Anybody have a problem with an external storage disconnecting and reconnecting endlessly when you plug it in, and then after you unplug it, notifications still keep appearing which say it's connecting and disconnecting? The same storage thumb drive can also plug into the PC - and it always stays connected and doing a check on it from the PC shows there is no corruption to the drive or the files thereon. I have a huge number of files on that drive... maybe there is a limit with the Android OS? Or maybe my phone is trying to scan all the files every time I plug it in and is getting overwhelmed? Any ideas?

I needed to transfer some files from my N1 to my Pc, so I connected it to my PC using the cable. I was expecting the black mounting screen prompting me to mount the SD card, but nothing happened. I restarted my device twice, but the case is still the same. What could have been wrong? I have not installed any app within this time, not removed any. I have used it in just ordinary daily manner, messaging and calling and nothing else. My N1 runs on Froyo, OTA. No jailbreak.
Please help. Thank you
u need to assign a drive letter to your SD card
Noob answer: is it on the status pulldown bar?
Do you have USB Debugging enabled?
Does the phone recognise that it's been plugged in (ie start charging)?
Similar problem
I am having a similar problem with my N1 running CM6 stable. When I turn off USB debugging and plug the phone into my Win7 laptop, I get the USB connected screen, but when I turn on USB storage the SD drive doesn't mount i.e. I cannot see/access the drive in Windows 7. The N1 status bar says USB storage is on.
Under Device Manager, the N1 shows up as Android Phone-->Android ADB Interface with driver version 2.0.10.2 dated 11/08/2009.
Any help would be much appreciated.

No, THIS is exactly the problem, the phone dies not recognise that it has been connected to a computer. It does start charging, but no sign of SD memory mount/unmount. Nothing. Just simply charging.

No, USB debugging is not enabled. I double checked it.
I guess that Windows also doesn't recognize the phone as anything (Device Manager doesn't show anything new plugged in)?
In that case, enable USB Debugging, and see if the phone is recognized by Windows.
If it is - the problem is somewhere in SW.
If it isn't - then it might be a faulty USB cable or connector (from any side - phone or PC).
same thing happens to me from time to time. restart your computer and that should fix your problem.

I'm trying to transfer some movies to the phone. I have managed to connect and both internal and external sd shows up on my computer (mass storage).
The problem is that after a while of transfering, everything freezes and I have to disconnect the phone and restart it. Anybody else with that problem or a solution.
This happens in both XP and Win7.
Not using Kies, however it happened one time with Kies as well.
Need help!!
size, what is the size of the movie
and what is the size of free space on the phone
also make sure it is not larger than 4 GB
and it could be your PC with a crazy USB port like mine, that sometimes just acts up like a girl, and other times works fine
I am having issues with the activation of USB Mass Storage mode on CM7 v7.10. When I first connected my nook (just got it yesterday), I was able to enable mass storage mode as per normal. However, after this it's just stopped working!
There's nothing wrong with the cable afaics because the empty drives come up on the PC (Win7) no problem, it's just that the nook doesn't detect that the USB is plugged in and so never gives me the option to enable Mass Storage mode. I have had success once running ROM Manager's 'Fix Permissions' function, but since then it's not made any differences. The issue remains on multiple PCs with multiple cables.
Anyone got any fixes for this issue?
+ can you wiggle the micro-usb end a bit to see if anything better?
+ do you have the "usb debugging" check?
+ do you see the usb icon displayed on the NC notification bar?
- No wiggling makes any difference
- Tried with USB debugging on and off - no difference
- No USB icon (but empty drives still show up on my PC) so there is some kind of connection going on.
If the empty drives do show up on the PC, it definitely some sorts of connection made, it's a good sign.
Now back on your NC, go into Storage, try to Unmount then Remount the uSD and see if it gets any going.
Note: leave the Debugging USB Mode on.
Might also be worth considering moving from 7.1 to the MiRaGe 7.2 build. I'm not saying there is a specific fix but using the later ROM may help and I think most people find it more stable, faster and problem free.
Yeah, I actually updated to KANG 7.2 this avo and the USB Mass Storage option is back!
Thanks everyone for your suggestions!
I currently having KANG Mirage 7.2 with Tablet Tweak but it did not work. I bought an OTG cable from ebay so I assumed it's bc the OTG cable. The Drive works fine on my laptop but nothing appears on the Nook.
Maybe a re-flash with the same ROM might do the trick?
I'll try to reflash sometime soon!
Will post
uSB mass storage
I had the same issue. Have the USB connected and while connected reboot your device once it has rebooted you'll be able to access the USB files on your device. You'll be able to see the USB signal at the bottom, which you can activate. You'll have to do this most likely everytime you want to access USB storage

I'm on MIRAGE 7.2 running off EMMC. SD card is in the Nook.
I shut nook off, plugged in the cable to my pc and started the nook.
5 drives show up but I cannot access any of them. The USB icon is in the tray on the Nook and it says "USB connected". Just above that it says, "USB debugging connected"
Anybody have any success?
After doing some reading I've decided to use ES-FILE Explorer wirelessly. Its very easy to use. You need to SHARE folders on your PC in order for it to access the files.
Playing around with the USB option some more, I didn't realize that you could TOUCH the message in the notification bar. When you do, it launches a program and from there, you turn the USB connection on or off.
Geeeeeeez........ya learn something new every day.
using windows XP i can not get the nexus 7 to show up to transfer files. not sure if i need a MTP driver (which i cant find anywhere) or if there is something else i need to do i would hate to have to transfer media to a different PC to get what i want on there.
any ideas
From the charging notification, make sure it is in external storage mode to allow the USB PnP to recognize the device for file storage.

I plug the nexus 7 into the PC via USB. N7 says Connected as Media device. but nothing shows on PC
I dont have my N7 yet, but looking at my Thunderbold ... There should be an option for Disk Drive when you open the notification that appears when plugged in by USB. When the Disk Drive option is enabled, the PC will detect the drive and treat it as an external data source.
Perhaps someone who has an N7 in hand can chime in.

yeah no thats not the case here all my other Android devices work fine including my Gnex running JB 4.1 still connects the same way. its just the N7 that wont show up. i can ADB to the N7 but nothing else.
This is my first Sony phone and so far so good, but I can't figure out how to safely eject it when I want to disconnect it from the usb on my PC. Am I missing something obvious here?
Thanks for an explanation or fix for this in advance.
Just eject it. I ejected over thousand times.

If the device is set to MTP mode, it can simply be unplugged because all file system accesses are abstracted. Mass storage mode (MSC) is basically block level access, so data loss may occur if the host isn't properly disconnected and thus the file system dismounted before the device is unplugged. Most people using Windows are probably also using MTP mode, so there's not much that could go wrong. That's the same way most digital cameras or MP3 players work for example.
