New SD card won't mount

**pizza_pablo** · 01-13-2013, 12:48 AM

I bought 2 new 16 GB Kingston Micro SD HC class 10 cards for the wife's and my RAZR Ms.
Both have the same issue. When inserted, the phone won't mount the card.
Error notification received: "sd card is blank or has unsupported file system".
Attempts to format are unsuccessful.
I put each card in my old Droid X GB. Both are recognized and able to be mounted, unmounted, formatted and file searched, on the DX.
I also tried reformatting on laptop, fat32.
I tried the procedure here:

although I was unsure what was meant by "Make a shortcut on your windows desktop and make the shortcut location as (cmd)." and could not see the option to "Right click that shortcut and select 'run as administrator'". I di the next step and it did run thru step, showing a progress percentage, until finished. No luck with this either.
I cannot google find or think of anything else to do. Very frustrating.

Please help!

Wow.. that's very strange. I was going to suggest formatting as FAT32 in your PC, but you already tried it. When you have it connected to your PC, did you try doing an error check to see if it comes up with anything unusual?

Also, when you format it in your PC, make sure to un-check "Quick Format".

I believe the procedure I linked did do a check disk. I don't know what else to do.

Quick format was unchecked. Thanks.

OK, I broke down and bought a SanDisk 8GB Class 4, from Big Lots!, for $8. They had no others.
I popped it into the Wife's M....WALAH! Instantly recognized. Then I put it in my M, with same results.
Go figure.

I'll be installing a 42GB SanDisk card tomorrow in my 1-day old RAZR M. Verizon tech support advised me just to pop it in and don't worry about formatting.

Let us know how that goes and what class will it be?

Did you mean 32 GB?

Indeed I did. Fat fingers are not yet used to this new keyboard display.

Will report. The card is a Class 10.

As long as I'm here, the out-of-the-box settings had an icon for "Tools" in the bottom, fixed row of shortcuts. I accidentally deleted it (somehow), and it seems to be irretrievable. Anyone know what was in it?

This is an amazing phone. The battery has absorbed 23 hours of heavy use and still reads 50%.

That folder just has a few other icons in it like settings and a few other things. All you did was delete the folder. Its not a big deal. All the apps or icons in there are still on your phone. You would have deleted that folder anyway. I'm pretty sure we all did.

Many thanks. I suspected as much, but the new user interface (I'm migrating from a Droid 2 Global) is disorienting at first. Then again, at age 65 what isn't disorienting, eh?

Going from D2G, you must be enjoying the improved battery life on Razr M. I also had D2G previously, and even with an extended battery, it wasn't anywhere near as long lasting as Razr M.

The 2G did yeoman's service. I never carried a charger, only a slim extra battery. With the RAZR M, the big leap is in processor speed and the Verizon 4G LTE speed. I was able to carry over my unlimited data plan to the new phone.

Am happy to report the 32GB SanDisk card was instantly recognized upon insertion. No formatting was necessary.

What class is your card?

**magnes** · 01-20-2013, 09:20 PM

Class 10, but the phone also reads the class 4 32GB card that was in my Droid 2 Global, which was never formatted. (I doubt the D2G was reading all 32GB.)
