How do I have two disk drives? I have two HDs connected but only the HD where I downloaded UmbrelOS is showing up. How do I get them both to be recognized?
I have the same question, I installed Umbrel on the NVME but the PC has a 1 TB Sata drive also Id like to use for movies/etc.

To see what drives are in use and how to mount a drive in Linux, here are the steps:
1. Check Drives in Use
You can use several commands to list drives and their status:
-
lsblk
: Lists block devices, including drives, partitions, and mount points.lsblk
- Output shows devices (e.g.,
/dev/sda
,/dev/sdb
), their partitions, and mount points (if mounted). - Example:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 500G 0 disk ├─sda1 8:1 0 100G 0 part /home └─sda2 8:2 0 400G 0 part /data sdb 8:16 0 1T 0 disk
- Output shows devices (e.g.,
-
fdisk -l
: Lists all disk partitions (requires root privileges).sudo fdisk -l
- Shows all disks and partitions, including those not mounted.
- Example:
Disk /dev/sda: 500 GiB, 536870912000 bytes, 1048576000 sectors ... Device Boot Start End Sectors Size Id Type /dev/sda1 2048 209715200 209713153 100G 83 Linux
-
df -h
: Shows mounted drives and their usage.df -h
- Displays mounted filesystems, their size, used space, and mount points.
- Example:
Filesystem Size Used Avail Use% Mounted on /dev/sda1 100G 50G 45G 53% /home /dev/sda2 400G 200G 180G 53% /data
-
blkid
: Lists UUIDs and filesystem types of all devices.sudo blkid
- Example:
/dev/sda1: UUID="1234-5678" TYPE="ext4" /dev/sdb1: UUID="abcd-efgh" TYPE="ntfs"
- Example:
2. Mount a Drive
To mount a drive, follow these steps:
Step 1: Identify the Drive
Use lsblk
or blkid
to find the device name (e.g., /dev/sdb1
) and its filesystem type (e.g., ext4
, ntfs
, vfat
).
Step 2: Create a Mount Point
Create a directory where the drive will be mounted.
sudo mkdir /mnt/mydrive
Step 3: Mount the Drive
Use the mount
command to mount the drive. Replace /dev/sdb1
with your device name and /mnt/mydrive
with your mount point.
sudo mount /dev/sdb1 /mnt/mydrive
- For specific filesystems, you may need additional options (e.g.,
uid=1000,gid=1000
for NTFS to set permissions).
Example for NTFS:sudo mount -t ntfs-3g /dev/sdb1 /mnt/mydrive
Step 4: Verify the Mount
Check if the drive is mounted:
df -h
or
lsblk
Step 5: Access the Drive
Navigate to the mount point to access files:
cd /mnt/mydrive
ls
3. Automount a Drive (Optional)
To mount a drive automatically on boot, edit /etc/fstab
:
-
Open
/etc/fstab
with a text editor:sudo nano /etc/fstab
-
Add an entry for your drive. Example for an
ext4
drive:UUID=1234-5678 /mnt/mydrive ext4 defaults 0 2
- Replace
1234-5678
with the UUID fromblkid
. - Replace
/mnt/mydrive
with your mount point. - Replace
ext4
with your filesystem type.
- Replace
-
Save and test the configuration:
sudo mount -a
Notes
- Unmounting: To unmount a drive:
sudo umount /mnt/mydrive
- Permissions: Ensure you have appropriate permissions for the mount point (
sudo chmod
orchown
if needed). - USB Drives: Many Linux distributions auto-mount USB drives under
/media/<username>/
. Check withlsblk
ordf -h
. - Errors: If mounting fails, check the filesystem type or repair the drive with
fsck
(e.g.,sudo fsck /dev/sdb1
).
If you need help with a specific drive or error, let me know!
