my computer sees this as an external drive but still says insert disk in drive d? some colleagfues say the pc cannot read that size of the card and requires a bios update????? any ideas what they are talking about and how i fix this problem
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 !!!!

Topic exists, fella.

So the Diamond has USB Host?

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,
jeffrey

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,
Jeffrey

Obvious, but still nice!

He, Just thought that I would try and let my PS3 act as a charger via USB for my Diamond, and of course it works - and as a bonus, you are able to access the Internal Storage as a USB disc (Fat32 format) and may play whatever mediafiles are on the phone...
I know, its obvious as its just a USB device, but still - very Nice

Coool Same on the 360!!

My Dad has a cheap DVD player with a card reader and a USB port on it, unfortunately we live in different countries so I can't test it right now, so does anyone else have one of those? does it work? Thanks.

[Q] External storage and the nook

So I'm brand new to the world of tablets and Android and whatnot (and, subsequently, this forum, so sorry if this is a dumb question). I'm trying to decide between buying a nook Color (with the intention of rooting) and the Archos 101. I prefer almost everything about the nook, but the 101 can connect to an external hard drive, and that's a big deal, as I'd like to be able to access my documents and video on the fly.
So, with the proper USB adaptor, will the nook support external storage? Thanks!

The hardware should allow it, but AFAIK it doesn't support it out of the box. It shouldn't be TOO much trouble to allow it to. shrug.
others will know much more about this.

Yeah, I'm not expecting it to work pre-rooting. I'm just trying to figure out if I'll be able to access the external using a file manager.
Thanks!

Ok, don't quote me on this, but I (think) i remember someone somewhere (not very convincing...) stating that the usb hardware was capable of host and OTG modes.
Android is most definitely capable of dealing with host mode, which is necessary for usb hard drives. So there should be some way of enabling it....
Sorry I'm not much help... I'll do some research and see if its a hidden toggle somewhere, otherwise I'm no help. lol

Any update on this? I'd really like to buy a tablet... but I need to make sure that the hardware can support it.. even if rooting is necessary to make USB port into Host.
If it can't does anyone know of a tablet within the $200-300 range that has USB host capabilities? Would like it to have a separate port for power while USB being used specifically for my 1TB Western Digital My Passport external USB HDD.

Do you actually have 1TB worth of info that has to be accessible on the fly or could you just load what you regularly use onto a larger sd card? I know this isn't an answer to your question but I just wondered how many gigs of documents you have to have access to during the day because the NC can use up to a 32 gig mSD if I remember correctly.

[Q] Galaxy tab Usb and SD connection kit

I bought that product last week and got it 3 days ago.
Well the Usb connector is cool if u want to use a regular keyboard or a memory stick
It does give power to my usb headset, but sound keep coming out from speakers
It doesnt give enought power to my usb Goflex Freeagent external Hard drive
As for the SD connector, well here come my questions since i didnt have any SD card nearby and i want to know before buying one.
Can I put my titanium backup/rom manager backups on an external SD card ?
Can i put Movies on the external SD cars and then watch them on my tab ?
I ask this last question because i got quite a few games that are taking lots of internal space and i only have the 16gb tab. I like 720p movies but they weight around 4gb and thats pretty much all the space i have left on the tab so i though i could put them on an external SD since my external HD cant be plug into the tab.
sorry for my poor writting skills, i hope u guys understand what i mean

please i need help on thoses two questions

I had similar questions, but apparently these aren't the forums to ask them.... sigh

Where did you purchase these gadgets at???

You should specify which tab you own.
Here is the 7" (1st gen./classic) tab forum and there is (sadly) no official Samsung "Usb and SD connection kit" for our tabs.
Hardware wise it should be possible to use kits made for the current 10.1" tabs, but there is no OTG (USB On The Go /host-mode) support in the ROM.
Regards, Juergen

..... this is the second subject i start in the wrong section
but since some of you read it here, i will anwser here and starting a new subject, so if we dont get any anwsers here check THERE!!!!
Yes i got the galaxy tab 10.1
yes i got the official samsung usb/SD card connector kit
I tried to read a movie from a memory stick plugged into the usb connector that was plugged into the tab and it did work but, video player like moboplayer arent flipping the screen, this mean that the stick and connector are in the 30pin connector wich is at the bottom of the tab so u cant watch a movie with the tab standing in the portrait position (see picture)
Do you guys know a videoplayer that will rotate the screen so my sd card or memory stick would at the top ?
