No interpereters for files on a specific partition?

    When I run scripts that require a shebang to run, where the scripts are
    on a specific partition, bash says something analogous to:

    -bash: ./error.sh: /home/shortcircuit/sh: bad interpreter: Permission
    denied

    (contrived example using a friends system; I don't have access to my
    machine from work/school. /home/shortcircuit/sh is a "chmod -x"'d copy
    of /bin/sh)

    First, my system specs:
    * Duron 750MHz, 768MB RAM
    * Debian sarge, last updated with packages from jigdo CDs made in early
    December.
    * / is mounted from /dev/hda1
    * /home is mounted from /dev/hdb1
    * /home/shortcircuit/data/external is mounted from /dev/sda2
    * /home/shortcircuit/data/fat32 is mounted from /dev/sda1
    * / and /home are ext3 filesystems. They work fine.
    * /dev/hda is an internal IDE/ATA 20GB drive
    * /dev/hdb is an internal IDE/ATA 40GB drive
    * /dev/sda is an external 250GB drive connected to a PCI USB2 (EHCI)
    add-on card
    * /dev/sda1 is an 80GB FAT32 partition
    * /dev/sda2 is a 170GB ext3 partition
    * I have approx. 11GB free on /dev/hda1, 21GB free on /dev/hdb1, and
    significantly more free on /dev/sda2.

    When I run interpereted scripts from any folder under
    /home/shortcircuit/data/external, I get an error similar to the error
    given above (albeit with a proper path to the interpereter.). I've
    confirmed this for scripts needing /bin/sh, /bin/bash, and
    /usr/bin/perl.

    When I copy any of the scripts to /home/shortcircuit/data,
    /home/shortcircuit, or even /usr/src, they work fine.

    running "mount" doesn't show any flags I don't recognize, nor does
    running lsattr on the scripts relevant.

    "fsck.ext3 -f -v /dev/sda2" doesn't show anything unusual. "fsck.ext3
    -cc -f /dev/sda2" was still running as I left for work this morning,
    but hadn't yet shown any errors after running for four and a half
    hours.

    Finally, dmesg didn't turn up any errors.

    Am I missing something? Are there any other tests I can run? (Be
    warned I won't get a chance to respond with results until Wednesday;
    I'm not going to see that machine until tomorrow night.)
