[Q] HARDWARE or driver problem???? microsd card not seen

I've tried to avoid asking a stupid question. Have spent all day mucking around with a7. Have installed 2 updates via micro sd. was successfull, but still had bugs. I have Dexter v1.2 on now and wanted to do 1.3 but a7 WONT MOUNT SD....DOES NOT SEE IT....have tried 2 cards, one had previously worked....both are 8 gig 32 FAT ...BOTH were reformatted several times. windows 7 can read cards, but not A7. Almost seems like a driver corrupted OR??? How can I get A7 to see sd??? cant update without it....DAMN frustrating...dont want to send back machine...like it.

Thanks

you neeed an sd adapter

You A7 isn't broken Dexter has an an explanation for the SD card look for it.Use a SD card adapter connect to your PC then to your a7

this is not helping

Any ideas re how I can get the a7 to read the micrsd card would help...It worked before and I was able to flash ...but now will not see any files or mount any card so I'm unable to re-flash. Ive done all the reformatting on the microsd to FAT32, and have tried 2 cards ...no luck..
Any suggestions would be appreciated...,

/me thinks we need to start a stickie regarding which cards work and which don't.

Make sure that you're using an 'SDHC' card.
There are several posts lately regarding problems with standard Micro SD Cards
not functioning properly. -=- LINK -=-
It seems that the reader only likes 'SDHC' cards and not standard 'SD' cards.

Let's start listing the specs of cards when posting, perhaps we'll start to see a pattern.

Still need help

BOTH CARDS I used are SDHC and worked previously but now the A7 doesn't see(read) card after they are in slot...so I'M UNABLE TO RE-FLASH. I'VE re-formatted them (FAT32) and downloaded dexters 1.3. work fine on PC but NOT on A7....ANY IDEAS OUT THERE???

Micro SD Card Problem

I had the same experience. A7 used to recognize my micro sd card but when I changed to Dexter's 1.2 A7 does not recognize the card anymore. However, what I noticed is that the A7 still is able to read my MUSIC and PICTURES that are all in my micro sd card. I know that because if you go to your pics and music the A7 still shows them all. But if you go to SETTINGS - SD CARD AND DEVICE STORAGE SETTINGS......It says " MOUNT SD CARD (Insert an SD card for mounting ). Why would it say that when my card is in there? Also I just purchased an 16GB usb drive and that too is NOT recognized. Any fixes to this problem? Thank you very much!

It's very strange. Who has extra experience to get output from "mount" command in terminal emulator???
May be sdcard mounted wrong...

Bring up Terminal under Dev Tools and just type 'mount' & ENTER
(hold down the MENU key to bring up the keybd or hook up a USB Keybd)
Then hit the MENU key and you can email it...

SD Card

There are numerous references to this issue in other threads. Dexter has responded and states that it is I believe a driver hardware problem with eLocity. I cannot "mount" the card either but if I go into any number of file managers I can see it, read it, write to it, etc. The OS does not recognize it for the purposes of putting apps on it, etc. And yes, video and music apps do see the card and play from it. I have had no problem with this.
I recently had a problem with a new micro SDHC card but I attribute it to being defective since I have a 16GB one and it works fine, I also have a 4GB and it also works fine. Also external drives I plug into the USB slot are recognized for reading, writing, etc.
