When we use smartctl -C -t long /dev/sdX, the ATA SMART command we send has the usual 20s timeout. This is not enough, the drive usually needs several minutes for the test to complete.

On the command line: smartctl -C -t long /dev/sda

The command times out after 20s. Instead, the command should have a 10 + x minutes timeout, to be sure the device can complete the command before the error handler kicks in. We do know the test will last 10 minutes from SMART data information.

However, looking at the code it seems there is no way today to pass the desired timeout with an ATA passthrough command.

I would like adding the following memory device reference in drivedb:
