Initialise Disk

Possible Reasons:​

1. Incorrect Partition Information:
   • The drive might have incorrect or corrupted partition information. This can sometimes cause the size to be displayed incorrectly.
2. Unallocated Space:
   • Part of the drive might not be formatted or allocated, leaving part of its capacity unused and hidden in disk management.
3. Different Drive:
   • There’s always a chance this isn’t your 10TB drive, especially if you have multiple storage disks.
4. Failure or Corruption:
   • If the drive has developed faults or corruption, it could behave unpredictably and display an inaccurate capacity.
5. MBR vs. GPT Issue:
   • If the drive was initialized as an MBR disk, it’s limited to a maximum capacity of 2TB for a single partition. Drives larger than 2TB need to be initialized as GPT to access their full size.

What To Do:​

1. Check Disk Management:
   • Open Disk Management (Win + X > Disk Management).
   • Look for your drive. Ensure it’s listed with the correct capacity and check if any of its space is marked as Unallocated.
2. Verify Using Third-Party Tools:
   • Download tools like CrystalDiskInfo or EaseUS Partition Master to verify the actual size and health of the drive. These programs often display more low-level details.
3. Check for GPT vs MBR Initialization:
   • In Disk Management, right-click the disk and look for the option labeled Convert to GPT Disk (if it’s MBR) or confirm it’s already GPT. Note: Converting to GPT may wipe the disk, so proceed cautiously.
4. Test for Corruption:
   • Run chkdsk on the drive via Command Prompt. Use the command:
     
     Code:

      chkdsk X: /f /r

     Replace X: with the drive letter. This checks for errors and attempts recovery.
5. Confirm Drive Details:
   • If you’re still unsure, double-check the physical label of the drive or the details in Device Manager (Win + X > Device Manager > Disk Drives).
