How to fix Device not recognized on USB flash drives and encrypted USB drives

Data Traveler Hardware encrypted USB data storage.First, let it be said this is general advice if you can’t read a usb drive and you understand tampering with the device could lose all the data contained in the device.

I had a recovery job come in for a hardware encrypted USB key, when plugged into any USB port:

Device Not Recognized was the message.

This customer had flown to Grand Cayman and his encrypted data drive would not identify to let him get to his data.

 

In some cases salty air can corrode the contacts on USB devices, or pocket lint/trash can obscure the proper contact points on a flash drive from being readable.

You can take a standard Q-tip and crimp it down, pull off some of the cotton and push the stick back and forth to clean the USB contact points.

To do this the q-tip must be fairly tight fitting between the metal frame and the circuitboard on the end of the memory stick.

 

This quick cleaning kept him from having to have actual data recovery done on his device.

 

We then set him up a second device with truecrypt encryption and transferred all his documents onto that device in case the device in question failed.

 

How to fix a Logitech M505 mouse that stops working (unifying adapter)

 

Logitech M505 wireless mouse with Unifying AdapterQ: Help, my Logitech M505 Mouse stopped working. I’ve changed the batteries but can’t get the mouse to work.

A: Often times wirless mice have a button to reset, this one does not.

Here’s how I solved the problem:

Take a pair of pliers, crimp the end of a Q-tip flat for about 1/2″.

Put the q-tip into the USB Unifying adapter and push it in and out along the contacts (there are 4)

This will clean any debris off of the contacts and allow them to work.

(in this case they could use it on their desktop, but not their laptop)

 

This trick will work to fix some flash drives that you can’t retrieve data from (anything that keeps the USB from communicating with the port on the computer, dirt grime, oxidation etc)

Whitespace wiping, removing personal data while leaving the OS intact

A few of you out there have been asking me for how to wipe a hard disk for computer donation,
You can use a bootable nuke disk to wipe the drive and OS in one boot and answer a couple of questions ensuring you wish to toast your hard disk, but if you want to give that laptop to little Johnny, or Sue to use for school and you want to leave your OS intact it becomes more difficult.

Instructions for white space wiping and reasons for this:

If you wish to wipe the data from a partition, Simply delete all the information you wish to destroy, remove all internet caches, delete all history, and all temporary folders, a good program for this is ccleaner from ccleaner.com.

Then download TrueCrypt, and make a file container as big as the rest of the hard drive that is empty.
Once complete, you will have overwritten your data with an encrypted empty drive, thus destroying any file handles and other objects.
Then delete the file container you created.

If you do this 3 times, it’s almost impossible to retrieve anything from the drive, however with an electron scanning microscope, or a special hard disk circuit board and a good head eschew program it is still possible to retrieve latent data from the edges of your overwritten data.
