Reboot on "Preparing SD Card"

[Se7enLC]

I just got a 32GB SD card and am now experiencing a reboot whenever I unmount and remount the SD card. Other than that, the card works perfectly fine.

Steps to Reproduce:
1). Settings | SD Card and Phone Storage
2). Unmount SD card
3). Mount SD card

Notification bar will say "Preparing SD Card" at this point for quite awhile, and then I will see the bootsplash (not the full hardware reset).

Is anybody else experiencing this? Anything anyone can think of that I should look for?

I'm running 6.0RC1

this happened to me. formatting the sdcard fixed it. this will erase all your stuff on your sdcard so back it up to a computer before formatting.

I just tried that - formatting the card does not fix the problem. Are you using a 32gb card?

I also had the same issue, figured out it happened when I unplugged the USB from my computer on accident while transferring files, after that the sd card could not mount properly after transferring files or when I restarted the phone it would always reboot. I did reformat the card and now it works fine, it is only a 16gb card though, so if your using a 32gb it might be another issue. I would try another reformat, if it doesnt work then I would look through the forums some more.

I've reformatted a few times (it's a brand new card, so there wasn't much on it anyway). I get the problem when I unmount and remount even if I'm not even attached to a computer at all. My random uninformed guess is that there is a timeout for how long the "preparing SD card" step should take, and since the card is twice the size, that step takes twice as long - and something times out and reboots.

I'm going to attach to adb and run logcat when I get home so I can see what messages show up right before the reboot, maybe that will give me a hint.

Does it work fine with just the 16gb sdcard?

Yeah, never had a problem with the 16gb

What method did you use for reformat? I had problems using the Droid format option and used the RM option to partition and that made it work again. Not sure if that makes a difference, I read awhile back that the Droid was not actually able to format a 32gb sdcard even though I know others are using them. However if its a brand new card, was it ever even formatted for the phone, properly?

The card came formatted vfat (fat32) and shows the full capacity both in my PC (linux) and on the droid. I reformatted the card from the phone and that seemed to format properly, but still triggered the reboot when I tried to mount it. On boot, the card mounts fine.

I don't think using RomManager for partitioning is recommended or needed anymore - there's no need to partition for Apps2SD when using CM6, since it uses the Froyo method for apps on the SD card.

Ok, I guess I don't really know what could be causing it, your earlier post made sense with the load time issues, but I had a lot of trouble finding any real info on the subject when when I was having my problems before. As far as using the RM partition/format option, it was the only thing that would seem to work when I was trying to reformat the card for some reason so I took that route, the phone format option kept causing my phone to reboot. Would like to know what you come up with for the cause of the issue though.
