Is this a problem specific to the Pi platform or ARM in general? Is the SSD self-powered via USB or externally powered?
Also, you logged this against linux-raspi2 which seems wrong since it doesn't support the Pi 4. Which release and kernel are you running (lsb_release -a, uname -a)? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi2 in Ubuntu. https://bugs.launchpad.net/bugs/1947925 Title: Seagate IronWolf 125 support Status in linux-raspi2 package in Ubuntu: New Bug description: This is not a severe bug. (Lack of Firmware for linux on arm) Seagate's SSD IronWolf 125 (1TB) doesn't work reliable on the raspberry pi 4 (connected via SATA3 to USB, (Tried out multiple SATA3 to USB Cables)). After the internal ssds cache is filled the ssd will be locked and is not accessible anymore. FDISK will no longer list the SSD anymore. The SSD is brand new and is working fine on Mac and Windows. It also works fine on Linux (x86). But Linux on arm will fail on this ssd. I looked up on their official site to download the firmware but there is actually no firmware to download. I once downloaded the ssd support program on windows to check its integrity => no hardware errors.
