I never had a PCMCIA before, but from my experience with my USB drive, I
need to umount it before I unplug it from the computer otherwise when
time I mount it again, I need to increment the number by 1.

e.g, mount /dev/sda1 /mnt/usb

unplug

to mount it again, I need to

mount /dev/sda2 /mnt/usb

but if I umount before I unplug, I don't have to change the mount
device.

how about "fdisk -l" see what it says?
