Question: I’m trying hdparm in Kali Live to add a ATA password to my Micron M600 Self-encrypted SSD, I use: hdparm –security-set-pass PASSWORD sda
But I get:
sda: ?Issuing SECURITY_SET_PASS command, password=”PASSWORD”,user=user, mode=high SG_IO: bad/missing sense data, sb[]: ?70 00 05 0000 00 00 0a 04 51 60 00 21 04 00 00 00 00 00 00 00 00 00 00 00 00 0000 00 00 00 00
So why does this happen?
When I type hdparm -I sda, it shows my drive is “security frozen”, I remember that means I cannot change any security settings including add ATA password, is that the problem?
My BIOS doesn’t support ATA password, and I’ve never set it before.
EDIT: The Security part of hdparm -I:
Security: ?Master password revision code = 65534 ?supported ?not ?enabled ?not ?locked ?frozen ?not ?expired: security count ?supported: enhanced erase ?2min for SECURITY ERASE UNIT. ?2min for ENHANCED SECURITY ERASE UNIT.
The format on this website is always messed up, but I try my best to keep the contant readable.
Answer: Partial answer, because it’s too long for a comment:
The sense data given reads:
70 ?response code=Current information (about the error etc.)0005 ?sense code=Illegal Request00 00 00 00 (not valid)0a ?additional 10 bytes04 51 60 00 ?(command specific)21 04 additional sense code=Unaligned Write Command00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
So the error is “Illegal Request, Unaligned Write Command”. That doesn’t make particular sense if hdparm is using an ATA writethrough SCSI command.
I have no idea why this happens. If it’s the reaction to the “security frozen” state, it’s a really strange reaction. Possibly something in the SCSI-to-SSD translation layers doesn’t like the ATA write through command?
Do you know for sure the Micron M600 SSD supports ATA passwords?
Edit: The manual you linked says:
?
Micron’s SEDs support either the TCG Opal 2.0 specification or the ATA SECURITY FEATURE SET. The ATA security modes are generally initiated by system BIOS or by some ?universal extensible firmware interface (UEFI)-based systems in legacy mode. By specification from the associated industry standards organizations, TCG Opal and ATA security are mutually exclusive. In other words, if one is enabled, the other is disabled.
So if your BIOS doesn’t enable it, it won’t work. “Frozen” just means you can’t change the state.
Please edit your question with the full output in the Security section of hdparm -I.
Edit
The hdparm -I output clearly says “not enabled”, but “frozen”. So your BIOS didn’t enable it, but froze, so you can’t change the state.
That means your SSD is in TCG Opal mode, and I’ve no idea how to access that under Linux.
Power cycling it while plugged is worth a try.
If you can find another computer with a BIOS that let’s you set the password, or that doesn’t freeze it, you can try it that way, too.
