HddSurgery Tools For Western Digital Ramp Hard Drives

In our previous article we have shown video guides for using our head replacement tools for Western Digital CSS hard drives.

In this article we will present our head swap tools for Western Digital hard drives which park their heads on the ramp.HDDS WDC 2.5"-3.5" Ramp Set]HDDS WDC 2.5"-3.5" Ramp Set

This set of head replacement tools (Head Combs) can be used to replace heads on almost all 2.5" and 3.5" Western Digital hard drives which have their heads parked on a ramp. Set contains 7 pairs (14 pieces) of head replacement tools.

These head replacement tools are used to ensure that the heads do not touch each other in proces of replacement and to enable their easy mounting back to the ramp.

Our next article will show a presentation for Western Digital Ramp hard drives.

Quantifying Data Volatility for IoT Forensics With Examples From Contiki OS

Forensic Focus 22nd June 2022 5:00 am

File timestamps are used by forensics practitioners as a fundamental artifact. For example, the creation of user files can show traces of user activity, while system files, like configuration and log files, typically reveal when a program was run. 

Despite timestamps being ubiquitous, the understanding of their exact meaning is mostly overlooked in favor of fully-automated, correlation-based approaches. Existing work for practitioners aims at understanding Windows and is not directly applicable to Unix-like systems. 

In this paper, we review how each layer of the software stack (kernel, file system, libraries, application) influences MACB timestamps on Unix systems such as Linux, OpenBSD, FreeBSD and macOS.

We examine how POSIX specifies the timestamp behavior and propose a framework for automatically profiling OS kernels, user mode libraries and applications, including compliance checks against POSIX.

Our implementation covers four different operating systems, the GIO and Qt library, as well as several user mode applications and is released as open-source.

Based on 187 compliance tests and automated profiling covering common file operations, we found multiple unexpected and non-compliant behaviors, both on common operations and in edge cases.

Furthermore, we provide tables summarizing timestamp behavior aimed to be used by practitioners as a quick-reference.
