Please confirm my assumptions as follows:
- You have one slot for a memory card in one card reader.
- This one card reader plugs directly into the USB port on the computer.
- You have two SD flash memory cards that you insert, in turn in the one
slot.
The plug/unplug statements, in my normal use, would apply to the USB
connection. I think you are applying them to insert/remove of the card
into/from the reader. I am assuming that you are not plugging and
unplugging in the USB connection but are inserting and removing the flash
memory cards.
This being the case, the multiple LU issue is not your problem.
Suppose you do a clean boot, and then you reverse the sequence using
"flash drive" B first. Does the flash card A then fail to mount but the B
mounts the second time? In other words, does the same card always fail to
mount or does in not matter?
Is the 128MB MicroAdvantage as secure digital card or MMC? An SD card has
the write protect switch on the sice, An MMC card does not.
I am sorry for all the questions. I just want to make sure I give the
best advice I can.
