How to attach a linux Hard Disk

We should all know how to attach a linux hard disk. in Linux, there is no such concept as C or D, and some have only directories. Everything is based on directories. The root directory (/) is the most basic directory. There can be many directories below. The root directory can be loaded into a hard disk partition. Any directory below can also be loaded into another hard disk partition, this is also a convenient tool for Linux directory structure/hard disk management. Linux's hard disk representation is usually/dev/sd (x)/dev/hd (x ).... the above x represents a/B/c/d/e /..., this indicates the number of hard disks and then partitions, for example,/dev/sda (x). Here, x is a number, for example, 1/2/3/4/5 /..., here is the partition number. For example, if I want to add a new hard disk, I can use fidks-l to view it after I connect it to the system, check which name is used, for example,/dev/sdb. If the partition is ready and formatted now (if not, use the fisk partition) for example,/dev/sdb1 is the first partition and I want to load it into the/home directory, how to operate mount/dev/sdb1/home and execute the above line to be added to the system to start automatic loading, as long as it is added to/etc/fstab, the following/dev/sdb1/www ext3 defaults 1 2 is complete. In wdcp, the default software is installed in the/www directory, sometimes, if the root directory is not enough or is installed on another partition, you can load the new partition to the/www directory. As mentioned above, you can change/home to/www.
