[Q] Bootable Micro SD card - Epic 4G Q&A, Help & Troubleshooting

I have a Samsung Epic 4g running the latest Cyanogenmod 7 nightly. What I'm trying to do is this: From Clockworkmod, mount USB storage, and from that, connect the phone to a computer and use the SD card as a bootable USB device.
I'm using SARDU to make a multiboot image for Linux, Gparted, etc. but to no avail. The phone is for some reason, listed as a FDD instead of a bootable USB. When booting from the phone anyways, it merely displays a copyright screen of Syslinux instead of loading the SARDU menu.
I've managed to format the SD card in such a way that it is listed as a USB device in my computer's BIOS, but then the SD card isn't recognized by android and is considered "damaged".
I know this has been asked a few times before, but nothing is quite like what I'm trying to do, and none of them have an exact method on how to do this.
Any and all help would be appreciated.

[Q] Finally reached a problem I cannot fix on my own, please help

So my phone and computer will not detect my sd card after I dropped my phone.
Here is everything I have tried:
hard reset
sdhc micro adapter for my computer
pulling out sd card and reinserting
pulling battery and letting sit for awhile and plugging battery back in
I followed the sd card and usb fix issue found in the forums, but everytime I install the jdk the sdk installer says it is not found.
I know if I am able to format the card somehow it will fix it i think. but I cannot get anything to recognize it, or if I can figure out what single driver is missing on my phone I can figure the rest out from there.
The sdhc adapter works with the new micro it came with but not mine.
I am still able to use my phone but I obviously cant do **** without the sd card.
I have a recent backup of my sd card on my computer I just need a way to get it to my sd card and I am stumped.
Thanks for your help guys
Is there a way to force my comp to read the sd card?
Update
One thing I was just able to do was to take the micro sd that came with my adapter and my phone reads it just fine. However it is only a 2 gb. Like I said, I have a back up on my computer of everything that was on my sd card at one point. Being that my phone can read sd cards, does this help at all with somehow fixing my factory one?
Since I am now able to get into rom manager and my phone recognizes some sort of sd card. Would flashing some sort of sense ROM allow me to put my original sd card in and format it?
If all you want to do is repartition and/or reformat it, boot into recovery and do it there. While in recovery, especially is your recovery is amonRA v2.3, select the "MS-USB" option and serif your computer detects it while you're connected via USB.

I am currently using clockwork. I tried the mount unmount options in recovery mode. I have never really tried amon-ra for anything but now might be the time to give it shot.

[Q] USB and SD not recognized

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?

[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 )

Samsung Galaxy S i9000 internal sd card not working and touchscreen not responding

Hi. I have a Samsung galaxy S i9000 running a Jellybean 4.1 custom ROM. androidadvices. com/ update-galaxy-gt-i9000-stable-jellybean-411-firmware/#.UDJOV91mT9d
Everything's working fine until today when my laptop (Win7 OS) froze up while I was formatting the internal sd card of my phone.I restarted the laptop and phone and the internal sd card cannot be detected by either device anymore.
I tried to format the sd card multiple times to no avail. I tried to flash stock GB ROM. ODIN can detect the phone but cannot complete the process. It fails on "Setting Up Connection".
Up to the above process I was able to use my phone (it turns itself on, just can't use internal sd card). However, I made a stupid mistake of doing factory reset, cache wipe, and dalvik cache to reflash the JB ROM in hopes that it will fix it. Now, my phone is stuck on the Welcome screen (one with Choose Language and Start to setup) but the touchscreen isn't working so I can't select Start. The buttons on either side of the center button works, though. Only the touchscreen function is not working.
Now obviously, USB Debugging is not set up on my phone so I can't do a lot. My first question is: Is there a way to setup USB Debugging using ADB or from Recovery?
Additional info:
Recovery and Download mode are both working, although like I mentioned above, I cant reflash stock ROM because of no usb debugging and it fails in Odin. File Manager can be accessed from Recovery but it has no internal sd card directory. External sd card is ok, though, as well as the system files. But cannot install from internal sd card (obviously), cannot format sdcard, or do anything that has something to do with sdcard. It gives an error "E:\ can't mount sdcard"
When I connect the phone to the computer via USB, the phone "knows" that it is connected because the notification beep sounds and on Computer, it shows a new drive name (F but it says "Please Insert a disk into Removable Disk F.", which I believe, means it can detect it but cannot mount the storage.
I can also use adb.
So my questions are:
-How do I get the touchscreen functionality back?
-How can I enable my internal sd card to be mounted on the phone again?
-(same as above) How do I enable USB Debugging from adb or recovery?
I know I have a lot of issues on my phone but I would really appreciate it if you can help me. Thank you.

USB mass storage in recovery with TWRP?

Ok, so this is a simple question. I'm hoping for a simple answer, though I have found a couple work-around methods/apps, I have yet to experience a real solution where speed of transfer and ease of use are both intact. Here are my observations: Low SD write/read speed when inserted to phone, regardless of stock/cm9/cm10 clean flashes/ factor wipes sd card formatting and partition alignment. However before you tell me I have a faulty SD card, the card performs above and beyond its class 10 rating in a simple usb to micro sd reader/writer that literally cost me 3 dollars. Secondly- why does the usb device id change from Rom to rom and from recovery to recovery, is it something overlooked by developers, or are is Samsung just messing up their driver files? I'm going to attach a series of images takin from my windows 7 pc that i just reinstalled from my purchased install disk on a brand new hard drive. The images show the device manager's response to first: usb mass storage in recovery mode in TWRP. (the correct version)(duh) and the second set is the device manager's response to the same exact phone with the same exact rom seconds later after rebooting the system from the recovery state it was just in. (the phone was never plugged into this computer/installation before this demonstration)
