Nexus One Thinks All SD Cards Are Blank

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.

[Q] SD Card issues

Here's a quick breakdown. I got a 32gb SD Card (Sandisk) for Christmas. I hadn't been able to get it to work properly with my phone since then, thinking I needed a microsd reader to format it. I finally did so and have had a number of problems with it. For starters, I ended up soft bricking my phone as when i rebooted it showed that there was no safe system enabled in safestrap, and I ended up accidentlly rebooting when I didn't have an OS installed.
I FXZd the phone back and have since then been attempting to get the SD card working. All of the phone's SD and Internal memory are cut and pasted onto my PCs hard drive. Here's what keeps happening.
I attempt to copy the files from the PC to the SD card via plugging in the phone via usb. I get an error that says it cannot read the file from the PC after it attempts to transfer some of the files. I then used the MicroSD reader I have and was able to cut and paste everything over successfully. When I put the SD card in my phone, a bunch of my apps are back, terrific. Some of my key apps are not back, however, and none of the data/settings are there. I had a titanium backup file copied on the SD card along with everything else, and Titanium is finding the apps that have reappeared, but none of the ones that seem to be missing. Trying to get titanium to locate the backup folder results in the program saying theres is no backup in the folder (again despite the files being in the backup folder).
Here's wehre I really start to get agitated. Once I plug the phone into the computer with teh SD card in the phone everything works great. As soon as I uplug the phone, I get a message saying the SD card is corrupt and needs to be formatted. WHen I plug the phone back in, there are only 4 folders and a handful of files on the SD card, even though there was just 16+gigs of information on there, and now there's almost nothing. I have then reformatted the card and repeated this process several times, to the same result. The SD card seems to work fine with a portion of the data until i plug the phone into the PC, at which point the SD card tells me its corrupt again.
I have no idea why this is consistently happening, but I'm extremely frustrated that I've essentially lost most of my important data when all I wanted to do was plug in a new SD card. Any help will be greatly appreciated, I have no idea what to do from here. Thanks in advance if anyone has any advice.
Edit: the 4 file folders that remain are .android_secure, LOST.DIR, Music, and Safestrap.
As I recall, Lost.dir is what it sounds like - essentially files that get lost somehow, the entire folder is populated with 1000s of files whose names are only numbers between 1 and 217279. Only about 8gb is being used on the SD card, despite being more than 16gb being used on there before plugging in the phone and going into usb storage mode.

Okay, just to specify as a follow up - I've accepted that I'm probably going to lose all of my application data - whatever, it happens.
Regardless, I could still use a little help - essentially, every time I plug my phone into a computer, everything works fine, then when I unplug the phone (pushing the button to turn off usb mass storage), my it tells me I have a damaged Sd card and recommends I format it.
Thus far i reset the phone and its fine. Any advice on how to avoid this repeated error other than that? I'm running CM10.1 if it matters, and have heard there are some SD issues with it maybe? but haven't been able to turn up any answers on google.
Thanks in advance if anyone has any advice.

I also have a 32GB SanDisk card that intermittently gives me the "damaged" error message. It's very inconsistent, but a reboot or two always fixes it. This happens on stock ICS or CM 10.1. Wish I had an answer for both of us.

[Q] is my SD card really dead?

Hi guys, I have a 64GB SanDisk Ultra MicroSD class 10 card. I use it on my Samsung Galaxy s3. Couple of days ago I went to my friend and ask him to give me some movies. He was sending it via data cable but we got frustrated and we had to go somewhere so in the middle of transferring data he unplugged the cable and now my SDcard isn't working anymore. I mean can it be damaged just because we unplugged it in the middle of transferring? I've done it so many times before but it wasn't really a problem. Anyway I'll try to explain what I did with my card since then and what was it's response.
1. The data in the card is intact, I've backed it up as well and when I put my card into my phone it works perfectly. (btw the card was in FAT32 format)
2. I can copy stuff into my card but when I put into my phone it wouldn't show and when I put it back on card reader again the file disappears.
3. I can delete stuff from my card then I take it out and put it back again and the file that I've just deleted comes back.
4. I've tried formatting it but it would give me an error.
5. I've used Easeus partition manager but it would give me an error as well.
6. Then I've used the software I've used when I first formatted the card to FAT32. Guiformat. It would format my card normally but when I go into my card all the files are there.
7. I've tried using commands like "chkdsk d:/r or chkdsk d:/f etc but after like 44% it would say certain files are invalid and can't continue the do the checkdisk command (the file it shows was the files I tried to get from my friend)
8. I've tried so many other stuffs but none of them seems to able to format my card.
now my question to you guys is my card really dead? can it be dead just for interrupting file transfer? is there any way to get my card back to normal? anyway I can format my card? I'd really appreciate it if any of you guys can help. Thanks

I can't see the files form SD card after Android 10 update

Hello,
After the update to Android 10 I'm not able to see all the files from the microSD card. I can see them on PC but not in the phone. Also, when I'm trying to connect the phone to the PC I'm not able to see the microSD card. Any advice's to fix this issue?
Thanks.

My sd crashed completely after the android 10 update. Formatting helps 1 time after that phone dosnt detect it anymore. On pc all is fine and no bad sectors. Don't know what's happening there

My phone restarts after I introduce de PIN CODE after "Starting Android"

Hello everyone, thanks for reading this, my problem is this
I have a Motorola E5 Play Android Oreo 8.1.0 Build OPGS28.54-53-8-15
My phone was working normally, but it suddenly rebooted itself with no reason, after reboot, It asked me for the PIN as usually, but after the message "Starting Android" it tries to continue the boot, but after a few seconds it reboots, and ask me again for the PIN code.
When I remove the MicroSD card it starts normally, but my data is on the Card, and it is encrypted due to it was formatted as Internal Storage, I cannot access to my files.
I Cloned the MicroSD Card Using HDD RAW Copy Tool to a New SD Card. But the problem persist with the cloned Card.
When I insert the MicroSD Card when it starts with no MicroSD Card, it reboots itself immediately, no matter if its the Original or Cloned Card.
I tried to test if it could be the MicroSD slot, formatting the new card as internal storage, the reboot is normal, but I don't know if it is enough to know the integrity of the MicroSD slot.
I tried to reboot the phone in safe mode, when I boot the phone with no SD, and inserting the MicroSD Card, but it still keeps rebooting. I don't know if there is another way to boot in safe mode.
All those test makes me think that is a Corrupted File System, and I'm wondering if there is a solution to fix it or recover my info from the original MicroSD Card since it is encrypted and the data is inaccessible in the normal ways, please help me.
Thanks in advance.
