I've been having trouble getting my nexus one to work as a mass storage device. I will mount sd and then it unmounts on its on. Tried on 32 bit system and it worked perfect. I can mount in recovery fine and i can use adb fine but not mass storage. I tried installing the drivers on here for 64 bit and it works for a little but if i restart my phone it starts unmounting and i have to reinstall drivers. i also tried installing pdanet and it works but same issue after restarting phone. any help would be appreciated
i've had no issues on win7 64bit mounting it, ive only done it once though, i prefer adb or i ftp files from pc to phone.
Using Win7 64bit here too....no probs...hmm..
Same here using Windows 7 64 bit no problems to report. I copied 3 gig music at one time to the SD and it worked fine.
I had the same problems.
The only way I could get it back to mounting again (and the not-mounting problem hasn't returned) was to:
1) Go into 'Devices and Printers'. (Start Button/'Devices and Printers'
2) Right Click on Nexus One and eject.
3) Disconnect usb cable and reconnect and then try to mount from N1 again...
I was thinking that the problem probably started because of my network mounts and then my usb hub on my monitor with all the card reader options as well. I think my drive letters got a little conflicted.
I had to fixed all that first in the Disk Management.
Hope that helps. I was really frustrated with not being able to mount the last couple of days.
Using Win7 64bit here and no issues. Mounted a few times to transfer music and pics.
i have no idea whats wrong. it works fine on my 32bit laptop. mass storage works in recovery. Its confusing
Manually seek and install driver?
I couldn't get it to work on windows 7 pro 64bit with administrator rights. With a user without admin rights, it worked fine!
I already tried manually installing and i have admin rights on windows 7 64 bit ultimate
there are 2 drivers you have to install from the androidsdk. device drivers and usb drivers. install through devmgmt.msc, browse to correct folders in android sdk to install.
You don't need the device drivers to use mass storage. You just need the usb drivers, which should have installed when you first plugged the phone in.
Have you got the Intel Matrix Storage Manager driver installed on your pc?
I have the exact same issue with win 7 64bit home premium. No problem on winxp 32 at work. Also no problems with my ubuntu 64 bit set up. It also works fine in recovery mode.
a long time ago I called HTC about this, because it happened right after I got the phone in January and the official HTC response was, 64 bit os's are not supported!
I had the same issue. It all basically came down to not "safely removing" the storage before unplugging.
Did your computer flag the micro SD card as not safely removed and does it want to scan it for errors when you plug it in? This was happening to me. Apparantly Nexus was somehow choking on the attempt to "repair" and it simply unmounted the card. One day I took the card out of my Nexus, put it into a card reader and let Windows check it for errors. After that, I didn't experience any auto-unmounting anymore.
Actually I'm lying
Another problem was the underpowered USB hub which I use. If you use a hub, try connecting directly to your PC.
Ironically, since flashing back to stock rom (just fiddling around cos I was bored ) I've just had this issue of Win7 64bit not being able to recognise/access the sd card of my N1. Here's how I fixed it:
1. Plug phone into PC.
2. Turn on USB storage from dropdown menu on phone.
3. Go to Device Manager in Windows.
4. Find 'Android Phone' in Device Manager.
5. Right-click and choose 'Update Driver Software'.
6. Choose the 'Browse my computer for driver software' option.
7. Choose 'Let me pick from a list of device drivers on my computer' option.
8. You'll now see 'Android ADB device' and 'USB Mass Storage Device'. Choose the latter and click next.
Windows should reinstall the mass storage driver and the sd card should mount in windows.
If you haven't installed Android SDK in the past then you'll not have an 'Android Phone' in device manager. In this case look in the 'Universal Serial Bus Controllers and follow 5-8 above but right-clicking 'USB Mass Storage Device' instead.
Note: I'd done a format of my sd card before plugging in the phone so if the method doesn't work try that (assuming you've nothing on there that you want to keep).
^ that's what i was trying to say
I was trying the new version of stickmount to see if I could use it to mount my ntfs drive and was trying out workarounds when I came across a post recommending the use of usb host fix. I ran the app, restarted as directed and voila! Now nothing shows up when I connect my otg cable. I've tried my fat32 hdd which was working fine and a card reader and nothing!
I'd moved from 4.1.2 to the stock german 4.3 rom on my rooted I9305 and paragon's ntfs app would no longer mount my drive so I decided I'd check to see if there was anything else I could do before wiping 900gb's of data and formatting it to fat32. Now I wish I had!
I've contacted the dev and tried chainfire's usb diagnostic app as well as usb host controller - which stated S3C usb host driver not found.
Please let me know your suggestions as I desperately need to be able to connect via my otg cable - my phone has taken the place of my netbook when i travel so that I can backup my photo's and transfer music and movies from my hdd's to the phone. I'm heading out to South America and REALLY need this function back!
I'm running the latest TWRP recovery on stock/unlocked/rooted (Sprint, if it matters). I know our devices don't have the USB Mass Storage option/functionality by default, and I certainly don't mind MTP for regular everyday usage. But obviously, when trying to mount USB storage in TWRP, it says this device doesn't have that capability. Any solution and/or workaround for that? With both of my previous devices, the E4GT and the Nexus S4G (which both used USB Mass Storage as opposed to MTP), the ability to mount to my PC from recovery was a lifesaver on more than one occasion. Any help would be appreciated.

what do you need to mount the sdcard for?
you can also mount it in adb or fastboot i believe if you need to. there are also programs that will let you mount it easy if you don't know how to mount it manually.
Hello guys
Recently i had to connect a USB drive ( Kingston 8GB pen drive) to my phone ( Xperia Z3C) but nothing happend. So i said "hmm maybe there sth wrong with my phone" so i tried to mount it on my Xperia Z Ultra, but again nothing was mounted. The pen drive was NOT mounted as it should and I also coudnt do it manually from the Settings( because the options "Mount and Unmout" were grayed out). This is pretty weird. I used to plug in pen drives, external HDDs all the time back when i was on KitKat. But i havent tried to do it since updating to Lolipop .... till now. I searched so long for an answer but i coudnt find anything Confirmed so i decided to ask you guys
My question is : What is the reason for not being able to mount USB drives anymore ? Is it the android version (Lolipop) or Im missing sth ?
Facts :
- i have an OTG cable ( even 4 of them, they are all in perfectly working condition)
- my USB drive is completely fine ( i tried with 4 other flash drives with the same result - not being able to mount them)
- my phone(Z3C) and phablet(XZU) are working perfectly and rooted with latest firmwares. I used to plug in USB sticks all the time back when i was on KitKat.
Help me understand what's happening pls
Are these stock roms on your devices, or are they custom roms? lots of custom roms debloat the software that's installed, sometimes removing the bigger packages not used so often.
Presumably you can see the file structure on the phone/tablet when you hook it up to a PC? so the lead and USB libs are working.
The only other thing I can think of is that NTFS might not be supported in Lolipop, have you tried formatting one of the drives in FAT?
all roms i have are stock
my USB sticks are all FAT32, my external HDD is in NTFS. Neither work.
Yes i can see all files on my phone/phablet through the PC when i hook it up.
I have a n920p and recently ended up in bootloop after trying to install Xposed framework. I do not have a rom back up saved on my internal storage. I can only go to TWRP and Download mode.
When I plug into my PC it reads the "USB device not recognized". I have the Samsung drivers installed.
I also purchased a USB OTG drive and attempted to use it in TWRP, but when I try to select the USB it reads "0 MB".
In summary, I have no working rom/OS, I cannot connect to my PC with the USB, and I haven't been able to access the USB OTG.
I am at a loss. I apologize in advance if this is elsewhere. I have searched xda and google and cannot find direction.
