Can I repair a physically broken USB drive?

My friend just wrote to me, all in panic, that he had broken his USB with his math homework for tomorrow. (Yes, no other backups, just that.) It looks like this now:

Another option would be to see if Word…

root@rapunzel:~# dd if=/dev/sda of=/tmp/test count=1…

Is there a way to power down a USB device using software?

Is there a way that I can power off a (specific) USB device completely using software from a Linux machine?

I want to use this to power off (so that the LED is off) a (single) USB stick.

Do you know any method to achieve this? E.g. using /sys/bus/usb or the like?

Opened up a USB stick and it looks a bit odd

We opened up the case of a USB stick (that didn’t work before we opened it) and it looks like this:

Has the memory been taken out of it or do some USB sticks actually look like this? Note that it was probably cheaply-produced.

how to write protect a USB key?

I’m looking for a solution to write-protect the contents of a USB key. The idea is to prevent its contents from being inadvertently removed by the user or changed by malicious programs not to restrict the re-cycling of the key for something else.

Here is a summary of my findings so far:

Some keys have a switch which makes them read-only. Unfortunately this is not…

Why Do Some USB Cables Have Two USB Connectors at the End?

I’ve recently bought an external hard drive enclosure and it had arrived with an USB cable, with one USB connector on one side and two on the other. Why do some USB cables have two connectors while others do not?

Verifying USB connection speed (USB 3 or USB 2?)

I’ve purchased several new USB 3 capable drives to use with my new (USB 3 capable) laptop. They connect ok but I suspect they’re silently falling back to USB 2. The sustained transfer rates I’m seeing are around 30 Mb/s for both reads and writes, well within the practical limits of USB 2. One of the drives in particular is rated for transfers well…
