[Q] Can someone step by step the sd card working for me?

I have a US WiFi xoom, rooted, running tiamat 1.4.1.
I've formatted the card in a computer and an android device (Evo). No matter what I do, the SD card will not show up on the device in android. It shows up fine in clockwork. I've restarted my xoom as well after inserting the card.
Can someone lay it out for me, because I'm obviously missing something, and I've tried all the answers in the other threads, such as "format it".

I'm having the same problem. Did you get it fixed?

Ok first I'm assuming you have a file manager app (I suggest Astro or Root explorer, file station is a good one too) You should be able to see the files on your memory card located in sdcard and a folder called "external." If you have files on the card but they aren't showing up in the "external" folder a reset will usually make them show up. I hope this makes it a bit more clear.

I've tryed that and I'm not seening that file external anywhere.

In all honesty, you are probably not doing anything wrong. Some sd cards just don't work for some reason. I have a crappy 1 gig card that worked as soon as I restarted my device, and have a 8 gig card that will not work while honeycomb is running, no matter what I do . Same deal though, it will show up in CWM recovery. Maybe the idiosyncrasies that arise from different sd cards is what's holding official updates from including sd support?

So what card seems to work? I've tryed two the one out of my evo and the 16g that I just got.

How did you flash to 1.4.1? Did you come from stock or previous versions. Did you use ADB or Kernal Manger? If it was from stock then you might try flashing the 1.4.0 kernal first and then going back to 1.4.1. I actually liked 1.4.0 better because of some of the memory mounting features that it had.

Do you see a /sdcard/external folder? Do you see a /sdcard/sdcard2 folder?
Try creating both of these and rebooting your Xoom. Which version of Tiamat did you come from?

Sd Formatter and a reboot solved my issues with a 32g Kingston.
jwb

I upgraded to 3.1 and put on the TDR WiFi kernel but I still don't see my SD Card. I can see it in the Recovery module, but not within HoneyComb. Any ideas?

I'm using a SanDisk 32Gb, no issues.

No SDCard for me outside of CW
I went from Tiamat 1.1.6 installed via adb to Tiamat 1.4.2 installed via CW and I cannot see the external SDCard on my 3G Xoom.
Steps I took:
1) Started at Honeycomb 3.0.1 with Tiamat 1.1.6
2) Installed CW 3.0.2.8 via adb
3) Flashed Honeycomb 3.1 via CW per instructions (SDCard is seen in CW)
a. Flashed New Recovery
b. Flashed HC 3.1
c. Flashed Bootloader Patch
d. Flashed Updated Boot.img (for 3G Xoom)
e. Performed Wipe Data/Factory Reset
f. Performed reboot and verified successful install of HC 3.1
4) Flashed Tiamat 1.4.2 per instructions via CW (SDCard is seen in CW)
a. Flashed 3G Boot image with light off
b. Flashed 1.4.2 1600 Kernel
c. Rebooted and verified new Kernel. Used SetCPU to clock at 1,600 Mhz
I still can't see the SDCard as either /mnt/sdcard/external or /mnt/sdcard2 using Root Explorer, Astro or EStrongs. I reformated the card using XP SP2. I then tried to format via my Droid and finally SD Formatter. I reboot between each format. Nothing works. My SD Card is a Sandisk 16GB. I have tried having USB Debug On and Off...no difference. I reflashed the 3G light off Boot image followed by reflashing Tiamat 1.4.2 with no result.
Could the problem be that I went directly from 1.1.6 to 1.4.2 without any interim update? It is weird to me that CW sees the card but HC 3.1 won't.
Thank you for your help.
Update: I also tried to use the Sandisk 32GB from my OG Droid which I know is a good card. CW sees it on the Xoom; but HC 3.1 doesn't.

[Q] "Can't mount sdcard" error in CWM

I've seen this error elsewhere, but no solution. I'm running PRIME 1.4, want to upgrade to 1.6.
- I used the nvflash method. I re-did this, obviously that didn't work.
- I tried formatting the SD card via Windows and via CWM (which didn't work, because it couldn't mount it...duh). Used the default FAT32 settings to format. For others, this seemed to be the fix.
- I CAN read the SD card on the tablet once booted up regularly. I can also mount the storage on my PC.
Any ideas? Thanks in advance.

So I tried a different sdcard (8GB, if it matters). No issues. No idea why this worked, so I guess the mystery is unsolved.

Probably partition of your sdcard. Try reformatting it to another format like NTFS or something?

In fact, CWM can't real actual SDcard (dock slot), it read the MicroSD only (the tablet slot)
Try putting the zip at the root of the MicroSD, and launch CWM

For me it´s doing the same - can´t mount SD card. I have microSD card that I have formated into FAT/FAT32/NTFS - nothing worked. I try to put it into SD card adapter and nothing too...
Can someone tell us please, where is the problem??? I have root, flashed cwm 3.0.2.8, standart ROM...

MicroSD needs to be formated into FAT32 and only this format
If you read the post above yours, you would have also seen that the SDcard slot on the dock DOES NOT WORK in CWM

Yes, did this. I wasn't messing around with the dock, just the microSD in the tablet itself. And yes, the .zip was in the root directory--though it's not like I was able to get this far. I was not even able to see the root directory, at all.

Plug it in while android is running, and check if the MicroSD is seen in /removable/MicroSD
If, yes, that's pretty weird. If not, try another MicroSD

I had the mounting issue as well. But I formatted my micro SD card with SD Formatter (I am not allowed to post URL as a new user ), then it can be mounted.

myode is right, use SD Formatter 3.0 will fix your problem.
It use low-level format, where windows format don't.

I came across (i can't remember where exactly) some people swear that by formatting the microsd card in a android phone, the card no longer exhibit abnormal behaviour in the tf101.

[Q] Why Can't I Mount SD Card in CWM?

I tried to install the newest version of prime by micro sd card in cwm. Everytime I try to install zip from sd it says error cant mount sd card. I have installed it before without any issues. I formated sd card and tried to do again. no go. I then restarted tab to see if it was showing on tool bar and it was and showed the zip in sd. I then tried to mount in cwm and it had error again. I decided to unroot and start from scratch. still same issue in cwm. please tell me what the issue is.

This happens when your sdcard is not propperly formated. Try THIS

Format it as fat32 and everything will be alright!

I'm more inclined to believe PhatUgly on this one. I've formatted some microSD cards FAT32 and they didn't mount correctly. Did just about everything I could to remove and restore volumes, reformat, etc. Nothing worked, but it may have been a bad card. Or, it could be that there's more to it than just formatting. I'll have to try it with the SD Formatter linked in #2 above and see.

Im having similar issues as well. I got my tf for christmas (woohoo) but have had nill success with full size sd cards, and as a note I did update to the latest firmware before anything, that may be related.
Ive tried rebooting, formatting fat32 and ntfs, ive tried taking my working 32gb microsd, putting into an adapter and still wont, or any combination of things ive mentioned. I tried the above mentioned sd formatter with no luck.
Also of note, this is the sd card I got that works everywhere else but my tf:

Any other options other than RMA?

Trouble with SD Card

Hello!
I have problems with the sd card (16gb, calss 4) and ICS Roms. Under most ICS Roms (Android Revo, InsertCoin, Leedroid,...) my SD card wont be recognized. Under Gigerbread i had no problems with the same card. The recovery recognized the card also without any problem. Only HyperNonSense ICS recogniced my SD Card without any problem.
Please help me... -.-

General SD card problems
If your getting general slow SD card, issues with content on there being read, backup the importent stuff like photos etc and format SD card, seems the old android files on SD card may be messing things up. thanks orihuri for the tip.
If this didnt help and your still having prolems with slow SD card speeds download sd booster from the market and set the cache to 3000+ thanks to lws803 for the tip.

Can't copy files to the SD card

I have tried using ES file explorer, the Asus file manager, and FX file explorer. I get a copy failed message every time I try to copy a file to the removable SD card.
Anyone else have this issue?

Have you tried to reformat the card with fat32?

I just did. Seems I'm only having issues with the 32 GB size cards. Acting like they are read only. Can't find such a setting anywhere. Is there another format that should work?

Have you tried with the latest kernel (JB version .25) and what make and model of your sdcard? just wonder if compability issue and are we talking about Micro sdcard or full size sdcard? On the full size there is a little switch on the side to block writting to the card.

I'm only having issues when I'm using the tablet to copy files. I'm on CleanROM Inheritance. I don't recall if I had this issue with the stock rom. Sometime tonight I will make a backup of my current and then flash to stock rom. Since I'm talking about the removable SD card, it could only be the micro SD that is installed in the tablet. There is no switch on that card.

I think flashing the _that nodpi kernel should resolved your issue, give it a try.

download this http://d-h.st/M6j then flash with twrp, during the install pick _that_nodpi_stock kernel.

That did it. Did it replace the overclock kernal I selected when I flashed CROMI 3.2?

Yes, it replaced what ever kernel you selected during cleanrom installation. Since it stock kernel, you can no longer Overclock.

Is there another kernel that can be the fix and still give us over clock?

Sorry but nope, I believe as soon as Asus release source code, _that is going to make an OC version for this and it's going to be awsome. For now we just have to wait.

Hi.
I'm having a problem with my Samsung Micro SDXC I (Class 10) card. I've been messing abut with it for days now, formatting, re-formatting in exFAT, FAT32, NTFS but the problem persists; whenever I try to copy data across to the card, the first time the card is inserted, it starts to copy, sometimes even up to 1.5Gb of data but often much less, but then gives me a 'Write Error' or 'I/O Error' message & stops working. Sometimes it also deletes other data on the card when the error occurs. then, until I unmount the card again, it barely functions at all!
A big factor in buyinh this tablet, unlocking, then rooting it was so that I'd have an awesome, small, tablet that had loads of storage & could be transported around very easily. If I can't get the cards to work with it, that's a big part of it's usefulness to me down the drain.
I tried to download the kernal that was mentioned above the message of yours that I'm replying to but the file has been moved. Do you still have it?.......or know how I can resolve my problem without it?
Any help would be much appreciated.
Thanks.

You don't say which rom or firmware you are currently using. Without knowing that I wouldn't go blindly flashing kernels that are nearly a year old
It could be that your card is actually damaged as I can copy files just fine on mine. I'm using a SanDisk Ultra uhs-1.

Hi sbdags,
Roger that
I'm not bad with most things tecchie but whilst I know which ROM I'm using, I'm not sure what the firmware is.
I recently updated to CROMI-X 5.2.2 from an earlier version in the hope that that might include an update or something that would solve my SD card problem.......it didn't
With regard to 'Firmware', I'm not sure where that's listed on the tablet but in the 'About' tab in my settings, it says:
Android Version - 4.2.1
Kernal Version - 3.1.10-g215ae8bf [email protected] # 1
Build Number - TF700 CHROMI-X 5.2.2 - 10.6.1.27.5 WW DEODEX
Pad EC Version - PAD-EC20T-0216
MobileDock Version - DOCK-EC20N-0207
I hope the firmware information you need is in there somewhere?
The card I bought is the latest 64Gb Samsung Micro SDXC Pro UHS-1 (Class 10) with write speeds of 20Mb/s & 70Mb transfer speed. I had read the formums & was torn between this card & the SanDisk 64Gb Ultra Micro SDXC (Class 10), the two-tone red/grey version, presumably like the one you're using but the Samsung was faster & at the time I bought it, the Samsungwas almost £15 cheaper. Since they were both reported to work, I opted for the Samsung card; maybe that was a bad decision?
I've just ordered the SanDisk 64Gb card, in the hope that that one will work because as i said, it really would be a shame if I can't make use of the extended storage that the SD crads give.
Do you use your SanDisk card in Micro SD form in the tablet or SD form in the dock.....or both......& have you got them formatted to exFAT or some other format?
Thanks again for your attention.

Well the ROM is mine so you are all good there. Lol. I only use fat32 as that is how the cards come.
Are you copying the files in esfileexplorer? Are they single files? Total size?

Hi sbdags.
I've tried using both the File Explorer that was included with CHROMI-X & another one from the Play Store that I use on my phone called Astro; the same thing happens with both. As I say, the card seemed okay to begin with but all I had put on it was my Nandroid & Titanium backups (approx. 2Gb total with lots of small files included). The problems started when I tried to copy a season of a TV series onto the card to free up space on the internal SD card. It started off okay & I wasn't expecting any problems but then approx 1.5Gb, I got an I/O write error & then all the problems I described in my first post.
As an aside, the card performed best when formatted to FAT32 but according to the SD Card Association, SDXC cards come formatted as exFAT, so that's how it's currently formatted; I thought if that's how it came & it initially worked okay, maybe that would solve the issue. Again, I was wrong!
So, I'll format it back to FAT32 again but as I've already had it in that format, I wouldn't anticipate any change to the card's behaviour.
The 64Gb SanDisk card should be here in a few days, so I'll be able to report on whether that one works or not then.
Did you have to re-format yours when you first got it or are the SD Card Association talking nonsense? Oh, & you didn't say whether you're able to use your cards in both micro form in the pad &/or full-size form in the dock? Also, was the Firmware information you asked for in that mass of stuff I listed. If not, where do I find it, so I know for the next time you ask

I've never tried my card in the dock to be honest. Both my cards; 32GB and 64GB are SanDisk, I am not sure now what they cam in but I am using fat32 as I formatted them myself.
As for the stuff you posted I just wanted to know the rom and bootloader version. So CROMi-X 5.2.2 on 10.6.1.14.10 would have ben enough. Maybe the kernel helps too. In your case you are using the stock kernel. You may get better results on thatv4 kernel?

Cheers.
So, I think I've grasped that the kernel is similar to the BIOS on a PC; is that correct?
When you say that I may get better results using _that's v.4 kernel, what improvements are you thinking I might see?

Not really, the kernel is ... the kernel. The core of the operating system. Under Windows it's ntoskrnl.exe.
You could compare the bootloader with the PC BIOS - its main function (nowadays) is to start the operating system.
