[SOLVED] USB: Read-only on FAT32 (LBA)

So I have this usb

Disk /dev/sdd: 96.25 MiB, 100925440 bytes, 197120 sectors
Disk model:  Flash Drive    
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xb70a3bc7

Device     Boot Start    End Sectors  Size Id Type
/dev/sdd1  *      128 197119  196992 96.2M  c W95 FAT32 (LBA)
.....
sdd                                                                              
└─sdd1 vfat   FAT32 CRIMSON  5C1D-C049                              92.1M     0% /run/media/akx/CRIMSON

It stuck with read-only permission

drwxr-xr-x 8 akx akx 1.0K Jan  1  1970 CRIMSON

d????????? ? ?   ?      ?            ? 'System Volume Information'

Tried chmod all files into 777 and modifying fstab like this:

.....
# CRIMSON
UUID=5C1D-C049 /mnt vfat defaults,umask=000 0 0

All fails

It works fine on Windows & Mac OS

Re: [SOLVED] USB: Read-only on FAT32 (LBA)

What does dmesg(1) say about the device when you plug it in? That I/O error doesn't look healthy.

Re: [SOLVED] USB: Read-only on FAT32 (LBA)

"System Volume Information" this is usually a system-folder only found on NTFS
please check with windows if this drive really is FAT or NTFS formatted
also: if you csn access tge data from windows: backup the files - wipe the stick - do a fresh format and copy the files back

It's FAT32

wipe the stick - do a fresh format and copy the files back

No I wouldn't do that for a reason (this is not an ordinary stick)

Any other solutions?

can you be any more vague on that? I noticed this isn't any regular thumbdrive - who would use a 100mb flash in 2024? but a "System Volume Information" folder is something that belongs to NTFS and doesn'T belong on a FAT32 FS - same with this "LOST.DIR"
whatever that is - looks like some crypto crap - contact the support of the OEM as they do some out of the box stuff

Me for educational purpose

Yeah it happens because Windows did it automatically when I plug it in, not really a problem

same with this "LOST.DIR"

Uhh... It's gone now

looks like some crypto crap

Yer think I've been fooled?

Yes I did run 

fsck.vfat

It's better now as long as I remember to unmount it before unplug the device
