RAW usb flash drive no partitions listed after analyze

#1 Post by rickymartino » 14 Apr 2016, 06:49

Hi guys, my friend has given me his USB with important work on it and asked me to fix it because I'm usually good with computers but I have never had an issue like this.

What ive worked out is that some how his usb format has been converted to RAW.
After doing alot of research I tried to use testdisk to analyze the drive, but no partitions come up.
Im believe the boot sector may be corrupted or the partition table, but I have no idea.

Before the scan this is what came up:

And here is the log file:

No partition found or selected for recovery
simulate write!

No extended partition

How do I go about repairing this USB?
Any help is greatly appreciated thank you.
