No interpereters for files on a specific parbreastion

When I run scripts that require a shebang to run, where the scripts are on a specific parbreastion, 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 ofbin-sh)

First, my system specs: * Duron 750MHz, 768MB RAM * Debian sarge, last updated with packages from jigdo CDs made in early December. * is mounted fromdev-hda1 *home is mounted fromdev-hdb1 *home-shortcircuit-data-external is mounted fromdev-sda2 *home-shortcircuit-data-fat32 is mounted fromdev-sda1 * andhome 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 parbreastion *dev-sda2 is a 170GB ext3 parbreastion * I have approx. 11GB free ondev-hda1, 21GB free ondev-hdb1, and significantly more free ondev-sda2.

When I run interpereted scripts from any folder underhome-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 needingbin-sh,bin-bash, andusr-bin-perl.

When I copy any of the scripts tohome-shortcircuit-data,home-shortcircuit, or evenusr-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 -vdev-sda2" doesn't show anything unusual. "fsck.ext3 -cc -fdev-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.)
