My 4GB Micro SDHC memory card isn't detected by the computer

I need some help. The problem is this: i have a desktop pc with Windows Vista which has a memory card reader (with SD). Then, I want to copy some documents and other files to a 4GB Micro SDHC memory card which I use with my HTC P3300 but, at some time ago, it passed almost 5minutes so the computer would read the memory card (what I think it's to much because I have a Nokia 2 GB card which takes less than 10seconds to read).

The last week it started not to read the memory card, this is, when I put the 4GB memory card in the memory card reader of my desktop it won't read the memory card!!! Now I can't transfer things to it (because ActiveSync doesn't go on on my PC)!

Is there anyone who can help me? I would appreciate...



Thanks.

How old is your reader?
for instance, my old reader doesn't read HC...

[Rudegar]

most older sdcard readers dont support sdhc
a few have firmware upgrades for the readers but most dont

[nir36]

some readers can't even be upgraded...
you should check your reader.. go to the manufacturer's website and check if it has a firmware upgrade.

I just don't know who is the manufacturer of my memory card reader... I just know it has a SD reader, MS/MS-Pro reader, CF/MD reader and a SM reader... It came with the computer when I bought it and that's the reason why I don't know its manufacter. Can someone help me?

dude.. there are new card readers which read SDHC.. they cost like 10-15$
go for it :)
unless you know manufacturer this is beyond help.
(last thing i can think of is that you go to to control panel/system/device manager and look it up to see if the company's name is stated)

Or you can use somthing like WM5Storage (http://freewareppc.com/communication/wm5torage.shtml) :) as far as I know, you don't need AS running on your PC :)

with a little luck, you can just plug in your ppc to usb an can access your Storagecard via "My Computer/Explorer" :)

both work fine for me (and my TyTN with 4GB SDHC :)

Oh, thanks! I'm just gonna try it... Then I'll reply...

[diogogomes11]

It really works! Thank you very much!

But WM5torage is slower than writing to the card directly (correct me if I'm wrong).

I had (have) the same problem.
My notebooks internal card reader doesn't recognize my 4GB card as well when I run Windows XP.
If I boot Linux it works like a charm...

Looks like a driver issue (at least in my case) but I haven't found a working one yet.

I've allready noticed it... but it doesn't matter... I just have to wait some more time...

that could depend on the usb connection :) my Hermes/TyTN just have USB 1.1 and my Cardreader USB 2.0 .. so the cardreader is much fuster :)
