I'm using:
- Raspberry PI 4
- OS: Ububtu Server 20.04
- SSD: Kingston A400 SSD SA400S37/240G 2.5" SATA, 240 GB
- Cable: Sabrent USB 3.0 to SSD / 2.5-Inch SATA I/II/III Hard Drive Adapter (EC-SSHD)
- Power Cable: Default RPI Power Cable The external disk is powered by the RPI.
The disk can be mounted, used and it works fine.
When I try to transfer large (500MB+) files from/to RPI with mac GUI, rsync or scp the disk fails.
When I try to mount it again (after reboot):
mount: /media/ssd: can't read superblock on /dev/sda.
After that the disk disappears from lsblk.
