Thanks in advance

Hi tubzy,
I'm new to this topic, but I think you'll need a SDHC compatible card reader.
In the linked thread is a solution I think.

EDA-One

no solution still
hi eda-one
sorry this still is no soluton - i do hae the latest sandisk with the card reader and once all this gear is connected to the pc it says...please insert a disk in drive f??
even though the disk is in the usb card reader

did you try format it?

If you have used the card on an 'oldish' PC without the latest BIOS or Windows updates installed it may not be SDHC compatible even using a card reader.
You can also get a situation where formatting using the standard Windows formatter or even just writing files to it from your PC will corrupt its filing system.
There are various utilities available on SD manfacturers sites for formatting and recovery.
Check out the 'Formatting and Read/Write check util in the OEM section here and download the latest drivers for your reader whilst there.

Hope this helps.

Hi and thank you
HI
Even after trying this it still doe s not work,
I have downloaded the utility and attempted to run it but it says no usb found even though it can vonnect to a usb pen drive?? any ideas ??
thank you

I had that same problem when I first got my 4 Gb SDHC card and it was because I didn't connect the card reader directly to a USB port, instead I was using an external USB port. When I put it in to an onboard one, even though all of mine are on the back of my computer, it started working.

8gb card
Hi and thanks for your response.
i am sorry but can you please clarify what you mean to be onboard usb port. Is this the sockets where you normally connect any usb device eg a mouse to a computer or do you mean i have to take the computer apart and do it a motherboard level?
I am not very technical and apologise in advance if it sounds a silly question.
I bought the damn thing and was hoping it would and should work from out of the cardboard package. I can see this on the my computer as an external drive but when clcikcing on it it says insert disk
if the disk was faulty it would not work on the phone but on the phone it says 7.5 gb available and have stored some data there. So i think it it is a case of the pc not being able to read the card and from there i dont know what the problem is.
Any further light on this subject would really be appreciated

You have it right about what I meant. I did mean the sockets where you connect any USB device. You don't need to take your computer apart or anything. If that's what you are already doing then it's possible that the reader that you got with the card may just be faulty.

Not knowing what adapter you are using is a problem. I had similar problems with my first SDHC card and finally went to a local office supply store (Staples) and bought a "Sandisk MobileMate+ USB Memory Card Reader" for $15. It is a memory stick sized device and it accepts the SDHC MicroSD cards directly in it's slot. This works great on any PC so far.
It just may be the reader.

thanks!
This is a nightmare on elm street scenario.
I have finally tracked it to a faulty card reader, so i purchased another one. This one works and we have another problem - cannot copy data file path is too deep???????????
I am openeing another thread for that
Thanks to every1 for trying various solutions

I'm guessing you got a bad card..which is going to happen a lot with these high-cap cards, at least for a while. I am assuming you are using the small, plastic USB reader that came with the 8 gb card....that plugs directly into a USB socket? If not...I can tell you right now..the "older" adapters will NOT work with 4/6/8 gb cards. By this, i mean the adapter/reader that usually comes with the cards in the package. Also, it may sound silly..but make SURE you didnt, or are not, forcing the card into the phone/reader backwards...i know it's silly, but it's damn easy to do..and it usually trashes the card. My 8 gb just got in tonight...and it's working like a champ. I'm guessing you got a bad card. best of luck.

This is crazy. My phone reads the card just fine, but the card readers I have do not work period. 8G SDHC

Diamond CAN READ external SD cards!

According to HTC service manual http://forum.xda-developers.com/showthread.php?t=410653 (picture attached) there are somewere an Y cable and SD card reader !!!!

Till now we just proved the existence of a working SD card reader-cable connected.
Special reader? Special Cable? According with HTC service manual no special software is needed, so the solution is in the HW

MAKE A SMALL Diamond like microsd card reader?
people get some entrepreneurial spirit 3 million diamonds are going to be sold
know some manufacturer which can make it for $10 a piece and you sell it for $49, YOU SELL 250K, YOU MADE over $10 MILLION, theres a life.
or VIEW THIS! http://www.tca-inc.net/usbmatousbbf.html and http://www.bizrate.com/memorycards/oid796436093.html
will that work?

Another USB reader
Check this out.

Nice prices, altough shipping will be put on the price.

I almost hate to ask, but has anyone actually tried plugging in a card reader or USB drive?

If someone managed to cram the features of the smart cable into the space made by the extended battery back cover, we'll have a neat little extension to the phone

Bringing up an old topic.... But just for the info here it is:
I worked with it many times. It can read the SD card but only in special conditions. You cannot use it as a USB host and read-write files etc.
The cable is a special cable so don't bother look for a ready made one commercially.
Regards!

i think its purpose is for service only

I think the SD Card reader in the picture is simply a USB OTG Bridge that can transfer data to USB client devices.
Here is a similar product:
http://www.everythingusb.com/sima_hitch_usb-101.html

Forget hitch, the reader is a plain card reader.
And yes it is used for servicing only.
I could go into further details later if you want or even show how to build one.

Is there something useful here?

Hm... Have no idea, didn't tested it.

if that's a plain card reader, it means the Diamond is an USB host or OTG device, right?
if that's true, we could provide an external 5v power to the card reader, and connect card reader's D+ and D- pins to Diamond to get it work, right? ... is it required to connect the both sides' Vcc and Gnd pins? Or, maybe the external power is not required?
thanks,

It will only work for servicing purposes. Nothing else. About the connections you are right.

I see. So it's useless for the rest of us.
Thanks,

Mobidapter: MicroSD to USB adapter

This adapter can be used as an alternative for the USB-Host functionality but I was afraid the microSD part wouldn't be long enough to fit the HD2 MicroSD slot.
So I managed to get its microSD part length according to expansys' product image:
The length is only 17mm but the minimum length to get it work with HD2 must be 20.5mm. I used a calliper to measure that.
So, I was hopping anyone would come up with an idea to use this adapter with HTC HD2.
Please notice that the adapter price is £29 excluding the shipping cost so I prefer not take the risk to disassemble it for extending the microSD length if it isn't possible.
Thanks in advance,

that's a very interesting product..

What is it for, are you trying to use a USB stick instead of your micro SD card?
If so, why?

a portable HDD caddy LOL
shame though, the MicroSD port wont put out 5v 500mah
although its probably enough to power a CF/MSproDUO/XD type of reader for example to clear some space on your digital camera card without deleting images (or simply to view them on a bigger screen )

Sometimes you really need work on a USB stick but you don't have access to PC.
Or as quasi_mojo said you can connect a card reader to your device...

Will I be able to play some mp3's directly from a pendrive with this device? Because I have about 25GB of music and I can't afford a 32GB microSD card.

i THINK (i could be wrong...) a pendrive would require more nearer 5volts to work...
opened up my SDcard reader a few days ago, plugged into usb with a 2gb sdcard...it was pulling 3.4-3.6volts while accessing the card, which is damn close to the MicroSD maximum voltage...

Anyone knows where to buy?
There is a shop in the USA, but who knows a shop in europe?

PS Why not attache a harddrive to my Tab

Nook Color option
It would be cool if someone could make a Micro SD socket adaptor (with a usb converter cable) that would allow the ability to connect to and drive a scanner and a printer. One would need the appropriate app designed for it too. A nice option for the Nook Color.

Hi there,
I had the mobydapter here, but it didn't function with my galaxy 7 inch tab. Pity I had to send it back. No function beside beeing very unstable by nearly dropping out of my tab. Oh I forgot it was blinking. ;-)

***MOD EDIT*** shows a Mobiadapter attached to a Galaxt Tab 7 tablet.. Somebody said that this doesn´t work on that Tab... What kinda of marketing.. Argh!

The Mobiadapter no loger exist.
Someone know something like that?
Thanks for support

I need this product for a security research. If you happen to have one, even as used, please message me.

[Q] (Resolved) issue with windows seeing an unrooted nook

I haven't rooted my nook yet, but I have run into a peculiar issue. I plugged it into my computer tonight after work, and instead of seeing it as a nook, I am getting 2 removable drives. When I click on either of the two removable drives, I am asked to insert a disk into the removable drive.
When I open the Adobe Digital Editions software (to put Google Books on my nook), it no longer sees the nook, either.
Any thoughts on why this would happen?
Win7 Pro x64

I have now done a factory reset, data clear, and still unable to see the nook properly. All I get is two removable disks, with no devices inserted, when I plug the nook into either of my computers.

Try inserting an SD card into your NC and see if one of the removable drives stops asking for a drive to be inserted.
I'm assuming the two drives are the internal NC storage and the SD card slot. That's how it shows up on my rooted one. Can't recall what it looked like before root. Next time I reset mine, I'll take a look and check in here.
By chance, do you have an Android Phone device in your Device Mangler?

no, I did not see it.
I was able to resolve the issue, though. I ran through AutoNooter, then did a full reset (after playing around with the rooted version, of course ). After that, it worked just fine. I think it had something to do with the way the VMWare player saw it the first time I had it connected. If I have VMWare running, when I plug the nook in, it shows up as a VMWare Virtual USB device, even though it's not connected to the guest.
Not a big deal, I was able to transfer files/movies/etc. to it earlier today, and that was what I was looking to do.

[Q] Burning uSD without external reader

Has anyone tried burning the images to the uSD while it is inside the Nook Color and connected to your computer via usb? I don't have an external reader with me and I was wondering if doing things this way is even possible. Would it mess anything up in the Nook?

No and yes. If you know what you are doing you could use adb or terminal to dd exsisting images to the microsd. But it is just better to buy a cheap reader and don't deal with the hassle of commands. Just buy a reader and keep your sanity. Since you are asking this question I am assuming that you aren't yet familiar with such things. Neither am I. Please do yourself a favor and read before you try or ask anything. Good luck
Nooking with Encore

Does anyone know if using your Android phone would work? I could put it into CWR and enable USB mount. I can't imagine anything being wrong with that, but has anyone tried it?

Found the answer to my own question. Can't post links but in the nookdevs faq.
nookdevs.com/Nookie_FroYo:_Burning_a_bootable_SD_card
There is a note that says:
"Devices with integrated card readers (cameras, smartphones, the Nook itself) will often not be able to rewrite the partition table and won't make bootable cards. Dedicated USB card readers are ideal."
