You need to be root to run this program.
0.a sudo -s
If the libata.allow_tpm flag was not set at boot time you need to change it,
optional steps 0.b & 0.c will do this:
0.b chmod 0744 /sys/module/libata/parameters/allow_tpm
0.b echo "1" > /sys/module/libata/parameters/allow_tpm
1. sedutil-cli --scan <- SCAN to find Opal Drive (you should see Yes next the the drive
your working with.
2. sedutil-cli --query /dev/sd? <--this will show the Opal status look at the locking
feature and see if it is Locked = Y
or LockingEnabled = Y that's a good
sign that this should work
3.sedutil-cli --yesIreallywanttoERASEALLmydatausingthePSID <PSIDALLCAPSNODASHES> /dev/sd?
4. You should see INFO: revertTper completed successfully.
If you get a message that says NOT_AUTHORIZED you entered the PSID wrong.
If it doesn't work please execute the command in step 3 with a -vvvvv (5 v's) as the first option
redirecting the output to a file and send it back to me.
example:
sedutil-cli -vvvvv --yesIreallywanttoERASEALLmydatausingthePSID <PSIDALLCAPSNODASHES> /dev/sd? > revertlog.txt
Hope this helps.
