[Q] Mount USB storage is coming up empty - Xperia Z Q&A, Help & Troubleshooting

Howdy. I have plugged my thumb drives into a mini converter, gone to "storage" -> external USB storage and is saying its empty. I click the empty message, and it asks me "Format USB storage - are you sure you want to format the USB storage? All data in it will be lost?"
I have tried several thumb drives (fat32 and NTFS) with stuff on them, and I get the same message. Why aren't my files being seen ? Please note I am not tech savvy, so please be gentle. Cheers

Mass Storage Driver? (USB Flash Drive?)

Hey has anyone gotten a mass storage driver to work on the G-Tab? Or something similar?
Want to be able to take files off of a USB memory stick (or my external USB drive for that matter) but the table doesn't recognize them when I plug in.
Thanks

I've been using an 8GB USB thumb drive with my G-tab and it reads the files on it just fine. I think it has to be formated to fat32 before it will read it though. Someone correct me if I'm wrong.
I do it daily with several different thumb drives. Use esfilemanager and hit the flashcard-looking icon and look for a folder called USBDISK. Your stuff is in there.
FAT is standard for most flash drives and you should leave it that way for compatibility, but you can format in FAT32 also. NTFS or exFAT won't work for flash drives on G-tablet. Also don't try to power an external hard drive from that USB port, not nearly enough juice.
(Use FAT32 rather than FAT if you need to put video files or something larger than 2GB on the drive, limit is just under 4GB for FAT32)
I know there are people using NTFS on some ROMs but most users won't have the chops to accomplish this.

Okay, so how do I read/write to my nook's SD memory?

I have a Nook Color, and I made a 4gb SDram that allows me to book to Android 2.3. It is possible to plug that thing into my PC and read/write to the free space on the SD card? I tried plugging in a generic Micro SD cable, and it comes up with 2 drives that it says are not formatted.
If you used the "size-agnostic" instructions or a derivative, then all you have to do is plug the charger cable into a PC.
Two drives will appear, one that's your /sdcard partition, the other is your /emmc partition. They should both be fully accessible from the PC like thumb drives, and you will need to tell Windows when you're done with them, like any thumb drive.
Windows has trouble with partitioned SD cards, and generally doesn't support the ext filesystems Android uses for some partitions; when you plug a card like this into a Linux PC, you get four drives, all fully accessible. Going through the NC exposes only the two partitions that everybody can use.

You can but only able to access it via usb cable plugged between your NC and your PC.

Cannot mount as disk drive

When I first got this phone I could plug it into USB and mount as disk drive, and the internal and external storage would pop up, now they popup in mycomputer as drives but I cannot browse the contents, I get a "please insert disk" like when you have a cheap card reader plugged into your computer with no card inserted
Anyone else know how to fix this? I can no longer dump photo's off via usb
it appears as though, if when I connect the USB, I tap the "mount sd card" button several times it starts working weird

USB Mass Storage

Is there a way to mount the SD in mass storage when connected to pc? transferring lots of files normal way takes a vary long time
Yes, with the USB not plugged in go to Settings/Xperia/USB connectivity and the options will be there. You can only mount the external SD card as MTP though.
Thanks :good:

[SOLVED] OTG support for large storage

I am trying to get large SD or microSD cards to connect to my droid turbo via an OTG adapter but have not had much success. I can successfully mount a 64GB flash drive and a 128GB microSD but when I step up to a 200GB microSD or a 256GB SD it does not mount. The button in the storage section of the setting to mount OTG storage becomes un-greyed-out but it will not mount it. My phone is rooted.
I was eventually able to figure it out by formatting the drives in FAT32 as primary and with 32kb cluster size. I used minitool to format the cards.
My next task is to try and connect multiple drives at once as well as a usb audio dac.
