IMPORTANT G1 Question need Help now!!!!!

The C340 works with MMC and SD cards. Your new 4GB card is actually an SDHC card. While it fits into the slot, it will not work with devices that haven't been specifically designed to work with SDHC cards. You will need to stay with SD cards, 2GB and smaller.

If your SD card cannot be formatted and your phone cannot read it, you will simply need a new SD card. That is the only fix.

Try cleaning the pins of SC Card with contact cleaner or alcohol if you prefer make sure its dry enough before inserting. If nothing happens try detecting it on PC Desktop with proper Card reader, backup files if you still can then reformat thE SD Card. Reinsert in your HTC G1 if successful reformat it again using your HTC G1 to acquire compatabilty on the device.. hope this help...

I had the same problem. so what i did is i created a back up on my computer and format it the sd card. and it had a bad file in it that was causing the problem. once i format it the card it was ready to be used again. just make sure you look for that corrupt file so you don't put it again to the already clean card. also i removed the sd card from the g1 and plugged it straigt to the computer. I hope this can help you like it helped me.

Reformatting will not help you and will lose everything on the card. Furthermore, do not attempt any repairs or data recovery until all other options have been exhausted. Have you tried the card in another Mac? Does a simple drag and drop action to your desktop work, or do you get the same or similar message?

Make sure the computer is hard-rebooted and attempt to import pictures from another card. If it fails, problem with program. If it succeeds, problem with card, but this does not preclude trying the above-listed options.

if reemoving and reinserting the card doesnt help, youll need to have it reformatted....

do this by connecting your phone to the pc and opening your MY COMPUTER icon > right click REMOVABLE STORAGE/DISK > select FORMAT

**if your computer says something like 'no disk available' try disconnecting the device and select MENU > SETTINGS > SD CARD AND PHONE STORAGE > make sure the check bos for 'USE FOR USB STORAGE' is checked****

after that, set the 'file systems' as FAT32 > select START > read the warning > press OK > once complete, disconnect from the pc and try again!

IF that doesnt work, try to test the sd card in another phone to see if the sd card itself is the problem. if you still have the issue but the sd card works, go ahead and reset the phone.

MENU > SETTINGS > SD CARD AND PHONE STORAGE > FACTORY DATA RESET > RESET PHONE > ERASE EVERYTHING

For those with the 4 GB model, try removing the SD card and powering completely off, without selecting any of the recovery options.  You will probably get prompted to recover when the device boots, click OK to recover - do not reinsert the SD card.  Perform a complete power off and power on cycle without the SD card.  If this works, reinsert the SD card and perform a power off/power on cycle.  If it prompts you to recover the system, the SD card is bad (the data can probably be read by the device after it has restarted, but will continue to cause the recovery mode).  Note that reformatting the card in the device does not seem to resolve the issue.  Try reformatting the card in a PC or digital camera (this option worked for me).
