2 questions on Micro SD cards and OS updates if anyone knows:
If an OS update is performed with an SD card inserted, will part of the OS end up on the SD card since the storage is merged? Meaning if one later removes the SD card, would this result in a corrupt OS/be impossible to reset the device?
Can you remove an SD card, perform an OS update, then reinsert the SD card (and hard reset) and still use it again? Or would the device security change and not recognize the card as being married to the device?
I've added an SD card to my phone recently and the OS seems stable (no unexpected resets or data loss) but it is a tad slower. I do get time-out issues on occasion when syncing in Zune, but otherwise things are fine.
I did try to update last night and got a time-out error installing the OS update.
My concern about item #1 is that if the SD card fails or I decide to remove it in the future, I might not be able to boot/reset my phone.
My concern about item #2 is that if the SD card isn't recognized due to the security lock down, it'll be useless.
Even without an SD card, my internal storage seems terribly slow. on WP Bench, the "write to storage 5 MB x 25" portion of the test takes like 5+ minutes to complete. Is that normal?

Just bought an ASUS HD7 tablet - specs show it will take a 32gB SD. I have a 32gB SD in my Nook Color (CM7) that has a lot of music. Let's bring it over and try that on the new HD7. I unmounted the SD card on the Nook, powered off and powered off the HD7. Inserted the card and powered the HD7 on. After boot, it claimed to be "preparing the SD card for use". I thought, "Great". But, sadly no music. I inspected the SD card with ES File Expl - it identified the SD card but with only 114mB capacity. The card is mounted but shows folders with no files/sub-folders I know are there when in the Nook C.
I pulled out a brand new 32gB SD card - never been used - right out of the blister pack. Dismounted, powered down. Inserted fresh card, powered up, "Preping card - yada-yada". But this time the new card shows an even smaller 96mB capacity.
So obviously I'm missing some key Android-ness point with respect to these cards. Since I've never actually swapped them like this, I'm sort of treating them like a "USB flash or thumb drive" and maybe I shouldn't. Am I just ignorant and missing some sort of prep step or "mount this card" command? Is it possible this reader is defective? (Remember - it recognizes, mounts and unmounts without incident...) Is it a fact that I can independently move these around from device to device in Android even if my versions are different (quite different in fact)?
Any guidance appreciated.

There is no prepping required for Android to recognise SD cards. Usually, they work just as thumbdrives on a PC. The "remove hardware" process should be observed because this will ensure that any cached data will be written to the removable media and that the files are all closed.
With Android, in Settings-Storage, there is a Mount / Unmount. This is similar to add or remove the storage media, eg, SD card.
You can try this workaround. As before, when switched off, insert the SD card to the HD7 and then switch it on. Go to the Settings-Storage and you should see the SD card details. Do an Unmount, remove the SD card, wait a while and then re-insert the SD card and do a Mount. You might be able to acess the data on your SD card by now.
If this still does not work and since you had just bought the HD7, bring it to the seller and have it checked. Also bring along both your SD cards that you had tried to use, as well as the Nook so that you can prove to the seller that there is nothing wrong with the SD cards.

Answer comes from another forum:
Try a Safe Mode boot. Forget it. No help.
But...
•Power down
•Pop out SD
•Power up
•Say prayer
•Android shows the desktop
•Settings // Storage
•There's the Internal Memory restored to its correct position
•While still powered on, pop IN the SD
•Another prayer
•"Preparing SD Card..."
•Poof - it shows now as the second selection
•Done
Bonus: Tablet now runs smoothly just like it was.

I recently flashed the official 6.0 EU Retail rom onto my 3rd gen Moto G and decided to buy a 32GB SD Card to use the new adopted storage feature, but it seems to be completely broken.
Every once in a while my phone stops reading the files on the SD Card, when I reboot they are all gone, but the space on the SD Card is still taken up.
There is nothing to do besides reformatting and pray that the same thing won't happen again, well, it happens every time after 1 or 2 days.
It also seems to happen or I just notice it when I connect the phone to my PC to move some files over (when doing it I always have to go into developer settings and reconfirm to use MPT as action when connected to a PC via USB, because if I don't do that the PC just recognizes an empty device).
Now I've heard that the adopted storage feature is bugged for a lot o other phones too, which is awful for us with low internal storage, having only 4 GB of free space doesn't leave me the choice to use the SD Card as external storage because the pre6.0 feature of moving over apps to the SD card just got dropped in favour of the broken Adopt SD Card feature.
Is there anything I can do to get my ghost files back, so I don't have to reformat my SD Card every time and lose all my new media every time the bug comes up again?
Card is a Sandisk 128GB Ultra MicroSDXC A1 card.
Card is formatted exFAT.
Card can be mounted, opened, and read/write with no problems via my laptop when plugged directly (SD slot).
Android (LG G5, LineageOS 15.1) says card is corrupt, is trying to make me format. Card initially set up as "Portable Storage".
Took FOREVER to move music onto this card, as artists had to be moved one at a time or transfers would fail, so I'm trying to avoid formatting.
I've tried rebooting the phone, repairing the file system using TWRP Wipe command (fails with error code 1), and mounting with a clean eject via Windows 10 on my laptop using the SD card slot. Nothing has made an impact, stupid phone still won't allow me to use the card.
If anyone has any ideas why this is happening, or how I could potentially fix this without having to wipe the card, I would appreciate it. This thing has been a PITA since I got it, I thought it would be awesome having such expandable storage on my phone (I'm a weirdo who doesn't use streaming services) but I've had nothing but problems so far. I have to be careful with how I transfer files onto the card or the transfer will take an (appropriately) long time, act like it works, but then the file just won't be there. Now I've finally gotten the card loaded up, and after a routine phone reboot a few days ago, the Android OS is trying to say it's corrupt; This is also making me worry that this will continue being an issue in the future.
Running "chkdsk E: /r" on my laptop is revealing a couple minor corruptions inside the directory, and volume bitmap. It's hanging on verification/completing now.
Is it possible that I have a bad SD card? This thing has seriously done nothing but suck since I've been trying to use it.
Edit: Unless someone tells me otherwise, I'm pretty sure this is a bogus/defective SD card. I simply cannot believe that flash memory would perform this badly. I'm going to return this card (bit of a PITA since I ordered it online) and buy another one locally.
I got the A22 5G and I like it apart from one huge issue.
I encrypted my sd card (256 GB) and transfer rates are unbearably slow.
If I copy a 2 GB file from the internal storage to the SD card it will start ok (20 MB/s) but this is likely only the cache.
Soon it slows down to ultimately 10-50 kB/s which is unusable, copying was not finished after 15 min.
When I decrypt the card again everything is as fast as expected. I checked the SD card on another phone, no speed problems.
Back into the Samsung and encrypted it is unusably slow again.
Did anybody have a similar issue?
I returned the phone.
In case somebody else runs into this issue I'm afraid I could not determine the cause.
I tried adopting the SD card as internal storage via adp commands but Samsung has even blocked this now.
One can partition the SD card as internal storage still but it is not possible to trigger the migration.
This means any normal application will still only see the internal phone storage and not the sd card's.
Clear system cache.
Low level format the card, then format it again with the phone.
Hi, my micro sd suddenly stopped being detected by phone. Settings app pushed out a notification saying I need to format my micro sd. I tried to format it but it's stuck at 20%. I restarted my phone. Still the same message. I took it out and inserted into card reader and plugged into windows 11 computer. Everythingbis still there. I can still copy and move files of micro SD in windows 11.
2 possible culprits.
1. I restarted my phone
2. I accidentally toggle on "Force allow apps on external" (i have since toggle this off but issue still persists)
How do I fix it so I can use my micro sd in Android phone?
Possible causes for Android not recognizing your SD card:
1. Often, the SD card in the slot simply has no contact with the receiver. Then it is inserted into the device, but can not connect to your Android smartphone. It can then help to remove the SD card once and insert it again. If it clicks into place correctly, the card will either be recognized or there is another problem.
2. The card itself could also be the reason why your Android device does not recognize it. Have you inserted the SD card the right way round? You will usually find a small symbol on the slot that indicates the insertion direction. Another problem could be the write-protect switch of the SD card. It must be deactivated.
3. If you are using an older Android smartphone, the SD card you want to insert might simply be too big. Many older models only support memory cards up to a maximum of 32 gigabytes. Sometimes even only models with up to 16 gigabytes are possible. Information about this can be found in the manual of your Android device. In an emergency, you can also ask the manufacturer directly.
4. Of course, a defect in the SD card is also an option. You can rule this out by inserting your card into another device and testing whether it is recognized. If this is the case, the SD card works.

Hi. Thank you for your response. I did an additional test.
I inserted the card into a card reader then plugged into my phone as otg. It worked fine. Everything was accessible.
So that concludes the card reader slot is the issue. But my question is that the card was inserted in the phone since a long time ago and i never opened the sim tray even just before it started malfunctioning. Is there a possible software issue or it is 100% sure it is a hardware problem?
