Seagate IronWolf 125 support

[Mert]

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.

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)?

[Mert (hatrez)]

I cannot verify if this an issue caused by the Pi platform or not.
The only ARM computer I own is a Raspberry Pi 4 Model B.

I am running "Ubuntu 20.04.3 LTS aarch64" with following kernel version:
5.4.0-1044-raspi

Please send the kernel logs. And you haven't answered one of my questions: Is this SSD powered via USB? Because that could be a cause of your issues and is not recommended.
