Operating the Hard Drive
After physical installation, the hard drive needs to be initialized and formatted by your operating system before it can be used for storage.
Initialization and Formatting (Windows):
- Access Disk Management: Right-click on the Start button (or press Windows Key + X) and select "Disk Management".
- Initialize Disk: A dialog box may automatically appear prompting you to initialize the new disk. If not, locate the new disk (it will likely be marked as "Unknown" or "Not Initialized"), right-click on it, and select "Initialize Disk". Choose MBR (Master Boot Record) for drives up to 2TB or GPT (GUID Partition Table) for drives larger than 2TB (recommended for 28TB). Click OK.
- Create New Simple Volume: Right-click on the "Unallocated" space of the initialized disk and select "New Simple Volume".
- Follow the Wizard: The New Simple Volume Wizard will guide you through the process.
- Assign the volume size (usually the maximum available).
- Assign a drive letter.
- Format the partition: Choose a file system (NTFS is standard for Windows), allocate unit size (default is usually fine), and give the volume a label (e.g., "Seagate 28TB"). Perform a quick format.
- Complete: Click "Finish" to complete the formatting process. Your drive will now appear in "This PC" (or "My Computer") and be ready for use.
Initialization and Formatting (macOS):
- Access Disk Utility: Open Finder, go to Applications > Utilities > Disk Utility.
- Select the Drive: In the sidebar, select your new Seagate drive (it will likely be listed under "External" or "Internal" drives).
- Erase the Drive: Click the "Erase" button in the toolbar.
- Configure Format:
- Name: Enter a name for the drive (e.g., "Seagate 28TB").
- Format: Choose a format. APFS is recommended for macOS 10.13 or later. Mac OS Extended (Journaled) is suitable for older macOS versions or if you need compatibility with certain applications.
- Scheme: Select "GUID Partition Map".
- Erase: Click "Erase" again to confirm. The drive will be formatted and mounted, ready for use.
