Thanks rdave13! I just opened up the program called DiskInfo.exe and it just started. No install required. :)
So the program states that the transfer mode..... Transfer Mode : SATA/300 | SATA/300. One value is the current transfer mode and the other is the supported transfer mode. Is the supported transfer mode stating all possible transfer modes that the laptop excluding the HDD is capable of supporting? Or is it just stating the transfer modes that are currently supported with the current setup including the HDD?
