Can't get my Evo to mount disk anymore.

I have rooted several times in the past. I believe I know what I am doing. Now that I have this ROM installed, when I plug my Evo into the usb, it does not even prompt me for connection type, such as internet sharing, mount disk etc. I try toggling usb debugging, still no go. What should I do? As of now I can not access my SD card because USB does not work, even tho the LED comes on as if it is charging.

This might help

I did the SD card thing. Didn't change anything. Can't do Fix USB because I can't access my SD card.

What rom are you using? Was it working previously? I'd try a restore from the last time you knew it was working.
Edit: can your computer read the Sd card if you put in a reader?

how would I do a restore? Also, I don't have a microSD card reader but I guess I will get one.

Any more ideas broskis? Sucks not being able to flash more roms. The "Choose a connection" box doesn't even pop up when plugged in via usb.

I got this a couple times today. Dunno what's up. Maybe an apk that was removed? Mine doesn't even want to charge anymore. 0.0 phone will charge for a second then nothing. Only have 40% life left.... ((

EVO disk drive confusion....
Hey guys, really new to the technical aspects of the android scene.... looking for some help....
I have an EVO 4g that WILL NOT mount as disk drive, on either of my 2 WIN 7 computers; it will charge, and the physical connection doesn't appear to be lose or damaged, as it connects to charge without problems. This is rooted w/ unrEVOked 3. Computer doesn't recognize it at all, either debugging off or on, with my default choice being 'mount as disk drive' and 'ask me every time' chosen.
It is not the USB port on the computer nor the cable, because another EVO, although newer, same setup, connected in the same way works just fine....
I have no issues with the phone reading the SD Card app2SD programs that I have on it... I have tried removing the SD card and battery and reseating them with nothing changing.... I rarely connect to the computer..... but I have almost the same set up on both phones as far as programs, ROOT method, etc.....
What should I look for that causes the computer not to recognize this one???
Any and all help would be appreciated, and I would be HAPPY to donate to any of you DEVS that can help me find and fix this!!!!!
THANKS!!!

[Q] HTC Evo Not Connecting to PC Correctly

I've been having troubles trying to get my rooted Evo to connect to my PC. Whenever I plug the device in, the windows XP USB inserted sound plays, then within 2 seconds or so the USB removed sound plays and the sd card is ejected before I have time to access any of the files from the computer. However, if i go into clockworkmod and mount the sd card that way, the files are accessible on my computer. Either way though, my phone wont charge via USB. I tested my USB cable with another phone of mine and it works fine so I know that isn't causing the problem. I've also tried plugging the device into multiple computers with the same result. Has anyone else had this problem? Any help would be greatly appreciated!! Thank you!

[Q] Can't mount USB Storage on my Windows 7 PC

The problem is more about my PC than the Desire as it works as normal on other PCs but not on mine.
When I plug in my Desire it asks me to mount the USB Storage and when I accept the Device shows as "Removable Disk (F" opening it results in "Please insert a Disk into...".
Under Device Manager it shows as "Portable Device" and under "Disk drives".
I uninstalled every device with Android in it and then rebooted my PC and reconnected my phone but still no luck, I also tried installing the newer HTC USB drivers (didn't work) and then uninstalling them (didn't help). It must be because of some driver but I have no clue how to fix it.
Does someone know?
I have the SDK, the unrevoked HBOOT Drivers, the HTC USB Drivers (from the Sync app) and Windows told me all the USB Mass storage drivers got installed and should be working.
//Edit:
When I mount the USB storage, got to the drive in the Device Manager and select populate in the properties and then go to the Disk Management I see the Disk but it's labled as RAW. When I then re-format it, it actually works until I unmount it and then re-mount which presents me again with my previous problem.

If you just want mount the USB storage, you no need to install other software or SDK.
I think that is your pc's problem, try check your pc.

Are you using the original micro usb cable from HTC or a dodgy cable you bought really cheap? There are a lot of bad cables around.
It could also be that your SD card is about to die.

@ First line he say it works as normal on other PCs but not on mine
so maybe not cable problem

To mount the Desire's SD Card in storage mode you don't need any drivers than the ones came with the OS - tested on XP, Vista, Seven and Ubuntu - it's like sticking in an USB pendrive / external HDD.
Did you tried a different USB port?
Also try set USB debugging mode on (Settings\Application\Developement)

Original cable; SD card mounts fine when taken out and used with an external reader; tried other ports; no problems on other PCs; Debugging on or off doesn't help
I know it's my PC but I don't know why and how to fix it. I also know that it installs everything automatically and I don't need to install any other drivers but one that is installed, seems to break everything.

What about USB extensions? Do you use this @ your PC? How many other USB Devices are connected to your PC? Maybe your phone doesnt get enough voltage via USB. I know both problems from my personal experience.
So first, if you use extension cable, remove it and connect your micro USB cable directly to the board.
Second, try to remove 1 or 2 other devices plugged in via USB (scanner, printer, cardreader[!], webcam, for testing purposes even mouse or keyboard)
Maybe this fixes your issues.

No extension cable
I doubt the power being the problem as my Galaxy S II had no issue and as stated above I could kind of get it to work but not as it should have worked.

You DOUBT the power beeing the problem, or you tried and can EXCLUDE this possibility?

Considering what I've already tried (as detailed in previous posts) I think I can exclude the power being the issue.
I've also synced and charged an SGS2, an iPod touch and an iPad from the same plug without any issues.

I tried so many things in the device manager... nothing worked...
Once I could get it to mount correctly but only until I unmounted once, after that it would go right back to my problem.
I really have no clue on how I could get this to work again

I give up... I even restored Windows 7 to a previous state and it did not help.

Made some progress and can reproducably access the SD card but sadly only until I unmount and afterwards I have to run through the procedure again to get access:
I had an USB Harddrive formatted as NTFS through NTFS-3G on my mac and my Windows 7 PC also wanted to format it when I plugged it in and it showed up as RAW in Computer Management. I then remembered chkdsk did a chkdsk I: /f and it worked again even after a clean eject and remount.
I then tried this on my Desire as the symptoms seemed the same or at least related. Here is my console output:
C:\Windows\system32>chkdsk H: /F
The type of the file system is FAT32.
Chkdsk cannot run because the volume is in use by another
process. Chkdsk may run if this volume is dismounted first.
ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID.
Would you like to force a dismount on this volume? (Y/N) y
Volume dismounted. All opened handles to this volume are now invalid.

After this, Windows showed that it mounted DESIRE correctly and asked me what I'd like to do with it and I could browse the card and do whatever I wanted.
But this isn't ideal behaviour and I'd love it if my Desire would just show up as normal and work normally when I connect it to my PC. Does this give a clue on where the problem might be?

Hello
I had a simular problem
I could mount the sd on my desktop but not on my laptop.
So apparently it was not a cable problem...
But finnally I use the original cable and now it mounts on both computer.
Hope this helps

[Q] Mount SD No Longer Works?

It was working fine yesterday, but today in MIUI (same as yesterday), I can tell the phone to mount the SD card but it doesn't show up on my computer. So the phone says it's mounted, but it apparently isn't.
To make sure it wasn't a problem with the ROM, I rebooted into to CWM and mounted there, same thing. CWM says it's mounted but it doesn't show up on my computer.
I can view and edit the files on the SD card through ES File Explorer, but the SD card no longer appears on my computer?
It's not the USB port, I plugged in a flash drive and it worked. And I'm using the stock HTC Cable.
This is on my Inspire.
I'm inclined to say it's the wire, but nothing happened to the wire between today and yesterday. It was just sitting on the floor, and it still charges the device.
I did reboot my computer and phone...still no luck.
Does USB debugging have anything to do with it? I've been rooted for months and I never disabled and it didn't cause problems :/

Out of the two inspires in my household, one of my cables stopped working only a month after I bought it. It still works for charging but does not work for data. Have you tried a different cable just to be sure.

It might not be the phone nor the Rom since you've done some basic trouble shooting. It could possibly be your PC. Have you tried it on another computer? Possible driver problems or drive letter conflict might cause it not to display in Computer.
You can check whether Windows has detected your device by going to Start > Devices and Printers, it will pop up there if it is detected. Otherwise you can also check Disk Management. To do this just right-click on Computer > Manage > Disk Management. If you see the removable disk and sure that it is your SD card then it might be a driver letter conflict which you can easily fix by right-clicking on the removable disk and clicking "Change Driver Letter and Paths" and changing it to an unused driver letter. I've had similar issues with USB drives in the past. Hope this helps!
Cheers

[Q] SD card no longer recognised in windows

I can no longer access my SD card from my windows pc when connected by USB. This occurred on the same day that i unlocked my bootloader, installed the java sdk and android sdk.
I have the phone set MSC (mass storage mode) and connect it by USB as I always did in the past.
Windows recognises that something is connected and a new removable drive is created.
In the past my phone would give me the option to connect the memory card, however this no longer happens.
Clicking on the new drive in Windows causes a message box to pop up saying "Please insert a disk in drive..."
No amount of fiddling with usb settings (debugging, MTP, etc) plugging / unplugging or rebooting has made any difference. I've tried reinstalling USB drivers and removing & reinstalling Sony PC companion. I've also tried accessing the sd card from ubuntu in a virtual machine, but that also doesn't work.
I can view the SD cards contents from my phone and through an adb link.
Does anyone have a solution? From extensive googling, the only things i can see that i haven't tried is:
- trying a different cable (which has been suggested but sounds pretty daft to me)
- reformatting the sd card
Any other suggestions? If i do have to format the sd card, are there any good guides or is there anything i need to avoid doing???

Can you read the card from a card reader.
if you can it is then either drivers or the cable
Sent from my LT15i using xda premium

unfortunately i don't have a card reader. I'll give it a try tonight in my girlfriend's phone and with a usb cable and see how that works out.

it will definitely work with a card reader...this problem occurs when usb storage suddenly stops working as soon as usb is connected..i guess best way is to reinstall ROM if the problem persist.

Flashing firmware (global v62) got it working again )
