SD card issue

[musicsfx]

So, I have an android 4.0.4 unrooted device (not-so-popular-brand) and it worked perfect until a day. I don't know how, but my sdcard it's not working anymore. I can still use the files I have on it, but i can't delete/write another files. It just stuck like this. If i delete something it comes back, if I try to install something it disappears, all after a reboot. I'm extremely frustrated.

I tried:
Formatting sd card with an USB cable.
Formatting sd card with an card reader.
Erasing all card data from Settings->Storage.
Formatting using some programs like https://www.sdcard.org/downloads/formatter_4/.
Factory reset.
And some more stuff I found on google.

My specs are:
Sd card - 4Gb
Android 4.0.4 Os
Ram: 512MB
1Ghz Cortex A9 Processor
2Gb internal memory (1Gb user available)

Some apps:
ES File Explorer
NOVA Lancher

Any idea is welcome.
PS: If you need other informations about my device tell me and sorry for my english(not my native language)

An Sd card does not have an infinite life. It may be starting to show it's age. I would try to back up any files you really need, and get a new one.

Thank you for this fast reply, but I bought this card like 2-3 mounths ago. Is this too much for a sd card?!

No. I was under the impressio it was older than that. I honestly don't know what os up with the card.

You may have somehow locked, or protected the card. It sounds like you've formatted the card every which way from Tuesday, and you still have data on it that cannot be altered? Old cards used to have the flip switch to make them read or write only, but those are not on micros. I dunno man. I would see if you can somehow detect if it is protected or not. root explorer (if you are rooted) can detect read/write settings.
