Default little memory card slot

I have a slot for a little memory card (I can't remember what they are
called) in my laptop. a Dell Latittude E4300, running win7, and the
computer doesn't seem to know it's there.

Is there some way I disabled it?

I have one in the Acer Aspire running XP, and that always knew it was
there.

SD is the norm for laptops etc. Micro SD is what go into phones.
You can get an adapter to allow you to put the tiny micro SD card into a
larger SD adapter and then into your Laptop.

Look in device manager and see if there are any ! next to the device (or
any device like unknown). You might be missing drivers.

Have you verified the memory card is good? Have you tried another card
or put the same in another machine?

https://www.diffen.com/difference/MicroSD_vs_SD_Card
and from the pics here, it's even written on the card "micro".

And I'm not interested in the article but the first picture shows the
two side by side very well.

( DMESG dump from http://natisbad.org/E4300/index.html )

SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter

https://www.e-devices.ricoh.co.jp/en...cif/pcc/5c821/

"It seems that my Ricoh R5C822 SD card reader supports SDHC (class 4) as well!"

SDSC (SD): 1 MB to 2 GB, some 4 GB were made
SDHC: 2 GB to 32 GB
SDXC: 32 GB to 2 TB

That suggests 32GB might be the largest SD you could plug in.

The Ricoh site didn't leave a datasheet for me to look at,
only the package outline document ("chip scale package" or CSP).

The bug trail here in Linux for the thing, probably is a matter
of not waiting long enough on a write. A delay_write failure
on Windows might be on the order of 5 seconds or longer. You
can get delay_write failures on older Windows, if the OS runs
out of some flavor of "pool".

https://bugs.launchpad.net/ubuntu/+s...ux/+bug/247819

Anyway, keep looking for a datasheet for the R5C822 to see
whether the SD really is an SDHC controller. I think the
best I have in the house here is SDHC, don't have an SDXC yet.
And the one SDHC I bought, is a 32GB one.

It's too bad the slot just didn't say underneath "32GB"
so we'd know.

Agreed. Sometimes called SDHC, but that refers to the capacity not the
shape. About the shape and size of a standard UK postage stamp, with one
corner cut off.

You can get an adapter to allow you to put the tiny micro SD card into
a larger SD adapter and then into your Laptop.


Poundshops often sell SD card readers (look like memory sticks with a
slot) that come with such adapters; might be cheaper than just the
adapter on its own! Or, they often (sometimes it seems like "most") come
with a micro-SD card.

Look in device manager and see if there are any ! next to the device
(or any device like unknown). You might be missing drivers.


Certainly, if the machine wasn't bought new, and there's any reason to
suspect that Windows has been reinstalled at any time, it's quite
possible for the relevant driver not to have been installed. I think
under some circumstances, hardware for which no driver has been
installed may not show up _at all_ - rather than just with a ! - in
Device Manager.

It's also possible (I think it's a setting in Windows, but may be
hardware-specific) for the reader not to show up when there's no
(working) card in it.

Have you verified the memory card is good? Have you tried another
card or put the same in another machine?

Good questions.
