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.

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

Storage card disappears after connecting to PC?

Hi,
Recently got my t-mobile version of the diamond2, the Compact V.
I was used to the diamond, which flawlessly functioned as an external disk whenever i connected it to my pc.
When i connect the diamond2 to my pc, i can choose the option 'connect as external disk drive'. From my pc, i see it but cannot access the files (it looks empty). After disconnecting the cable, on the phone the internal storage card is gone... When connected with activesync, i can browse my storage card in my pc explorer. But also; after disconnecting the cable, the storage card is gone !
Only option is to turn my phone off and on, then my storage card magically exists again... How can i solve this? I still have the original T-mobile ROM (1.39.114.2 NLD)

same problem ! The diamond 1 same problem with the internal storage

I wouldn't say it's a problem. It's most probably a protection mechanism to prevent the card from being written from 2 sources.
Then again.. you could call it a limitation from HTC (or maybe microsoft)

It happend only if you choose Disk Drive. If you choose Active Sync, you can access it

This is a completly normal behaviour, and as far as I know, other phones do it this way too (Nokia's for example).
This limitation is not directly related to Microsoft or HTC.
The filesystem can not be 'mounted' to two systems at the same time.
For this reason, the phone will 'eject' the storage and act as a cardreader for the memorycard.
The reason you can access your Storage Card using ActiveSync has a reason. When you are using ActiveSync, the files are send to the phone and the phones writes it to the storage card. This has it's advantages and it's disadvantage.
Advantages:
- Memorycard will always be available for your phone
Disadvantages:
- You need ActiveSync installed on your PC
- Copying files through ActiveSync goes much slower..
The diskdrive option is much faster, cause your pc is directly writing to your memorycard and does not need a driver/software to work.

Inconsistent trouble with SD card writing

Hi,
I bought a SanDisk 8GB class 2 micro SDHC card and I noticed that
it behaves strangely in the SG.
When writing larger amounts of data (100s of MBs) I get write errors.
When eg copying from internal SD (/sdcard) to external (/sdcard/sd) with
a filemanager or a backup program.
When connected with USB to a Win7 computer I can verify the disk or do a low level format, no problems. When I copy large amounts of data however, the SG hangs and I must reboot it.
When I put the card in an adapter and mount it on a Win7 or Linux system then I can hammer it with data transfers and all goes well.
So it is SG related and I'm using the stock firmware.
Bad contacts in the SG are unlikely, because once the data is written in the adapter it can be read without issues in the SG and the same contacts are used for writing and reading.
Looks like a driver problem to me.
Anyone else had these kinds of problems?

I have exactly the same problem with a sandisk 4gb class 2. I did not find a solution yet

I have that problem. I believe its got to do with how much power the sgs drains from usb port. I fixed my problem with a powered usb hub. So try that, it fixed alot of usb connection porblems too.

[Q] USB Mass Storage Issue

Hello everyone, I have been using this forum for a while now, but havent really posted anything much as I have always found answers to any questions through searching the threads, however, I am unable to find a solution to a problem I have just recently encountered and was hoping someone out there may be able to shed some light on it.
I am using an unbranded handset running JPO which has been performing superbly until today, however, when I connect the phone via USB to my PC and select mass storage the computer does not seem to recognise the phone is plugged in. The strange thing is it worked perfectly before and the only changes I have made since was upgrading the micro SD card to a 16 gig one. I try unmounting the external card and even removing it completely to no avail. I have tried the phone on 3 PCs now, even my Linux PC does not recognise it.
I have rebooted the phone, tried connecting selecting Kies mode instead of mass storage, all to no avail. As soon as I connect the USB to the computer, the phone recognises the connection and asks what I want to do, I select mass storage, then I get the option to mount via the little green android, which turns orange stating it is connected, but the phone just does not show on the pc.
Any ideas would be most welcome, I don’t really want to have to format the internal memory but I think I may have to.
Many thanks in advance.

Additional:
I seem to remember on Eclair that I was able to unmount the internal sd card in the settings menu, however, with froyo, I only have the option to unmount the extrernal sd card. Would someone running JMO be good enough to check and see if they have the otion to unmount the internal sd?

Right, I seemed to have found the problem, so for anyone else who has a similar experience, it was the USB lead. SGS working as it should agian, phew..

Lumia 521 SD Card Boot Problem

So I have a 64gb card in my phone, everything works fine on it except on boot it says there a problem when there really is none. All my music and files open just fine. Another issue I have is that the USB transfer rate is slower than 1.1 so any time I want to put new music on in have to take the card out and use an SD card reader to put new files onto it. Often times when transfer via a cable to the phone it just locks up mid transfer. How do i fix both the SD card problem boot message and the horrible transfer rates and lockup via USB?

Same issue on lumia 820.

Its possible that the master file table is dirty and the MicroSD needs formatted, but I'd use the Panasonic SD card formatter (I think that's what its called anyways), as SD cards require special care compared to hard drives.
