Flash Read Error, Flash Drive not recognized- How to repair USB flash drive

21 02 2008

Many times we see flash storage that is not recognized by the Operating System due to formattingflash drive not recognized problems, read errors, and lost file table information. Many times this is not a disaster, but rather an easily and quickly correctable data recovery issue that can be handled cheaply by a professional recovery shop.

If you feel you are up to the challenge you will need several things:

  1. Weller WP25 Soldering iron
  2. Weller ST7 Solder Iron Tip-Conical
  3. Soldering station with alligator clips. iron holder & magnifying glass
  4. putty knife or strong blade to cut into drive case
  5. some soldering skill

usb-repairPlease do not attempt this procedure if you cannot afford to lose all your data, leave this procedure to the professionals.

The first step is to 1-gently cut into the case, not touching any of the sensitive components inside (this is really a ONE-SHOT deal) if you screw them up, oh well, you saved money but lost all your data. 2-peel back the case, exposing the board and chipset. 3-identify the broken connectors, this is the trick, and you may need a higher powered dual-scope for this procedure. Resolder the connectors after identifying them. If this procedure does not work, you may need to remove the connector completely, and attach wires to the board that are tied to a new cable connector.
