[Q] Epic 4g Microsdhc issue and One Click Root & Recovery v2.5.5

Hi,
Please forgive me if this is a noob question. I recently developed an issue transferring files to the sd card. Using the usb storage method, after transfering 2 or 3 mp3s, the phone would shut off and reboot for no reason (This caused the Zeam launcher to crash apparently? for at least 15 tries)
I tried using the SD adapter, the transfer rate is extremely slow or to no transfer at all and causes windows explorer to crash or hang (tried at least 15x).
I figured my sd card was corrupted so I tried formatting the card. If I used the SD adapter, it would say the card is write-protected even though clearly, the locked was off. I even tried another SD-adapter to no avail.
Finally, using USB storage, I was able to format the SD card.
Since I mentioned earlier that the Zeam launcher crashed, (yes, I selected always use "zeam launcher" even after it crashed causing the error message to loop) I resetted the phone with the wipe data/factory rest option in clockworkmod (I'm using ViperRom 3.03).
I wasn't sure if the 1 click root (http://forum.xda-developers.com/showthread.php?t=770388) installed any folders into the sd card so I ran the 1 click root in windows just to make sure. After rebooting from the 1 click root, all the files that were previously formatted were back.
I guess I didn't read too clearly but
my questions is
1) how am I able to disable that backup function? I had a bunch of files (which I have no idea what they did) from when i first started playing with the phone and I want to start off fresh with just the files I need.
2) anyone have any idea why the sd card was unable to accept files through the SD adapter or USB storage method?
3) what to do when the launcher crashes (this happened to me 2x already where I lost all my data)
Thanks to anyone who can help. This will help me close some gaps in my limited Android/Epic 4g knowledge.

definitely something is weird. Using usb storage, I ran the scandisk to fix errors and some errors were found. I formatted to ntfs just for kicks and the sd card read blank and in properties the drive had nothing in use. I turned off usb storage, turned it back on and voila, all the files that weren't there are now back. It this a sign of a corrupted sd card or am I going crazy?

Which files/folders are you referring to? Because as soon as your phone mounts your sd card, it will write about 4 folders (I think) if they are not already there...
.android_secure
Android
DCIM
LOST.DIR
if I recall correctly. The other thing you can do is use your phone to format your card instead of doing it on a computer... go to 'Settings->SD card and phone storage->Unmount SD card' then after it is unmounted, use the 'Format SD card' option. If this doesn't work, then you may need a new sd card/phone.

[Q] Weird problem with SD card!

Hello,
friend got her hands on a htc desire. She let some small shop unlock it before really testing it. Now we got the following problem:
The SD Card doesnt work. At first everything seemed to work okay. She took 52 pictures, even installed on app on the sd card. Then it basically froze.
We can delete half of the pictures and make some new ones. After the phone is rebooted all pictures are gone. Apps cannot be installed on the sd card.
If I remove the sd card and put it in my Nexus One everything works fine. New pictures survive the reboot, old ones get deleted.
When she puts the sd card in her desire, everything is back to 52 pictures and 1 app on it.
You cannot copy stuff like update.zip on the sd card, because the phone will only notice 52 pictures on it... Rom Manager has a "fix" option which doesnt work and partition it didnt help it - if it did anything at all.
We even bought a new 8 gb one, same problem. Some other people reported the same problem in forums, but there is never an answers what did fix it.
Its S-OFF with AlphaRev.
Sadly we both have no idea how to fix it and no android development skills. My plan would be to go back to RUU to see if the problem is still there. If yes, just get a new one from HTC. If no, unlock it again.
Sadly when it comes to roms and the "simple guides" we fail to reproduce even the first steps. "Go to fastboot and enter command XYZ" - yet we cannot enter any commands there.
Any help is welcome.

Can you connect your phone to pc in adb mode? Or simpler: what happened when you are connecting your phone to pc? Does it ask about mass storage mount? Is it in debug mode? If not, I think that it is classical USB-Brick, else... I don't know what is wrong...

I had also a problem with my sd-card.
Put it in a card reader and make checkdisk with windows solved my problem.

Weird, my answer disappeared.
When we connect it to a pc, we can delete files, format it, run scandisk, copy stuff on it. Everything works fine. When we put it back into the phone, the old 52 pictures and nothing else is on it.

And I thought I was the only one…
My problem is as follows, I had with my 1st Desire a 8gig Class 4 Transcend SD card which was perfect and connecting to and from my home and work pc was effortless.
Then my Motherboard burnt out on that phone sent it back and when I got the new one I put my 4gig Class 2 SD which I got with the phone back in and no issues.
A few days later I bought a new 8gig Kingston Class 4 SD ( I lost my Transcend SD card) and after 2 days I would get “SD mounted as read only” so formatted the SD copied my data back to my 8gig Kingston card which worked fine on my PC but the same problem persisted when I put it back in my phone. I was using ADW launcher and kept getting the same errors all the time, then I switched to Launcher Pro and since then I have had no SD card problems.
Also when I was using standard HTC sense I also never had a problem, I hope this is of some help.

I rooted my htc desire using Unrevok 3 and also tried to partition sd by mini tool home version . unfortunately after partition i cannot access or recognize sd in my desire.

Still not making any progress, ..

Desire wont access apps on SD Card.

Hey guys .. I had switched off my Desire for charging and after I turned it on, the OS just wont access the apps stored on the SD card. I tried unmounting-mounting, even physically removing the SD card from the slot.
I am using Cyanogenmod 7 on it. I had moved few applications using app2sd and few I had force moved using app2sd+ froyo. I know for a fact that card is working because I can access photos, music, etc from it.
I see some one else had a similar problem on their Hero (http://forum.xda-developers.com/showthread.php?t=995786) .. Should I follow the same steps ?

Hi there,
Did you try to run a checkdisk on the SD-card while inserted to your computer?
Grtz!

What's the filetype you used for partitioning your SD-card?

Same on Galaxy Note 3: no access to apps on SD card. It suggests to reinstall.

[Q] 2.3.5 RUU update - SD Card Problems

Okay, I updated to 2.3.5 europe just last week using the RUU extracted installer. All was well and lovely until two days ago.
My SD card has gone crazy. As soon as I unmount and remount the SD card, the phone reads the SD card in a really weird way. The app drawer shows only a few apps that are installed. Majority of apps that I had on the SD card have now vanished - but are still installed because my internal memory is the same - and they still appear in applications list. It says it doesn't exist?
I've rebooted my phone, hard reset, factory reset, format SD card.. everything you can name, I've TRIED IT. Every time I reboot the phone it happens. apps disappear into a black hole. Also, I've reinstalled all apps thrice and cba to do it again! It says "failed to move application" for most apps at first when I try to move them with the App2SD app.
Has anyone else experienced this problem?
Should I revert back to my old ROM?
Is there a way to fix this? My phone is S-ON, no root.
EDIT: Now I cannot even unmount the SD card...

I had a MAJOR problem where the phone stopped recognizing the SD card. It would literally say unavailable and wouldn't recognize ANY cards at all.

Have you taken out the SD-card and put it back again? Sometimes the phone gets bad connection to the card and "exercising" it may help.

I've tried everything, even changed back from Sandisk to my samsung SD card. Same problem, it keeps rebooting at times and eventually stops and works perfectly.
Really REALLY annoying. It must be the ROM.

Just use Jik's salsa ROM, it runs really smoothly, frees up memory via link2sd and has new lock screen.
Then install the v6 supercharger and battery calibrator for a really great experience with this phone.
Get an XTC Clip and become S-Off, it's great.

[Q] SD card unexpectedly removed / Damaged SD card

Hello, I am on an HTC One V running PACman ROM 15.3, with the kernel JmzPrimoC+.
I started having this problem a couple weeks ago. It would randomly unmount my SD card saying 'SD card unexpectedly removed'.
This started to happen more and more often until it would say that as soon as I put the SD card in.
I did a factory reset, which helped for about 5 minutes before it started happening again. Now, more recently, it started saying 'Damaged SD card. SD card is damaged. Try reformatting it.'
I put it in my computer (which doesn't show anything wrong with it), and did a full format. It didn't help at all.
This problem is happening with both my regularly used SD card (SanDisk Ultra® microSDHC™ UHS-I 32 GB (the red and grey one)), and my ordinary SD card (8 GB class 4 Kingston).
I don't think this can be a hardware problem because when I boot to recovery, TWRP recognizes it perfectly.
But I don't either see how its a software problem, because a factory reset should have helped...
Please help me, any help will be greatly appreciated.

Maybe its a bug in the rom?

Hhmmm...
Good idea. What other ROMs work with JmzPrimoC+ kernel? AOKP?

OK, update, now TWRP won't read the card! Either card!
Now I'm getting really nervous...
Does this mean it must be hardware?
Is there ANYTHING I can do now?
Please help!

Wow, I screwed up really bad.
I was gonna use TWRP to flash a new rom, so I did a factory reset, and then started flashing the rom.
But in middle of flashing the rom it was interrupted. So I rebooted, rereset, and then I realized... it's not reading my card.
I can boot to bootloader and recovery, but that's it. No OS. I'm screwed.
Is there ANYTHING I can do?
Is it possible to flash a rom over USB? Or SOMEHOW get my card working again?

Just enter recovery and use adb sideload to flash a ROM.

But I need an SD card in order to use ADB sideload!
It fails every time because
Code:
E:Unable to mount /sdcard
Is there ANY way to do this without an SD card?

OK, I was able to do it following this guide.
I flashed the latest version of PACman. Still rejecting my SD card though.
I guess it's a hardware issue. Too bad my warranty is void from bootloader unlock :\

Try to partition SD Card in recovery
I am facing same issue and I came across this thread while looking for solution. Here is what I tried. That resolved issue for five minutes and then damn! same issue again but someone can find possible fix using the info here.
HTC One V rooted, currently running MIUI 3.1.2 with JB 4.1.2
Sandisk 8 GB SD Card.
Firmware CWM Recovery
I was facing same issue even before I rooted my phone while Original HTC ICS 4.0 Firmware was installed. MY observation is the problem starts few months after you start using SD Card. (Insert a new SD card in your phone, it will work fine for days / months and then will start giving same error.
While I tried thousand time to remove SD card, clean slot, clean card and reinsert, it did not work. May be worked just once for few seconds. When I tried to connect phone to PC and browse SD card contents, the card was not detected.
Booted to recovery, tried to format card, not detected. Tried to mount SD card, not detected. Then tried to partition SD card in Advanced options in recovery. The available options are 128MB, 256MB, 512MB, 1024MB, 2048MB and 4096MB. Since my SD card is 8 GB, chose the largest option. Now got an option to choose SWAP partition size. Chose 256 MB. Next chose option fix permissions, you have to wait until you see message permissions fixed message on screen.
Now rebooted phone, and voila! It worked!! SD card with 3.94GB memory is detected. But what happened to my rest of 4 GB?
Tried many apps to manage SD card from Play store. Using an app called APart, was able to delete partitions on SD card and create new ones. It worked for few minutes and then again I got SD card unexpectedly removed message.
Does this info makes any sense? I am not a developer and do not know much into phones but someone who know might be able to help. Buying a new SD card is not an option here because its going to work temporarily.

Have you tried formatting the SD card with your computer?
