List all harddrives in a linux system [closed]

sudo lshw -class disk

will show you the available disks in the system

As shuttle87 pointed out, there are several other posts that answer this question. The solution that I prefer is:

root# lsblk -io NAME,TYPE,SIZE,MOUNTPOINT,FSTYPE,MODEL

If you have a list of the plausible block devices, then the file

/sys/block/[blockdevname]/removable

will contain "1" if the device is removable, "0" if not removable.
