Nexus One Thinks All SD Cards Are Blank - Nexus One Q&A, Help & Troubleshooting

I'm having a weird problem with a Nexus One. It had a 2GB microSD card in it that seemed to go corrupt (all the file names went crazy) so I reformatted it and it happened again within minutes. So today I bought a new 8GB microSD card and and the Nexus now gives the error of "Blank SD Card - SD card blank or has unsupported filesystem." It is unable to format the card, but it doesn't give an error. I tried formatting the card to FAT32 on my computer, still the phone thinks it is blank/unsupported.
I'm hoping the SD slot isn't fried... any thoughts?

You could try reformating the SD card in a computer using SDformater with erase on.

I have the same problem for a few weeks now. My phone can't seem to read the sd card at all. Thought it was the sd card so I bought a new one, but problem remains. I know both cards work (have tested them in another phone and the computer reads them). I've tried formatting the card in the phone and reformatting with erase on using SDFormatter in my computer but my phone refuses to read it. Think it might be my sd slot as well...
Currently running CM 7.1.0. Haven't tried a factory reset or flashing another ROM (how would one go about doing that with no sd card?) as I'm not too keen to lose that data if I can help it.
Did you manage to fix it?

I was not able to fix it and after many hours of troubleshooting, so I gave up. Good luck to you, and please reply if you find a solution.

TYTN2 micros sd card not recognised

Help,
After i flashed my KAISER i have a problem. The sd card is not recognised anymore. Is there a solution for this problem?
I hope so, otherwise i have a brick
Storage card problem
I always used a 4 gig card, just tried an 512 mb card, and that one was recognised. Strange isn't it?
First, which method did you use to flash your new ROM?
If you used the USB method to flash your new ROM, did you remove your SD card during the flash process?
If you used the SD card method to flash your new ROM, did you do a hard reset with your SD card inserted?
Second, do you have an SD card reader for your computer? I would probably try to verify that the file system and data are intact on your SD card. If you have an SD card reader, you can also use it to reformat your card.
If none of this is helpful, provide some more information to fill in the gap between your microSD card working properly and not showing up on your phone.
Re
I flashed to TPCV5.1 full today. No sd in my phone.
My cars reader in the computer doesn't recognise the sd card either.
Strange thing is , when i use an other 4 gig sd card, the phone still doesn't recognise it, my card reader on my computer does, so why not on my phone.
I had a 2 gig sd card, and put all the data again on it, and it's working.
Stilli have a problem that my phone won't recognise a 4 gig sd card.
So far my story.
Does seem odd. What file system is your 4GB card formatted with? If it shows up as "RAW" or anything, I would definately format it to FAT32.
Edit: I was referring to your "other" 4GB card. I don't think I have any advice for the original one.

I keep getting damaged SD card error on my phone

On my computer it's fine. I just want to listen to my music. Damaged or not.
What causes Damaged SD cards?
Try to reformat it and see if it works. There are several things that can cause a card to go bad.
I have and just spent countless hours getting music on the card and I downloaded an .apk when I got error (Installed and worked fine) then just got error.
How to safe me from these from happening again?

Just do what you always prolly do. Just make sure to unmount before you disconnect. Sometimes the cards can just go bad. Just make sure to get a name brand card and get a class 6 (you don't have to). It was prolly just a fluke.
Sandisk 8gb class 2 I do unmount error for past 3 months. Know I can't get back my apps2sd to rework after I did a format.
How did you format it? In the phone from UI? If so then it erased your ext partition.
Look in HERE for good guide on how to check what partitions do you have and to format and repartition.
Good luck
If your running swapper, you need to turn it off before mounting. Thats the main cause if its not actually damaged.
I had that happen to me when I tried using Apps 2 SD 2. It said it corrupted my SD, and when ever I tried to unmount from the PC, it would freeze up. I just backed it up, deleted all my partitions, reformated and made new ones. What ever A2SD you're using, make sure you follow tuts correctly.
If you use AppsToSD to partition your card and you get an error saying that your SD card is corrupted or damaged, ignore it. Take out the card, format the Fat32 partition on your PC (a full format, not quick erase). When it's done, both the Fat32 and ext2 partitions will be there. I have experienced that problem several times.
Also, you can do adb to get the files off the ext2 partition before you use the phone to remove the partition and re-format the card.
Well guess what all I did was turn off my phone overnight and charge it. This morning turned back on got the same good message after spending 5 hours putting music onto my card. So this time I am doing a full format of the card and just using fat32 nothing more no apps2sd I think that may be my problem. Cause when using it I don't get the option to safe remove the sd card in SD card settings.
My 2-yr old 8gig Sandisk Class 2 SDHC suddenly went kaput and won't be detected by my Topaz.
This sd card has been previously fat32-formatted and worked for 2 yrs.
Lately, before flashing a cooked ROM, I ran the mtty1.42 if that matters
Now, my phone won't even detect another sdhc (4gig Sandisk, Class 6) which is working fine on my wife's Raphael and/or my PC.
The error message the defunct 8gig SD card gives when connected via card reader to my XP sp2 machine is:
Exception Processing Message c0000013
Parameters 75b6bf7c 4 75b6bf7 c 75b6bf7c

You can't format something that is undetected, right? Any clue, please? Thanks.

Yea that happens my 1yr 8Gb class 6 dies a while ago but that was from my using it for readyboost and eboostr(unrelated).Now i got this 4gb class 2 thats pretty fast If you had swapper then i think the card could be damaged, try formatting that sd card in recovery mode.
there is a way to reformat the card if its not physically damaged but it seems like yours is. I dont rmr the commands to do it in gparted, butits possible

How can i format it. when i try to phone just sits there and then locks up and shuts off. have to pull battery and restart.

I had a similar issue with a 1 year old 16GB card last week. Card was destroyed and I couldn't get anything off of it. The MBR was damaged and wouldn't be re-written. Had to go get a new card :-/

Problem with Micro sd card

I have AT&T Tilt with Sakajati's HyperDragon IV Windows Mobile 6.1 OS ROM, I also have this 8 GB micro SD card, which has around 3.5 GB of data, but for some reason I am not able to write on it any more. When ever I tried to format it I get this message which says " The card is write protected" I don't remember putting any password or anything. I can read data from that card on any computer or phone, but can write anymore data on the card. I can't delete anything from the card either.
Can someone suggest what could be wrong with the card and how can I unlock it?
I have tried low level format also, the format completes without any error, but when see in file explorer all the files are still there. If I try to format from SD formatter, I get error "The memory card is write protected", windows format doesn't give any error, just runs and in the end says "Windows can't comeplte the format". Card is working file and have no problem in reading the data it has, just can't write new one ot delete old one.
This is very weird problem... any help/comment is good.
Not sure if this will help....
I've had very similar issues over time...
Because of high TomTom & Music Use.
Both are loaded and work off my SD Card (6 GB worth)
What I finally found that worked for me, was to get a 2nd card and backing up my SD card to my Desktop PC, so later I could transfer to the 2nd SD Card when needed.
Then I do a Complete Format [Full FAT32 Format] of the old SD Card, via the Mini SD adapter on my Desktop PC.
I found that formating within the phone doesn't always work...
If this is not the case I can think of 2 other reasons for potential problems..
~Some ROM's require the removal of SIM & SD Cards when installing?
~If you were using an adapter formating the SD Card and it was not set to write mode?
Best of Luck!
JAC,
Thanks for your reply, but I have already tried FAT32 formatting using micro sd card, but as I said before, but it errored out.I even tried low level format, but didn't work. There is no locking swithc or anythign in micro SD card, not sure how the data can be locked. If it was ecrypted I was not able to read data on other devices. So what happened? Any help!!!
Like everything else, sometimes things just wear out, break or are just low quality to begin with. If you can read it on other devices, then transfer it and get a new card.
There is also a trick used by nefarious suppliers that takes a 4GB (or any size chip) and format it in a way that it appears as a larger chip. Then when you go to write to it the whole thing goes crazy.
This is why I recommend using reputable resellers and buying good quality Name Brand Chips, Like Sandisk or Kingston.

[Q] SD Card Problem

Recently my SD card became "damaged" or so the Android OS told me. I have a AData Class 6 16gb MicroSDHC card. When it gave me the initial message I attempted to "format" the card, yet it simply "pretended" to format it and then try to mount it again, where it said it was damaged. I tried to wipe the SD card, then i tried to wipe my phone, and neither of those seemed to fix it.
I spoke with a friend in the XDA IRC channel and he showed me an article saying that its possibly related to a bad boot, where i had no battery and tried to boot my device resulting in a fried SD card. This seemed likely, but then when i tried to use ANOTHER SD Card (2GB Sandisk) this one had the same issues.
Both of the SD cards work in my laptop card reader, so I no longer believe it to be a Card issue, and more a phone issue. I was able to boot into recovery and partition the SD cards, or so it said it partitioned. And then i was able to put the SD card into my computer after partitioning, putting some files on it, and then wiping it in recovery mode. All with the card still "functioning" but as soon as I boot into Android it says that the card is damaged, and the card no longer functions on my computer and I have to reformat it.
Is this a hardware issue with my G1? Or a software issue? All of the articles I have read about related problems say that it is a bad card, Which is why I am confused that a new card does not work as well.

Umm I think its a rom issue personally. Have you tried to wipe and reflash a different rom and try it? Or even reflash the same rom after a fresh wipe. Leave sd card formatted on fat 32 let the rom boot. Let it settle down. Then if everything seems ok. Then part sd. The reason why I'm saying this first is because I've had issues like this before. But at least try this so you can start to try and cancel things out.
