USB Xfer failure to phone, Infamous v3.6
So I've had a bit of a 2 part problem here. I flashed Infamous v3.6 a few weeks back on my S4, and everything has been flawless... Except for 40% of my apps fail to recognize the properly mounted 16GB MicroSD that I have in the phone. So, I attributed this to the ROM not handling the card properly, "oh just a bug in a custom rom". The OS itself, as well as file manager, etc, all see the SD Card just fine. But certain apps won't pick it up, I.E. photo collage apps, hungry shark, etc.
So I downloaded a bunch of ROM's today, going back to AOKP and a different TW ROM, etc. Set them all on my desktop. Stripped all of the files off my External SD Card to clean it up. Thought maybe, before flashing a new ROM, using the reformat SD card that's built into the S4 under options may resolve the issue.
Did the reformat, didn't solve the issue.
Now, I'm trying to xfer my downloaded ROMS to the phone, and the 1.5 gb file completes, but cuts it short ~1.3 GB (no way I'm risking flashing that), but some of my smaller AOKP roms won't transfer.
Spits up the "Cannot Copy Item: The device has either stopped responding or has been disconnected" error. This happens when trying to transfer it to the external SD, or internal memory. Gapps/Photosphere transfer just fine (much smaller zips).
Does it have to do with the way the card is formatted now and what file partition this rom supports?
That being said, how do I reformat it? Considering MTP/PTP don't support it as a "drive" that is reformattable via PC.
BTW, running Win 8 with the newest Samsung USB Driver.
Any help would be greatly appreciated, I can't even flash a new rom since I ripped my older downloaded roms of the SD, and I can't put new ones on
