There may be good reason why RH doesn't support xfs, but if your
kernel already can handle xfs, would a rebuilt kernel help? As a test,
still with a SL5 32-bit system, I installed xfsprogs, then took an
unneeded partition (/dev/sda11 with the obsolete SL3.0.9) and did
mkfs.xfs -f -L test /dev/sda11
The result was an xfs partition that I could mount, write to, and read
from. I don't know what would happen if you tried mounting and reading
your USB 3.0 disk. But even if it can't be read with the standard kernel
I don't think harm would be done to the disk, especially if it's mounted
readonly ("-o ro").
