[Q] SD cards shows up when none installed - G Tablet Q&A, Help & Troubleshooting

I am trying to Flash my G Tablet with a new ROM. When I view the existing files on my G Tablet using the resident file explorer two SD cards show up, SD and SD2 but there is no SD card installed in the slot. The reason this relates to my attempt at flashing the ROM is the mystery SD card is the only thing my laptop shows when tethered using the USB cord.
Can I delete these mystery SD cards without any harm?
If I do delete them, will my laptop then be able to get to the Root folder so I can transfer the Clockwork Mod and TnT Lite files?

Hmmmm interesting i have never heard of that problem (not that its abnormal).Well in the viewsonic g tablet there is an internal sdcard, but you mention a SD card 2. I would reccomend NVFlashing because this may just be a glitch and it will restore your tablet back to normal. And as a plus, it will be very helpful learning how to NVflash your device because it comes in handy very often. Hope it works

Question regarding Backing up HD2 SD card

I'm wanting to backup & format my SD card following a problem with Sense not loading described in another thread. Having read various threads about this problem it seems that some, if not all, revolve around issues with the SD card.
Through File Explorer, on the phone, I've selected ''Show all Files'' from within my SD card directory. However after connecting my phone to my PC thru active sync there are some files that are visible on my phone in the SD card directory which aren't visible in the SD card folder on my PC screen. I've tried to find the show all files setting on my pc but haven't been able to.
Thing is I don't want to backup my card then format it and possibly not backup all files that are present on the card.
Any help appreciated.
Hi there,
Two days ago I copied all the files on my SD card to my laptop, changed my card from a 2Gb one to a 8Gb and copied all the files back again onto the new SD card. I never even looked for hidden files neither on the phone nor on the laptop and it all went without any problems and all is working fine.
For sake of good order, I can't guarantee it will work with you as well, but it should.
Bye,
Itamar

[Q] SD Card Will not show up on Viewsonic G Tablet

So I recently Romed my Viewsonic G Tablet.
I followed this guide.
http://forum.xda-developers.com/showthread.php?t=865245
Everything is fine..except when I put a SD card into the SD slot the Tablet doesn't recognize it. It just tells the the internal Space not the SD card space.
I used ZPad Clean v3.0 for the ROM and I used cwmod_internal.zip instead of cwmod_microsd.zip
I then used my friend's G Tablet and put the SD card in it..It read it just fine.
So I wanted to test it out while it was rooted. (to double check)
I then Rooted my friends GTablet also. I rooted it the same way but the only change I did was have a SD card in the tablet the whole time. Still the same problem.
Is there any way to fix it? DO i need to use cwmod_microsd.zip....instead of cwmod_internal.zip??
I'm really confused if someone can help me that would be amazing!
Is there an APP that tells you the storage of your installed SD Cards?
Thank you
You mean flashed the rom when you say romed. Have you checked to make sure the sdcard is getting mounted? If there is no data on it you might try reformatting it in either of the g tabs. If you can get to a shell you might reboot, and look at the last 20 lines or so of dmesg. Insert the card and take another look at dmesg and see if the kernel is picking up the insert at all. If so it is likely just a mounting issue.

Well I reformatted it and I mounted it. Still nothing..How can I check if the kernel is picking up the SD card at all?
Would changing Kernel's fix the problem? I'm just using the Stock Kernel that the ROM came with.
Thanks
You were able to reformat and mount it via the g tablet with the zpad software on it? And even having done that it doesn't list it as having any free space?

Not yet. So should I go to Storage and devices and unmount and format the SD card via the tab?
Try it on the tablet.
If I reformat the SD card wouldn't I loose the root? or no right because I did external
My understanding of root is that it modifies files on your tab/phone, not an external sd card. Worst case you lose root and reroot the device.

When I tap click mount it says 11.3 gigs available.
when i unmount it says unavailable.
The card is only 8GB.
It should be internal storage 16GB.
SD card like 8gb.
Not sure what's going on.
If I format I think I'll wipe it all.
Ok, there is an internal 16GB, yes. Of which you have 11GB free. The SD card you're having the issue with is a separate uSD 8GB, right?
I'm meaning for you to try to mount/unmount or possibly format the 8GB SD card. If it isn't showing at all then the issue is something beyond it simply not being mounted.

Yeah. It's a separate card that I plugged into it.
Was there ever a fix/resolution for this? I am having the same issue.
Everyone,
I've written this a bunch of times -- but here's one more:
/sdcard -- internal memory of the tablet
/sdcard2 -- miniSD card in the external slot
/usbdisk -- USB key slot
Put your recovery folder and update.zip on /sdcard, turn off the tablet, the press power
and volume + to initiate standard recovery.
Second, put your recovery folder and update.zip on a miniSD card. Edit the command file
in the recovery folder with Notepad to change the location from /sdcard to /sdcard2 and
save it with the name "command" (NO .txt or other file extension). Then boot
recovery with power/volume + and the OS will use the sdcard (assuming you don't
have a live recovery/update.zip file in /sdcard).
Third, if you can boot recovery to CWM but can get your ROM to work, go in recovery to
the mount menu and go down to the mount USB memory option and choose it.
Then plug your connector cable from the miniSB port to your PC. When you plug into
your PC an Explorer window should open and you should have a drive letter representing
the G-Tablet (it's G: on mine) on you menu. You now can select that
letter and you have access to your tablet memory (/sdcard). I've even had a time or two
when not a single file showed!!! I added update.zip and recovery and loaded
a ROM!
The tablet boot process apparently checks /SDCARD. If it doesn't find a recovery files there
it does the same check if you have a miniSD external card installed. The large USB slot is not
useable for booting or recovery so far as I have determined or read.
I hope this helps you.

I own a visio tablet which I rooted with vegan and clockwork. I have a 32GB SD card but when I check the storage is says 12GB on SD and 2GB on internal. The tablet should have 16GB + my 32GB. Anyone have an idea why it wont come up?
Is the fix above the best way to take care of this issue?
Can anyone kindly help? I've read through a lot of the links and can't find anything. I have rooted my device with clockworm v8, Vegan, got the market place to work and now I just need to figure out what is going on with my 32GB SD card. Should I format it with FAT32? How can I get it to be recognized?
Thanks in advance!
Formatting to Fat32 would be a good start ;-)
SD Card Dilemma
I have the VEGAn-TAB-v1.0.0B5.1 installed in my G-Tab and, with the exception of the SD card issue, things are just peachy! I've read the entire thread but, even with butchconners description, I seem to still be missing something. Let me try to structure this a bit differently...
1. The sdcard2 DOES show up in ifilemanager (with only one file, LOST.DIR) but NOT in SETTINGS. Since it does not appear in SETTINGS, there is no way to mount or dismount it (although if it shows up in the file manager and I can see the file on it, one might infer that it is already mounted.)
2. Even though I can see it in ifilemanager, I'm not so sure how I can actually USE it. It seems to me that the system would need to know (via SETTINGS) that it is there and I would have to tell the system where to put my files (i.e., sdcard or sdcard2).
3. When I connect my G-Tab to my Win7 PC, I only have access to sdcard AND NOT sdcard2. This seems a bit unusual since I have always had access to the removable sd card AND NOT the system memory on all my other devices (EVO, Blackberry, etc.)
My goal is to be able to set applications (some or all) to use the sdcard2 (at least for data) and be able to access it via the usb connection to my PC. Does anyone know how to accomplish this?...Has a solution for this already been posted somewhere?
Many thanks.
I am not an expert but the pc sees(?) only sdcard(internal) but no sdcard2(microsd).
Right, Guys?
I am now able to see both sdcard1 and sdcard2 using pershoots latest oc kernal released 4/25 when hooking up gtab via usb to computer. I am using Vegan tab gingeredition.
where does one find that kernel and how do i install it? Im running vegan ginger right nowand have the same sd card issue.
thanks!

[Q] Accessing SD Card

I feel like I'm missing something, and I'm hoping that someone went through this and can make me feel less inept.
Just got my new GTablet. I bust it open, run the update from viewsonic, reboot. Then, I go to install clockworkmod and I can't get my PC to recognize the SD card. When I look at the browser on the tablet, unplugged from USB, I see the "SDCARD" directory, but it is there whether I have the card in or not. I plug it up to the PC with the card in it and the only thing that shows is the 13GB storage on the tablet. Unlike my Android Phone, which shows the phone memory and the SD memory as two separate removable disks, I'm only seeing 1.
I've formatted the SD card on the tablet, which does see that there is a card, but aside from that, I can't get to it... ideas? Am I missing something obvious?
On the PC: the internal memory is seen as SD1, the external SD slot is seen as SD2
After you formatted your Micro SDHD card on your G tAb, did you mount it ?
I've mounted, unmounted while the tablet was plugged up and not plugged up. I threw it in my HTC Incredible to see if there was a problem with the card, but I can browse to it fine through my phone. I formatted it on the PC (FAT32) and tried again. I see The SDCARD and SDCARD2 on the tablet, but it never shows up on the PC. The only thing I see is "Removabled Disk" with 12.7 of 13GB free.
So, I've now tried a new card, with still no go. I mean, I added clockworkmod to the SD card via windows, tried to boot to it through recovery, but it goes to the unpacking splash screen and reboots after 10 seconds. I can go into the file explorer and see the update.zip that I added to the SD card at /sdcard2/... Any help would be appreciated. Help =(

This is normal behavior for the G Tablet. Only the internal memory will mount on your PC.
Thanks for that. I figured it out after reading through a lot of the guides that directed me to install from the internal "SDCARD."
Since reading your post, I've got everything up and running with Cyanogenmod installed and running... Thanks to everyone that threw your two cents.

[Q] Pls Help - Android Won't Skate

Noob here. Device is 16GB NT, rooted 1.4.1, using Albert's SD card. Works like a charm, but various apps show that they are not compatible with the NT. I would like to try the external CM7, and flash it to internal after I try it out.
I have tried several SD cards, (8GB Sandisk Class 4, 32GB Sandisk Class 4, 8GB Transcend Class 4) and two ways of imaging the CM7 file (using Winimager32 with the SD in an SD/MMC reader/writer on my laptop, using Winimager32 with the SD card in the NT). After imaging the SD, I have attempted to boot without expanding Partition 4, also with expanding Partition 4 using Gparted, and expanding Partition 4 using EASEUS Partition Master and Mini-tool Partition Wizard. I have gone back to a clean SD by using Windows to reformat the card, and by using the NT to erase and reformat.
I think that I must be missing a simple step in the process, but after searching XDA, Tabletroms, and Google, I am unable to come up with a solution.
Questions that I have are:
- Is it necessary to clear the dalvik cache when using the SD card? (I don't think so, since all boot and setup activity seems like it does not include the internal boot/system files)
- I came across a thread that says that a "cache" folder should be added to the root of the "data" partition. Is this a required step?
- Do the second and third partitions require the "system" and "data" labels?
- I set the attributes of Partition 1 to Active (LBA). Do I also need to set a boot attribute?
I apologize for the long-winded post, but I appreciate any pointers that you can provide. BTW, the efforts of all those who have taken the lead to improve the NT are first class, and the help provided by members of the XDA community here are impressive, to say the least.
-
If you mean you're not able to boot up at all, try plugging your NT in then turn it on. Some people's NTs will only boot when attached to the cable.
Re: Android Won't Skate
Thanks for the quick response. I left out a few items in the original post.
I have to tether my NT to the plugged-in charger to get it to boot with the SD card installed. I get the Team B splash screen for about 15 seconds, then it goes to a black, backlit screen. I have waited as long as 20 minutes, but nothing happens. I have also popped out the SD card, and reinserted it, as have others in this forum, but to no avail. When I power on untethered, I just go to the normal NT boot.
If I boot up normally, insert the card and use ES File Explorer, I can see four folders, plus the boot.img, flashing_boot.img, MLO, and u-boot.bin. Also, when I use GParted, I can see the four partitions, and when I use ext2explore, I can see many files in both of the Linux partitions.
Hope this adds a little more clarity to the original post.
Thx.
You shouldn't have to make any changes to the SD card after you write the image to it. Just put the card in and power on.
it 'sounds' like its your sd card. did you try it with just the one ? imho, because the card is choking... go get a 4 gb class 2 and try again.
1) sdformatter, fat32, not quick...
2) then use 'Win32DiskImager.exe' . . .
Android now skates
I finally got CM7 to run from the SD card(Sandisk 32GB Class 4). Used another PC to image the SD card. Worked on the first attempt.
Hope this helps others who have had this problem.
the main thing that those of us who came from nook colors will know is dont use laptop sd card readers.. prolly half the posts i seen were due to using one of them. the best SD card readers are the PC ones and using a proper image writer.
as far as the app issue.. if its like the nook color you can always edit your build.prop to make it show as another device on google play
I seem to be having somewhat of the same problem.
I got an 8 GB (4) and burned the CM7 image to it using win32diskmanager, then used easeus to partition my drive. Put it in my nook, perfect, everything works.
A few days later I got my 32GB (4) card in the mail and did the same thing. Put it in my nook, and it wouldn't boot. I can see the TEAM B+ splash screen but nothing else, screen turns black afterwards and nook reboots to nook stock.
I don't know why it does this, could be sd card problem.
Im I missing something? do I have to do anything special if im using another sd card on the same nook?

If it worked perfect the first time, it has to be an SD problem or a burning problem. I'd try rewriting the image to that SD card.

So I reformatted the 32GB card using SDformatter (lost 2GB in the process) and burned the image one more time.
Same thing happened. Nook keeps booting back into stock (after team b's splash screen). I re-insert my 8GB SD card and it works perfectly.
Must be the SD card unless someone knows what else is happening... I guess thats what you get when you shop for SD cards on ebay.

You might want to try booting up with the power cable in. Some of these SD cards and NTs just like to be difficult, but it's worth a shot anyway.

Very peculiar things are happening.
I had put my 32GB SD card away until I read your last post, thinking I might try to reboot from card with he power cord like you suggested to see what happens. So I put my card in and it loads to stock nook. No CM7 splash screen like before. I reset the device and tried again, nothing.
I think the card might be bricked now. I checked to see why this was happening and now my devices won't see the SD card. The nook asks me if I want to reformat the card, but it crashes if I choose to do so, and windows won't see the drive the card is on so i'm not able to format or play or see the partitions.
Edit: Wow. Ignore that. As soon as I posted this my device finally reformatted the card. Will try again now.

As long as the SD card mounts, you should be able to get your card back to normal by deleting all the partitions then creating just one, formatted as FAT32.

Re-burned the image. Nook will not start at all now with the card in there. I played with the power cord and left it there for 2 minutes and it powered up, however, no splash screen or anything, boots to stock NT.
I turn the NT back off, same thing, won't power ON. I wait two minutes with power cord on and it powers on then.
Bad SD card?
Card has:

B&N Downloads
LOST.DIR
My files

flashing_boot (img)
MLO
u-boot.bin
When I had issues, I followed old fart's suggestion and reformatted my card with sdformatter first. then burned the image with Win32diskimager, both on another PC. When finished, I ended up with a 3.8GB image on the SD card. Nothing worked until I used the other machine. After I was sure that the card was going to work, I expanded the fourth partition to use the rest of the space on the card.
BTW, I had to use the USB cord, plugged into the charger to boot up. Worked on first try. Been happy ever since.

Sorry for the confusion.
I made many unsuccessful attempts to make the sd card on a Sony laptop, using an sd card reader in one of its USB ports. It wasn't until I switched over to the "other" machine which is an old Compaq desktop, that I was able to get a good image on the sd card. The point is that I had to switch to different computer to create a good image. It seems like something on my laptop prevented me from making a workable image on the sdcard. Hope this helps.

It could be the read/write speeds. What I do is I use the nook as my card reader, since I dont have a card reader on my PC. However, I do have one of those USB card readers. The difference between them is that when using the nook, it writes at about 3-4mb/s while the usb card reader writes at about .5-1mb/s.

Damaged SD Card...not!

I got my Dell Streak second hand but the 16Gb card that came with it wasn't working. Not that the seller had mentioned it.
So, I've actually bought 2 16GB micro SD cards and both have had the same problem. The device recognises it upon first installation but when writing further data upon it, e.g. connecting it via USB or taking the micro SD card out and using an SD adapter, the files become corrupted. It doesn't matter what type of file it is, it all gets corruped and it says that the SD is damaged when the phone is trying to mount the SD card again.
This is the 3rd time it has happened so it's no coincidence.
My 4gb that I had in my previous XDA Orbit has been working fine ever since I got my Streak with no problems whatsoever.
Am I missing a driver for 16gb+ SD Cards?
EDIT- Just had a thought. I was transferring all my stuff from my previous card that was in my Streak to the new one, could this have caused any problems? I assumed you could transfer all SD data from one card to another and still have all the apps and data working?
EDIT x2- Had another thought! It seems like when things get put onto the root of the SD card, it causes corruption but when it gets put into a folder, it seems okay. Now this isn't a problem when the device writes things to the SD card- they get put into the appropriate folders, however I have never had this problem with the aforementioned 4gb card and always write pictures and movies onto the root of the SD card to view without any problems.
