Have you ever tried to partition a hard disk larger than 2TB using FDISK and wondered why you would get a warning to use GPT? Yes, you see that right. We cannot partition a hard disk larger than 2TB using FDISK.In this case, we ca
If the disk size exceeds 2TB, you can use the parted command to create the partition.
We first mount a 4TB disk:
Partition partitioning using the parted tool:
Note that we use Mklabel GPT to modify the disk partition format to GPT format, which is MBR format by default. If no modification is made, only 2.2TB
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 sec

Hard disk Partitioning principle three: Use NTFS partition except C disk
Reason: NTFS file system is a security and reliability based file system, in addition to compatibility, it is far superior to FAT32. Not only can it support partitions up to 2TB in size, but it also supports compress
disk space, the base unit is not a byte but a cluster. The size of the cluster is related to disk specifications, in general, the number of slices per cluster of the hard disk may be 4, 8, 16, 32, 64 ... Typically three file systems are used under the Windows platform for fat (file partition tables), FAT32 (32-bit fil

If you have installed the initial information for the Windows,windows boot loader in this area-if the MBR information is overwritten causing Windows to not start, you will need to use the MBR Repair feature of Windows to get it back to normal. If you have Linux installed, it will usually be the grub loader in the MBR. The MBR supports a
The number of surveillance cameras that need to be recorded, such as 6 cameras needed to save video, is 6.
Calculation method:
Single-day Video size = main stream (M) ÷8x3600 (sec) x24 (hour) x channel number ÷1024
Video days = hard disk Capacity (G) x1024x coefficient x8÷3600 (seconds) ÷24 (time) main stream (M) Number of channels
such as: 1 1080P camera, 4M main stream of the day video size: 4÷8X360
Now the computer hard disk capacity has reached 1TB, 2TB such a huge space, for our work and life has brought greater convenience, many people will drive more partitions, the hard disk capacity to fully use up.The operation of the partition is believed that many people will,
