SATA Hard Drive Cables

Connectors and cables present the most visible differences between SATA and parallel ATA drives. Unlike PATA, the same connectors are used on 3.5-inch SATA hard disks for desktop and server computers and 2.5-inch disks for portable or small computers; this allows 2.5-inch drives to be used in desktop computers with only a mounting bracket and no wiring adapter. Smaller disks may use the mini-SATA spec, suitable for small-form-factor Serial ATA drives and mini SSDs.

There is a special connector (eSATA) specified for external devices, and an optionally implemented provision for clips to hold internal connectors firmly in place. SATA drives may be plugged into SAS controllers and communicate on the same physical cable as native SAS disks, but SATA controllers…

File System Forensic Analysis

file system forensic analysis This is an advanced cookbook and reference guide for digital forensic practitioners. File System Forensic Analysis focuses on the file system and disk. The file system of a computer is where most files are stored and where most evidence is found; it also the most technically challenging part of forensic analysis. This book offers an overview and detailed knowledge of the file system and disc layout. The overview will allow an investigator to more easily find evidence, recover deleted data, and validate his tools. The cookbook section will show how to use the many open source tools for analysis, many of which Brian Carrier has developed himself.

Coverage includes:

  • Preserving the digital crime scene and duplicating hard disks

The Purpose Of Computer Forensics

Computer Forensics Computer forensics is the branch of forensic science that examines evidence stored digitally on a hard drive or other data storage medium.

History

Computer forensics can be traced back to the beginning of the 1990s when computers began to be integrated into our daily existence. DIBS USA was one of the first computer forensics companies to emerge.

Function

Computer forensics is about the preservation and extraction of data. Data is often found in server logs or on suspects’ hard drives. Since every move on a computer leaves a footprint, forensic experts have to find out how to tie that footprint to a case.

Misconceptions

Computer forensics doesn’t involve a lot of high-level hacking or computer security knowledge since most…

What are the common Reasons of Hard Disk Drive failure?

What are the common Reasons of Hard Disk Drive failure?

1. Electronic Component Failure
2. Motor Failure
3. Read / Write Head Failure
4. Media Damage
5. Firmware Corruption
6. Logical Failure

One or all of the above primary causes may be evident when diagnosing a failed hard disk drive.

Electronic Component Failure

Electronic components may fail due to voltage transients, heat or poor handling. Substitution, repair and re-programming is generally required in order to recover data stored on the hard disk. PCB assemblies are however hyper tuned at the manufacture stage and specialist re-programming and calibration is subsequently required to restore the hard disk to a working condition.

Motor Failure

Hard disk motor spindles…

Maxtor Firmware repair 2.0

Maxtor Firmware Repair 2.0 is a program  aiming at solution for typical firmware malfunction of Maxtor 541DX (2B020H1 2B010H1), which may manifest itself as follows:
