USB Pen Drive Data Recovery

Got a call from the customer he told me that he is having one USB pen drive of 2GB which is stopped working & he want to recover his data from the damaged pen drive. I asked him to send the pen drive to me I will try to recover your data if possible.

He sent the pen drive to me …. On visual inspection from outside seems Ok no physical damage.

I connected the drive on my setup for further diagnosis. I found Drive is not detecting. I again phoned him & confirmed the same symptom.

Opened the Pen drive for inspecting inside.

Drive is detected and showing the size of the Data contain.

After exploring the data; Shared File/Directory structure to the customer for confirmation & he confirmed the data & after finishing the job I handed over the pen drive to him.

Note: in case of these type of the data recovery if you want to courier the device to the customer. in safe side do not courier Original device to the customer. because if in transit original device is lost /Damaged then ……? always ask to the customer to arrange another working device for copy the data to send him or ask customer to pick up the device after testing it at your place so that your responsibility is over.

    Good repair! These USB memory sticks are a great invention of our time. Just the many different Nand memory chips with matching controller chips and different pinconfigurations that already exist makes any repair uncertain.

    good job on the repair. when I get these memory sticks in the shop they are either bad usb port or bad soldering joints and most of the time they are repairable. if the repair is deeper than than that i just sent it back to the customer and not worry about it. thanks for sharing and have a blessed day
