On newer hard disks, you should check whether Native Command Queuing (NCQ) is to be found under Commands/features. Owners of an SSD especially can find out quickly whether they are running the current firmware version. The designation and firmware version number are always listed at the top under Model Number and Firmware Revision. The information that hdparm delivers is dependent on the device. USB-to-IDE adapters often cause problems because they do not transmit the (complete) ATA or ATAPI commands to the drive. Hdparm accepts any device as mass storage that is connected to an (E)IDE, SATA, or SAS interface, including, therefore, DVD drives and SSDs. The | more option makes sure the large amount of information does not simply rush unread through the terminal. The tool will deliver all available data about the chosen drive – in this case, the first hard disk sda. Additional explanatory information is output when the '-long' option is used (and still more if the '-long' option is used twice).Figure 1: Hdparm lists the hardware properties of a six-year-old hard disk with a 320GB capacity. This utility's internal tables can be searched and output with the '-enumerate' option. Rather than try and document all of these here (or in the man page), another approach is taken. This utility currently contains over 500 entries spread across generic mode pages, transport specific mode pages, vendor specific mode pages, Vital Product Data (VPD) pages and their fields. Apart from SCSI disks, such devices include CD/DVD drives (irrespective of transport), SCSI and ATAPI tape drives and SCSI enclosures.Ī small set of commands associated with starting and stopping the media, loading and unloading removable media and some other housekeeping functions can also be sent with this utility. More generally sdparm can be used to access parameters on any device that uses a SCSI command set. When the SCSI device is a disk, sdparm's role is similar to its namesake: the Linux hdparm utility which is primarily designed for ATA disks that had device names starting with "hd". The sdparm utility accesses SCSI device parameters. Sdparm works as a command line application an it is used for getting and setting SCSI mode page fields. ![]()
