This USB device had only one partition, but now it has two partitions and the second partition has an offset of 8MB, so I assume that there is a problem with the file system or partition table.
I have tried SystemRescueCd, gparted reads the usb as read-only.
Here's the picture attached:
tried testdisk here's what i got:
Disk /dev/sdd - 134 GB / 125 GiB (RO) - Generic Flash Disk
Write access for this media is not available. TestDisk won't be able to modify it.
- This media may be physically write-protected, check the jumpers.
