Yesterday I inserted the old microSD card Form my previous phone into my A700 and I wanted to format it, but I could not find a way to do so in the settings menu. It is no problem to format cards in all the android phones I recently used.

Show hidden files within file explorer and delete everything by hand.
You really need to format only if the card has problems.
If it does not, then deleting files is enough.
But you are right, there is no way of formatting the card from anywhere in the tab.

It's easier to remove the card and format it with a PC or phone. The tablet did not mount it correctly because it was exFAT formatted I guess.
Has anybody tried to use an SD card with NTFS filesystem?
And maybe there is a way to format cards in the Iconia tab with some app or busybox, I will post my findings when I find some time to try.
Erstellt mit Acer Iconia A700.
There is a guide, thou a wee bit longhaired, but its a complete working guide on how to do partitioning from the device itself, using the Busybox part Fdisk.
Remember that your build of Busybox might not have everything included, eg. mkfs.vfat, mkfs.ntfs or other parts mentioned in the guide, so a full or partial update of Busybox might be needed before you can proceed.
Remember to be carefull about the exact details, as you might brick da **** if you make mistakes and partition/format a system specific mmcblk you shouldnt mess with.
Another detail to keep in mind is the Print command, for committing the actual changes, not just lining up the changes you wish for.
But check you bin/binx dir for the parts you need so you know your Busybox has them.
The guide is in the HTC Legend part of this forum right in the top, its by BlaY0 and thread is called [GUIDE] SD card partitioning for rooted phones
Dont skip checking the Requirements and other details, as you can do serious fckups if you dont.. Eg. DO BACKUP BEFORE you dig in.
And you will have to know for certain, the complete layout of the mmcblk's of your device, eg. Exact mount points so you do not mistake internal and external SD.. You are "visually" blind, compared to graphical tools where you can "see" what you do, whereby Busybox and terminal jobs is by written commands only.
And yet another edit:
You must understand that if you choose to have other partition types on your external SD, that while Android on your Acer tab might be able to read and write to those partitions, your recovery very likely will not. So if you suddenly have to flash a new Rom with update.zip to reset your setup or any other flashing from Recovery, dont expect it to work with anything but standard Fat32! Not ext not ntfs not much else but that.
So you see, from several but's, notes, eg's and warnings, do it with a visual tool on a PC unless you absolutely have to mess with commandline tools.

I am asking this again here, as my previous thread seemed to be hijacked by someone elses question!
I recently decided to root my inspire as i am no longer using it as a phone, so i thought that it would be interesting to do and fun to play around with all of the options available (i recently did the same thing on my Nook Tablet, and that was the single best decision i have made a while!). I started out researching the manual techniques to do it, but i didn't really like the high risk factor there (i really dont want to brick my phone) so i tried Ace Hack Kit. Of course, it has to download the phone from 2.3.5 to be able to work. During this process, it has me hold volume up and power twice, and every time i do that, it flashes up really quick something about holding volume up and volume down and power, but then it skips past that. Anyway, here is where my problem comes in: It says that it should reboot in to hboot, which it does, but that hboot should run a test, then prompt me to continue by pressing volume up, and then should reboot, flashing twice, and that should be the end of it. THe problem is, it does boot in to hboot, but it is just a standard hboot screen asking to recover, load bootloader, etc. When i reboot from there it just boots in to the phone as normal. I have tried 3 different SD cards, all of which work and are recognized by my PC, my other phone and my Nook tablet. I have also inserted a working sim card, just to be sure that wasnt the issue, and i still cant make it work. Does anyone have any experience with his issue, or any idea what i might be doing wrong?
Opening multiple threads on the same issue is frowned upon. Even if someone supposedly hijacked your thread. I read it and only 7 posts ,I'd call that far from hijacked.
Now at the issue on hand. As mentioned in the other thread. Its the SD card. Also their is a hack kit irc go there. Plus pasting the output would help aswell

OK, as i have stated, i have tried a new SD card (2, actually, with the same results.) as far as an output screen, there is none. Ace Hack Kit goes through the whole downgrade process, my phone gets in to hboot, but it is just a standard hboot screen, and it doesn't downgrade. When my phone restarts, it restarts like i just did a factory reset.
There is an output,copy what ever it says. There probably is something you missed
As too the SD card ,try adifferent one again. Your SD cards are corrupt and you need to find one that works with the kit
Also since your on a sense 3.0 did you do the changing of the boot img before running the kit?

by changing the of the boot img do you mean downgrading it? That is what i am trying to do. The kit is supposed to do it automatically. If that is not what you mean, please explain!
As to the output, copy thing, no, there is none of that. I have followed the instructions about 20 times. After starting the downgrade process, the phone restarts and comes up with a red triangle. At that point i am supposed to hold volume up and power, and it goes and reboots and i do the same thing again. At this point, i am told that the phone will boot into hboot and check the boot image. When it is done, i am supposed to hit volume up to confirm, and then the phone will reboot, this time in to the down graded image. That is where my problem comes in. Instead of checking the boot image, it just goes to a standard hboot screen. There are no error messages or warnings, and i have followed the instructions to the letter.
As far as the cards are concerned, the maker of the kit suggested a 2 or 4gb Sandisk series 4 or 6 SDHC card, so i bought 2 of the series 6 4gb, along with the 2 others that i already have. I also have 2 series 4 4gb and 2 series 4 2gb Sandisk cards, as well as an 8gb and 2 4gb PNY cards. All of the cards recognize in my phone and PC, and the older cards also recognize in my Nook (and were used to root and load custom roms on several other devices), i have not loaded the new cards in to any other devices besides my laptop and the phone for fear of corrupting it. So i find it difficult to believe that the cards could be the problem.
I know what the kit says. What I'm saying is In the command prompt it spits out a lot of info. For example it will say stuff about zergrush and or taco root. THATS the important stuff, this is what is used to allow the downgrade to be possible. If their a failure in the process it would state it there. That's why I keep asking for it. Don't understand your reluctance to do a simple copy and paste
The changing of the boot img is something that is different and you should read about it on attn1 site. Version 3.20 has a slightly different method

I appreciate the attempt to help (the reason why i didn't post a direct copy paste was simply as i was in no position at the time to take one, not any reluctance to ultimately do so...) In my recent attempt to provide you with a full copy paste of the process, i was able to figure out what i was doing wrong. For anyone who may have the same or similar issue: format the SD card while it is in the phone from your PC right before starting the process. Thats all it took. Even for a card that was brand new and untouched, or formatted before putting it in the phone, i couldn't get it to work, but it worked doing it that way, and i am now happily rooted and ready to install CM9!
Glad you got it figured out. Formatting the SD card in the phone is a must, since the phone puts important files on the card after formatting.

Wrong. There's no need to format the sdcard to run the Hack Kit, unless your sdcard is not in fat32 system file format. The only requirement is that your sdcard must not be corrupted to work as a goldcard. Corruption of the boot partition of the sdcard can not be solved by formatting and is produced by improper dismount of it.

I'm just speaking from experience. Every SD card I've put in my phone I had to format in the phone because it was giving me problems. After, no problems. Maybe it's just my phone. or the cards weren't FAT32.
You're last sentence is probably where most people screw it up. You can't just yank an SD card out of whatever device it's in, which I think a lot of people do. But I have fixed cards that were removed without unmounting by formatting. Maybe other parts were corrupt but not the boot partition?

As far as I am concerned the boot partition can not be restored by formatting. SDCARD should always be dismounted properly.
Just wanted to check peoples thoughts on this. Had a 32GB Sandisk card corrupt (i think) on me the other day. Woke the phone and seen the SD card icon in the task bar as if it had just mounted the SD but it had unmounted it and said that there wasn't one inserted. Have yet to try it in a PC to see what (if any) files I can recover.
The previous night I had made a nandroid backup (Philz touch), there was something not quite right with the file sizes not showing on screen but it seemed to work the second time around. Can't recall if the card was formatted as FAT32 or exFAT, but if FAT32 could one of the nandroid files caused issues if it was over 4GB? Anyway going to see what I can possibly recover and if it can be reformatted again before possibly purchasing a 16GB Samsung card here: (http://www.7dayshop.com/samsung-plus-microsdhc-uhs-1-16gb-memory-card-class-10). Dont mind the smaller size if its more reliable.

I quite highly doubt a Samsung SD card will be more reliable. Don't know what's the fuss about SanDisk corrupted but I myself or anyone in my friend/colleague circle have yet to face a problem with SanDisk!
And the first thing you should do is format your card to exFAT, I really don't know how and why people uses FAT32

This is the first problem I've had with it to be honest, had it or over a year and was using it in my HTC Sensation previously. I'm trying to remember if it was exFAT or FAT32, I remember a ROM (Google Edition S4 ROM) not being compatible with exFAT and checking mine out of curiosity, but just can't recall what it was and never flashed the ROM. I didn't reformat it coming from my Sensation so it hadn't changed in anyway.
Luckily all my photos were backed up to dropbox so nothing lost of too much importance. Need to get a microSD card reader to see if its completely borked or if files can be retrieved.
Someone will correct me if I'm wrong but I'm pretty sure that Nandriod breaks the files down smaller than 4GB if you're running on Fat32 so I doubt that'll be your problem. Mostly because the FAT32 architecture just won't accept a file that big unless the Linux kernel of Android ignores the limitations. I would HIGHLY recommend NOT restoring a nandroid backup if you think the sizes are off or if you're attempting to recover the data without and MD5 checksum. That's all sorts of bad juju.
As for Sandisk vs Samsung, I have both, I've never had a problem with either. My sammy card is in my TF201 and my Sandisk is in my I337 as it's a faster card from my benchmarks. But like I said, no problems with either.
As for data recovery, go check out Recuva, it's supposed to be pretty good especially for being free. Since I'm IT I have professional grade software for data recovery and don't have tons experience with Recuva. A couple tips about data recovery. Once you determine you want to recover data, DO NOT WRITE TO OR FORMAT THE CARD, that'll prove to make the entire process more difficult. it's going to take a good long time, at least an hour for the initial scan. Do all the work on the card from a computer and not through a connection to your phone. Anyway if you have any questions or possibly want some help shoot me a PM, I'm happy to impart my knowledge.

I thought it should break them down, it was just the /data partition that includes the apps and app cache, if it could be over 4GB stored as a .tar file would that still be broken down as such? Won't be attempting to restore the nandroid (if its even still recoverable) as I have flashed a pre-rooted stock odin firmware and its actually really smooth (maybe thats due to the sd card not being inserted). Although I seem to be having an issue flashing a custom ROM, as even after flashing the firmware via odin then trying to flash a ROM via Philz touch its still bootlooping (even with a wipe/factory reset and clean install format). Haven't attempted a different custom ROM but just havent had the time to test that out. Thinking I would have to download the original firmware files and start from scratch with rooting and adding a recovery to see if that solves it, but think I'm going to sit tight for the moment.
Thanks for the recommendation and the support, much appreciated.

Well in general in windows when a FAT32 structure is asked to write a file larger than 4GB it'll flat out deny it (usually saying something like disk is full). If you're writing to a FAT32 structure using something that increments the file as it writes it, when it hits the 4GB file size limit, it'll usually say again disk is full and the file will go corrupt (which can lead to the file being undetectable). I do believe that Nandriod is smart enough to realize when it gets to that 4GB limit it'll break the tar into multiple files or else the linux OS would probably kick back an error. As for your ROM bootloops and things like that, I'd see about another ROM, maaaaybe it could just be that the ROM you flashed doesn't like your phone (I have an i717 that does that with a ROM). If that still doesn't solve it, like you said. Start at the beginning completely clean and just work through the entire process.

Cheers, I had re-downloaded the previous version of the ROM which I was on before hand and made sure to check the md5s but it still wouldn't boot which was annoying, but a full install from scratch may be the way to go. Never had bootloops before and was just worried after I had wiped and started a fresh and it still happened. I think the real lesson is to make sure to backup ANYTHING that is of value to you!
Luckily I had just happened to use the auto backup for photos to dropbox so got off lightly this time!
I have had the EXACT same issue 2 weeks ago.
I bought 2 x 32gig microSD cards (Sandisk)
1 for my phone and 1 for my digital camera.
Recently the 32gig one in my phone just DIED for no reason at all. Lost all my files, music, everything.
I contacted Sandisk, had it repalced. In the meanwhile i purchased a 64gig Samsung one.
I am yet to have an issue with the Samsung 64gig, but only time will tell.
On a plus note, Sandisk sent me a replacement 32gig card very quickly (infact too quick, i purchased the 64gig Samsung one on the idea that the Sandisk replacement was going to take months... in fact it only took 6 days...)
Cheers
How did you contact Sandisk, did you need to give a serial number or provide proof of purchase?

I always use Fat32 on SD-cards. Why? It works on every Rom, with every kernel, every recovery, on every device, every camera, every computer, all the time.
When not in need of files greater than 4GB Fat32 simply is the way to go, compatibilty-wise.

I posted this the ROM section also but wanted to try and get some fresh eyes on this see if anyone else could come up with something.
I need to find someone who knows sdcards and how it works in Android really well. At this point I am convinced its either something in a file or permissions as to why the SDCard is not showing up in Storage.
I have two cards I can put them both in another U11 recognizes them both can format them both and neither is encrypted. I put them in this U11.
I can move stuff to them in TWRP yet I cannot mount them in TWRP and they don't show in Android.
So we know the cards are good. We know the slot is good. That leaves a file, setting or permission in Android 11 or this rom.
Minor update I'm no longer really needing a solution to this problem although it would be very helpful for everyone if one was found as I'm sure this has been a problem too many people at this point)
I'm over here trying to root my S6 Lite tablet without a computer just a bloody cell phone and I am oh so close but I have no way of reformatting this SD card cuz xxxxx Android wants to put it as FAT32 for god knows what reason it's an 8 gig SD card and I've even tried reformatting it in both devices I have same result Android just being stupid and I am at the end of my rope here cuz I have not been able to find any apps once so ever that actually allow me to reformat an SD card with a format of my choosing or at least one that's usable
Now please tell me that someone on this xxxxx website has a solution to this problem because once again the weird stuff I'm doing has led me down a path no one else has seemingly took
(And if anyone's asking why I'm rooting this tablet it's because Android 12 works like crap)
Mod Edit: Some content removed.
I am kind of stuck between a rock and a hard place as I have not been able to figure out any method of formatting this SD card with something usable because Android is for some unknown reason only formatting it with FAT32 despite using two different devices to attempt to format it normally and I have not been able to find a single application that exists that does not require root permissions that would allow me to change the format of the SD card I have legitimately spent like three or four hours now trying to figure something out and have come up with nothing please someone here help
I'm just going to add this year that I obviously don't have access to a computer or this wouldn't be a problem
Root your phone and use twrp to change filesystem.
But in your case when you don't want to root. Unplug SD card and connect with adapter to your pc.
Go to this computer and right click on the SD card
Click format And select filesystem
Quick format is fine
Format and when finished
Put SD card back.
Done

Both of those are a problem because I don't have a computer to use and I am trying to root my tablet and the only other device I have is an a20 cell phone that's not rooted either and I am so close but I can't Flash the modded firmware because Android is formatting the SD card with xxxx FAT32 so besides this SD card the only other option I have is to attempt to do the flash over wireless ADB I mean seriously if I had a bloody computer I would have been done like 3 days ago
