Can't mount USB

It's the second time this has happened. I'm not sure what I did the first time to fix it.
Basically, when I try to mount my SD card via USB it tries to - but then fails and goes back to "preparing SD card" on the phone. It never shows up on the PC.
I'm running Gumbo 1.5C with kernel.
I tried going back to my RUU image/formated SD and start over but the problem still persists. The card is partitioned for Apps2SD. If I need to format the card can someone provide instruction to either move whatever is installed on the SD card back to the phone or how to back up the SD card so I wont have to clean everything up again.
Would be very much appreciated!
Thanks!

I am always the person who asks the stupid "is it plugged in?" questions...
Did you try using the SD card in a different device?
Does the phone let you store on it?
Can you install new Apps?

No, I don't really have another device to try it in... but it does work. The card does mount through the Recovery USB toggle. It just doesn't mount through the OS.

Yes and yes.

I can try another one when I get home but the problem is I wont have any of the apps that were installed on the SD card.
What I did just try is "unmount" the SD card on the phone so it looks like I'm about to remove it - then restart. It's still not working. I kind of want to say that the problem arose when I pulled my phone off the USB cable while the card was already mounted - to answer an important phone call. I'm just not sure how to replicate or undo the problem.

This will kill it every time.
The best thing to do is go into recovery make a back up of the EXT partition - theres an option for it some where. Mount the card in recovery copy the backup to the desktop. Power the phone off swap the SD card. Partition it with the EXT partion. Mount the new card as USB in recovery copy the back up to it (make sure you keep the original folder path exactly the same). Restore the EXT back up. *catches breath*
Maybe this will work for you. I had a very simliar issue destroy my 16gb. It was sadening those things aren't cheap.

I may give this a shot later, I just want to wait to see if anyone else has a solution. The reason being; this has happened to me before. About 2 months ago. I think I fixed it by changing to a different ROM... which is not what I want to do now. I like the speed I had now. There must be some haywire code that gets corrupted if I dismount improperly considering the SD card is still fully functional.

And... Bump.

How about... did you try a different usb plug, different usb port, different computer?

[Q] Removing SD while Android is running - what happens?

Hi there,
Since there is a unmount sd card in the settings of android i tried and unmounted it and took the sd card out to put some files onto it.
Well then Android was running for some more seconds, but then got stuck.
I suppose removing the SD card was not the best idea i had. (Even though i thought all the android files after booting were in the internal memorý)
Can someone explain to me what happens when i remove my sd card while android is running?
Is it damaging the file system?
Is it damaging the card?
Is it damaging the phone?
Sorry..have no clue at all
So thought i ask before causing severe damage...
Cheerio

Thats exactly what I have done a few times (I forget that I have to boot into WinMo first).
I don't think it'll cause any lasting damage... At worst, you'll have to start a fresh ROM - But i've not had to yet !

It's certainly not a good thing to do. You are more likely to have file corruption, which of course can be fixed with a reinstall (you might even be able to keep your data.img).
It's also not good for the SD card. Removing it without really unmounting (we can't really unmount on HD2 without nand), increases chances of having your sd card bricked. Odds aren't big, but still not recomended. Your phone doesn't suffer any damage at all though!

ok thanks! Reinstalling the build right now...how would i realize if my card is bricked? not working anymore? loss of speed?
Thanks!

crash... i tried it before.. wasnt funny...

Could be all kinds of problems I guess, but Android would probably just crash after a while and not be able to reboot. Chances are low though, you usually needn't worry.

[Q] Help - Phone can't see sd card

I'd really appreciate some advice.
I have previously rooted my mini HD and tried a few roms but I had a boot problem the other day after a flat battery and I ended up having to restore Windows 6.5 to get the phone to work.
The problem I've got is that although the phone seems to work OK with Windows it will not see any SD card that I put in it...so I'm a bit stuck because I want to install an Android rom again, and without access to the SD card it's impossible?
So, any ideas how I can get the phone to see the SD card?
I have already reformatted the SD card using gparted to FAT32, and it's the same card that was in the phone before. I've also tried a different card but the phone refuses to see it.
Do you think something in the bootloader is messed up...I can't think that this could be a hardware error.
Any ideas would be great!
cheers.

maybe try another SDCards?

Thanks for your reply iPlasm,
I've tried 3 different SD cards, all working ones, and the result is the same...when I look in settings on WM it tells me "no SD card" and if I try to format SD card using "tools" it also tells me "no SD card present".
Something is obviously wrong with the WM system - I've tried different stock WM roms using RUU's and I get the same result....everything was working fine before my flat battery issue but being unable to recognise an SD card is a big issue for me to get around so that I can root the phone again and install an Android rom.
Is it possible to run Haret from the main device and install a custom recovery? I'd have to email myself the necessary files and cut and paste them using the file explorer on WM unless there is a different way...or is this just barking mad?
Any ideas to resolve my problem would be much appreciated.
Cheers.
Ade

Well.. I don't know what to say.. you were talking about battery, so how about try the old ones?
I don't have really much ideas about that, but i think it should be easy fixing or can be dirty inside the Hardware's SDCard input, you may have to clean it.

Tried all of that - still won't see card. This must be a software issue that is beyond my reach.
How can I root this if I can't use the sd card?

[Q] Is my SD card slot fried? Please help!!

Hi Guys,
I'm on Temasek's CM11, been using this Sony 64GB microSD card for over a year, and today, randomly while the phone was in use, I saw a message pop up, SD card unexpectedly unmounted. After that, it's not using up in the file systems, all the way down to the Recovery. I'm using TWRP.
I put the SD card in another Note 3 I have and everything seems to be fine on there, all the data is here.
So just posting here to make sure that is it safe to conclude that my SD card slot is fried?
And if so... What are my options... I have had the Note 3 for over a year and brought it off of Craigslist. It's unlocked and use it on AT&T...
So any ideas or advice friends? And yes, I pressed the SD card firmly in my Note 3 many times...
Thank you!

Unless you smell ozone or see burn marks it is not fried.

Hi Gary,
Thanks for your response! Definitely no smell, no burns. But, SD card is not visible even in TWRP recovery, but works great in another Note 3 I have.
Can you, or anyone else recommend what I can try before I conclude it's a hardware issue?
Would appreciate any help guys!
Thank you!

It is probably your ROM. If it is working on another phone, then nothing wrong with card. Hardly doubt it's hardware, but never know.
How about trying another card in your phone and see if have same issues.

Have you tried another SD card?

Yes guys, tried another sd card, same result, but the card reads fine in the other phone. Even the second card. Remember, the sd cards are not showing in Recovery either... that sounds like a (hardware) problem ...?

No idea. Have you tried saving all your files from SD card (to computer), then format that sd card ...see if it helps.
If not, then it could well be hardware. If you can find a phone repair shop (not official samsung one), then they can probably replace it.
I don't think any official Samsung one will do it for you (since phone is modified), but can try lol.
Good luck!

Note 4 detect SD card but can't read it!

I have a very specific problem that I have been trying to solve.
I have a Galaxy Note 4.
For the past few days, my phone has not been able to read the SD card and is stuck on "Preparing SD Card"
Here are the facts I have come up with:
- My phone will not read any SD card and will continuously stay at "Preparing SD card" no matter how long any card is in the phone
- The current SD card can be read in others phones and my computer.
This leads me to believe the SD card is not corrupted and that the files may still be able to be accessed. The other info I have found from forums tells me the best way to get the phone to read an SD card again is to reset it, but I don't want to do that.
Try to use app name [ SD insight ] from the market, it can read the manufacturing of SD and all the information! But still cant browsing the file.
I would be so appreciative of any suggestions.
Thank you for any help you can provide!

I'd take your device to a Samsung Service Center as there is a chance that your device's microSDCard reader is faulty and needs to be repaired.

Thank you for replay, actually I take it to one phone workshop and tell me same as you say, but still I an confused if can get all information from th SD card why I cant brows, and afraid I did some thing wrong after root my phone and its the reason for this.

which brand is your SD card? try formatting it using pc and try again. sometimes memory cards get write protected after sometimes. you can read from it but can't write or delete from it anymore. I had a transcend SD card with this problem

Actually rooting your device should cause such a problem. Unless you delete the drivers for the microSDCard reader on your device. I'd recommend reinstalling the stock firmware onto your device to see if that will fix your problem. But don't root it this time around.

I didn't delet any driver, just install some app with some editing in there files. You're right, I will reinstall stock firmware before take the phone to workshop. Thanks again

Thank you foe reply, its not famous brand (kingmax) but work perfectly in computer and other phone, also try another SD card and not work in the phone. I will reinstall stock firmware to make sure the problem from hardware not software especially because I root my phone and get some errors like screen not rotating and hotspots not working.

If you are getting those errors then there is a possibility that the rooting process messed up the OS and the device drivers on your device. Reinstalling the stock firmware back onto it should solve your problems.

Done, thank you.
After re-install the stock firmare every thing return to work fine, SD card and also flash USB. it seem that driver to read external storage was delete by BusyBox or anther root app.
Any way I didn't lost any of my app or data, thank all of you guys.
