What's in the Box
- Seagate Exos X24 24TB Enterprise Internal Hard Drive (ST24000NM002H)
Note: Additional cables (SATA data, SATA power) and mounting screws are typically not included and must be purchased separately.
Setup
1. Physical Installation
Before installation, ensure your system is powered off and unplugged. Handle the hard drive by its edges to avoid static discharge. Locate an available 3.5-inch drive bay in your desktop or server chassis.
- Carefully slide the hard drive into the drive bay until it clicks into place or aligns with the screw holes.
- Secure the drive using appropriate screws (typically four screws, two on each side) to prevent vibration.
- Connect a SATA data cable from the hard drive to an available SATA port on your motherboard or RAID controller.
- Connect a SATA power cable from your power supply unit (PSU) to the hard drive's power connector.

2. System Recognition and Formatting
After physical installation, power on your system. The operating system needs to recognize and prepare the new drive.
- Access your system's BIOS/UEFI settings to confirm the drive is detected. Ensure the SATA port is enabled.
- Boot into your operating system (Windows, Linux, macOS).
- For Windows: Open Disk Management (right-click Start, select Disk Management). You should see the new drive listed as "Unallocated Space". Right-click on the drive, select "Initialize Disk", choose GPT (GUID Partition Table) for drives larger than 2TB, then create a "New Simple Volume" and format it (NTFS is recommended for Windows).
- For Linux: Use tools like `fdisk`, `parted`, and `mkfs` to partition and format the drive.
- For macOS: Use Disk Utility to erase and format the drive.
Note: Formatting a drive will erase all data on it. Ensure you select the correct drive.
Operating the Hard Drive
Once installed and formatted, your Seagate Exos X24 hard drive is ready for use. It functions like any other internal storage device, providing high-capacity, high-performance storage for your data.
- Data Storage: Use the drive to store large datasets, applications, and media files. Its 24TB capacity is ideal for demanding enterprise applications and data archiving.
- Performance: The 7200 RPM rotational speed and 6GB/s SATA interface ensure fast data transfer rates and responsive access times, suitable for data-intensive workloads.
- 24/7 Operation: Designed for continuous operation in server and data center environments, ensuring consistent performance and reliability around the clock.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your hard drive.
- Regular Backups: Always maintain regular backups of critical data. While the Exos X24 is highly reliable, no storage device is immune to failure.
- Monitor Drive Health: Utilize S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) tools to monitor the drive's health status. Many operating systems and third-party utilities offer this functionality.
- Proper Shutdown: Always shut down your system properly to prevent data corruption and mechanical stress on the drive. Avoid sudden power loss.
- Environmental Control: Ensure the operating environment maintains appropriate temperature and humidity levels, as specified in the product's technical documentation, to prevent overheating and condensation.

Troubleshooting
If you encounter issues with your Seagate Exos X24 hard drive, consider the following common troubleshooting steps:
- Drive Not Detected:
- Check all cable connections (SATA data and power) to ensure they are secure.
- Verify the SATA port is enabled in your system's BIOS/UEFI settings.
- Test the drive in a different SATA port or with different cables if possible.
- Ensure your operating system's Disk Management (Windows) or Disk Utility (macOS/Linux) recognizes the drive, even if unformatted.
- Slow Performance:
- Check for background processes consuming disk resources.
- Ensure the drive is not excessively fragmented (for HDDs, defragmentation can improve performance).
- Verify that your SATA controller drivers are up to date.
- Monitor drive temperature; overheating can lead to performance throttling.
- Unusual Noises:
- A clicking, grinding, or loud humming sound can indicate a potential drive failure. Immediately back up any accessible data and consider replacing the drive.
- Some enterprise drives may produce more audible operational sounds than consumer drives due to their design for high performance and reliability in server environments.
- Data Loss:
- If data becomes inaccessible, avoid further operations on the drive to prevent overwriting.
- Seagate Exos drives often include Seagate Rescue Data Recovery Services. Refer to the warranty section or Seagate's official website for details on how to utilize this service.
