[Q] “USB Storage damaged. It may need reformatting” error message on OTG

Hello everybody,
I have the following problem appearing recently:
Whenever I connect a USB stick through OTG cable to my Galaxy Note II I always receive the message “USB Storage damaged. It may need reformatting” in the status bar, no matter which stick or other mass storage device I'm using. On my PC, the files are perfectly visible.
I didn't tamper nor change anything on my phone, it's been running the original Samsung ROM, rooted but otherwise unchanged, for the last six months.
Could any of you help? I explored several threads with reference to the same error message on other Android devices here and in other Android forums but none of them matched this problem.
Thanks in advance!

Hi,
Have you tried smaller sized USB sticks?
Because my 1 terabyte SeaGate hard drive works but turns off because it needs more power.

Yes, I tried with a 1GB and a 4GB sticks that worked quite well on OTG last week.
Both these sticks still work well on my PC.

It wasn't.
I did tick it but it doesn't change anything in the behaviour.
(BTW, thank you for taking the trouble to help me!)

No problem helping :highfive:
Well, I had no problems with USB OTG yet (except the 1 tb)
I suggest you factory reset or change the OTG cable.

I tried the cable as well...
Factory reset is a bit radical.
Does anyone else have an idea?

solution
Hi I had the same problem. I found the solution myself. Android doesn't support NTFS format actually. Format the USB with fat32. There u go. :good:

Use NTFS mounter app.....it needs root....

The problem is caused by kernel and USB drivers. Depends what kind of ROM is installed on your phone.
Some of the ROMs dont recognize big variety of card readers. Now I am using some cheap china phone,
so i had hard time to find the correct SD card reader.
Before, I was using Paranoid Android on Nexus 7, I didnt have problem with mounting any size of card, any kind of card reader.
Try different card readers , play around, you will fing the way.
:good:

I have the same problem but both the cable and drives work fine on my Verizon G3 but not on my T-Mobile G3 running 6.0.1 mm based Turbo ROM.

My S5 suddenly refused my Usb Otg drive for no reason. It was working fine. It also corrupts the drive so BE VERT CAREFUL before connecting any mass storage to Android. Why is that?

[Q] USB-OTG failing?

So i got my cable in the mail today, installed stickmount, but when I hook it up to the n7 i get a message in the status bar saying "Blank USB storage: USB storage is blank or has unsupported filesystem"
I reformatted the usb drive in windows and am still getting the same message. Clicking "format" from the message results in a random reboot. This is odd because when I plug it into my htc it mounts just fine. Could this be a ROM or kernel issue?

What format did you format it to? Stickmount can't read NTFS natively. There is an add-on to allow it t to do so. If you formatted NTFS, try reformatting to FAT32.

Formatted in FAT32.

Ok. FAT32 & Stickmount work fine for me. NTFS works as well with the add-on. Not sure I have a suggestion. Probably need to have a bigger gun than I check in on this. Sorry.

Just tired NTSF, came outcome.

You DO need the add-on for NTFS. Won't work with without it. FAT32 should work, though.

Chcek, 've placed all the add-ons in my internal. Still doesnt work. The fact that it works on the phone but not the tablet makes me wonder if its a ROM or kernel problem.

I am on stock (jss15r, but it worked on 15q, too) and rooted (obviously).

Guess I'll just hold tight and see if future updates to ROM and kernel resolve it.

Possibly someone else can help.

Working Method to Read NTFS? Tried some but no luck.

I researched for ways to make 10.1 14 read any external HD with NTFS format thru OTG.
Found a couple of ways, tried and it still show me empty folder.
Tried both Stickmount and [root]Ntfs Mounter and both doesn't work. It tried both of them with my 3 HDD (256 GB SSD, 1TB and 2TB WD Passport).
I was hoping to connect it without having to reformat any of the disk to ExFAT or FAT32.
Is there any method that's working yet
Really appreciate the help. TIA.

Hi,
There is only one working solution as I know.
You have to install TotalCommander and then also the relate USB plug-in.
The only limit is that for NTFS is read-only.
For all the other programs you find on the store for OTG management, are not working because of the restrictions made by SELinux in enforcing mode.
To solve this, you have to find a working custom kernel that sets SELinux in Permissive mode. But as far as I know there is nothing for sm-p605.

Thanks for the response. So that's why everything that I'm trying just tells me its mounted but doesnt show me anything.
I was hoping to use it as OTG storage so read-only seems pointless at this moment.
I guess we wait right Thanks again sir!

AFAIK, bindroid kernel is coming with NTFS support, limited to SM-P600 and SM-P601.

Since about two days there's a new version of Stickmount, which will during the first run download additional stuff to enhance compatibility. I would suspect an Ntfs driver.

without ntfs drivers in kernel, you cannot read ntfs format...

[question] USB OTG

Hello all
Did any of you managed to get an usb flashdrive working on TWRP?
I tried two different devices, and none of them worked on recovery as OTG drive.
However... all my computers and MIUI itself, detected the usb flash drives and performed data copy with no issues.
i tried to change the filesystem on the drives to exFAT, FAT32 (default) and NTFS... no luck. Rebooting to twrp with the flashdrive connected or disconnected doesn't make a difference either...
Providing any help, idea, tip or usb make/model you may tried before with success is appreciated.
thanks and regards

I have no problem with USB OTG in TWRP.
Kingston 64 GB USB flash drive formatted to FAT32 with generic OTG adapter...
Can you provide recovery.log in order to analyze the problem?

Hi - thanks for the answer.
I will be glad to provide recovery.log - if you can help me out with it.
I checked over the file system and didn't find it. Thanks

When you are in TWRP, plug the USB, try to mount it (it will fail, yes, but this is important). And then go to Advanced menu -> tap the Copy Log button. Your log will be on /sdcard/
You can post it here, or on sites like pastebin.com

funny thing... after a third format... it started to work. for the very same reason it didn't work before...
anyway. thanks for your time!

It can easily read more than 32GB, without doing anything. (In Fat32 of course)
Or if you want to use NTFS but without Root, check this out

If i am not wrong, maximum for fat32 is 4gb filesize?

You don't need to install any module to be abke to access fat32 formatted device, hell you don't need to have root at all. Fat32 is recognized by the system as is.
You just need a working OTG cable and use MiXplorer (download it from XDA official page). You will see your thumb drive in the hamburger menu (first or second one).
I have non rooted firestick 4k and it works.
I have no experience with fos5 devices and i cannot say anything about that because most NORMAL commands don't work there

NTFS and ExFAT file systems are developed by Microsoft.
Amazon is not paying to Microsoft for the license to use NTFS and ExFAT.
The maximum file size for NTFS and ExFAT are 16EB (exabytes) or 16 million GB (gigabytes).

Hey my device is the way I want it now sween wolf, rooted with all apps installed, I can't be assed unrooting it now.
but anyway I flashed the magisk module with the general thought being if I was using a pre-rooted rom I would lose the ability to use the USB drive through OTG?
So I flashed Pretorians module but I can't get the USB drive to show up, it's a sabrent 32 gb formated to fat32
I'm using a similar app to xplore called filemanager plus but with no joy... The USB storage just isn't playing ball and showing up you know?
So I don't need the module at all? , should I perhaps try reformatting the USB?

I am not telling you to unroot, this is not something rooting a device kills, but yeah with or without root, usb works.
Try changing your explorer, use mix or es file explorer to see if the usb is getting recognized but isn't showing up

My english is not perfect so i still not try this before i will be sure.
What is easiest way to enable ntfs or exfat usb drives?
I need this for Kodi, so i cant use es file manager.

File System Functionality Comparison - Win32 apps
Tables that list functionality and feature support comparisons for the four main Windows file systems, NTFS, exFAT, UDF, and FAT32.
docs.microsoft.com
so fat32 max filesize is 4gb, you are right
and that is the reason users need for higher resolution movies bigger than 4gb ntfs or exfat mass or some NAS to circumvent the limitation for local mass storage filesize of fat32

It absolutely is. The maximum file size for FAT32 is 4GB. What you linked to is exFAT, which is NOT FAT32. exFAT also cannot be read by the firestick.
