I used a micro SD card in a Nokia Smartphone for years as internal storage. I ejected it to test if *another phone* detects this type of SD card. Although we planned to just see if it is detected, certain off-topic factors led to the acceptance of Google's suggestion to '*format it as internal storage*'. **As long as my phone still remembers the decryption, is there a way to recover** my Photos, GPS-tracks, Text-Notes and other data, despite being *encrypted* with the known key *and formatted* by another phone? ---------- My assumptions: * data from a non-encrypted card can often be retrieved mainly because the raw data still 'looks like' photos, mp3 etc; * encrypted data doesn't 'look like' anything, so recovery tools won't find anything; * Even if my phone doesn't care about data parts but about some 'yes I am your encrypted storage do not format me' file, a recovery tool would need the *decryption information* to look for the original content (i.e. *how to extract it* from the phone plus tell the tool?) ---------- Side note/non-duplicate: Similar questions that I found always have somebody losing the decryption key and I agree that recovery should be impossible in those cases.

I have to delete all the data on my Android device, without being able to hard reset or factory reset my phone. To explain this precarious situation, my phone has a _Power_ button, that no longer works, my screen is barely functional, with lines across it, and the _Micro USB_ female port, is barely functional as well, only connecting at specific angles and positions. I tried the hard reset approach, and my phone is currently stuck in a bootloop, attempting to enter _Recovery Mode_, only to fail and try again. I am not even sure, if it will exit this loop once the power runs out, and boot normally, but presuming it does, I will need to delete all it's data before exchanging it. Assuming I managed to mess up the stock _Recovery Mode_ image, recovery.img, I have devised a few approaches, that I will now mention. ## Deleting and entering random data This method involves deleting all files, and then writing random data to it. Here are the steps I have devised, 1. Write a shell script, to use _ADB_ to uninstall all apps that can be uninstalled. 2. Delete all data from emulated storage, using _ADB_. 3. Install _Termux_, and fill the file system with random data, using something along the lines of,

$ dd if=/dev/random of=file bs=64k

I will be the first to admit, this is a dumb and terrible method, but it is the only one that seems mostly plausible to me. My biggest concern, after the fact that it might damage my hardware, from writing such huge files, is the fact that it might not delete the data stored in the root file system at /data. A lot of apps, especially system apps, tend to write there, like _Whatsapp_, and Whatsapp stores it's entire database, as well as some images there, which I am not confident will be deleted. My biggest goal, is to get all my family images and local text messages deleted. ## Flashing stock recovery.img I have considered this method, however it is unlikely to work in my case. For reasons, I was never able to unlock the bootloader of this device, and boot into fastboot mode. There is apparently a way to replace it with the stock image without booting into fastboot mode, but it requires use of the _Power_ button. ## Other options Other options and solutions I can think of include, somehow formatting without entering _Recovery Mode_, or unlocking the bootloader, which should format the system. If nothing works, is having a lockscreen password enough, or can it be bypassed by the manufacturer, somehow? I know given the state of my device, it will likely be scrapped for parts, but I can never be too safe, and it feels like my duty, to do what I can. Which, if any of these are likely to work, in my very specific and precarious situation? My device is [Realme 1 CPH1859](https://www.gsmarena.com/realme_1-9200.php) .

I'm trying to format a 64GB Micro SD card into 70% portable storage and 30% internal storage. My phone runs Android 6, it's rooted with Magisk and I installed TWRP. Unfortunately, I can't successfully do it; I keep getting this error:

C:\Windows\system32>adb shell

It also doesn't work when you try it as 100% internal or portable. I tried formatting it as ext3/ext4/exFAT in TWRP and then using adb but it didn't help. I'm unable to find any fix on the XDA forum/Reddit. I'm pretty sure the Micro SD card itself isn't at fault as I was able to format it successfully using a different phone. (These two "unsupported flags" errors don't seem to be related to the problem). Update: I still can't get adb to format any drive on this phone (I encounter the same error), but I did manage to do it using a different method. First, I wiped the drive using TWRP and then formatted it using the built-in Android formatting tool. I had tried this before, but each time it would either get stuck forever at 20% or make 100% of the internal storage invisible to MTP and only suitable for app storage. However, this time it somehow worked - I have no idea why. MTP and root file manager shows only one drive of 58.90GB, and it behaves like the default internal storage. I will leave this post open as I didn't really solve the problem but more like got around it. Thanks for all the help (and grammar correction of this post :D ).

My Android phone keeps saying my fully working SD Card is damaged and I have only the choice to format it. I tested it on every smartphone I have, the same error. But when I put this SD Card in my laptop or Windows Phone smartphone: - the SD card works fine; - can listen to the music just fine; - no problem when watching a movie from it; - working just one more time on a single Android phone, then the error again. I tested it with chkdsk, no problem. What can I do? How can I skip the formatting?

How can I format or wipe an external hard drive with no partition on it without third party apps? I tried the MixApplications app but it's paid, in fact all apps that I tried to wipe this HDD are paid. So is there another way?

Reading the XDA forums I've noticed some posts around custom ROM flashing instruct users to perform data format in a recovery (such as TWRP) at different times. My question is - should data format be performed prior to flashing the ROM image, or right after it? Does it even matter?

How can I find the file system type of USB drive without using computer? Drive is attached to Android phone and I can see the files in it. I want to know if it is extFAT etc.

On a not rooted smartphone, how do I format my SD Card to a file system of my choosing? Note that I have ordered an SD card reader so I can put my SD card into my laptop and try formatting it from there. But for now, without an SD card reader / without the ability to put the SD card into my laptop. I can do C:\Users\User>adb shell ocean:/ $ I can even see the contents of the SD Card here ocean:/sdcard $ ls ls Alarms DCIM Movies Notifications Podcasts WhatsApp Android Download Music Pictures Ringtones alt_autocycle ocean:/sdcard $ I looked here https://android.stackexchange.com/questions/209347/how-do-i-find-what-type-of-file-system-is-of-an-attached-usb-or-sd-card/248645#248645 Currently it's showing as sdcardfs or more specifically vfat (which apparently is FAT12 or FAT16 or FAT32) I'm interested in formatting it myself and choosing the specific file system.

How can I view what file system my SD card has been formatted to? e.g. if it has been formatted as FAT12 or FAT16 or FAT32 or NTFS or exFAT

The storage on my Android 11 phone (Fairphone 3) was running out so I mounted a Lexar micro SD card to increase storage. I now realise this was a mistake but not knowing any better I formatted it as internal storage as that is essentially what I needed. Now any photos I take will not show up in Gallery, Photos or Drive and neither can I see them on the SD card - so they're essentially not being taken. Taking a picture within Whatsapp is possible but then impossible to send because the file format isn't "valid". (And when I manually eject the card, the camera won't work at all.) I've come as far as thinking I need to format the SD card to portable to fix this? Essentially I want to undo ever putting it in there, I'd rather take low storage. BUT while there are no major picture or document files on the card, I noticed the WhatsApp Databases and Backup files and I'm worried that formatting will wipe my WhatsApp account. It's also backing up to Drive but when I try and do a manual back-up without the SD card in (thinking I can then uninstal/reinstal Whatsapp and load the most recent Drive backup after formatting + losing the SD storage) it tells me "Backup skipped because internal storage not available". So could someone please confirm: - Do I need to FORMAT my SD card to fix the Photos issue? - Will I lose my WhatsApp chats if I format because it deletes the Databases? - If so, is the only way to save it to secure a Drive backup, format the SD card, then uninstal/reinstal WhatsApp and load the Drive backup? Thanks!! TL;DR how do I get out of an internal formatted SD storage situation without losing my WhatsApp history?

I'm using an app that allows me to download data for offline usage. The app is setup to store the data on my 64GB SD card. This all works fine, however, when I downloaded a larger set of data, i.e. some 6GB of data, that data used up some 30GB of storage space, and filled the SD card. I was baffled in the first place, so I had a deeper look at the data. It turned out that the data consisted of some 120'000 files of 40KB in size, some larger, some smaller. I next had a look at the SD card and found it was formatted as exFAT and to use 128KiB blocksize (FX tells me so, I guess this should read cluster size). I'm thinking about reformatting the SD card to use a smaller cluster size, say 48KiB or 64KiB, which would be more suitable for this kind of data. Can this be done? Any inhibitors?

I am trying to increase the internal storage of my realme narzo 30a phone. but it doesnt support format as internal. so i enabled usb debugging and used

set-force-adoptabe true

via

. Then i formatted it as internal storage from google files app. as soon as i press done, i get a popup saying sd card is ejected. I also tried mounting via adb using

mount private DISK;VOLUME

but i got an error saying its inaccessible... If I dont press done after formatting using files, it doesnt seem to get ejected, but it is not shown in storge... is there no way to use sd card as internal storage? what is funny to me is that it works just fine on a moto e40 i tried it in... even the speeds were not bad.

I have an Android 12 with MIUI 13, Xiaomi Redmin Note 11 pro 5g. sdcard works flawlessly, configured as an removable/external memory. I reboot the phone, and it asks me if I want to use it as an internal or external memory (portable). If I choose external, the only option I have is to format it and loose all my data. This is a lot of overhead: copy old data, reformat it and copy again backup up data. I already hat to do so when I upgraded from MIUI 12 to 13. I don't desire to do this every time I reboot the phone. Any hints to avoid all this fuss? I've checked with fsck that the partition has no problems. Related info: - https://c.mi.com/uk/post/12553 **UPDATE** Finally I've decided to: - backup all my data - format the sdcard with the phone - extract the sdcard - recopy all the data (a very lengthy process with a 128 Mb card) - reinsert in the phone and now it offers me to format it again in order to use it.

Device: Redmi Note 11 I formatted a SanDisk SD card as internal, using the Android's native file app (com.google.android.documentsui) but now I can't see the card anywhere. However when inserted, the phone storage info shows available space of the SD Card. How do I make this SD card as portable again?

I have just flashed a new ROM and the microSD card is gone. It appears in the notifications as "unsupported SD card". Is there a way to fix it?

I've accidentally formatted my phone, via. fastboot oem unlock. I've already tried Wondershare , EaseUSMobile Saver. Actually, I need my photos which has been shot by camera. Till now I'm only able to fetch social photos. PS - My phone is rooted & flashed. Any suggestions?

Someone put CyanogenMod on my T-Mobile Galaxy S4. So I tried to unroot and return to the original by watching [this Youtube video](http://www.youtube.com/watch?v=yEJSv9MrVAg) and using this method.This is what I have gotten from the phone: Odin Mode Product Name: SGH: M919 Current Binary: Custom System Status: Custom Knox Kernel Lock: 0X0 Knox Warranty Void: 0X1 Write protection: Enable eMMC Bust: Mode: Enable Start [224, 1440] in red SW REV. CHECK FAIL : fused : 4, Binary: 1 in red. On the PC screen, in red, it says **Fail!** In the message box, the last line read: All threads completed: (succeed 0 / failed 1). Now I tried to reboot the phone, I got the same Odin Mode thing plus: CSB-CONFIG-LSB: 0X30 minus the two lines in red. In the middle of the screen, a phone, a yellow triangle with an ! mark in the center, a PC screen. Below says: "Firmware upgrade encountered an issue. please select recovery mode in Kies & try again." I have no phone now. I know I didnt reset binary flash. So people told me to format and reinstall the OS. Please help me to go back to stock version.

I formatted two different SD cards with Android 8, 9 and 12. In all cases, the SD cards are write protected for my laptop (SD card reader) - but not for the Phones, or when connecting phone via USB. In those cases I maintain write access. Any pointers on how to undo that?

I have two SanDisk micro SD cards, a 8GB one for storing my photos and files in a Sony Xperia XA1, which runs Android 8.0 as the OS, the other one is a 128GB used in a Sony Xperia L3 phone, running Android 8.1. Since both of them had problems after years of usage, I bought a new phone, which is a Motorola e40, which runs Android 11. When I transferred the micro SD card to the Motorola e40, it said the micro SD card is corrupted and asked for re-formatting. It happened to both of the micro SD cards. But the cards were actually working when I put them back to the Sony phones. I wonder if the problem is on the OS. Does Android 11 use a micro SD card with a file system format different from that used by Android 8? Or is it the problem of the different phone brands? I recall that both cards had not been formatted by me before when I used them for the Sony phones, so they should be pre-formatted by the manufacturer. Also, the Motorola phone asked whether I would like to format the card as internal or portable storage (I did not choose either of them because the cards actually can work in the Sony phones and they contain data). But this option never appeared in my old Sony phones. So is it a property of the phone or Android 11?

I have tried clean all command in Diskpart and it took an hour to be completed but at the end nothing has changed. I think the SD card is locked and when I try to format or re-partition the disk, either it will show a successful result or it will return "Windows was unable to complete the format" error. I have tried to format it in Linux (this answer ) and Android as well but no luck. Is there a way to reuse my SD card as a portable storage?
