[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] Cant write to 128gb mSD card - no root

Hi
i have a Samsung SM -T800 and just recently needed to increase storage. So checked the specs and bought a micro sd 128 gb.
(My device is Not rooted)
When i try to use the default native samsung file manager it complains when i try to write to it. (Unsuccessful)
If i put in a smaller 1gb card its OK. I tried the 128gb in my Lenovo tablet and it works fine it (rooted) and in a desktop.
I tried my favorite file explorer esfile and the time i go to add a file it prompts to accept using samsung native interface but that still falls too.
I formatted it in the tablet and mount and unmount it safely but no joy.
i looked at using sd fix and sd mount apps but they all need root
Running android 5.0.2
i am wanting to root the device but currently the guide does not have CF file for SM-T800

it probably doesnt support a card that big

Yup it does, specs show it can and i even contacted samsung support to confirm before buying it.

So how does USB OTG work on Marshmallow?

Hello! I've got a 64GB USB C drive I'd like to use with my bone stock Nexus 5x. It's formatted through the phone, and I get the notification to explore the device storage. Unfortunately, just about no other app can see the device storage. No file manager except for ES File Explorer can see it. Most importantly, I'd like an app called LocalCast to see the device storage for casting media from the drive to Chromecast and other DLNA players without copying to device storage first. But like I say, they don't seem to see the drive.
Is there any way to get this to work? I'm open to rooting if it would make it work, but this is my first experience with OTG, so thought I'd ask here first.

64GB Sandisk micro-sd, formatted to FAT32 with the phone. stickmount(pro) installed and the card is recognized by every app on Nexus 5X MM 6.0.1. Poweramp & MX Player both do auto scan of the card when inserted. I also have a 128GB card formatted to exFAT, it doesn't get recognized by anything other than SolidExplorer's USB plug-in.
Just go with FAT32 Format and get Stickmount app should do the trick.

Yip as stated above stickmount is required for nexus's if rooted.
Otherwise try a play store search for "otg" if unrooted
https://play.google.com/store/apps/details?id=eu.chainfire.stickmount&hl=en

I see! I kind of thought it would work out of the box with marshmallow but this is very helpful. I just wanted to make sure it would help before I pulled the trigger on root. Thanks guys!

I have a problem with my pixel 2 xl and can't figure out why

My issue is connecting to an usb-c flash drive. My usb-c flash drive is Samsung 128gb. It works half of the time. What I mean is it works when I am home and not at work.
Right now work.
I plug my flash drive in to my pixel 2 xl.
ES file manager comes up
Show my usb drive with capacity then disappear
I got notification bar and pick transfer file
My flashdrive show up and disappear again
I have also tried ptp, midi, charge, and supply power. Same thing happens, show and disappear
I enable developer options.
I tried both enable and disable usb debugger
I tried selecting usb configuration from mtm to ptp.
I have an applocker app. I disable it and enable it.
I disable and enable smart lock
Google tech asked me to use their usb adapter. It works when I am home.
When I am home, I have no issue. my usb flash drive works fine.
I hope this is not similar to that star trek card game that Capt Kirk invented, Fizzbin. It aian't tuesday.
does anyone have any idea I can try?
Maybe I missed something.
maybe I enable something I shouldn't have
I am able to connect to a computer fine.
If I left the usb connected and restart, I get "still rejecting Samsung USB drive. Don't remove."

Hmm... are you saying your PHONE recognizes the OTG drive at home but not at work? Are you rooted and have tried StickMount? Sounds more like a drive going bad or a formatting issue and its just working half the time. How is your drive formatted btw? FAT32? You probably already know Android doesn't support NTFS. Also for the record, ES File Explorer is a serious P.O.S. Do yourself a favor and get Solid Explorer. It goes on sale around Xmas time and is worth every penny.

I do have solid explorer. I need to change the default to Solid. I used my phone to format my flash drive. Everyday at work is the same. Doesn’t work before 4:xx pm and works after that. Today I tried a 256 gb with an adapter and it was working (4:4x). After that i put in my samsung 128gb usb-c and it works. Both doesn’t work in the morning or before 4:xxpm.
My phone is not rooted.

I asked how the drive was formatted, meaning what file system it was formatted to? You said you used your phone to format the drive, but the question still stands... Is it formatted with FAT32, exFAT , Ext3 / Ext 4? Whatever it is, use a PC to reformat it to a different one of these supported file formats. Try exFAT first. The whole "time" thing has no bearing on this whatsoever. It is either a hardware issue with the Samsung or a formatting issue with the drive. Note: please use the "Reply" button so I get notified when you respond.

I am sorry for not responding back sooner.
I tried to format my usb to exfat, but my phone said it doesn't support that and need to reformat it. It reformated my flash drive to fat32

yeah I have a 256GB Sandisk Dual M3.0 OTG drive and my Pixel 2 XL always format the drive to FAT32 and can't support FILES larger than 4GB.
Are there kernels out there that support exFat for the Pixel 2 XL???

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

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.
