[Q] Unmount SD - Xperia Z2 Tablet Q&A, Help & Troubleshooting

So tablet gives me the ugly yellow construction sign when I just take out the card physically but don't see any options to unmount before pulling it out. Anyone know how to do it?
Edit: Nvm -> settings-> storage-> unmount for anyone's future use.

[Q] Internal storage mounts as /mnt/sdcard?

I'm not sure if this is normal behavior for Android, but it was annoying the hell out of me that the internal memory was mounting to /mnt/sdcard. At first I figured this was just because I didn't have an actual sd card. Then I got one, and it got mounted to /mnt/emmc. From what i read about other devices this seems backwards? I couldn't get some apps to use the emmc storage.
What I finally did was copy all my data from internal storage to the sdcard and then swapped the two mount points in /system/etc/vold.fstab. Everything seems to have gone better than expected. I now see my 32gb microsd as the SDCARD in Storage and the 11gb internal storage shows up as additional storage. Is there any problem with doing this? I'm still not entirely clear on where /mnt/sdcard/external_sd fits into this.
Here is my vold.fstab after I edited it.
Code:
# internal sdcard
dev_mount sdcard /mnt/emmc 11 /devices/platform/s3c-mshci.0/mmc_host/mmc0/mmc0
# external sdcard
dev_mount emmc /mnt/sdcard auto /devices/platform/s3c-sdhci.2/mmc_host/mmc1
# USB storage device
dev_mount usbdisk /mnt/usbdisk auto /devices/platform/s3c_otghcd/usb
The INTERNAL SDCARD is your BUILT IN MEMORY and SHOULD BE listed as mnt/sdcard. This should be your 11Gb internal memory.
The EXTERNAL SDCARD should be listed as mnt/emmc. This should be the REMOVABLE sd card from the battery compartment.
Not sure but I would guess that you MAY HAVE ISSUES with your setup. With HOW you listed emmc I can see your on cm7. In cm7 there is a setting to change the names/location of your cards. Since you had problems I am guessing it is/was reading backwards from the get go. Someone please correct me if I am wrong.

Thanks for the reply. I guess it was working as intended from the beginning. I haven't had any problems with this while in cm7, but one of my objectives was to get cwm to use the external sdcard for backups. Of course my change had no effect what so ever on where cwm is looking for the backup folder. I'm rolling back my change with my tail between my legs. I wasn't able to find the option in CM7 you spoke of.
This is an annoying problem. I have not been able to find any system info widgets that can display the memory status of the ext_sd folder (external sd card). Its even more confusing because the internal "sd card" is also referred to as usb storage while the ext_sd is referred to as SD Card on some screens.

To see if the button is ticked got to MENU, SETTINGS, CHANOGENMOD SETTINGS,APPLICATION,USE INTERNAL STORAGE
If while your at normal settings if you put them back already and it is ticked in the box, then untick it and reboot. If it is not ticked then tick the box and reboot and see if that fixes it. If your still backwards then AGAIN untick it and reboot. Sometimes settings can look correct but be kind of stuck until you toggle it. Just throwing it out how I would check out if I had your issue. Hope it helps

That's exactly what I needed. Thank you!
actually you could have done that all in the Cyanogen setting's. I had mine set that the /mnt/sdcard was my actual SDCARD... problem became that everything was being installed to my SDcard. I prefer my SDcard as my music/picture/movie storage.
if you are using CM7.1 it's in Setting -> Cyanogen Settings - > Application
The one you wanna change is Use Internal Storage checkmark if you want to change
Yes, That's what RockRatt said above. It works perfectly. Thanks!

[Q] Unmounting SD Card

I have the NT, 1.4.1, sideloaded prior to firmware update (but not rooted or anything else). I like to put my movies on the microSD card to play on the NT, but every time I remove the card from the NT to add movies with my computer, the NT says I should unmount first. Problem is that I cannot find any way to unmount before removing. Is there something I need to do?

[Q] "SD Card Damaged" - no, it's not.

Hi!
Today, I ran into problems with my SD card not being recognized. After booting, the process usually looks like this:
1. Displays "Preparing SD: Checking for errors" in the notification area, options to mount wither SD or internal storage are grayed out, "Unavailable".
2. No notification any more, internal storage is mounted. SD card shows an option to be mounted, but if it is activated, the storage manager hangs.
3. SD card isn't mounted, I get a notification that "SD Card is damaged. You may have to reformat it."
Each of these takes about 10-20 minutes to happen.
However, the SD is actually fine: If I open it in recovery, I can see everything is there and that there is no damage to it. Unfortunately, I have not found a way to access my data while in recovery, and I don't have a reader for a microSD card at hand. And I need that data to know if an assignment for my university is due tomorrow :\ So, any help?
Device is a Motorola Atrix, originally rooted, with CM7 (Neutrino ROM). Tried wiping the caches and fixing permissions in recovery, which had no effect except that it unrooted the phone -.-
Thanks for any replies!

[Q] Do you really have to Unmount Your SD Card to safely remove it?

Do you really have to go to Settings, then to Storage, then press Unmount Your SD Card to unmount it or can you just pop that back case open and eject the SD card? Will it damage your phone or the SD card or both?

it won't permanently damage anything, but it can cause filesystem corruption on the sd card. the chance of such corruption, however, is rather minimal, and i've never run into issues not unmounting.
it is like removing a USB device (CD Card, HDD) from PC without 'safely remove USB'.
it is reccomended to unmount your sdcard when done. my tablet starts to act funny if i remove the sdcard without unmounting it. sometimes android may be writing data to the card and you may corrupt it if you dont unmount it

What happened to unmount sd card in Jelly bean? (Huawei ascend Y320 doesn't have it) Where is it? Is it hidden?

No longer auto mount SD card

Lately my phone has stopped mounting the SD storage when I reboot. I now have to manually mount the SD card via settings which is a pain as most apps I have moved to this storage and appears disabled unless I mount.
Just to make it clear this is the external micro sd card I'm referring not the USB storage or the internal storage.
Any ideas why this would suddenly be happening? Could my SD Card be slowly dying?
I'm on 4.1.2 for sometime now.
