I'm getting the following error message when running hdparm -S on my external USB hard drive:



SG_IO: bad/missing sense data


Where is this sense data stored on the hard drive? I never encountered this error before, so I'm assuming something on the drive went corrupt.

  • @galoget That answer makes it seem it's a hardware issue ("drive controller doesn't support that method of enquiry, not all usb sata chipsets are created equal"). As I said in my question, hdparm -S worked before with the hard drive, but only now does it return the "SG_IO: bad/missing sense data". Did my hardware go bad?

hdparm is communicating with the driver controller firmware. It is requesting the sensor data from there. Here it might be that the controller/firmware does not support this command/operation or the tool is not the right for your controller/firmware.



If interested in more background information and details you may follow up at Linux SCSI Generic (sg) Driver, Python-SCSI or t10.org.

  • I did encounter the issue after upgrading my Linux kernel (I think to 4.14.14 or 4.14.15), so maybe it is the sg driver that changed.

The issue was that I needed to use:



sdparm -rs SCT=600 /dev/my_disk
sdparm -rC stop /dev/my_disk


instead of



hdparm -S 12 /dev/my_disk
hdparm -y /dev/my_disk


respectively.

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers.
