I found that Thinkpads have hdd password support, which in terms uses some bizarre password hashing and ends up with 90 bits of entropy, which is again used as ATA security password to SED, which in terms encrypts the HDD:s own build-in al… Continue reading Are there any motherboards / UEFI that support hardware encryption on SED?

Researchers have found serious weaknesses in self-encrypting solid-state drives (SSDs) that could allow attackers to compromise data stored on them without knowing the encryption password. Researchers Carlo Meijer and Bernard van Gastel from Radboud U… Continue reading Flaws in Self-Encrypting SSDs Compromise Data Encryption
I have been exploring data security lately and came across HDD data recovery. I now know that a format simply deletes the “pointers” to files and directories and that data is still there. The only way to completely wipe the drive is to eit… Continue reading How secure is Secure Erase option in BIOS?
I’d like to wipe a stack of drives (spinning and SSD) securely. I’m familiar with the ATA Secure Erase (SE) command via hdparm, but I’m not sure if I should use the Security Erase (SE+) command instead.
There is some evidence that these co… Continue reading What is the difference between ATA Secure Erase and Security Erase? How can I ensure they worked?
When I turn my notebook on, it asks me for the password to unlock the BIOS and than it asks me for the password to unlock the hard drive.
How different is this ‘password to unlock the hard drive’ from the so-called full-disk encryption i… Continue reading Unlock hard drive vs full-disk encryption
While looking at various hard drive encryption methods, I discovered that HP’s “DriveLock” is not quite the standard ATA security system. While I did get confirmation from HP that it does indeed use ATA security commands to lock and unlock… Continue reading What does HP DriveLock do to your password?
