Wierd cwm backup behaviour

Okay, so today I took a cwm backup of my current rom, cm music ed v4...{cwm v5 by tj_style}
I have a habit of uninstalling all less-than-frequently used apps, clearing cache, removing other unimportant stuff etc...so that my cwm backup remains relatively small in size (that way I can keep 4-5 backups simultaneously on my sd card)
Before starting, I checked that I had filled almost ~250mb of my 512mb sd-ext partition...and I had around ~4gb free space on my 16gb card...
However, it took a staggering 1.5 hours to complete my backup! (Normally, it averages to 15-25 minutes)
When I then try to restore my backup, it got stuck at "checking md5 sum" for around 15mins, after which I pulled out the battery, and reflashed the rom (rather than restoring it)
So, in an attempt to find out what went wrong, I checked the cwm backup, only to find that the entire backup was close to 3.5gb in size!!
(The wierd part was, based on previous experience, the backup shouldn't have exceeded 450mb max)

Everything inside the backup was normal, except the sd-ext tar, which was super-inflated...
Inside the tar, there was only a "lost+found" folder (while there should have been other folders as well), and there were only a few big files (very big) and LOTS of other numerous very-small files in it...
The big files aren't extractable, hence I don't know what made them so large...
So I am just troubleshooting the problem, trying to learn what may have happened/gone wrong...
{When i reflashed the rom, cm musc ed v4, everything was working fine, including the sd-ext partition
The recovery also is working fine, except the backup and restore part}
Help would be appreciated...
(P.s. don't tell me to use different recovery/rom/sd card, since that is not my purpose, I want to know the exact problem)

ZTE V970 - disabling internal sdcard problem

Hello there in forum
I have problem with disabling internal memory sdcard in ZTE V970.
I tryed to make everything in tutorial on SP flash tool and it diding worked.
After flashing the phone I got message "PMT changed"
Tryed flash disable internal memory .zip with CWM before reinstalling the ROM, no effect.
using ROM: 1.3 MOD
help me please, I cannot install any game from google play store, because there is "no space in memory"
on the memory setting i got 3 partitions:
- Internal memory (2,46 GB)
- Phone storage (54,97 MB)
- my SD 16 GB
EDIT: I found a solution
You just need the lewa_os_make_sdcard_internal_memory.zip installed via CWM after installing ROM, and the stupid tiny phone storage gone and You can install apps from google play store

can anyone help me solve this problem?

Xperia XA storage

Hello guys, I decided to leave my aging Nexus 5 to come back to the good old Xperia brand, I got myself this beautiful device that is our beloved Xperia XA (got it free on contract so yea that's cool)
image is better than words so here's a screenshot:

}
my question is: Why do 5.9 + 3.1 = 12 ???
PS: cache is empty
Thanks in advance!

I think it's because the app don't show you all partitions. If you use third-party app or TWRP you will see the difference (and the truth).

oh alright so, thanks a lot mate !

I'm having a problem with storage too. I tried using adoptable storage but something went horribly wrong to the point I have to reformat my whole sd card as well as my phone. Is there a definite (like safe-proof) way to do adoptable storage?

Works fine for me, just a display bug who show wrong memory size. I use "root essentials" to enable Adoptable Storage (full, not mixed). Format your SD with Gparted (don't work with default Windows format tool) in FAT32 before enabling it and after disabling it to avoid corrupted SD.

Hmm, I'll give it a try then. I sure hope everything goes well this time around. T'was really a pain in the arse.

Resolving Bootloop has removed my Internal Storage

Yesterday I got all my root set up and working fine on my Redmi Note 9 Pro using Magisk (albeit without TWRP installed as I didn't know anything about it at the time) then I decided to install the Smali Patcher module with Magisk so that I could Spoof Pokemon Go with my son in the evenings. I created the module no problem, but when Magisk flashed it, my phone bricked and got stuck in a bootloop to fastboot. I eventually got TWRP installed and factory reset my phone in the "WIPE" menu, I used the standard Wipe that deletes user data etc then factory resets the phone. Everything seemed fine, I was able to set up the phone as per normal until after about half an hour I noticed none of my apps had installed yet. I went into the Play Store and most of had a "couldn't restore" error on them and clicking on one and trying to force it to install would come up with an error about insufficient storage space.
I plugged my phone into my PC to have a look and to be amazement, Internal Storage doesn't show up at all, only the SD Card shows. After over an hour, only one or two apps have successfully installed so I assume they are installing onto the SD card and that's why they are taking an absolute age to install. Most of the apps just flat out won't install so I can pretty much just make a phone call, that's it. Am i right in thinking I have corrupted my Internal Storage somehow and the OS is now isntalled onto the SD card? Maybe the Internal Storage has been formatted and not reallocated or something? How do I go about restoring my phone to how it should be ie 64gb Internal Storage.
I have tried restoring to factory settings again and it made no difference,

copy of big files from pc to microsd return "Error trimming file" message error

Hi, I have a problem that I don't know how to solve: when I try to get files bigger than 125 MB teracopy show "Error trimming file" error message.
The transfer is made with teracopy from a windows 7 pc and landrive app ( https://play.google.com/store/apps/details?id=fr.webrox.landrive&hl=it&pli=1 ) on android.
I don't think that it's bug of teracopy or landrive, because it's happen only with files bigger than 125 mb and not with small files. For this issue I have written a question here ( https://forum.xda-developers.com/t/...ing-kernel-and-compile.4547375/#post-88123973 ) in particularly the part related to ext4 filesystem but nobody has answer me .
How can I solve this issue ?
You can see error in the following screen

Update : I have scanned microsd with hdtune and all sector are ok (green)... there is a bug? Problem occur with galaxy S9 snapdragon both with Android 9 and Android 10

For the Multimedia Card and the SD card it is the ERASE command, which performs a non-deterministic TRIM operation. Non-deterministic TRIM means that after an ERASE command a new read of the respective block number ( cf. Logical Block Addressing, LBA for short ) returns undetermined data. This can be data from other blocks and also different data for each read attempt.

Why is called ERASE command if I'm making a copy to microsd? How can solve this issue? What is the cause?

Ask developer of the app you used this question.

so You think that is a problem related to teracopy and not to android?

It in no case is Android OS related: it happened PC side!
I'm pretty sure the error occured because you didn't perform a Copy but a Move.
If you would do a Google search for "Tera Copy Pro error trimming file" you probably can get the reason why this error occurs.

no, I'm sure to have performed a copy and not a move... are You sure that isn't related to file system (and/or cluster dimension) ? Even because I have format microsd to windows and considering that it was of 128 gb, I can't use FAT32
