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 Air Force.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.
