Hey everyone first time poster here. I have been researching the question I have in the forums and have not found an answer to my question yet so I figured I would just ask it. I just recently bought my htc evo and tried transferring a SNES rom over to my evo from my PC. At first my computer would not recognize that I was trying to have my evo seen as a disk drive (yes I did have it set to disk drive and not to charge only or another option). eventually it worked (I dont even know what I did, if I did anything at all). After I put this ROM onto my phone my sd card is mounted as read only (cant get it back to write), and no matter what I do I cant get my computer to read my phone as a disk drive. I tried changing the disk drive to another letter which didnt work, under device manager my computer recognizes I have an android phone plugged into my computer, but it still will not show anything in the "my computer" folder, it sees I have a device in, but I click on it and it says "please insert a disk into removable disk F". If anyone can help with this I would greatly appreciate it and thank you for taking the time to read all of this.
Well the first thing to make sure of is that after plugging in the device you go to the notification bar and press on the USB Mass Storage notification, then select "Turn on USB storage". If you've done that simple step and it still doesn't see the SD card, then very simply try a different USB port on your computer.
Even if your card is in read only mode, you should still be able to read it
I don't know why it would be in read only unless you forgot to mount it with read/write after an advanced command.
interesting, I have never seen the option of "turn on mass USB storage" when I've gone to the notification bar? In my notification bar I have a picture of the sd card with a question mark over it. When I drop down the notification bar the notification pertaining to the sd card says "mounted readonly" and the explaination says "The SD card has an unexpected problem. Tapping...." I have no idea what it says after that as it wont allow me to view the rest of the explanation.
As for the problem that this is causing is that it seems I cannot save anything to the sd card. The camera stops working to where I cant take pictures, or download music, and I'm assuming that its because these functions need somewhere to save the files and since the card is on read only nothing will be allowed to save on it?

theres probably an error on the sd card, may need to reformat if its from a different phone too. Try to reformat, probably the only thing possible right now. But before you do that, go to your settings and enable usb debugging and see if that works first to allow your sd card to mount to the pc. Then it should be read as a drive. if not, your gonna have to reformat. so try this, if not, I can try to trouble shoot you more......
thanks for your reply. And yes I shouldve said before that I tried the USB debugging feature as well and that didn't do the job either. I saw reformatting as a suggestion in another thread but didnt see information on how to do it and that is out of my realm of knowledge. If you could explain to me how to do it I would greatly appreciate it.

yea, no problem man, just go to settings>sdcard/sd>unmount the volume>reformat!
let me know if that works for you if not, something else is wrong.
well I go into settings> SD phone & storage> Unmount SD card, is something supposed to happen or am I supposed to do something else? After I tap that nothing happens and the "format SD card" option isnt highlighted meaning its not even an option to choose.
Hmmm. Unmount then remount then umonint again turn the phone off and on see if the uloption highligjts

oh wow that worked man!! Thank you so much for your help, you just saved me a bunch of frustration, now it shows up as a disk drive on my computer and the sd card is read/write compatible. Can't thank you enough man, do you happen to know of a reason as to why this would happen? I mustve set it to be like that somehow I just can't imagine how I did that. Also is there an app or way to back up all your files and apps on your phone and sd card and transfer them to your computer just in case something like this happens again at least I'll have backups so I wont loose everything.
Glad i could hel you. Ita no problem that you cant thank me enough, just as long as we solvee tue prob. You Could have dropped your phone and it knocked the SD card around or it just didn't read it correctly on boot. As far as I know, I don't know of any apps to backup SD card contents and phone data. I would just make a nandroid backup and store on PC. So if you make any vital errors, u can restore using your recovery agent.

I have a problm with my Evo as that it literally thinks its connected to a PC when it's not.
I had the phone, checked for a Astro Fime Manager for a file I placed on SD Card. When I was checking, most things appeared but when I checked other folders, like the Download folded, nothing showed in there. But I know I had files in that the folder.
I then connected the phone to my PC and without it asking me if I wanted to charge it, sync it, use it for disk drive or internet connection, it went straight to the "Use it as a disk drive" feature. Verified because soon as I plugged it into my computer, the SD Card opened on my PC.
I then clicked to have the phone just "Charging" and now I can see everything on my SD card again.
Do anyone know what this problem could be or how to fix it? I thought it was one of the SD Card Problems that was occurring to some phones. But according to this thread: http://forum.xda-developers.com/showthread.php?t=695243
Their SD card stopped working altogether before doing the fix.
Another question about this, will "Debugging" cause this if left on? I had it one for doing the adb stuff when I rooted etc.
Turn off the auto USB switch in the settings of Double Twist.

Thank you so much!!!!! I've been wondering why it was doing this. I was about to go buy a new SD card.
Thanks again!
I had this same problem a while back. I wonder why they thought this was a useful feature. They could have just changed the default option for when you plug in the USB.
So as far as I know, last night before I went to bed, my SD card and phone was working fine, but this morning I went to play some music off my phone, and it said "Please insert SD card". I have one in, and if I go to SD card & Phone storage, it shows it being there, and the correct storage amounts.
I've looked here, done what was said:
http://forum.xda-developers.com/showthread.php?t=695243
I've reformatted my SD card via my phone, and rebooted. It still isn't working. Other apps that require the SD cards use (camera, etc) ask for a SD card as well (although camera doesn't give the msg saying there isn't one, and lets me 'take' pictures, but they don't show up on the card).
I can drop down the notification bar and choose to use as disk drive and it mounts to my computer fine, unmounting and still nothing.
I'm not sure what to try next, any suggestions?
I'm fully rooted running Herver's Baked Snack v.7, let me know if you need to know anything else
Edit: it seems to be fixed, but I haven't done anything to it, so I don't know why or how it is... although if you know of any reason why this happened or have a suggestion to fix it in the future I'd be happy to hear it. Or, if a mod wishes, this can be deleted. *shrug*
Ok, so I have the stock SD card and lately it's been acting up. I went from Vaelpak to CM7RC2 and it took me a while to get the phone to actually recognize the card... Anytime I use a Sense ROM I never have problems with the card being read/recognized by the phone or my PC
So I'm back on RC2 and the phone reads the card just fine but the computer doesnt recognize it "kinda"..
When I plug the phone in via USB to the PC it usually pops up with a window with several options on how to view the contents of the SD card... No such window pops up and the SD card doesnt register in the Drive slot.. it just doesnt show up at all, like there's nothing in that Drive...
But, I can pull up Windows Media Player and look at some of the files on the SD card... So I'm confused, the computer can see some of the information but I can't read the whole thing...
I've tried USB debuggin on/off, mounting as disk drive and not, mounting/unmounting SD card, etc...
Any ideas? -- should I just get a new card or is there something else I can try?
You can copy the contents to the pc, then reformat it, then copy back...

Deleting the LOST_DIR folder has been known to solve the problem with CM7 and SD cards. Having said that, you need to be aware of the recent growing numbers of people boinking their EVOs. All of them were using CM7 and everything had been working as it should. All of a sudden, their device rebooted and have not been able to get into theory homescreen or into recovery. Read the posts the last few days and you will find many instances. I'm just alerting you to what has been happening. That's all so be careful.

I dont guess I explained myself very good... I can't copy anything to the PC if the PC wont recognize that there's a card there.. The PC just sits there and I've looked all over the place but the PC doesnt think there's anything put into the drive

I hadn't seen anything about the "boinking"... can you direct me to a thread? The CM7 RC2 thread or what?.. Not even knowing about those instances I was already thinkin about abandoning CM for now.. I've tried CM6 and several versions of CM7 but there's always something that just doesnt work right.. GPS, the SD card, facebook syncing, etc.. Looking at your Sig I'm thinkin I might try Warm again, it's been a while but I liked it alot... Thanks for the heads up

Yeah, that sucks... I was already about to give up on CM7 for now and that's just enough to push me back to Sense.. thanks
WOW! I'm glad I went back to Sense when I did.
Bricking my phone would end me!
I cannot access files on the SD card. Says the card is read-only. Root access says it's read only. This is through Root Explorer.
When hooked to the computer, computer does not recognize it. Nothing happens.
I tried to unmount then mount through the phone settings but nothing happens. I noticed that in the settings, under "SD and phone storage" the Available Space says "23.15GB (Read-only)."
Everything was working fine up til today.
I don't think I hit anything by accident. What can I do to access the files?
In root explorer up at the top there is a little box that has RO/RW on it, did you hit that by mistake?
edit...re-read post, PC doesnt recognize either? Do you have a adapter, remove card from phone and use adapter to put into PC. Card could be toasted
ON Windows7 it asks to repair cards when mounting them, that may help too.
don't know if you tried this already, it might help: when you go to root explorer on top of the screen you should see r/o or something like that tap it and it should change to r/w that will give you read and write right.
didnt see cordell12 answer, beat me to it +1
What is the specific card in question?
i think its a 32 gig cause he said 22 free but if the button doesnt work take out the card and try it again but the button is a dray bubble at the top
I'm having the same thing going on with my stock evo card. Don't believe I did anything by accident either, just randomly happened
Need a way to access internal memory so I can fix my usb or sd card see following for information:
Short Version:
USB wont work and SD card wont work so I cannot use the following method http://forum.xda-developers.com/showthread.php?t=695243
Long Version:
So right after i had backed up my rom i did a wipe, then the phone stopped recognizing my sd card. I took it to Sprint they couldn't figure it out, so i was stuck in Bootloader. yesterday i did a hard reset and wa-la i can now use my phone ...sorta. It will turn on I can access everything, but it freezes up and shuts off after 40 seconds (i got it to stay for 2mins one time) also it still will not recognize my sd card. I tried other cards still no luck and I know my card works because I can use it in my laptop. So i did a little searching on xda and found a fix, but i cant do the fix unless i plug my phone into the laptop and run a cmd prompt well now here is the other problem my computer sees the phone (listed as My HTC) but my phone wont recognize that it is plugged in. It will charge when it is shut off thats about it. Well back to xda and there is a fix for the usb, but.... I need my phone to recognize my sd card because the files will be on it. In short to fix my sd card i need usb and to fix the usb i need my card I am stuck in a horrible loop, so what I need is a way to access my phones internal memory so I can install the usb files on it so that i can fix usb then my card, then recover my rom.
Thanks to wall who help or at least try
Im not totally sure if this will help, but i know you can mount the sd card as usb storage in Amon_Ra and also in settings under "storage" or so i believe there are settings for mounting and unmounting the Micro Sdcard check those, it should be mounted in the settings for your phone to see it. hope i helped
I just had this exact same problem. Nandroid, wipe, flash, then stuck in bootloader spent two days trying fixes, unroot, root, and,had to turn it in. Luckily best buy has an awesome warranty.

thanks all... ended up replacing my phone, but if anyone ever finds a way to fix it let me know! Thanks again
I was really hoping that this thread would not dead-end. I've got what sounds like a similar issue...in addition to not being able to reformat my SD card (in Windows or in Android) due to it being detected as write-protected, but it's not write protected.
I'm really anxious to try the aforementioned thread to fix USB and SD, but I can't detect, mount, or format my SD card. Am I screwed?
*EDIT* Fixed the write-protection issue...working on the rest now.
*EDIT* Still can't format card through Android. Is there an ADB or fastboot command to format the SD card?
