World's #1 choice for GC analysis

Buy a wax-based composite repair stick that matches your specific Trex color (e.g., Spiced Rum, Tiki Torch, Gravel Path).

The T-Rex WD repair tool offers several benefits, including:

In the hierarchy of hard drive repair software, TREX sits at the very top. It is not a standard data recovery program like Recuva or EaseUS; rather, it is a direct descendant of the internal diagnostic software developed by Western Digital (WD) itself or reverse-engineered to mimic factory-level operations. Within the Chinese repair community, TREX is widely accepted as the foundation upon which most modern WD repair tools are built.

Using the T-Rex WD repair tool is relatively straightforward. Here's a step-by-step guide:

The T-Rex WD Repair Tool uses a proprietary process to diagnose and repair water-damaged devices. The process involves several stages:

Files typically become corrupted when the recording process is abruptly stopped before the file header can be properly written. Common triggers include:

A notable aspect of TREX usage is the "Hotswap" technique. Many WD drives that are "blacklisted" or "locked" by firmware can be difficult to access. Advanced technicians use the reset (soft reset) and ireset (hard reset with power cycle) commands to force the drive into an accessible mode without destroying the physical PCB. This technique is crucial for drives stuck in the busy state.

The firmware controls everything: bad block management (P-List and G-List), SMART attributes, logical-to-physical address translation, error correction, and even the drive's behavioral responses to ATA commands. When a drive fails, it is often not a physical calamity (like a head crash) but a or a logical issue within the SA. Examples include:

Allows users to view clips before initiating the full export process.

This is TREX's primary strength. Using commands like rd (read module), wr (write module), mod , dir , and sa , the user can:

Hard drive failure is a stressful experience, particularly when it involves Western Digital (WD) drives, which are widely used for both personal and enterprise storage. When a WD drive exhibits symptoms like clicking, spinning down, or failing to be recognized by the operating system, it often points to a rather than a purely physical issue.

For firmware or controller hangs, select the module.

How it works?

Java GC Tuning is made to appear as rocket science, but it's a common sense!

  • 1

    Enable GC Logs

    You can enable GC log by passing following JVM arguments:
    Until Java 8: -XX:+PrintGCDetails -Xloggc:<GC-log-file-path>
    Java 9 & above: -Xlog:gc*:file=<gc-log-file-path>

How to enable Java GC Logging?

For Java 1.4, 5, 6, 7, 8 pass this JVM argument to your application: -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:<file-path>

For Java 9, pass the JVM argument: -Xlog:gc*:file=<file-path>
file-path: is the location where GC log file will be written

GCeasy couldn't parse my GC Logs?

We do support all of the GC log formats irrespective of the JVM version, JVM provider, GC algorithms, memory settings.

However if we don't support your format, Please report it to . We will fix it.

Can I look at sample GC log analysis reports?

Sure. Here are some sample reports generated by GCeasy:
