Maxtor Data Recovery Information

Maxtor hard drives are well-known for their firmware problems.
Firmware of the drive is not located on the PCB as most people may think. Main part of firmware is stored on the platter in so-called System Area. System Area occupies the negative cylinders, usually on the inner diameter and contains a number of firmware modules. These modules are like system files in Operating System - some of them are critical, others are just log files, all of them have different importance and functionality. If one of the modules becomes corrupted the whole hard drive micro-operating system can't boot up, the drive can't initialize correctly and stops working. There are SMART modules, Configuration modules, Security modules, Translator modules, Log modules and many others that belong to different subsystems of HDD OS. Translator subsystem is in charge of translating host-understandable LBA addressing into hard drive physical Cylinder-Head-Sector addressing. To do that translator uses a number of defects tables like G-List, P-List, Zone table, etc. These tables are updated constantly and therefore due to power surge or firmware bugs quite often get corrupted. If this situation occurs the drive becomes identified with its factory alias(N40P, Calypso, Sabre etc) instead of its model name(6E040L0, 6Y120P0 for example) and shows up with 0 capacity. If you attempt to boot up from that drive or read any data from it you would get "Primary Master Hard Disk Fail" error or something like this.

Currently there is no way to DIY this type of problem at home. It is quite a complicated job and requires special expensive equipment and deep knowledge of hard drive design and data recovery technology. Luckily, it doesn't usually require opening the HDD in clean room and ordering donor drives, so data recovery in this case shouldn't be too pricey.

Another issue with Maxtor hard drives is damage to the components on the cirquit board(PCB). Maxtor drives are very vulnerable to overheating, power surges and bad power supply unit combined with power streak is usually enough to burn spindle driver(usually SMOOTH L2750 chip on the PCB. If this occurs the computer would reboot itself, you would normally notice acrid smoke coming from your PC and upon power on the drive would not spin up at all.

Another quite common symptom Maxtor drives have is clicking or knocking sound. The drive spins up and the head starts clicking right away with a regular constant sound(click to listen). Most often this a sign of a bad head, but before doing any clean room work, it is very important to perform accurate diagnostics and eliminate a chance of possible firmware corruption that sometimes can also cause clicking.

There is one more problem that is typical for all Maxtor drives: bad sectors. After some period of time magnetic media that covers the platters starts to degrade and magnetic domains can't be turned in a desired direction by writing element of the head. This is how bad sectors appear.
When the drive starts reading data from such unreadable bad sector it could start freezing, scratching and sometimes even clicking. This leads to further damage to the heads and surface, and may result in further data loss. As soon as you start experiencing such symptoms stop the drive immediately and send it to our data recovery lab for evaluation. Any further attempts would just add up to the problems. In our lab we use special imaging hardware tools that are capable of reading raw sector data ignoring checksum check. That's usually the only way to get as much data as possible from these sectors.
