1) I spoke to a hard drive specialist and he said that the BIOS of 2.5" and 3.5" HDDs is recorded on these memory chips but I don't know what type of memory and retention time
the models:
The 8pins (4 pins on each sides) with 25P05VP、25P10VP、25F512、25F1024、25F1024AN、SST25VF512、SST25VF010, etc. are the BIOS.
2) Are the firmware and Smart of 2.5" and 3.5" HDDs stored on another chip on the PCB? What type of chip?
