USB refuse to format. Causes pc to crawl.

So I have a SSK 64GB USB 3.0 Flash Drive that I bought around 4 years ago, it worked up until a few days ago. Now when I plug it in to any Windows machine (Mainly my desktop) it will flash the LED for half a second. Then it will turn back on and the LED will stay on, windows recognizes it and asks me to format. Here's the different reactions depending on what method I try:

Plain Windows format- No matter the options chosen the bar does not move, causes all explorer windows to run painfully slow or freeze entirely.

Windows Disk Management- Similar results, sometimes throws up a generic failure message. Pc then starts to make the USB connect/disconnect noise every 20~ seconds.

Windows CMD Diskpart- Stays at 0% when formatting, cleaning eventually says 'could not find the file specified'

Laptop running Kali- Accepts any and all commands relating to formatting that I know of, such as creating partitions, deleting partitions etc. Freezes everything when trying to actually format.

I'm just finding it weird that my various computers can see that it's a memory stick, can see the capacity and partitions on it, but can't format it whatsoever.

Any ideas? I think it must be something hardware related, I've opened it up and checked for any visual damage. Beyond 3 blank connections that may or may not hold MLCC, it looks fine.

Thanks for any help, I know the answer will probably be "it's dead, buy a new one" but it's worth a try.
 


Seems you knew the answer all along. It's not at all uncommon for them to act that way when they fail. The computer is only seeing the controller chip, however if a NAND has gone bad or another component that's essential to the controller communicating with the NAND it'll just freeze up or it'll show 0 or -1 capacity. Unless you need to recover data, it's time to toss and replace.

 


Gah, thanks for the reply. It turned into a matter of personal pride in the end, the damn thing cost my £50~ when I bought it.
