3.3 Initializing Hard Drives (for new drives or drives over 2TB)
For new hard drives, or existing drives larger than 2TB, proper initialization is crucial:
- For drives over 2TB: It is highly recommended to initialize these drives using the GPT (GUID skaidinių lentelė) partitioning scheme. MBR (Master Boot Record) partitioning is limited to 2TB and may cause data loss or recognition issues with larger drives.
- Access your operating system's disk management tool (e.g., Disk Management in Windows, Disk Utility in macOS) to initialize and format your drives.
