This article will combine the hot content of the entire network in the past 10 days, analyze the common reasons for hard disk partition failure, and provide structured data and solutions.
1. Common reasons for hard disk partition failure
| Cause classification | Specific performance | frequency of occurrence |
|---|---|---|
| Hard drive damaged | Bad sectors, physical damage | 35% |
| System permissions issue | Insufficient administrator rights | 25% |
| Partition table error | MBR/GPT damaged | 20% |
| software conflict | Third-party partitioning tools are not compatible | 15% |
| other reasons | Driver problems, viruses, etc. | 5% |
2. Comparison of popular solutions
| solution | Applicable scenarios | success rate | Operation difficulty |
|---|---|---|---|
| Repair using DiskGenius | Partition table is damaged | 85% | medium |
| CMD command fix | Permissions issue | 70% | Simple |
| Replace data cable/interface | connection problem | 60% | Simple |
| low level formatting | Severe bad sectors | 50% | complex |
3. Specific solutions to partition failure
1.Check hard drive connection status: First confirm whether the hard disk is connected correctly. You can try to replace the data cable or interface. Many users report that this is the most overlooked but most common cause of problems.
2.Use disk management tools: The disk management tool that comes with Windows is the preferred solution. Right-click "This PC" - "Manage" - "Disk Management" to check the hard disk status and try to partition.
3.Repair partition table: If "Partition Table Error" is prompted, you can use DiskGenius or other professional tools to repair it. This is the most discussed solution in the forum in the past 10 days.
4.Convert to GPT format: For large-capacity hard drives (more than 2TB), the GPT partition format must be used. Conversion can be performed via the diskpart command:
• Open CMD (administrator rights)
• Enter diskpart
• Enter list disk
• Enter select disk X (X is the target disk number)
• Type clean
• Enter convert gpt
4. Sharing of recent hot cases
| Case type | Problem description | solution |
|---|---|---|
| New hard drive cannot be partitioned | The newly purchased 4TB hard drive is displayed as read-only in Windows | Convert to GPT format |
| Partition disappears suddenly | The hard disk partition in use suddenly cannot be recognized | Use TestDisk to restore partition table |
| Partition size limit | Unable to create partition larger than 2TB | Use GPT partition format |
5. Preventive measures
1. Back up important data regularly to prevent data loss caused by partition failure.
2. Use reliable power supplies and interfaces to avoid partition problems caused by insufficient power supply.
3. Before partitioning a new hard disk, check the SMART status to ensure the health of the hard disk.
4. Avoid sudden power outage or forced shutdown during the partitioning process.
6. Professional advice
If you still can't solve the problem after trying the above methods, it is recommended to:
• Contact the hard drive manufacturer for technical support
• Seek professional data recovery services
• Consider replacing hard drives (especially older ones)
Recent heated discussions in the technology community indicate that with the increase in hard drive capacity and the application of new technologies, partitioning issues have become more complex. Only by mastering the correct knowledge about partitioning and how to use tools can you effectively avoid the trouble of "why the hard disk cannot be partitioned".
