DIY Hard Drive Diagnostics: Understanding a Broken Drive

< Link to the Speech Slides > PDF: Big – 39 Megs

How to know what’s wrong with your hard drive

Let’s think about the problem first, let’s listen to the sounds before we disassemble a drive

Stop and think about the problem first, do not take the lid off

It could be a Firmware, Head, Board, Motor or Platter problem.

Seagate and Western Digital have exceptions: replacing the head or known firmware problems

Five Phases of Data Recovery

1) Diagnostic Copying/Imaging the drive

2) Repair Repair the drive, requires hardware or special equipment

3) Image Image, Copy or Recover the physical drive

4) Recovery Perform Logical Recovery of files

5) Repair Repair files or partitions, re-assemble data

Absolutely do not ever run any utilities on the original drive until you image it

CheckDisk, FIXMBR, FIXBOOT, say no to SpinRite (it writes data to the same drive, instead of a destination drive)

Media Tools Pro Data recovery and forensic tool

Do not use USB connectors

It is a dumb connector, it doesn’t handle ATA commands, cannot handle errors very well,

Connect a drive directly to a motherboard instead.

Includes MHDD which is the most popular freeware application for low-level HDD diagnostics.
