This is two common disk interfaces on PCs, IDE (parallel hard drive) and SATA. Currently, the mainstream is SATA interfaces (serial hard drive, which is the trend of PC hard drive in the future.
Generally, the host has two IDE interfaces (IDE1 and IDE2), which are connected to four IDE devices. the main channel of the IDE disk is hda, the slave disk is hdb, and the master disk of the slave channel is hdc, the slave disk is hdd.
The name of the SATA disk device is/dev/sd [a-p].
You can check your hard disk usage:
[Phpddt.com @ localhost ~] $ Df-hl
Filesystem Size Used Avail Use % Mounted on
/Dev/sda2 18G 2.3G 15G 14%/
Tmpfs 504 M 84 K 504 M 1%/dev/shm
/Dev/sda1 291 M 32 M 245 M 12%/boot
Sda1 indicates the first partition of the first hard disk. in Linux, sda1 to sda4 can be the primary partition, and hda5 is the logical partition.
After work, I will summarize it next time and leave...
