External devices are shown corrupted even if not corrupted - General Questions and Answers

i have a rooted moto g 3rd gen (with twrp recovery)
phone specs: 2gb ram,16 gb internal storage,android 6.0.1 model XT1550
So till yesterday my phone was working fine until i took a few videos and suddenly the phone gave a notification saying my sd card is corrupted and needs formatting i always kept it as portable device . I took out the card and inserted it on my friends cell (same moto g3) and it was working fine... after that i inserted the memory card using a card reader and an otg and still showed it is corrupted. i inserted a new sd card and it showed that is corrupted too... i tried doing a factory reset and clearing the cache n dalvik from the twrp recovery but it gave an error saying "UNABLE TO MOUNT STORAGE" when the memory card was inserted .... i did the same without the sd card and it worked.. but again when i insert any card or otg card/pen drive it shows it as corrupted and suggest to format it..even after formatting it does not solve the issue formatting stops at 20% and says can not format..
PS: )There is no fault in the sd card it works fine with ALL other devices n my laptop the problem is with my phone only....
also am posting it in a new thread because i didn't find any relevant answers....

Damaged SD Card

Hi guys,
My phones micro-sd card has been acting strange and was not being recognized at times by my phone. I then proceeded to put it in its SD card adapter and put it in my Mac and got an error saying the card was unreadable. I then put it in a reader on my PC and everytime I try to access the drive it gives me the 2 errors, "You need to format the drive...etc" and after clicking cancel it says that my drive is an unrecognized file format.
Recuva says it can't read the boot sector and running chkdsk gives me the message that the file format is RAW.
Just tried running ReclaiMe file recovery and it says the card is only 30.6MB while it is actually a 32GB card.
Do you guys think there is any hope? Or should I just move on?
Any help would appreciated. Got a lot of pictures and music I would love to save on the drive, plus ROM backups.
Thanks so much

I've killed an SD card before.. not sure how.. it had been partitioned EXT3 for a rom on a desire.. then re-formatted to normal..
but the problem came months after without notice one day the camera was failing and the gallery wouldn't open..
I tried a new SD card and things were fine so I figured the SD card died
Try to use MiniTool Partition Wizard on your pc, and delete ext partition and swap stay only on fat32. if that does not work format your card to exfat. If that doesn`t work try use program "winhex"(before i used it, my computer hadnt read my card). I repaired my card 3 times these methods.
You can use this ONLY on memory card reader.

[Q] SD Card Not Detecting

I recently encountered a problem with my HTC Sensation (Running on Carbon Rom with Android 4.3.1), that suddenly it started to drop signals. So I tried restarting the phone and by accident I removed the SD Card while the phone was still switched on. Now the phone doesn't detect the SD Card anymore when I insert it. I don't think its a problem related to the card reader, as it prompts me to format the SD Card after I put it to the phone, however, when I allow it to format the SD Card, it won't be formatted. So I tried inserting by manually formatting the SD Card, but still it failed to recognize it. Afterwards, I tried several times by clearing cache, and trying to mount it from the recovery with no luck whatsoever. Plus, I tried inserting another SD Card (which was not from an Android phone) and still the result was the same.
Would really appreciate if someone can help me out on what should I do?
Thanks in advance!
