS) fails.  Perhaps you could shed some 
light on why this is so.

Thanks,
  Alice Argon


Test 1:
ddisk 1; mdisk 1; tdisk 1....................................................OK


Test 2:
ddisk 1; mdisk 1; tdisk 2.................................................Fails
