Restore crashed USB flash drive
by aiszisz from LinuxQuestions.org on (#5CB02)
Hi folks!
It's funny and awkward at the same time, while I tried to solve an issue with a windows iso I caused another one :)))
I followed a howto and gave this command as root:
ms-sys -7 /dev/sdb1
It should have write mbr to the usb device, and according the output the process was successful but the result was strange.
It created 4 partitions two of them was about 100GB one was some TB but the whole USB device is 30GB. I thought it's not OK so I erased the partition table created a new one and run mkfs:
mkfs.ntfs /dev/sdb1
It started to format the partition (so creating the new table should be ok).
Then I realized I forgot the -f option for fast formatting and I did something stupid. I aborted the process! Now my flash drive is broken.
After I plug the USB device:

Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
fdisk: cannot open /dev/sdb: No medium foundIs there any way to restore my flash drive? I found no threads with solution in any forum. The device is not a fake device it used to work before. I tried on all my USB port and even another linux machine with the same result. Ports are OK the drive is broken for sure. There is no (important) data on the device I just want it to work again.
Thanks a lot!
