introduced. Compared with FAT16, FAT32 mainly has the following characteristics:
1. The biggest advantage of FAT32 compared to FAT16 is that the disk size that can be supported is 2TB (2047GB), but partitions less than 512MB are not supported. Win 2000, based on FAT32, can support a maximum of 32GB partitions, while the FAT16 win 2000 supports a maximum of 4GB.
2. With smaller clusters, the FAT32 file system can save information more efficiently. I

One obvious change is that the VHDX size has increased from 2TB to 64TB, and can receive huge virtual machines and data resources. This can make the virtual disk more suitable for applications such as database or memory analysis.Even with carefully designed redundancy, batteries, and backup power supplies, acci

start with a match between the BIOS and the hard disk partition format, a simple summary is:* Uefi needs to be paired with GPT partition format* BIOS needs to match MBR partition formatUEFI Boot Mode2, UEFI, BIOS, GPT, mbr four differences1) Uefi and BIOSBoth UEFI and BIOS are part of the motherboard interface, and the UEFI is an upgraded version of the BIOS, which appears to replace the traditional BIOS. There are two advantages, one is to allow manufacturers to design the interface to play mo
MBR partition table
The traditional partitioning scheme, called the MBR partitioning scheme, is to save the partition information to 64 bytes in the first sector of the disk (the MBR sector). Each partition entry occupies 16 bytes, which contains the activity status flag, the file system identity, the start and end cylinder number, the number of magnets, the sector area code, and the hidden sector numbers ( 4 bytes), the number of total partition sectors (4 bytes), and so on. Because the MBR se

Since the MyISAM storage engine was used in MySQL 3.23, the maximum table size was increased to 65536TB (2567 – 1 bytes). Due to the larger table size allowed, the maximum valid table size for MySQL database is usually determined by the operating system's limit on file size, rather than the MySQL internal limit.
