I just did this exact process a moment ago. ![]() but if I physically remove power from the hard drives SATA connection, wait a moment, plug it back in, then I see 'not frozen' and the secure erase procedure will work. hence, that did not work (at least not on this ASUS A8N32-SLI Deluxe motherboard). Which put it to sleep (you could hear stuff power down etc and green power LED on front of case is flashing etc), I waited about 10 seconds or so, pressed a button, and upon waking back up, 'sudo hdparm -I /dev/sdx' still shows 'frozen' instead of 'not frozen' on that same 2.5" HDD. then you just plug it back in a moment later and proceed with secure erase.Ĭode: Select all echo -n mem | sudo tee /sys/power/state so any movement pulling the plug would be that much less likely to damage anything since nothing is moving. "sudo hdparm -Y /dev/sdx" (you can actually hear the HDD power down after that command) which I figure makes things safer vs just pulling the power plug with the HDD running normally since after that command the hard drive is basically off. but when it does work, your method is better since it does not require physically removing power from the HDD/SSD.īut lately I issue the following before removing SATA power from a HDD I am issuing a secure erase on. it seems to vary a bit from computer to computer on whether what you said works or not. but I think putting a computer to sleep and waking it back up does work on a HP2000 laptop I got to get the HDD/SSD to a 'not locked' state, but I rarely use the HP2000 laptop for this stuff since it's more limited vs a proper desktop computer which is much easier to connect random HDD/SSD's to. If I recall correctly putting computer to sleep mode and waking it up does not work on the backup computer (ASUS A8N32-SLI Deluxe motherboard, basically high end 2005 tech) I have for getting a HDD to a unlocked ('not locked') state. Tip: suspending (hence removing power from the drive.) the machine works to unlock secure erase: echo -n mem | sudo tee /sys/power/state But 'secure erase' typically requires one remove the power to the drive during the process with the PC running to get it to a unlocked state before secure erase can proceed.
