I should say, once I updated my Motorola files on my computer, I had no problem with the SD card being visible.
lwags67,
After updating your Motorola files on your computer is anything "visible" other than what I posted in Post #5:
Internal storage/DCIM & Pictures
SD card/DCIM
The issue of the OP was not to make visible; but to have access as "Mass Storage" like we had pre OTA JB update.
Effectively be able to transfer and manage files directly on the phone (Internal & SD) from a computer connected via USB (No Moto-Software involved).
I assume when you write "Motorola files", you are referencing the USB Moto-drivers to your computer?
From here:
USB and PC Charging Drivers - Motorola Mobility, Inc. Rest of Europe
Or here (USA):

OR maybe or the MotoCast Software for USB Syncing and/or Wireless ...?
KevlarBack,
I previously tried what you referenced as solution on your device "Developer Options" & "USB Debugging" and these settings changes still do not allow me to see and/or transfer anything other than photos when in Camera (PTP) mode on the phone. PLease confirm are you able to access Internal Memory and SD-card for contents beyond photo as previously mentioned? Would love to have anybody confirm JB OTA Running and they can access there documents, etc. via USB Connection?
To Forum,
I spent quite a while online with Verizon Tech and senior level Motorola Tech today till I found one tech who said he had helped a lady a couple weeks ago to resolve this issue by "playing around with a few settings" (to get MTP to allow file transfers). Unfortunately, he could not remember specifics and had not documented the solution.
It has been my experience (relating to Device Manager) that if the device (Razr m XT907) does not show up in Device Manager under either Disk Drives and/or Portable Devices, that I will not be able to access Internal Storage and/or SD-card. Currently, when phone set to Connect as/Media device (MTP) it's not there (only displays as USB device - and with exclamation), and when Connect as/Camera (PTP) it displays under new heading of Portable Devices.
Personally I still believe we (at least I) am/are experiences a software related issue (bug, hopefully to be resolved in maybe 4.1.2 in near future along with maybe some software mod's to help Data Radio signal). That is, I am hoping that Motorola has not by design chosen to not allow users this access as part of the JB Update. I have found a page on the Moto-website that specifically stated that USB Mass Storage access was no longer provisioned, but that MTP should provide ability to transfer files to/from device (one of many new pages upped to the Moto-site since the OTA JB push).
From what I read the Razr HD versions are ending there soak-test of JB, and have started pushing JB via OTA as of midnight last night (12/6). So if this is a software issue, that has gone unresolved, it would me my hope that Verizon and Motorola are gona get a barrage of fresh unhappy folks calling in that are pissed 'cause they lost Mass Storage Access to their SD-cards and Internal Memory locations on their devices. My hope to help push for solution to what we are experiencing (provided it's more wide spread than just a few folks like I).
