.HDDChecker is a basic disk diagnostic tool meant for testing the health of your PlayStation 2 console's Harddisk Drive unit.It has the following features:. Detects and lists the model, serial, firmware and S.M.A.R.T. Status of HDD unit 0 (Primary Master). Performs a surface scan of the disk. Supports 48-bit LBA disks up to 2TB. Performs zero-filling of the disk with large blocks.
With the surface scan, bad sectors found might be remappable. Based on my research, it appears that writing to a to-be-remapped sector (those hard-to-read sectors, as recorded by the disk) will kick off the actual sector remapping process.
