Most all my searches returned something about rooting, how to mount via console, etc, so I started a new thread. If someone knows of one off hand, please LINK to the thread in your post. I'll ask a mod to lock or delete this one IF and WHEN a good answer is found... thanks
I'm using froyo, and up until yesterday mounting the sdcard via my mac's usb connection was painless. Gallery works fine while not connected, and copying files between the mac and the nexus is flawless also.
the problem comes when it's time to use the sdcard again on the mac. 'disable mass storage' dialogue just hangs, and after 30 seconds or so i just pull the battery. i've tried:
umounting fomr the mac first, then quitting usb mass storage on the nexus
and
quitting mass storage on the nexus THEN umounting on the mac
doesn't seem to matter, it just makes the nexus hang, and a battery pull is required to make it usable again.
any tips ?
also, if this is a common problem, or a bug, please let me know and i'll ask for a thread close/lock/whatever.
use a new kernel, from either wildmonks, intersectraven, or pershoot (in the persianown thread)
I just looked at the three kernels mentioned above and they are all UV/OC kernels. (Maybe I missed something) Is there one that is on .34 that not but has the USB mount/unmount problem fixed?
I've had this exact same problem before, unmounting would always freeze. But I also would experience a hang when copying over a very large file from my computer to the phone via USB. Turns out in my situation the SD card had gone bad (it produced some other weird behaviors when not used with the phone), and using a different card immediately solved my problems.
Not sure if this is the same in your case, but it wouldn't hurt to try a different card and see if you experience the same issue.

Hit up wildmonks, and see if he can make you one. Even with OC, it won't OC unless you set it too. Otherwise it's at 998mhz.
I have been running CM7.1 RC1 off of my SD card without for about three weeks now.
But today, my NC started freezing often. Sometimes it won't even finish loading the home screen. Additionally, when I make any changes (wallpaper, ADW settings, install apps), the changes/apps are not there after I reboot.
If there are any gurus out there who can help me out, I'd really appreciate it.
Well I would say your sd-card is getting a bit overwhelmed with all the stuff on it what size brand and class is it?
I have a Class 4 16GB Sandisk uSD.
Under storage settings:
SD is listed as Total Space: 13.31 GB, Free Space: 2.13 GB
Internal Storage Total: .93 GB, Available: 574 MB
Additional storage on /mnt/emmc Total: 1.00 GB, Free: 1.00 GB
I also tried deleting 4.55 GB in files is ES File Explorer. But when I restarted, they came back.
To recap: Freezing often; files I delete come back after restart and files I install disappear after restart.
I was getting problems like that after any force close happened -- any settings changes I made would just vanish after rebooting. I had reinstalled CM7 a couple of times and that always seemed to fix it, but something always would creep back again. I finally just installed CM7 to emmc and haven't had a problem since.

I was thinking about that, but since I've been having issues with the screen while plugged in, I wanted to ensure that I don't void the warranty on my NC in case I have to exchange it.
Edit: I also like having the multimedia storybooks to read with the kids.
I've seen enough anecdotes about SD installs suddenly going bad that I wonder if they're stable in the long run, but not enough to convince me that they're not. My SD install did go bad (more conventionally: force closes and lag), but I was already thinking about moving to eMMC, so I just took the plunge. If anything, I might set up a stock 1.2 SD card down the road.

While it wouldn't help with dual-booting, you could also keep a microSD card around to revert it to stock if needed. I thought the latest nook app was supposed to support storybooks, but it gave me an "unsupported" error when trying to open an "enhanced" book, so I don't have much personal experience.

Yeah, it seems like this is an unspoken problem here. I'm not sure how prevalent it is, but when you do mention weird behavior when using an SD card, usually someone will suggest moving to emmc or say they had a similar issue when they were using an SD card as well.
Well, I went ahead and put Phiremod 6.3 on Emmc. No issues yet...
I had to buy a new SD card. The one I had CM7 on was completely locked up. I couldn't delete, save or even format it.
Thanks to everyone for the advice!
Use MiniTool Wizard or EASUS (or whatever) to format the uSD card
I would love anybodies help
So heres my problem.... over the many different roms i've used Mass storage has been an issue.
USB mass storage mounts to Windows and i begin a file transfer to the SD card. It'll start out around 1MB/s and slowly crawl down to about 100KB/s then sort of halts. Canceling never finishes....
This led me to believe it was the SD card class holding me back, but waayy back on eclair and froyo, this was not an issue.
I am currently running CM9 beta 1.
I booted into Clockwork Mod Recovery v5.5.0.4, mounted the SD card in Windows and started transferring a couple GB's of videos to the SD. Sure enough, the data transfer rate started out around 8MB/s and stabilized at 4MB/s until the transfer was complete.
Anyone have any ideas what could be holding me back?
is there some kind of cache i need to clear on the SD?
Btw, clearing out random files and such didnt really help, and formatting the SD only made the least bit of difference. Using a very short high quality USB cable i got for flashing from monoprice.com
Ive had this issue on CM9 CM7 CleanGB and many others..
does anybody have any idea about this?.... a solution??
Thanks a lot
This is my first phone that uses MTP. My last phone had an SD Card, and used USB Mass Storage, so I'm not sure if this is normal behavior for MTP.
I plug the phone in, and the only way the computer recognizes it as a storage device is to have USB Debugging off, and the phone set to "Connected as a Media Device (MTP)". If I set it to connect as a camera, it only sees the DCIM and pictures folder, and it only works if USB Debugging is turned ON. So that's the first weird thing.
All I really have installed driver-wise is the stock android drivers that are included in the SDK, installed using the device manager method. I am rooted stock, running Franco.Kernel.
I am connecting to the computer using the cable that came with the phone, although I have tried 4 other cables and they all return the same result.
What happens is, I plug in the phone, and it pops up in My Computer as "Nexus 4, Portable Media Player". So I click on that, then click on Internal Storage, the only available option. It takes about 5 seconds to load up all the files.
I am trying to back up all the files on my External Storage before I flash a ROM. I know it's not necessary, but better safe then sorry. So I highlight all the files, and drag them into a directory on my computer. And a dialogue pops up that says "Estimating time required to transfer files" or something like that. And it just sits there. I let it sit for about 15 minutes, and after it did nothing for that time, I hit cancel. To get it to fully cancel, however, I had to disconnect the phone and reconnect it.
So now I'm trying to do everything 1 by 1. Transfer 1 folder at a time. The smaller folders work fine, although they're still incredibly slow. Over a minute for a folder with 2 Megabytes of data in it? That can't be right. But then I hit the bigger folders, such as the "Android Folder" where all the big games are stored. So I drag that folder into the directory on my computer, and it spends about 25-30 minutes "Estimating time required to transfer files". Then it starts the transfer. It says it will be about 2-3 hours. There's around 3 GB of data in the folder, according to right clicking on it and clicking properties, so I guess that's a semi-reasonable amount of time, but still pretty slow compared to my old phone. But then, after about 20 minutes of copying data, it just stops. It looks like it has finished, but upon going through the directory on my computer, and comparing it to the one on the phone, it has only transferred about half of the files. So I try again, repeating the above process. And the same exact thing happens. It always stops at ~1 GB out of the 2.7 it should be copying over.
What gives? This is literally the most frustrating thing ever right now. I just want to flash PA so badly but I can't get my stuff to copy over!
Please help! Thanks so much!
The good news, that's normal.
The bad news, that's normal.
Try pulling your sdcard via ADB, it's more reliable.

That's so bad if that's normal. Why Google switched to MTP is beyond me. Another weird issue is sometimes it can take forever for the filesystem to update on my computer. I can put an apk file that I downloaded to my phone on the root of the external storage. Then, when I plug it in to my computer to transfer it off, it won't be there. I reboot, it still isn't there. After searching and searching, I went back, unplugged the phone, plugged it back in for the 20th time, and it randomly shows up. So frustrating.
Anyway... what's the command for adb pulling that? I know the external storage is called something like /emulated/0 or something. So would it be adb pull /emulated/0 C:\Users\blahblahblah?
Mines doesn't take 5 seconds to load up. Very speedy for me on transferring files back to back. On Windows 7 SP1.
We didn't do this because we wanted to use ext3 (although that is a side benefit.) We did it because we wanted to be able to merge the "public shared storage" (i.e. for music and photos) with the internal private app storage.
We got tired of seeing OEMs include many GB of internal storage for music, while users were still running out of space for apps and data. This approach lets us merge everything on one volume, which is way better.

is the reason why they used MTP. I personally prefer MTP even though some people always encounter problems with it and I have none. It's very handy on devices with a SDCard as well as Internal Storage, rather than having two of them pop up on "My Computer" it is merged into one and you can select which one you want to go into. Sometimes people are confused which one is which. Not to mention if you have an app that relies on data on the "sdcard" (internal storage) and it is currently plugged into the computer. It won't be able to read that data because it is in USB mass storage mode.
Certainly your situation is not normal.

That is not the reason. The reason is Google is slyly forcing us into a thin client platform ala chrome book and nexus. If Google doesn't start releasing nexus with at the very minimum larger storage, I.e. minimum 32gb on nexus, (would rather have SD slot) they will probably lose me as a client altogether. Yes I will probably still use Google maps at the very minimum but everything else I am in no way attached. The cloud is a poor replacement for local storage, and yes I too think off site storage will be a major factor in the future but give us larger storage options during this transitional phase. The cloud is slow, data is expensive, data is not widely available like oxygen is, I don't want to stream music, much less have any possibility of commercials and ads during my musical nirvana and transcoding my FLACs/wav's into 320 kbps mp3 is just piss poor bull**** and a very good reason why people should NOT willingly sign up for cloud services. Handing over ownership of your data and getting a lesser quality experience in return is just asinine and stupid. And Google drive is a poor excuse of cloud management and how come Google isn't forcing more developers to implement Drive and/or cloud services into android ecosystem, much less Google themselves just screams how bad Google wants to shove an apple up your anus.
I voided my warranty.
Let's not turn this into an argument over why mtp sucks. I'd just really like to know how to fix my problem.

that's all conspiracy about taking off MTP or SDCARDS in favor of their cloud service but i do agree with you, the 8GB/16GB combo was kind of silly, they should of done 16GB/32GB to the very least, as a person who lives in NYC and takes the subway. I won't always have service because underground we don't get any (we're starting too.. but it depends on which stations you're at) so the cloud isn't a viable option for me and it shouldn't be for most people anyway because of the data caps that carriers impose on them.
16GB is enough for me, but still would of been nice for a 32GB version. I hoped google learned from 8GB/16GB format for the N7 but guess not. should of been 16GB/32GB for N4 and I'd be pretty upset if they discontinued 8GB in favor for a 16GB/32GB as i paid for a 32GB at ~$349.
of course, google isnt telling everybody to get a nexus device. there are other alternatives out there such as galaxy s, note, etc. I personally like nexus devices for community support when it comes to custom roms and kernels.
Let's PM the devs start asking for Mass Storage support?
I hate MTP. I really really hate it. WiFi solutions (AirDroid, Samba, Total Commando) are not ideal either. I don't have to list the disadvantages, do I?
OK people, let's start a different thread so we can voice why mtp sucks. For now, can someone just tell me if what I'm experiencing is normal, and if there is a way to fix it? Or what the adb command is to pull my external storage onto my computer is? Thanks!

adb pull /sdcard/ *should* work, although I haven't done it on the N4 yet so can't confirm if the /0/ throws a wrench in the works. It will still likely be painfully slow, but it won't just stop altogether for no reason.
I'm also a big fan of adb backup/restore, saves a lot of trouble when restoring your junk, including the sdcard. To back up your apps and the sdcard it would be:
Code:
adb backup -all -nosystem -shared -apk
Code:
adb restore backup.ab
A restore of this is all, or nothing, it will restore your apps, some settings, and the sdcard after you've flashed.
I think I'm going to just backup my pictures and TI Backup files. That's all I really care about anyway. I don't have time to wait 4+ hours just to copy a few GB's off my phone.

It's emulated because in Android 4.2.X it supports multi user on tablets.
It has USB Mass Storage for other phones because that's the way the manufacturer developed the device. It supports USB Mass Storage. Phones/tablets by Google use MTP.
Google for the topic of discussion on Galaxy Nexus, I don't have the time to find it on Google. But I'm sure with some searching with google somewhere between the lines "USB mass storage on galaxy nexus possible?" would lead you into the right direction. Best thing I can say is to just believe me because if it was possible, I'm sure that it would of been done on the Galaxy Nexus already which is a one-year old device.

A good alternative to MTP is to just use your phone as a FTP server and move files around that way. That's what I do instead of dragging and dropping files via USB cable, I don't have any problems with MTP but I do have a problem with beating laziness

I'm copying over using adb pull /sdcard/ which seems to be working, although it keeps getting stuck on one file. I've deleted the file and I'm trying again though. It seems to be going a lot faster than straight copy and paste though.

New to XDA, not new to Android.
Phone: Moto X Play
Rom: Stock Marshmallow 6.1
Issue: SD Card disappears randomly (formatted as internal storage!!!)
Bootloader never unlocked, never rooted.
I have a sandisk 32gb micro sd card that works when I first start the phone. The problem is that it will randomly, completely, disappear.
Now I'm not, IMO, a complete noob. I am fairly (99%) sure it is indeed the sd card at fault. Ok, not an issue, I can always replace it with a new one.
The issue is, of course, that EVERYTHING is on my SD card, most importantly, my photos.
Even without accessing a file manager (phone idle, browsing web, playing games) the sd card will eventually fail leaving it inaccessible until the phone is restarted. When attempting to access my photos, which is what I need most, it fails MUCH quicker.
Having not used the "Google Photos" app before (just Gallery), I am not at all sure if my photos were ever backed up online, If they were, I'm not sure where to look.
Trying to access them via usb, wifi file transfer, bt tranfer, and even from file managers on the phone itself, result in an almost immediate failure of the sd card. 5 seconds or so tops.
The card is formatted as "Internal Storage" and I have not been able to find a way to get a computer or anything else to read it, and I would imagine for security reasons, there is no way.
Here's the question: Is there any way to get photos off the sd card, that wont take me three million years in 5 second intervals, while having to restart the phone every bleeping time the sd card fails to get it to recognize the sd card again?
Suggestions please!
Thanks in advance,

Format the card using computer (Not quick format )
Quick format didn't worked for me.
And don't make card as internal, use it as portable
with the sd card in the phone, go to settings - apps, show system apps. then select External Storage, force stop it or clear it cache. do the same to Media Storage. reboot the phone, once everything loaded wait for 5-10 minutes especially if you have lots of files in a large sd card. once that done, connect the phone to your pc (use mtp if i'm not mistaken) and hopefully you can now access the internal (sd card) contents.

One question... If the card is formatted as internal storage, clearing data for external storage and media storage will not cause the phone to "forget" the sd card will it?

I think I have come up with a solution to my own problem. If this works satisfactorily, I will let others know as this may help many other people facing this issue.
I am on a linux pc. I am going to try to use RSYNC to copy the files over. This SHOULD copy files over, deleting them from the source folder as it goes. Once the sd card fails, which it WILL, once I reboot the phone and start rsync once again, it should "resume" where it left off.
Here is the command for anyone else that may need it:
rsync -v --progress --remove-source-files --recursive --append-verify /path/to/source/files /path/to/destination/folder
Hopefully this works the way I hope it will. Will post back with my results when I can.
Thanks again,
Canabian.
I had the same problem, and the solution (that maybe someone posted somewhere in the internet) is using a faster SD card. Since I switched to a sandisk extreme pro, the problem disappeared. Be careful, though, when using Samsung SD cards: my moto x play doesn't like them much (I had to replace them twice before buying the sandisk; in some way the partition tables of the Samsung SD cards were damaged, plus they became read-only, resulting in two unusable cards).

which samsung model did you use? I just replaced my normal class 10 strontium card yesterday with a brand new samsung evo plus u1 card and formatted it as internal storage. so far the phone feels a bit snappy with this card.
dude search a little in this section and i hope u find the fix.i just let u know that our device has very sensitive sd pins and many users had accidentally bented them and didn't know the problem!
i hope u are not one of them!so if you are lucky,next time u put the sd be veeeery careful!i personally didn't put it out from the time i bought it...

It was just a Samsung Evo class 10. The strange thing is that I tried also a Sandisk of the same class, which gave me only the "external memory missing" problem, while the Samsung ones became just unusable plastic. But maybe I should try better Samsung SD cards.
