Disk Table Configuration
Columns
You can configure which columns are shown by the disk table widget by setting the columns setting:
[disk]
# Pick which columns you want to use in any order.
columns = ["Disk", "Mount", "Used", "Free", "Total", "Used%", "R/s", "W/s"]
Default Sort Order
You can customize the default sort order (by default, it sorts by disk name). For example, to sort by the read rate:
[disk]
default_sort = "R/s"
You can use any valid column name here (e.g. "Disk", "Mount", etc.). Note that if you put a column name that is not actually used, the default sort will just be the first column shown.
Show Unmounted Devices (Linux only)
By default, only mounted devices are shown. To also show unmounted devices on Linux, enable include_unmounted:
[disk]
include_unmounted = true
Unmounted devices show I/O activity but have no used/free space (those require a live mount), so those
columns appear as N/A. Pseudo-devices (loop*, ram*, zram*) are skipped, and you can hide other
noisy devices with the name filter.
Filtering Entries
You can filter out what entries to show by configuring [disk.name_filter] and [disk.mount_filter] to filter by name and mount point respectively. In particular,
you can set a list of things to filter with by setting list, and configure how that list
is processed with the other options.
For example, consider a disk widget showing these entries:

If we wanted to ignoring any entry with a name that matches /dev/sda:
[disk.name_filter]
# Whether to ignore any matches. Defaults to true.
is_list_ignored = true
# A list of filters to try and match.
list = ["/dev/sda"]
# Whether to use regex. Defaults to false.
regex = true
# Whether to be case-sensitive. Defaults to false.
case_sensitive = false
# Whether to require matching the whole word. Defaults to false.
whole_word = false
This would give us:

We can also combine both the name filter and mount filter. For example:
[disk.name_filter]
is_list_ignored = false
list = ["/dev/sda"]
regex = true
case_sensitive = false
whole_word = false
[disk.mount_filter]
is_list_ignored = true
list = ["/mnt/.*", "/"]
regex = true
case_sensitive = false
whole_word = true
This gives us:
