How to view the HDD/SSD
1. Check USB device
pi@raspberrypi:~ $ lsusb Bus 002 Device 004: ID 152d:0561 JMicron Technology Corp. / JMicron USA Technology Corp. JMS551 - Sharkoon SATA QuickPort Duo Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 046d:c52b Logitech, Inc. Unifying Receiver Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
The first line indicates that the USB device has been correctly recognized by the OS.
If you cannot find the corresponding USB device, please check that your USB device is tightly connected, or replug the USB3 connector, or replace the USB3 connector with a USB-A to USB-A cable.
Sometimes, insufficient power supply may also cause the USB device not to be found, so we can also try to replace a high-quality power adapter.
If you have tried these actions and still cannot solve the problem, please contact us （support@geekworm.com） with the result information after running the lusb command and your order number.
2. View HDD/SSD
pi@raspberrypi:~ $ fdisk -l fdisk: cannot open /dev/ram0: Permission denied fdisk: cannot open /dev/ram1: Permission denied fdisk: cannot open /dev/ram2: Permission denied fdisk: cannot open /dev/ram3: Permission denied fdisk: cannot open /dev/ram4: Permission denied fdisk: cannot open /dev/ram5: Permission denied fdisk: cannot open /dev/ram6: Permission denied fdisk: cannot open /dev/ram7: Permission denied fdisk: cannot open /dev/ram8: Permission denied fdisk: cannot open /dev/ram9: Permission denied fdisk: cannot open /dev/ram10: Permission denied fdisk: cannot open /dev/ram11: Permission denied fdisk: cannot open /dev/ram12: Permission denied fdisk: cannot open /dev/ram13: Permission denied fdisk: cannot open /dev/ram14: Permission denied fdisk: cannot open /dev/ram15: Permission denied fdisk: cannot open /dev/mmcblk0: Permission denied fdisk: cannot open /dev/sda: Permission denied fdisk: cannot open /dev/sdb: Permission denied
The last two lines indicate that 2 SSDs devices were found. (/dev/sda and /dev/sdb)
3. Check if the hard disk is partitioned.
pi@raspberrypi:~ $ sudo fdisk /dev/sda Welcome to fdisk (util-linux 2.36.1). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Command (m for help): p Disk /dev/sda: 74.53 GiB, 80026361856 bytes, 156301488 sectors Disk model: Tech Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 4096 bytes / 33553920 bytes Disklabel type: dos Disk identifier: 0x65b1c901 Device Boot Start End Sectors Size Id Type /dev/sda1 65535 156301487 156235953 74.5G 83 Linux Partition 1 does not start on physical sector boundary. Command (m for help):
The above result tells us that SDA already has a partition: /dev/sda1
pi@raspberrypi:~ $ sudo fdisk /dev/sda Welcome to fdisk (util-linux 2.36.1). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Command (m for help): p Disk /dev/sda: 74.53 GiB, 80026361856 bytes, 156301488 sectors Disk model: Tech Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 4096 bytes / 33553920 bytes Disklabel type: dos Disk identifier: 0x65b1c901 Command (m for help):
The above result tells us that SDA has no partitions
If the hard disk is not partitioned, we need to partition the hard disk

The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.
Note: If you need to support partitions larger than 2TB, you need to use the parted command
How to format HDD/SSD
pi@raspberrypi:~ $ sudo mkfs.ext4 /dev/sda1 mke2fs 1.46.2 (28-Feb-2021) /dev/sda1 alignment is offset by 512 bytes. This may result in very poor performance, (re)-partitioning suggested. Creating filesystem with 19529494 4k blocks and 4882432 inodes Filesystem UUID: dc0c2c55-145e-440d-a648-c4909b13c021 Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424 Allocating group tables: done Writing inode tables: done Creating journal (131072 blocks): done Writing superblocks and filesystem accounting information: done
'/dev/sda1'/ is the first partition of the SDA . If you divide SDA into multiple partitions, there may be /dev/sda2, /dev/sda3, etc.
