SD card format auto-eject?

I have a plain "vanilla" version of cupcake and i would like to get rosie, but i have to root my G1. The only problem is when i try to format my SD card, it automatically dismounts, or ejects it from my computer, then i mount it and try it again... and the process continues, so i came here. Anyone had this problem and/or know how to fix it?
yeah thats happening to mine right now too
but my sd card is mucked up i think
Do you have a sdcard reader and an adapter for your micro sd
if so you can plug it in and do the same process plus its more safer to do it that way
no, sadly, I do not have an SD card reader. But I am about to buy an 8GB SDHC card with a reader, so I should be able to root soon .
I know this is an old thread but I'm trying to go through the formatting process and am getting the same issue; the card automatically dismounts when I right click and select Format. I'm trying to downgrade and I found the DREAIMG.nbh file to use but when I try to run it without formatting, it's unsuccessful. Any ideas of what I could try?

Ok i finally updated..

I gave up on trying to update from my rooted .57 so here i am...
I flashed back to the factory settings and now am updating all the way to .83 unrooted.
I am now on a clean slate on .83 with no root and none of my apps or anything.
I do not have a SD card just the internal memory.
Can i still root it without one now? or do i need to go buy a sd card to get it done? last time i used gladroot without one but i dont see an update for .83 thanks alot anyone for helping.
I did the same thing and installed GingerBreak to root my atrix. It does require an SD card though and it may format it too so back up anything important you have on there.

Thanks for the response. Did you have a SD card that you put in? or just the memory on the phone itself? Because i havnt bought one yet for my atrix. Let me know when ya can. If you did it without one? how can i do it? thanks
The instructions say to have an SD card and it will format any data on the SD card. I had an extra blank one laying around so i just stuck that in there during the root process.
will this affect the internal SD card? I want to update to 8.3 and keep root, if i cant then i'll flash sbf. I have spare SD card but also have loads of files on internal that i dont want to format
You can always copy your files from internal to an SD card or to your computer.

SD card suddenly no good??

Hey all, I'm hoping somebody can help me. I'm currently running a rooted stock S5 I have safestrap installed and towel root.
All of a sudden this morning when I open to my gallery and pressed on a picture, it would not get bigger. I didn't think anything of it so I rebooted my phone. And when it came back up there was nothing on the SD card, all of my pictures and my music has disappeared. I unmount the SD card pulled it out rebooted we mounted SD card and I got an error message saying that the SD card was blank or the files are not supported. Has anyone come across this before?
When I got home from work, I pulled the SD card out put it in a card reader and on my computer again there were no files at all on the card. I put the card back in the phone and tried to reformat it, it would not reformat. I tried with several different SD cards and I'm getting the same error message saying that the card is blank and the file is not supported.
Any help would be greatly appreciated.

you might wanna try minitool partition wizard on your pc with your micro sd in your card reader and plugged into your pc and when you pull up your sd card im sure youll see your sd card isn't fat32 anymore and is Linux so to fix youll need to right click on the sd and click delete then put back into your phone and format then youll have it working again, but sorry to say your files are now gone on your micro sd

"Inserted SD card unavailable" after Pie update

Hello.
Recently updated to Android 9 OTA and removed MicroSD card to backup files on PC. The handset doesn't work with MicroSd cards since then Tried different cards, formatting them exFAT on PC. The built in android formatting tool doesn't work. Starts at 20% and stays that way. When it says done it goes back to saying that SD card needs formatting. Any suggestions?

It maybe the card or the card reader. Have you can format the SD card on your computer? If it worked then it's probably the reader. You be could try vold magisk module but honestly it's probably a hardware failure rather than software issue. Maybe try to get compressed air to clean out the reader. Only other thing you could try is install the update again... Could have been install issue. So try the install again. One last thing here if the card works on computer you can use ADB push to push the apps or data onto the phone. All the info for any of this is available with a search please try to use next time it if you didn't this time. For all but ADB walkthrough just read top ten in this guide area.
