Hi, Neidson. Let's examine the possible causes for this discrepancy:
- Disk partitioning: The disk might have been partitioned in such a way that the 400MB partition is the only one currently visible to Disk Management, leaving the rest of the capacity unallocated.
- File system issues: The disk might have a corrupted file system or a file system that Windows doesn't recognize.
- Disk firmware or driver issues: Outdated or incompatible firmware/drivers might cause the disk to be reported incorrectly.
- Hardware issues: The disk itself, the SATA/USB cable, or the disk controller might be faulty.
To resolve this issue, follow these geeky steps:
1. Open Disk Management (diskmgmt.msc) and check for any unallocated space on your disk. If there's a large unallocated space, you can create a new partition or extend the existing partition to utilize the full capacity.
2. If you still can't see the correct capacity, you might need to check the disk's file system. To do this, open Command Prompt with Administrator privileges and type the following command:
chkdsk X: /f
Replace "X" with the drive letter of the affected disk. This command will scan and repair any file system errors.
3. If the issue persists, you can try updating your disk's firmware and drivers. Visit the manufacturer's website for the latest firmware and drivers, and follow their instructions to install them.
4. If none of the above steps work, consider using a different SATA/USB cable or disk controller to rule out any hardware issues. If the problem persists, your disk itself might be faulty, and you should contact the manufacturer for further assistance or consider
replacing the disk.
Remember to backup any important data before making changes to your disk, as some of these steps might result in data loss.
I hope it helps.
