Restore USB from weird state

[NunoLava1998]

After a KDE crash during a upgrade, somehow my 16 GB USB was likely corrupted. Now Manjaro Linux 16.10 thinks i have 2 USB sticks, one that gives signs that usually means the kernel is going crazy or that your USB is broken, as you can't mount or format it.

 

I installed Archbang on one of them (the only USB that you could manage) and booted from it. And behold... a blinking cursor.

How can i restore this?

(please reply fast)

Is there data on it you care about?

 

You can just reformat it.

when i try to reformat the working partition and install anything on it nothing works when booting like if nothing was installed

when i try sdb5 (which changed to sdf5) which is the unusuable...

"not enough blocks" or "too many blocks"

EDIT: the unmountable sdf5 doesn't even show in the drive list thing lol

Ten to one it's broken. USB drives tend to break really damn easily

It seems Manjaro just tried to recreate sdf1 and made sdf5, but again, couldn't sdf5 be the USB and sdf1 be that stupid CD that shows up when you plug it in for "encryption and security and works on windows and mac and linux even though it only works on windows to be real"?

 

But sdf5 seems to be dissapearing like Manjaro regret it. Maybe i didn't install Arch correctly, meh.

dd if=/dev/zer of=/dev/sdb

 

this will clear all the data on it, then try again

dev/zero

seems legit

 

 

EDIT: did it

not doing anything

looks like sdf5 is indeed a imaginary partition, lol

i actually corrected the typo lol

see above edit

[NunoLava1998]

did zero on sdb1

 

 

 

4 GB... um

i am PRETTY sure it's 16GB, not 4GB

unless this is running in 32 bit mode, but this surpassed the 32 bit limit

 

 

EDIT: now the unusuable part can be accessed easily, i'm just not allowed to mount it, but sudo is love

"bad superblock on /dev/sdf1,"

 

seriously

Repartitioned using GParted as it was available. One unexistent copy that Manjaro loves to make, and the real USB! Finally, i was spending 5 hours on this.
