I have a Samsung Galaxy S, model SPH-D700, ver 2.2.1. I cannot mount the SD card. It mounted one time (since 2.2.1 update), and no longer mounts. I had some trouble mounting before the update but could always find a computer to recognize it. I always plug it into the main motherboard USB ports as well.
So this time I tried reboot of the phone. I tried it on a Dell laptop and it doesn't mount there either. Both systems have XP sp3.
The phone is stock, and i don't do development or muck around with it.
Anyone have any ideas?
I assume you have already installed the drivers. Put a checkmark on USB debugging then connect to your computer. Select the "Mass Storage" to copy information from/to your computer to phone or vise-versa.
As soon as you disconnect from the computer your SD card will show up on your phone.
The debugging option is under Settings-applications-development.
I've been having the same problem for a while now. Bought 2 epics in September, one can mount fine, the other can't. The one that can't used to, then it went flakey and would only do it every 5th time or so, now it simply doesn't work. I've tried everything, debugging is turned off. I've tried different computers, different OSs, nothing works. I've tried drivers others suggested you can get off the net but I'm not sure why one needs a special driver for a USB connection that once worked fine, then didn't. I haven't installed anything special to make the other one work. I have the Samsung Kies application on my computer and it stays stuck in a connecting state when I connect my epic. I'm gonna go out on a limb and just say our particular phones are hosed with repsect to mounting.
Where is USB debugging option? I looked thru all the settings.
Like darrenpado mentioned: Settings > Applications > Development
**You need to checkmark this option before connecting to the the computer**
Thanks to Radio Shack the problem is fixed. Go to Settings->SD card and phone storage then select Unmount SD Card. Turn off the phone. Remove & reinsert the SD Card (not sure if this is really necessary). Restart and wala it mounts every time.
Yea you, boo me. For a second there I thought that might work for me, no go. Phone thinks it connected (as it did before I tried this process) but the computer doesn't see it. Other phone works just dandy. I don't get it. Probably should just stop by a store and ask what's up with my dang phone.
Try different usb cords, you will have a 50/50 chance the one that came with the phone will work for data, but will work fine for charging. The Epic seems to be picky about it. Keep in mind shorter thicker cords are better. Normally a good data cord will be less than 3 feet long.
I think it has to do with a weak diode or something , some needing better signal strength and power to work properly.
