Possible Hardware Problems With External SD Card? - HTC Rezound

I've moved this from a thread I started over in General where I was discussing quirkyness I'd experienced hooking my Rezound up to a computer. I guess I can say I'm returning to what is now a big problem sooner than I anticipated I'd have to. Let me recount...
I followed up on the second post in the above thread that suggested possible problems with my SDcard as the source of quirkyness I've been seeing. I first backed up my OEM card to my computer, then I reproduced that backup on two other cards using my computer, one a class 4 and the other a class 10; both cards are 16g. Also, both were formatted FAT32 out of the box. Even so, I went ahead and did a fresh re-format on the class 4 card just in case the default formatting was the problem.
Anyway, now I cannot connect to either of my computers, one a linux (Ubuntu 11.04) box, the other a win8 when either of the cards is installed in my phone. By connect I mean that I cannot connect as a disk drive and the device isn't recognized by "adb devices" when booted into the OS. In the bootloader, I don't see the "fastboot usb" designator in the fastboot menu on the device, and doing a "fastboot devices" on either of the computers also comes up blank. *Sigh*
So I guess I'm here to ask: Can anyone point me a direction where I can begin to troubleshoot the cause, which I now suspect is hardware related?
many thanks,
john

In a windows computer, what shows up in device manager when you connect the USB cable? Also have you tried at least 3 USB cables? Also try plugging your phone in booted to the Rom, going to developer options, and unchecking USB debugging and waiting about a minute then rechecking USB debugging. Do you get a noise, either positive or negative (sometimes there's a bad system sound when a device isn't recognized, sounds like someone giving the wrong answer on a game show or something)
Can you post screenshots of your command window when you run adb devices or fastboot devices.

[Q] Vegan connection problems USB and WIN

I recently put the Vegan-tab V1.0.065.11 with the Cyanogen Mod kernel 2.6.32.32 on my new g Tablet. Prior to that time I was able to use my computer to load files as it saw my g Tablet as a storage device.
Now when I try to use the cable link between the computer and the tablet it recognizes it as a removable storage device but when trying to access the tablets file structure I get a windows pop-up that states "Please insert disk into drive F". I have tried this on two workstations both running XP with the same result.
I also am unable to read files on a memory stick. I had not tried this before I had switched to Vegan so I am unsure as to wither this was a problem prior to the switch.
There is no message on the tablet regarding the turning on of any service or the mounting of the USB device. Does anyone have any suggestions as how I can get these file transfer mediums working again?
I am having the same problem. It has worked fine for about two weeks and how I'm not getting the prompt either. The same thing happened with another ROM. I can connect fine with ADB. I am currently running VEGAn Gingerbread. The same problem happened when I was running AOSP Gingerbread. It happened after about five days with AOSP GB.
Same problem here - im using ginger edition
Are you guys turning on USB mass storage by selecting usb connected and then turn on?
That's the thing... after a period the prompt to turn on or off the USB storage stops displaying after a period. The only prompt that I see is for USB debugging, and turning that on or off has not affect on my ability to connect to the internal storage from multiple Windows boxes. The prompt was there last weekend, but it's gone now.

[Q] Help - USB question under Cyanogen 7

I am a complete noob when it comes to Android, having first got my G-Tab yesterday. I'll give some background before I get to my question.
Yesterday, I sideloaded a couple of apps by essentially copyng them over to the root directory on the G Tab. But, like most others, I found the stock OS very slow and unresponsive. So I installed CyanogenMod 7 as per some simplified directions that I found. Everything went fine. That's not the problem.
My problem is that I cannot sideload anymore. When I plug in my G-Tab through the USB, I hear the Windows two thumps, and nothing happens. I look to see if my tablet is showing up in the Winders Explorer, and it just shows a bunch of memory sticks that when I click on them, I can't access. Also, nothing is showing up on the tablet either (no dialog boxes like under the stock OS, nothing). This is a big problem for me since I don't have access to WIFI at the moment.
Does anyone know how I can make my computer and tablet see each other? If you tell me to do something, please tell me where to find it. For example, on another thread, someone advised someone else to turn on USB debugging for something, but I can't find any option for USB debugging in Cyanogenmod 7 under settings. Thanks in advance for any help you can provide.
Additional info:
Computer: Laptop running Windows Vista
Did you try swiping on the notification area and enabling USB transfer on the tablet?
If you don't do this, your computer will see the USB device but not as mass storage.
For example, on another thread, someone advised someone else to turn on USB debugging for something, but I can't find any option for USB debugging in Cyanogenmod 7 under settings. Thanks in advance for any help you can provide.

Here is where this is....
Menu >>Settings >> Applications >> Development. 1st choice, USB Debugging.
Thanks. I did swipe in the notification area, and the only notification there was that USB debugging was activated. But still the G Tablet and computer cannot see each other.
Double check in your device manager (PC) to make sure there are no issues with the drivers.
Thanks. I found it and also found out that it is turned on by default. So I guess that doesn't help.

Does Cyanogenmod 7 require special drivers? The drivers worked fine on the stock build, and nothing changed since then. Everything looks ok.
I plugged my Gtablet (CM7.02 with Pershoots 4/30/11 kernel) in to my computer just now to test. I haven't used it on this computer since installing CM7. I did just work on my boss's Gtablet the other day running both stock TapnTap and VEGAn 5.1.1 and it worked fine on his.
I plugged in the tablet, Windows 7 (32bit) said it was installing drivers, driver install completed successfully.
On my tablet I then swiped up the notification bar and tapped on the selection that said "tap here to mount USB to share files with your computer" (or something like that). The Android mascot screen popped up and I tapped "Turn on USB".
New drive opened up on my computer that was the gtablets /sdcard.
So it works and used the same driver as before.
No special drivers for CM7.
One nice thing about CM7 (or maybe Ginger) is that now when plugging in you get access to both the internal and external SD cards from PC.

My computer Vista (32 bit) at no point said it was installing drivers after I upgraded to Cyanogenmod 7.
When I swipe the notification area (and I assume that the notification area is the area at the top of the tablet's screen), I get a menu that tells me that USB debugging is activated and that's all. No option to mount USB. And no screens popped up to ask to turn on USB. None of this.
And when I plug in the USB, as I mentioned, I get the two tones from Windows, and 3 new removable disk drives appear. But when I click on each, I get am asked to insert a new disk.
That's all the info I have at the moment.
At this point, I'm so sick of it. I think that probably somewhere a switch is not flipped or a box is not checked, but I have no idea where that could be. I'm seriously considering using ClockWork mod to restore the system. But I'm loathed to do this since I spent 2 hrs. downloading Cyanogen Mod last night (I have a slow internet connection).
I would suggest that you turn off "USB debugging". That setting exists to activate adbd on the tablet, and normal users, usually, never need it. Enable "USB debugging" only if you need to use adb.
After disabling USB debugging, reboot the tablet, and then connect the USB cable to the mini-USB slot on the gTablet. As soon as you do that, on CM7, a USB Mass Storage screen with a green Android will pop-up with a message saying "USB connected" and button to "Turn on USB Storage".
Click the button and a warning that "If you turn on USB storage, some application you are using will stop and may be unavailable until you turn off USB storage.", will appear. Select OK. The green Android will now turn orange and the screen will say "USB storage in use".
Use the "Turn off USB storage" when you're ready to wrap up.
Ok. I think I might have solved the problem, but some intervening events makes me not sure. Basically, I restored to factory and then put in a different ROM, VEGan7. However, while doing this, I think I might have found the solution to my original problem.
It turns out that it does seem to be a problem with Windows, or at least with Vista. I had the same problem with VEGan7. But this time, I right-clicked on the "removeable disk" that appeared under "Computer" (where you see all your drives) when I hooked up the G TAB via USB. After I right-clicked, I selected properties and then clicked on the "Hardware" tab. You will see a list of all possible storage devices to associate with that icon. I chose the one containing the string "Tegra2" and I was off to the races. I was then able to perform the actions mentioned above about activating the USB on the G Tab.
I suspect I could have used this technique with Cyanogen 7. The only thing that I question is that I saw 3 removeable disk drives appear and not just one. I hope this helps someone else who might run into the same problem.

Did you by any chance have an external micro SD card on the tablet?
If so, I'm thinking that you saw the 2 SD cards + the APX debug mode device.
flash this zip (in post #3) to mount the internal storage as an SDcard instead of EMMC. If you run that then you should be able to mount the storage when running CM7
http://forum.cyanogenmod.com/topic/20913-cyanogen-7-viewsonic-g-tab-usb-connection/
also your other option is to boot into Clockwork recovery then go to mounts/storage and mount usb
you should then be able to transfer files back and forth

No, just got the tablet. Didn't have time to fool with external Micro SDs.

Thanks, I'll give it a try. What are the ramifications of mounting the internal storage as an SD card instead of EMMC? Do I lose performance? I mean, there must be a reason that the default is EMMC.
I wouldn't want to boot into Clockwork every time I want to transfer something, apps or even music and videos. That would be a real pain. Actually, I was surprised at how long this tablet takes to boot up after a complete shut down.

From what I have read that's the way that Gingerbread does it. Some programs actually have problems with that configuration, that's why people do this.

Do you think you might post the file here. When I go to that link I'm not allowed to download it. The irony is that that link says it came from here but I've used the search and I can't find it here. Maybe it is just day after Cinco de Mayo problems I'm having?

[Q] adb is working, but fastboot isn't...

After flashing some roms,my phone now can only access to internal and external sd from pc. Although, I can put files in sd, I can't see nor access to those files in my phones. I did some research and found out that the command in sdk could help me: "fastboot oem enableqxdm 0"
This is where I got stuck. I could access to adb and when I commanded adb devices I can see my devices attached. However when I typed fastboot devices, nothing shows up, and when I typed "fastboot oem enableqxdm 0", I got stuck in "waiting for devices" message.
I don't know what was going on, since adb command is still working fine. I would really appreciate any help here.
P.S. I don't know if this is matter, but I run on xp window.
I think fastboot is only for HTC devices. Someone please correct me if I'm wrong.

haha. yeah, fastboot = htc.
I saw the title for this thread and had to do a double take that I was in the Vibrant section. This was almost news to me.
I saw both fastboot and adb exe file in android sdk. I thought they would work for all android phones.
If it wasnt, do you know any ways for me to reactivate sd card or to access sd card through my phone? Rite now i cant see any pictures or songs, which i put in my internal n external sd though pc.
have you tried simply mounting/unmounting... maybe copy everything to the pc, format it and then reboot?
settings > sd / phone storage.
I tried mounting,unmounting, format it from both phone setting and on pc. I still found no luck
edit: i even flash back to stock rom and do factory reset. Still no luck. Is there any other ways that i can try.

First of all, what rom are you running? And secondly, if you're trying to access your sdcards from recovery, you really only have access to the internal one, nut not as USB mass storage.
If you're trying to access the sdcard from your computer as USB mass storage, make sure you have debugging enabled, and then using the notification menu, tell it to mount the sdcard.

SDCard not recognized

I installed cyanogenmod 7.1 with no problems. Everything works fine, it is so much better than WebOS.
When I plug the touchpad into a usb port on any computer (XP, Windows 7, or OSX), they see the tablet as a drive but an unformatted one. I have been tempted to format it, but I figure that will bring me nothing but grief...
I have read everything proposed on this forum and others, like: fixing the permissions, toggling dev mode in webos, manually connecting usb storage. Nothing will get my computers to recognize this as a mass storage device...
Help!

NT/USB CONNECT: MTP then USB COMPOSITE then NT but no joy!!

I've had this problem for a while (not being able to connect my NT to my computer) and can't seem to resolve it. I happened to have to upgrade my hard drive and hoped the clean install of XP would fix it but it didn't!
When I connect my NT to the computer via USB (running Paranoid Android 3.01 off 32GB class 4 Sandisk SD card, and yes, I have USB Debugging enabled) I get the following:
The NT is recognized as the following devices, in this order:
MTP
Composite USB
Nook Tablet
The hardware installer opens after each "device" is recognized. Finally I get to Nook Tablet after cancelling the two previous hardware install requests but a third pops up and then I get a message that there was a problem with the installation!
I had been able to fix this problem previously by running usbdview and uninstalling each device, then deleting the device drive letter assignment, and finally running my Norton 360 Registry Cleanup Utility. But, now, that just isn't working!
I surmised that I was having a problem with the drivers. So, I surfed the web and found the USB Driver Zip file from Indirect's OP on rooting and installed them on my computer again. No luck.
I managed to get into a log file (don't ask me what it was called, I forgot) that was in the WINDOWS/DRIVERS/i386 folder. It mentioned a paging error occurred during the process of attempting to connect the NT to the computer. Does this mean my SD card is bad? I have had no problems using it to run the PA ROM on my NT, at all. From what I read however, that I could try to understand, a paging error has something to do with a problem with the SD card? Certainly I can just reinstall the ROM, in another card if necessary, or load a new one. However, I'd like to be able to get my content off the card without having to drop box all the files to myself (a decent but slow workaround).
I know I could try to use ADB over my wireless connection somehow to achieve this as well, but that is over my head right now.
Any suggestions regarding what is going on here would be greatly appreciated!
Thanks

It's not clear from your post if you're merely try to connect the NT to your PC via USB for media content transfer, or for ADB access.
If the latter, http://forum.xda-developers.com/showpost.php?p=35971559&postcount=13 might be of help.
Oops, sorry. Just for content access/transfer.
Actually tonight my device seemed to reboot while I was in the middle of composing a document (data viz word). It's never done THAT before. Interestingly, it seemed to skip cyanoboot and go right to the SD ROM. The WiFi needed to be manually connected thereafter (usually auto connects). The reason I think it rebooted and it wasn't the screen flaking out as a problem is it went black and then right to the first animation for PA 3.01. But this seems to make no sense!
Maybe the SD card IS failing?
Yes, I am trying to avoid having to learn ADB access. Too tired (you know why Digi.) If I must, I will shell out for a new card and maybe try one of your newer ROMS......it's probably time for that anyway. But the card is only 6 months old
I will test out trying to access the NT on the computer via USB without the SD card mounted. Maybe that will shed some light.
Thanks as always.
