Card Reader - puzzle / enigma - please help.

Steven Toney

Hi XP os experts, I have a problem to solve.

let me set the stage

I have 4 computers of various types all with card readers - 2 of the 4
operate normally -- which means the USB card reader are visible in both disk
management and in explorer with assigned DISK number like disk 2...disk4 etc
and in both disk management and in explorer they are assigned drive letters
by XP -- lets say drive letter E,F,G,H -- the OS sees the card reader and
its available slots even with inserting a CF, SM, SD etc in explorer and
diskmanagement these are listed as removable. Inserting a card in the slot
in the reader then will cause the system to beep and the card is visible and
accessible

I also should say this is with the machines internal card reader, but I
tested the same action with an external SANDISK 11-1 model - exact same
behavior

ok to the problem - 2 of the 4 machines no longer work correctly with any
card reader - I need to say these 2 machine are identically configured
shuttle SB61G2s and I use acronis image to clone between them as sparing
configuration

Here's what happens the card read is clearly recognized by the OS in
diskmanagement and the device manager - the drives show as they do in the
other working machines in as removable drives name disk2...disk4 etc - the
difference is not a drive letter is not assigned - the letter is not
assigned regardless of have a card in a slot or not -- I can insert and
remove cards, but I execute a rescan in disk management to see the card
partition and size on the right view of each disk of disk management -- it
see the partitions and size fine in disk manager, but will not assign a
drive letter --

the machine will not beep on insert of a card and they slots as drive never
appear in windows explorer despite showing in disk management - even if I
manually assign a drive letter in disk management - the slots/drives will
not appear in windows explorer

the card readers use to work on these machines

it's clear this is an XP software configuration change - likely registry
issue, but how do I fix it short of a total reinstall and reload of all my
programs -- I can do that, but it is easily a 3-4 week exercise to get
things back to normal operations

thanks

There are some reports that a more or less failed installation
of the Daemon Tools V4 can cause this behaviour.

It's suggested then to deinstall the tools and to remove
some files from \Windows\System32\drivers

sptd.sys
secdrv.sys
sptd.sys
sptd7021.sys
sptd3677.sys
