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.

(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.
