I'm trying to install apache from the  package, but I got an error code 1:
   mkdir /usr/local/lib/httpd
   sd0(esp0:3:0): medium error, info = 1955972 (decimal), data = 00 00 00
   00 11 01 00 00 00 00
   mkdir: /usr/local/lib/httpd: Input/output error
   *** Error code 1

   Stop.

This is on a Sun 4/40 (sun4c), NetBSD 1.4.2/sparc.  What's different from
what I've done before is that LOCALBASE is set to /usr/local, which is
mounted on a different partition (sd0f) from what /usr, including pkgsrc,
is mounted on (sd0d).

Should /usr/pkgsrc and LOCALBASE be mounted on the same partition, or is
there something wrong with the disk?  The disk is a rather lightly used
Quantum Fireball TM1280; there's never been an indication that it was
bad before.  Does NetBSD have standard tools for scanning a disk to look
for errors, and then mark any bad sectors?

What's the recommended way to proceed in such cases?  TIA
