I am sure that the SD card functions well.
My device has already had hardreset.
My 4700 cannot detect sd card at the first time I insert the sd card. Then, I take it out and insert the sd card again...After several times, my device do detect the SD card.
when it detects sd card, It functions well with the sd card.
If I take the sd card out, and insert again, I get the same problem.

You can download the US basemap for the 500 at http://www.megaupload.com/it/?d=EJTNQH03 Rename it BASEMAP.MGI Then copy it in the directory "background maps" in the SD card of your 500, by using a SD card reader/writer. Insert
the SD card in your 500 and connect it to your PC; then turn it on;it
will turn on regularly, because the basemap in the card will be
detected; turn it to USB file transfer mode, and copy the basemap from
the SD card to the directory "background maps" of the 500. If you already have the file ..just rename it like I said ..and copy it ..using the sd card in the reader...Than if it is not functional ..just reset it ..and reload the file the proper way by reloading maps..
are you sure its not a miniSD card? if it is then you need to insert it into a larger SD adapter first. if it is SD and it doesn't fit make sure that your computer does accept SD cards. A work around would be to insert it into a device that accepts SD cards like a camera and connect the camera or other device with a usb cable then go to my computer and open the device from there to access the files. you really need to be more specific about your problem if you want a better solution. what kind of computer is it? brand and model? what device were you using the SD card in before you tried to insert it into your computer's SD slot?
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...
It rather sounds like you're inserting the card after inserting the reader into the PC... am I wrong?
As long as the device is detected in the Device Manager (system properties), it should be fine.
Insert the card first, then insert the USB reader. From there, check that you get a drive-letter. If you do, great.. if it's brand new, it may require formatting the disk before you can open it and start putting things on it or using it in a camera.
When you say "no files are detected", i'm assuming you don't simply mean "there are no files already on the SD card"... because that's normal if it's new. =-]
Perform the following procedures when your digital camera does not detect the SD card.
1. Restart the camera
Turn the main power OFF, or open the battery cover or SD card/battery cover to remove the battery. Make sure the SD card is fully installed. Then, turn the main power ON, or insert a battery again and close the battery cover or SD card/battery cover until it latches.
2. Initialize the SD card
Format the SD card with your camera.
Formatting procedures varies depending on the camera model. See the Camera User Guide supplied with your camera for the instruction to format the SD card.
When formatting the SD card, slide its tab upward to cancel write protection.
It is impossible to format the SD card while it is write protected.
3. Check if your camera detects other SD cards (If you own multiple SD cards.)
If your camera does not detect the SD card after performing the procedures 1 and 2, check if the camera detects other SD cards.
If it does detect other SD cards, the SD card that wasn't detected may contain some problem.
