SD card reader not showing up on the computer

by jzou / February 4, 2009 10:09 AM PST

I have recently purchased a Compaq TC4200 tablet. It has a SD slot on the side so I decided to try it out the today. But the card reader doesn't show up on my computer, and device manager showed a SDA Standard Compliant SD Host Controller.

I am using windows XP tablet edition.

Make it their problem.

But if you must, check with TWEAKUI (see google) to see if drive letters are hidden.

It's possible they didn't install the OS proper so while it's new, why not use the restore media and start fresh?

not an option

Did I mention it is a refurbished tablet? So there is not restore cds. I am stilling trying to deal with the company that sold me this tablet, (they owe me $40) they are one of the most incompetent companies I have ever had the mistfortune to come across.

Ouch, ouch.

So no restore media means you are on the edge of having to find them, or pop for a full XP license and CD. Why keep this? I see troubles.

-> Back to DIY stuff.

Now for a limitation issue.

Some card readers don't work with large SD cards. Try one under 1GB.

Also consider forgetting about it. An USB card reader is under 10 at wally land.

It is not that it doesn't work with large SD cards, if that's the case, at least the drive should still show up. it doesn't show up at all. anyway, thanks for your help, I will have to have a very angry phone call with the company tomorrow.

Portafixe from Montreal, Canada sucks! They can't ship, can't count, can't keep track of their inventory, and now they can't even refurb a computer properly!

The drive on some machines DOES NOT SHOW until a compatible, properly formatted SD CARD is in the drive.

Sorry if I didn't tell that.

On your part you didn't tell what SD CARD you put in there.

I see, the SD card is LExar 4GB micro SD with an SD adapter.

4GB is SDHC. Those don't work in many readers.

Try the common under 10 buck USB SD or Micro SD card reader.

Sorry for the typo.
by R. Proffitt Forum moderator / February 5, 2009 9:09 AM PST

I meant "Thank you for supplying the type of SD card." It helped to nail down what to look for.

And if that fixed it, let the forum know.

it did. sort of

It definitely fixed it. except now the drive is being shown as a DVD drive. LOL. But that's ok. I can live with a mislabled drive.

Thank you for your help.

Restart Computer with SD card in
by littlebylittle2 / May 25, 2010 3:36 AM PDT

Have you tried restarting your computer with the card in? That is the only thing that seems to work for me. I could find my card in Device Manager but could not access pictures and music files that I knew were on it until I rebooted my computer. It also takes over a drive that is already assigned on my network. Best of luck!

SD Card - how I fixed mine
by Zuloc / January 8, 2011 12:08 PM PST

I went to the manufactures website for my Computer there was a firmware update for my SD Reader, I installed it. Then I went to my system folder in control Panel went to device manager and uninstalled the SD card Reader and rebooted my computer. When it rebooted, it reinstalled the device drivers for the SD Card reader, I was then able to read my 4GB SD card as the old firmware could only read 2GB SD cards so there was update to firmware to allow it.
