While modern systems mostly use SATA and NVMe drives, forensic investigators often encounter legacy storage devices like PATA (IDE) drives in older computers and servers. These drives may hold critical digital evidence in cases involving corporate fraud, archival data, or even cybercrime investigations.
The Tableau TX1 Forensic Imager, a powerful and versatile tool, supports both modern and legacy interfaces, including PATA/IDE. This makes it invaluable for extracting forensic images while ensuring write-block protection and evidence integrity.
This blog will explain what a PATA drive is, how to identify it, its types, and the steps to safely create a forensic image using the Tableau TX1.
A PATA (Parallel ATA) drive, also known as an IDE (Integrated Drive Electronics) drive, is a legacy hard disk technology that was widely used before the introduction of SATA. It transfers data in parallel (multiple bits simultaneously) rather than serially, making it slower and bulkier compared to modern drives.
Key points about PATA drives:
Introduced in the 1980s and phased out by the mid-2000s.
Uses a 40-pin ribbon cable for data transfer.
Requires a separate 4-pin Molex connector for power.
Typically found in older desktops, servers, and legacy systems.
To identify a PATA drive, look for:
Data Connector: A wide 40-pin connector with a flat ribbon cable (older models may use 44 pins in laptops).
Power Connector: A 4-pin Molex power connector.
Jumper Pins: Small pins on the back to configure settings like Master, Slave, or Cable Select (CS).
Physical Size: Usually 3.5-inch drives for desktops and 2.5-inch drives for older laptops.
PATA drives evolved with increasing data transfer rates:
ATA-33: Early version with 33 MB/s transfer speed.
ATA-66 / ATA-100 / ATA-133: Faster generations with higher speeds.
2.5-inch IDE Drives: Compact versions found in older laptops.
3.5-inch IDE Drives: Larger desktop drives, most commonly encountered in forensic cases.
The Tableau TX1 is an industry-standard forensic imaging device supporting SATA, PATA/IDE, USB, SAS, PCIe, and NVMe interfaces. It ensures that data is acquired in a write-blocked manner, meaning the original evidence is never altered during acquisition.
Gather the Cables:
A 40-pin IDE ribbon cable.
A Molex power cable (provided with TX1 accessories).
Tableau TX1 IDE adapter, if required.
Set Jumper Settings:
Ensure the PATA drive is set to Master or Cable Select (CS), depending on how you connect it.
Connect the Data Cable:
Plug the 40-pin ribbon cable into the IDE port on the TX1 and the drive.
Connect the Power Cable:
Attach the 4-pin Molex power cable from the TX1 power supply to the PATA drive.
Power On TX1:
Once all connections are secure, power on the TX1.
The drive should be automatically detected and listed on the TX1 screen.
Select Source Drive:
From the TX1 interface, choose the connected PATA drive as the source.
Set Destination Drive or Storage:
Connect a SATA, USB, or network storage drive as the destination.
Choose Imaging Format:
TX1 supports E01 (EnCase Evidence File), Ex01, and RAW (DD) formats.
Select the one suitable for your investigation.
Configure Imaging Options:
Enable hashing (MD5, SHA-1, or SHA-256) for authentication.
Set compression level if using E01/Ex01.
Start Imaging:
TX1 will create a forensic image while ensuring the original PATA drive is not modified.
Verify Integrity:
Once the imaging process is complete, the TX1 verifies the hash values to confirm evidence integrity.
Legacy Support: Handles older drives still found in evidence.
Write-Blocking: Ensures forensic soundness of the process.
Multi-Interface Support: Works with IDE, SATA, SAS, NVMe, and more.
Automated Hashing: Provides authenticity for court admissibility.
Although PATA (IDE) drives are rare in today’s world, forensic investigators still encounter them in legacy systems, archives, or cold cases. Using the Tableau TX1 Forensic Imager, experts can safely acquire data from these drives while preserving evidence integrity.
By understanding how to identify, connect, and image a PATA drive, forensic professionals can unlock valuable digital evidence—even from decades-old hardware.
