Try to format it in exFAT. And is the USB 3.0 device compatible with 2.0?

pretty much. even after formatting it from the phone itself, the same error message repeats and I cannot view my data. But when I plug the usb into the laptop, all my content is intact. which technically means that the phone is failing to format the usb even after it shows the 'Format complete' message. I guess this is a CM Kernel problem

Is it a case of what format your external drive is in? FAT32 vs NTFS?

Pendrive support issue.............

Hey guyz... i have an issue ...need ur suggestions.
I bought the OTG cable to use my 8gb PENDRIVE... Manufacturer: KINGSTON.
But unfortunately when i attach the usb after some time it says USB already remove...
I also tried after formatting the usb using the FAT32 + NTFS option but the problem remains the same.
On the other hand i tried to connect HP 4gb and no problem occurs with them....
I also tried to check it with h2testw no issues reported.
I also used the software Paragon NTFS & HF from play store.. ISsues are the following attached images.

It might be a compatibility issue with the Kingston pendrive.
Previously saw a forum posting saying Android OTG is more compatible with FAT32 pendrive.
First time hearing FAT32 + NTFS option.
1) You can try to use Windows to format the Kingston pendrive to FAT32 format.
2) Or use App SanDisk Memory Zone to format the Kingston pendrive.

3) Sony is going to sell a new 2 in 1 flash drive, you might want to consider getting it

It's have two partitions? Then is that the problem.

I also contacted the Kingston customer support... They are saying that all usb's are standard and not OTG supported so far.. .So no use of discussion... But still if got any solutions then let me knw.. Thanks in advance...

How to use OTG in TWRP?

Hi guys,
I installed the latest TWRP in my phone, when I tried to backup my ROM I noticed there is an OTG option, I've an Y-Cable, so I formated my usb drive to fat32 and plug in together, I rebooted the recovery, however nothing works, can anybody know how can I make backup to external storage? Thanks!!
1. Reboot to recovery
2. Plug in otg device
3. Go to mounts and mount the otg device
4. Go to backup
5. Hit the bar below the check boxes that says internal storage
6. Change to Otg
7. Backup as usual

Hi Red,
Ive already tried your options. However the otg device was showing 0mb in the mount menu. I've already formatted to fat32. Which otg cable type are you using? Does our device need external power?
It works with my otg cable with an old 512mb thumb drive in it. It also works with my 32gb Micro USB thumb drive.
You may have to hit the refresh sizes button to see something other than 0mb

I changed my otg cable to the traditional one (not the Y-Cable), it's working now
However, there are some weird things happened on my usb drive, I have two Kingstone DataTraveler usb drive and both of them have 8GB space, same model same space, same fat32 format. Both of them can be recognized by my computer, however only one of them can be recognized by my phone.
Try plugging in while the phone is running and format with the phone

Which OS are you running? Did you try a different USB drive/OTG cable?
In Lollipop 5.1, it automatically mounts USB and you can access it in file manager (I use ES).

I am using cm 12.1 official and USB drive. I tried my friends usb drive its working .the only problem is with mines only.
And that also i done clean formatted with fat32 so many times still it is not able to detect in phone but it is working in pc perfectly...
That's very strange. Could you please try a full format to NTFS?
And what is the capacity of the USB drive?

i tried that also but no use.. And pendrive is sandisk ultra 16gb dual
I believe there is some problem with your dual USB drive. I have Sandisk Ultra dual 64GB and mine works fine (I own Moto G 2nd gen, but there are not much hardware differences in 1st and 2nd gen). If it is in warranty, maybe you should go for replacement.

how to expand storage in CCwGTV?

is there a way to add more storage to google chromecast with google tv? i've tried many methods to have CC recognize my 128gb usb 3.0 fat32 flashdrive. I've gotten a usb c hub adapter with ethernet port, i've plugged the fat32 usb flash drive, formated it in google tv as internal storage, google tv sees the flash drive but i won't allow me to use it to transfer files, use it as extra sotrage etc etc. Anyone got a work around? I've factory reset this device but no luck.

yes i formated it using my windows laptop to fat32, then plugged it to the usb c hub, formatted it again using ccwgtv as internal stoage but still can't use the flashdrive for anything. If anyone here was able to expland their CCwGTV, please post the steps here. Thank you.
I used an old 16GB USB 2.0 stick, formated with AOMEI on a windows laptop, inserted into a USB type C hub to my CCwGTV and now in
Settings/Storage
in the internal storage I can see the 4,4 GB original space plus the 14,8 GB usb stick.
I also own a 256 GB USB 3.0 stick, inserted into the USB type C hub's second slot, which is presented as "External disk" in the storage menu.
