How do I read and write the original NTFS data disk after the Windows operating system is reinstalled to Linux?
Windows employs two major file systems, NTFS or FAT32, while EXT is the file system for Linux. When an operating system is changed from Windows to Linux after reinstallation, the data disk remains in its original format. Therefore, the system might be unable to access data disk’s file system. In these cases, you will need to use a format converter to read the data disk. For details, see Reading/Writing NTFS Data Disks after Reinstalling a Windows CVM to Linux CVM.

What are the differences among Premium Cloud Storage, SDD and Enhanced SSD?
Premium Cloud Storage: Tencent Cloud Premium Cloud Storage is a hybrid storage type. It adopts the Cache mechanism to provide a high-performance SSD-like storage, and employs a three-copy distributed mechanism to ensure data reliability. Premium Cloud Storage is suitable for small and medium applications with high requirements for data reliability and standard requirements for performance.
SSD: SSD uses NVMe SSD as the storage media, and employs a three-copy distributed mechanism. It provides high-performance storage with low latency, high random IOPS, high throughput I/O, and data security up to 99.9999999%, making it suitable for applications with high requirements for I/O performance.
Enhanced SSD: Enhanced SSD is based on Tencent Cloud’s latest storage engine, NVMe SSD storage media and the latest network infrastructure. It employs a three-copy distributed mechanism to provide high-performance storage with low latency, high random IOPS, high throughput I/O, and data security up to 99.9999999%, making it suitable for I/O-intensive applications with high requirements for latency, such as large databases and NoSQL.
Pricing of the three types of cloud disks varies with region. You can select the cloud disk that best suits your application requirements and budget. For pricing details, see Price Overview.
