When I press gallery it says my SD card is unmounted. I powered off, removed card, cleaned card and phone, then I restarted it and it worked but now I'm getting it again. Pretty annoying. Also, is this the type of issue covered by the warranty?
I ran a search on Google and nexus one general forum before posting, thanks in advance for any help...
oh wow....i just unmounted the card, then i powered down. when i powered on it said the card was damaged and i may need to reformat it.
So i put it in my laptop and it says it needs to be formatted.
Have i lost all of the stuff on my card and, if so, what could have caused this? its kind of devastating for me.
The ONLY thing i did today that was out of the ordinary was install zumodrive on the phone.
its a class 6, A Data 8 gig and ive had it for a matter of 6 months, im guessing it was the phone or an app that caused it?
Unless you were constantly removing the card while a device was in the middle of writing to it, I dont think the phone it self would have caused much damage... I'm thinking it was more likely a defective card...

bummer, so i probably should just trash it as opposed to formatting it and using it again?
i have had a card fail on me, and was able to get it back and it worked fine. seemed to be just a tad bit slower the second time around, but nonetheless it worked.
it was weird thought, windows wouldnt detect it, and my phone wouldnt either. i had to go into drive management and it was seen there. once i got that squared away and go tit formatted all worked well.
as far as saving your files, im not sure... i try to backup my sdcard about once a week (simply overwrite any files that havent changed). you may be able to use a disk recovery utility, such as the ones that are used to retrieve files from dead HDD's.
i had this problem on stock
i ended up putting my sd card in the pc and backing everything up (everything was fine even after the phone showed it was corrupted)
reformatted my sdcard
tested and still got the error
so i pulled the sdcard back out, started the phone up without any sdcard inserted. after putting card back in and booting up never had the problem again
since rooting, i've never run into this problem either
Hi, I recently purchased a Dell Venue Pro and I am going to get it some time this weekend. The main concern I have with this phone is the small amount of storage. 8gb is simply not enough for me. Perhaps I missed something, but I've been reading through this forum and haven't found a very good explanation for newbies on how to replace the SD Card. I have actually seen some posts that say that they managed to exchange their 8gb SD Card for a Sandisk 32GB micro SD card Class 2. However, I would like to have some guidance and instruction from someone experienced doing this; I wouldn't want a bricked Dell Venue Pro.
Therefore, could anyone please instruct me with a step by step guide on how to replace my SD card without crashing my system and which sd cards are compatible? Thank you.
Believe me when I tell you this will not work. What you will end up with is a bricked phone that needs to be replaced.
If you have a device that was shipped between December and now you don't have an engineering sample, those are the only devices that can actually format the sd card to the proper filesystem and lock the card down in way you'd expect it to.
If you'd like to test that theory, simply replace the card while it's off. Perform a hard reset on the device (the CAM + VOL DN combination does not work), shut it down and put the card back in an SD reader. It won't be formatted and won't be locked down.
You might be able to format the card on a Windows CE machine with storage manager, but the most I've been able to do is get the SD card test to show a 114 not ok instead of a 115 not ok.
After that, if you're lucky, you'll be able to simply throw the old card back in the device and proceed with enjoying your phone with the original SD card. If you're unlucky your phone will not boot.
Food for thought:
In the diagnostics application there is a button for "Service Center" which displays two boxes: Zune and Composite.
When you press the CAM key during boot this puts the device into a "restore" mode that Zune is supposed to work with at some point in the future.
I'm guessing if we can figure out a way to flip the mode to Composite (currently requires a password) that the "test/debug" bootloader will allow us to format the cards properly.
It's also entirely possible that the reason the engineering samples work and the retail devices don't is that the eng samples are in this mode already.
Wow thanks a lot for the very thorough answer. Do you think we will see memory expansion as a possibility in the near future?
Ok, without trying to insult anyone, 'm gonna call Bullshxt. I now have 3 VP's in my possession. Ok....1 I dropped and it doesn't start any more. But that still leaves 2. On both of them I have removed the SD card, replaced hte card with bigger and smaller SD cards and have even left the SD card slot empty. I have NEVER bricked my phone.
Let's leave performance behind first...and not consider it. Lets just talk about changing cards.
The key to changing cards is process. Take the card out and restart your device, it won't boot. there is no external keys for hard reset. Place that same card back in your device, it will start.
To change out a card, do this:
1. Hard reset your device
2. On the reboot portion, remove the battery and then remove the card
3. Put the battery back in and let the device start up
4. Walk through startup and your phone is ready to use.
Keep this same process each time. You cannot remove a card, without first going through the hard reset process. You cannot add a card with out first going through the hard reset process. The hard reset process initializes the card to the device.
I've done this at least a dozen times, with cards ranging from 2,4, 8 and 16g. I've done it with cards pulled out of Google phones and an HD2. I've done it with cards that have never been used before. Its 1, 2, 3, 4. No matter what combination of removal and add....1,2, 3, 4. Remove a card, its 1,2 ,3, 4. Add a card, 1,2,3,4. Simple.
Now...if you want to talk about Performance....thats another conversation....
Again....no insult intended with the BS call.
Sorry...forgot to add 1 thing.....this has been described on this forum several weeks ago...so...what I'm saying is not a huge discovery from me...but rather from the guy that posted this around christmas.....I just repeated it is all !!!
Oh OK, sweet thanks for the thorough step by step guide! This is exactly what I needed.
A few questions though.
On step 2. you mention a reboot portion. What does that mean? After hard resetting what is my "queue" to remomving my battery and SD Card
Also, you never state in the 4 step process when exactly I put my alternative SD Card in. Would I put it in step 3 when I put my battery in?
Finally, you say Performance is a different story. Are you saying that replacing SD Cards will make the phone slower or more prone to crashing or working less stably?
Thank you.
I think once the phone is ready to use again, you then start the process over again at Step 1, except instead of removing the SD card in Step 2, you put the new one in.
What I want to know is, if taking out the provided SD card voids the warranty, how do you get a new phone without paying for it? Or does the warranty not cover that specification?
none taken, but your claim about the device not booting if you remove the card is false.
It will boot, sans card, with ~15mb of free storage space with no customizations. It's also likely though that if your device does boot into this state, you will never be able to get another SD card to work in it ever again.
Even if it boots into the "no storage" state it's still possible to put in the old card (in most cases) and have it work. I'm just saying that has not been the case for everyone.
Looks like I've found quite a good amount of posts from people stating that they have swapped SD cards succcessfully so might try this if I feel like I require more storage. Would anyone happen to know if there are certain types of SD Cards I should use to make this work? Also, alodar1, you have stated something about performance being another story? Would I be sacrificing performance by swapping cards? What kinds of issues would I be having?
1) Open settings-> about menu in phone
2) Press "reset"
3) Press "yes" twice. The phone will start to reboot.
4) Wait until the phone shuts down and begins to reboot, and take the battery out. NOTE: If you take out the battery too early, it will not work correctly. I waited until I first saw the Dell logo pop up and then pulled the battery, and that worked.
5) Remove the old SD card (I used a very small eyeglass screwdriver to gently pry it out since it isn't spring loaded)
6) Put in new card, replace battery, restart phone
7) Go through the setup process
That should do it. My phone hasn't crashed since I replaced the card on Sunday, so its been a success for me. I have not had any performance issues with my new card - but I suppose that really depends on your card. Granted, I actually downgraded - I went to a Sandisk Class 4 8GB card. Soon enough I'll be getting a 32GB card and trying that one out.
Ah things are much clearer now thank you very much, will try this. I'll pray my phone doesn't go bad... gulp.
Also, are you saying you were a victim of the crashes and replacing the SD Card fixed it?
OK so I'm going to buy an SD Card, a 16gb, so should I go for a class 2 or class 4? What's the difference between the two and is any one of those two incompatible with the venue pro?

Yes - my phone crashed very frequently with the 16GB card. Many times a day. I've now gone a full week without a crash with the new card.

Mine is class 4. The problem here is that there is no official specification. The class rating refers to data transfer speed - but the requirement for Windows Phone 7 is random access speed, which the card manufacturers don't advertise. Early reports actually showed that higher class (6+ cards) actually perform worse in WP7.
I don't have the DVP yet. Will the warranty be void when the SD card is replaced/removed? Thanks.

Yes, the black tape shows "VOID" after you remove it. A prior warning would be nice, since the tape doesn't say that on the outside.

Does it really say "VOID"? I removed the tape but I can't discern any letters left on the device. However, I can see an "O" on the tape.
yep, it says VOID and the black VOID letters are left behind when you remove the sticker.
So for those who have replaced their cards, how is the phone holding up? Able to use wifi and the marketplace and IE with no crashes?

sorry for the delay in replying. No, not necessarily. Personally I believe there is an issue with the specific cards Dell used. But what do I know for sure. I swapped to another 16g card...nothing fancy...just directly out of the HD2.....it worked and performance was better. A couple of friends of mine did a similar swap, looking at specific R/W speeds, class types, etc. They had mixed results. So, my guess is, there is something else that is a trigger that no one has hit on yet. I know my 16g performance is not as good as the 8g performance....in smoothness of card access. If I swap down to an 8g card...or even a 4g card....I can see the difference.....the performance is smoother.
Now, this doesn't say that those people with the 32g cards are NOT seeing that smoothness. I'm saying that I tried this as a test because I had cards laying around....and noticed a difference. The difference strongly indicates the shipped 16g cards are not what they should be. But, this does not mean the 32g cards on the market right now are the answer.
HELP !!!
I tried changing my 8GB SD card to a 16GB SD card. it booted up fine everything seemed ok, but when I restart the phone it loses all settings. So I put the original card back in, followed the same steps. Now my phone only sees 16 MEGABYTES of storage, I've tried multiple factory resets, after a reset it doesnt even go through the normal setup process. All it does is go back to the homescreen with only the normal tiles accept all the newsroom, tmobile family room and stuff isn't there either. If I pin an app to the start screen then restart the phone the pinned app is gone from the start up screen can someone PLEASE help, I'd be happy just to get it back to normal, with the original SD card in it
This is the second time and a different card that this has happened with me. I've tried ruu and that doesn't help. I thought maybe there was a file on it that the phone didn't like so I backed up the card and let the phone format it. Problem went away for awhile. I got a faster card and now its doing it again. I had a similar but more destructive times of this happening with the evo. It would corrupt the card and I lost everything on it. What I ended up doing was put a piece of paper the size of the card on top of the card. This was to make the battery hold down the card more firmly. I suspected the crappy mechanism htc used on both phones is at fault. The card would wiggle around when it was seated in the slot and the lock bar down. I don't know if this is the case again with the shift but I did it again with this card. Hopefully that does the trick. I would hate to take the phone back.

no problems here (yet), but I hope this doesn't happen.
This has happened to me on all my android phones. My hero, optimus s, epic and now the shift. Usually just messing with it will fix the issue no problem. Pull the card reboot etc. Worse come to worse back your card up and reformat. That fixed it for me before.

Have any theories on why this happens?
I haven't had this problem but my Moment would occasionally tell me the SD card was damaged when I knew it wasn't. Figured out that just plugging it into the PC and having Windows scan the drive for errors would fix the problem. Maybe it might work for this too...?
I'm guessing that the SD card doesn't sit in the card slot and recessed area very well. Sometimes, over time, the card might be jostled by handling of the phone like if it gets bumped. The contacts lose a solid connection with the other half of the contacts inside the phone and an error happens. In some cases with some phones, I speculate when a card shift happens during a write cycle to it, the file allocation table doesn't get updated correctly, thus temporarily corrupting the card. Seems as if a format fixes it sometimes. That's my guess. When I put a piece of thick paper, less than a millimeter in thickness, on top of the card, and the paper is the same shape of the card, and the weight of the battery on it helps keep the card from having the tendency to move around in the card socket. The errors don't seem to happen again for me.
Why does this crap happen to me? The spring loaded card sockets on phones, I've never had this problem. They seem to hold the card in place very well. It's probably a cost issue because a plastic bar to hold the card down is cheaper than the metal spring loaded locking card mechanism.
It happened again. It seemed to happen when I tried to open a file. It seems like it only happened when I messed with the file. I deleted it and so far so good. It seems weird that a file would make the card go into read only mode.
I had it happen once. It was when I was disconnecting from the computer.
I always eject from computer, then select charge only before disconnecting. I read that on an EVO forum

I managed to have this happen on my Hero with an 8GB class 2 card. I returned it and upgraded to a class 6. Also I made sure to always properly eject the USB in Windows after that. Not a problem since. Knock on wood.

it happened rarely on my Moment but not on the Evo Shift . usually a reboot cleared this problem for my phone

Yup, this works great
It's happened to me before, but on my Hero. Haven't had it happen on my Evo Shift yet.
Only thing that's happened is one time I had my phone set as a disk drive when connected to my PC. A friend of mine called me and it couldn't read the ringtone from the SD card, and I got an error regarding DRM not being installed. Once I disconnected the phone from the PC, everything worked just fine.
.......right in the middle of a super demanding day, the message "damaged SD Card / Reformat" appeared on my Epic, when I least expected it (inopportune is the word)............ changing firmware is never without its more interesting moments, + this may or may not be a symptom (went froyo to gingerbread), however,........... am sharing this post to the Epic community, as i sense this to be an important enough issue...........no one really knows the specific cause of sd card corruption + failure: it's variable + always somewhat circumstantial (ie, saw it mentioned elsewhere that overheating from an overclocked cpu could cause damage as well)...................so, moving forward I simply want to contribute as a brief description, here, how i was able to recover (most) of the files from my 'damaged micro sd card:'
First, when i saw 'damaged sd card / format card' on the phone, when it became possible 4 me to do so many hours later, instead of 'formatting' I replaced the damaged card for a new one (pny 16gb sdhc class 10)...booted the phone everything was fine (15.91gb space available)........as expected, no files in the SD Card......................next:
(1) placed 'damaged' sd card into the reader that came w/ the device, and mounted to pc, selected the drive (followed by confirmation beep 'device detected' sound, then the language: 'd:\ not accessible. The file or directory is corrupted and unreadable' came on the screen..........went to RUN and typed CMD........from new window, I typed Chkdsk d: /r and the PC began reading the contents of the damaged SD card (most of the android zip files etcetera were there, as were a number of files w/ no content) + next i typed 'exit' (no quotations, just the letters) to return to the windows desktop.......OK, so now the only files missing are the pix + video mov's (far as I can remember).
..........(2) next, to recover pix + video, from the pc desktop i opened ZARecovery (if you do not already have it go to Data Recovery Software, Solutions, Tutorials, Forum - ZAR Data Recovery and download the free recovery program from that site).
.............(3) from the ZARrecovery main page, selected sd card as device, selected 'next', selected 'root' folder for all files that ZAR was able to detect as recoverable, entered destination folder name (for transfer of recovered pix + video to PC....note: NEVER to sd card itself!), + lastly, selected 'start copying selected files'.........and that was it, closed ZAR + began viewing the content of the recovery folder to get an assessment of what had actually been recovered, and what had been lost.................fortunately 4 me, the loss was minimal, as I tend to create backups (Nandroids, every half year; pic, videos, email attachments = pretty regularly).
Hope this helps those of you that have been experiencing microSD Card damage (from whatever source).
Remember, + not to speak to the Choir, but can not to overstate this: BACKUP............. BACKUP............. BACKUP.............BACKUP

I am so paranoid about sd crashes and corruption because I have had my share when upgrading to the next bigger card (had a 2,4,8,16, and now 32gb in each epic) that I sync my epic cards to my PC on two separate drives for both my wife and myself (my PC has three physical (not virtual)l hard drives C, D, E) every 3 to 4 weeks. So for her, I am pretty safe except for those long updates in between her trips home. I feel pretty safe in case I do something stupid, which I do from time to time.
I actually tried to convince her to get an iPhone, because I think there would be less updates than Android, but she won't give up the physical KB. Not that I don't like updates, but I set her epic to be a 98% clone of mine, so we each have a lot of apps and each app is eventually updated and often!

Gr8 backup regimen..........'best practices' worthy.........given the 1,000 cumulative hrs leading to your perfect setup, worth all the special handling to keep devices singing!
props on the recovery
Mine took a dump today but it may be a total failure. I just got home and this is what the preliminary tests show. I would appreciate any input.
chkdsk
The type of the file system is RAW.
CHKDSK is not available for RAW drives.
testdisk
Capacity incorrectly showed at 8225kb/8032kb (16gb card)

As a sidenote, the TitaniumBackup sync-to-Dropbox feature has probably saved my butt as far as apps/data goes. I highly suggest using it to protect against dead cards.
Sadly SD cards and USB sticks are very unreliable when it comes to data. They are easily damage and anything slight can cause them to be corrupted.
This is a great guide, glad you were able to restore your data!
Most data in flash type memory cards (excepting physical cracks in the microSD Card housing + damage to the memory chip itself) can be recovered w/ several DIY software programs available on the android market..........ugothkd shared a few of these, several posts up.........in the event that there is NO BACKUP available to you + having exhausted all personal DIY recovery avenues, there are still ways to step-up the process and very likely recover some of your data..........am quoting the following language from Recoverfab (maker of enterprise flash readers to the trade):
'In general, there are two reasons why the data on memory flash devices (cards, USB-sticks, SSD) becomes inaccessible.
Logical damage prevents access to the data/pictures on the drive, but the drive is still physically recognized by the computer operating system. In this case some specialized types of recovery software can help. Sometimes free recovery tools like Zero Assumption Recovery can also solve this problem.
Physical damage causes the drive to be unrecognized by the computer's operating system, making it impossible to access the contents of the flash-memory chip. This type of damage happens in more than 80% of all known cases. These are most frequently caused by electrical problems that lead to physical damage. Flash devices consist of a memory chip and a controller. The controller writes and reads the data from the memory chip. In most cases, recovery is possible from a flash device with a damaged controller and mostly undamaged memory chips.
Formatting is required? The controller of the memory card is not in the position to inform the PC operating system about the characteristics of the memory card. Therefore, the PC assumes that the memory card is not formatted and requests formatting. One might think that the memory card problems would be solved by formatting, but unfortunately it does not work due to the damaged controller. Instead, the computer will communicate that formatting is not possible. Such an error is a clear indicator that no kind of software (including special formatting or rescue software!!) will be able to access the memory card.
.....Recovery Process: If the flash storage device is not recognized in the computer or it is impossible to access the data on it, there is only one way to get the data: unsolder the memory chip from the printed circuit board and directly access the raw data with a programmable chip reader.' <end quote>
OK......that was a long quote!.....worth repeating, if only to begin to address the sort of things that can damage / corrupt SD Cards (+ also to give those of you that really want to recover your lost data super badly some HOPE).
Heat, liquid, dust, some of the things that WILL damage your SD Card (numerous other things can corrupt your data as well) .....then you hear cases of individuals that have NEVER HAD ANY DAMAGE WHATSOEVER...........some burnin' Q's: is the fragile nature of the card itself doomed to failure? ...If the card is going to fail eventually, what kind of data would you be willing to risk storing in there?...... if the data is that important to you, would you be willing to make a 'twin' copy?

Most data in flash type memory cards............. if the data is that important to you, would you be willing to make a 'twin' copy?

Yup, I have a spare twin identical card Lexar 32gb class 10 waiting in the wings as a backup.
I use a program that can transfer and/or sync in many different ways my card to my PC, which I do every three or four weeks. It is called FolderMatch v3.44. I am sure there is a newer version out, but the one I have does the job
I simply plug my USB cable into my PC and the other end into my epic and simply choose synchronize, then chose make left folder (my PC) to be the same as the right folder (my epic) - depending on how many files you are syncing determines the speed of the sync. Works good for me!

Mine took a dump today but it may be a total failure. I just got home and this is what the preliminary tests show. I would appreciate any input.
chkdsk
The type of the file system is RAW.
CHKDSK is not available for RAW drives.
testdisk
Capacity incorrectly showed at 8225kb/8032kb (16gb card)
Analyze feature reports a Partition Rear Error
As a sidenote, the TitaniumBackup sync-to-Dropbox feature has probably saved my butt as far as apps/data goes. I highly suggest using it to protect against dead cards.

ZAR has an 'unformat' option for Raw File Systems, you may want to explore if there is data remaining in your SD Card that you may want to recover (there's a brief tutorial posted on their website) ........ here's a glimpse:
"Unformat is the process of data recovery from a storage device (which can be a hard drive, a camera memory card, an USB pen drive) that was formatted.
The step-by-step tutorial below describes the procedure to recover data when the drive was accidentally formatted and you want to unformat the drive Windows reports "raw filesystem", or the drive is "not formatted" <end quote>
The above makes reference to a specific type of recovery (accidental format of a drive, as an example), but the application will recover from a number of file types + systems............worth checking it out.
*edit* as another example, 'accidental format of a drive' can also refer to split-second decisions we make when we guickly hit 'reformat sd card' on our device the very first time we ever encounter a 'corrupted external card / reformat?' type of message........in the moment, life goes on + it's only later that we begin to think of the lost data..................however, chances are pretty good that the data is recoverable (files are still inside the 'reformatted' sd card, only unreadable, ie RAW).
V20 H918 10j (still on Nougat)
Here's when it happened:
We were going on a road trip so I shut the phone off, took out the SD card (64 gig Sandisk), then the sim card, put the SD card back in and closed up the phone. I did not turn the phone back on. Then put the sim card in my tablet so it would have data. That worked fine.
The next day, I want the sim card back in my phone, so I do the reverse. Boot up the phone and it does not see the SD card at all. I put the SD card in the tablet and the tablet sees it just fine. Back in the phone - no go. I try a couple reboots and nothing. Boot to TWRP, it doesn't see it.
I get home and dirty flash the rom (Ovrdrive). Still doesn't see the card. I try a couple other cards (32 and 64 gig sandisk) which work just fine in other devices and the computer and the phone either doesn't see the cards or it says they are corrupt. So I format a 32 gig card (I did it a couple times in both xfat and fat32), put it in the phone and the phone says it is corrupt and needs to be formatted. So I select format. The format box is immediately at 20% and then it crashes.
I tried using ES File Explorer on the phone to format it but still a no go. I re-flashed the kernel that I have been using for the last year, that didn't help either. I used contact cleaner spray and then even used a soft small paint brush to try and clean the contacts. Nothing.
I had not put any new apps or made any changes to the phone in over a month before this happened. So.... I think somehow the pins for the card somehow got damaged or just old and something just got bent or broken or tweeked. I have another V20 that got water damaged and I looked closely at the SD card pins and compared to the current phone. I can't see any difference.
I'm posting this in case anyone else has had this problem and 1. was able to resolve it or 2. replaced the sim reader and that fixed it. Sim readers on ebay are cheap, but they have to be soldered in. Something that small is beyond my skill level.
There is a thread for the G6 that talks about this same problem. No solution. Speculation about having the card reader replaced. One person did a complete factory reset twice and that didn't work. So I'm left to believe this is a hardware issue.
Cheers.
