I could really use a hand with this pickle

okay, so i've found myself in a bit of a pickle. Recently I've been running the CM7 nightly's, but today I tried out the RoyalGinger rom and I believe it either corrupted my SD card or it's blocking my SD card from being used/read.
Tried several times to reformat it but each time it said 'checking SD card', but the weird thing is I have an active wireless connection, but I'm not getting texts. I can download from market, get on Facebook, etc, but my texts won't come in until I reboot the phone. A few times I booted it up and it wouldn't allow me to even see my homescreen because it'd pop up with EVERY app force closing (including google services, framework, etc), I was able to get back to my homescreen by clearing by Dalvik Cache luckily, however I'm still unable to do most anything. I went in to wipe/restore but it says cannot find SD card, directory invalid, cannot mount, etc.
Is there a way to reformat my SD card through terminal? If so could I get the code procedure for it? or anyone have any ideas other than picking up a new micro (which isn't a big deal but I'm strapped on money til Friday) but i'd still prefer to know that it's JUST my SD card and not my phone memory. Anyone? Anyone? Beuler? Beuler? Thanks in advance. I'm really sorry if I posted this in the wrong section, but c'mon, everyone gets one.

Ok so do u have a stock backup rom? Ide say go to rom manager and go to recovery and whipe etc.. Then install that stock back on it.....And can ur sd card even read at all? Just get any.file manager and check your sd.

I think I have a backup rom of CM6, but not an actual android stock rom. It won't allow me because it says 'must have an SD card inserted' then it says must have clockwork mod recovery installed, which I do, the current version. Now that it says that I'm afraid to boot my phone into recovery, and I can't really tell if my SD card will read. I was able to use my file manager and the entire SD folder is blank.

ten minutes later: still boots into recovery, none of my backups are available on it. I was thinking about downloading a rom from the phone and trying that way, but I don't know if it'd save to the (apparently unreadable) SD card.

Ok try this...... Find out what recovery you use 3.0.0.5 or the normal 2.5.1.4 for froyo then download a rom thats the same recovery as the one u have on it right now...... If its the same as your cyanogenmod 6 then install that from the recovery manually!!!
if its not then download a rom that is and make sure you use a file manager to see if the download sticks in your sdcard. And if it doesnt stick then......your problem sir might be a corrupted sdcard, or a phone that cant read your sd.
Hope its not either or, so give it a shot.....
And ur supposed to have a stock backup as soon as you root and switch roms man Lol makes life easier

It sounds like he doesn't have access to his sdcard. It doesn't matter how many backups you make if that's the case...
If you happen to have a sdcard reader or a microsd usb adapter you could format it in windows, copy the files you need, and start again. Also did you try connecting to your pc and seeing if it's readable that way? You can format the card if your pc recognizes it. If you have adb set up you can push the recovery image to the phone without a sdcard. But once again without a working sdcard you won't be able to flash a new rom.

Hey guys I'm pretty sure it's just my SD card. I tried saving an image, just to test it and it says 'an SD card is required to download images.bin', so I'm HOPING it's just my SD Card, however my notifications are working properly so I can at least deal with it til friday, if it IS my SD card reader in the phone, well... I have a plan for that, however due to already technically breaking that I shouldn't go into it. Thanks to you guys for taking the time to post and if you know anything else that might help me I'd gladly accept it.

Hi, I have a reader on my laptop but not the adapter, so I can't tell and yes, you were right, I can't see any of my backups (which I have my stock, then cm6 and cm7) so I either need to find an adapter or get a new SD card. luckily I pulled all of my camera images off my phone last night when I put the new rom .zip on the phone sd, so I'm not really worried about 'losing' anything as long as I get my phone working back in proper condition.

Well that happened to me before as well.. All i did was replace sd cards lets the phone do its thing flash a different rom like CM6 or CM7 and then once replaced i got the adapter for my old sd card reformatted through windows and put it right back in and it worked.. So try that?

Ill have to. Thanks a lot guys I do appreciate any comments and suggestions and ill be picking up a new sd later thia week to fix it but can amyone recommend a good brand sd to pick up? the apparently failed one was a samsung 8gb

Hp is very good, u probably can find one with 8 gb. At best buy.. But if u want a 32 gb then thats online all day

I usually use sandisk so yeah try that?

Something similar happened to me. Your SD card likely has a bad or corrupted file. I used Win7 to copy over what I could to a folder in my PC. The Win7 automatically refused to copy over the corrupted files while carrying over everything else. In XP, your file transfer stops and you have to try again to ensure you have everything that's not corrupted transferred over.
After copying, I just went ahead and formatted the SD to FAT32, transferred everything back, installed on my phone, and voila.

Go into recovery and partition the card. You'll lose everything on it but it should be useable after that

Samsung Galaxy Young , SD problem.[Solved]

Hi, i'd like to share this piece of work that took me 2 days to figure out.
I am a fresh owner of a Samsung Galaxy Young. Very nice piece of hardware for the price, if i might say.
Since i like tuning, and shaping my computer, i started doing that on my device. Keep in mind, i own the European version of the phone(i'm italian.)
So everything started when i tried to upgrade to 2.3.6. No european firmware yet.
So i downloaded some asian version with English support and flashed through odin.
Everything was fine, except that my 8gb microsd seemed dead.
after many tries, i manage to make it up and running trough an usb micro-sd reader on an xp laptop, and seem to have solved the problem by running a very deep chkdsk.
A few days later(about a week) Dang! here we go again, the sd is dead again.
Strange thing was, that on my older phone (gt-s5230) it seemed to work just fine. So why wasn't it working on android or windows either?
There we go: somehow it seems that the sectors of my sd where corrupted in a very bad way, because once loaded the sd on linux( i used a virtualbox VM in conjunction with Gparted, but it worked fine since the controller uses a usb mass storage driver and not a mmc one.) dmesg showed me a very long list of errors from trying to read it's sectors.
This explains, by the way, why with the older phone it worked fine: it didn't care.
So gparted wasn't working, stuck on trying to read the partition table of the sd;
then i decided to try a crazy thing: a simple command line program:
dd if=/dev/sr0 of=/dev/sdb
It overwrote completely whatever remained of the bad sectors,along with the partition table and completely restored the sd to functionality; Just to be sure i formatted it in windows, fat32 FULL format(not the quick one).
Long story short, if you can't recover an sd, load it on linux, than launch this command:
dd if= (whatever file sufficiently long, say at least 400-700MBs, i used the cdrom because it was the fastest way in that occasion.) of=/dev/SDCARD (whatever device is the sd)
Then, full format under windows.
VERY IMPORTANT: if there is something that looks like /dev/SDCARD ,/dev/SDCARD1 or /dev/SDCARD2, do not put ANY number after the name of the device. we are going to do a brutal overwrite from sector zero; if you put in the number of the first partion or the second, you overwrite the partion without touching the sectors that our phones usually tries to read first, locking the sd.

Sd card issue

So out of the blue a notification pops up about the sd card being blank????? This is a fairly new card only used it a hand full of times..... Windows does not recognize it said insert card..... Only time i have seen that was with protected cards like Wp7...... Good thing i can still recover the data..... Wonder if it could have been electromagnetic waves from the solar flair..... Is this related to the sd card issue in other threads.....
Edit : Well I got it fixed had to do a low level format, reset write protect, full format with windows, then format on atrix 2 followed by transferring my backup .img..... Good thing i backup every few days..... If anyone needs the tools i used just let me know.....

What are you using to backup?

I use Roadkil's DiskImage v1.6 to backup my sd card..... Pop my sd card out when I do any changes I do not want to lose pick store image about 5 min later i am fully backed..... As for my android system I have yet to install cwm link for it is down.....

I have an 8gb card that seems to be dead. My phone don't recognize it, windows doesn't recognize it, all signs say it's toast. I'm interested in any tools you have so that I can check one more time before I just toss it. I'm sure it's done for, but sure it can't hurt to double check.

My card was like that @ first but this worked ..... First try this out http://hddguru.com/software/HDD-LLF-Low-Level-Format-Tool/ it should detect the sd card..... run the low level format it will return a bunch of errors that's ok just let it finsh ..... next you can try to format with windows if that does not work try this https://www.sdcard.org/downloads/formatter_3/eula_windows/ should get you back going.....

Nope, none of those recognized the card. I swapped some know good ones to be certain, and they showed, but not the 8gb. It was a cheapo that I don't even remember where I got it, so F-it/ lol
Thanks for the reply and the tools though, I appreciate it nonetheless.

[Q] Trying to root my Inspire 4g

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.

SD cards: exFAT Fat32 file sizes

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?

And the first thing you should do is format your card to exFAT, I really don't know how and why people uses FAT32

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.

How did you contact Sandisk, did you need to give a serial number or provide proof of purchase?

Tried the card in a reader connected to my laptop but nothing. I've emailed Sandisk support so will see what they say.
