Hi, my disk usage quota is full due to a virus/hack rather than my own files. This is because in a few days my 500GB quota has been maximized. I've SSH-ed into my root folder and tried to locate the extra files. I'm being told /dev/hda1 has 100% usage and is full. But when I try to navigate into it, I'm told it isn't a folder.

Has anyone had similar experiences like this? I don't have much background in this. Thanks in advance!

devices like /dev/sda or /dev/hda in dev are "block devices." They represent physical disks, so they are not normal files or folders. /dev/hda1 represents the first partition on the physical disk.

use a command such as "df -h" to see what folder or mount point places files on that. For example if I want to check space on /dev/sda1 I run "df -h" from a shell and I see this:

Filesystem  Size  Used Avail Use% Mounted on
/dev/sda1  440G  8.3G  410G  2%  /
/dev/sdc1  915G  96G  774G  11%  /home
So to free up space on that disk I would need to remove files under / (the root directory) that aren't assigned to other partitions. For example to free space on /dev/sdc1 I would have to remove files under /home.
