The SSD will then block all normal access until it is re-locked with the correct password. Warning: If you set the user password, the SSD will entire the locked state after re-booting. The security feature will be enable thereafter. In the example, we have used the password, Eins. So that you can execute a secure erase, you must first define a user password. Transport: Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6Ģmin for SECURITY ERASE UNIT. In the first step, check if the SSD is in the not frozen state and support SSD Secure Erase (supported: enhanced hdparm -I /dev/sdb Important Note: Only execute a secure erase when running the SSD directly from a SATA port, since problems may arise otherwise. If you want to perform a secure erase, pay special attention to the correct device name, so that you will not erroneously delete the wrong drive. In the example, the SSD to be deleted has the device name /dev/sdb. We have taken the following steps from the ATA wiki at. This option expects one or more sector range pairs immediately after theįlag: an LBA starting address, a colon, and a sector count, with no intervening spaces.ĮXCEPTIONALLY DANGEROUS. This makes those sectors available for immediate use by theįirmware's garbage collection mechanism, to improve scheduling for wear-leveling of theįlash media. The drive firmware to discard unneeded data sectors, destroying any data that may haveīeen present within them. The hdparm tool for Linux provides an additional option, however the man page advises against using the option with hdparm version 9.27 (Ubuntu 10.10):įor Solid State Drives (SSDs).

Windows 7 automatically performs a trim when formatting, as do the Ext4 from mke2fs 1.41.10 and XFS from xfsprogs 3.1.0. įor other SSDs with integrated encryption, which do not sufficiently document the behavior of a secure erase, deleting the SSD blocks using trim would be recommended in addition to a secure erase, in order to get the ideal performance for re-use of the SSDs. For Sandisk SSDs the behavior is differnt, a Secure Erase does not erase all NAND.

The primary reason is that a secure erase should return performance to its initial state even with these SSDs.

When asked at the end of the Optimizing Solid-State Drive (SSD) Performance for Data Center Applications session at Intel Developer Forum 2011, Tahmid Rahman, Intel Senior Technical Marketing Engineer, informed us that the Intel 320 Series SSDs and Intel 710 Series SSDs with integrated encryption would also continue to delete the flash blocks despite this ability to delete only the key. Deleting the key would be sufficient to for a secure erase the data could then no longer be decrypted, but would still physically exist. Such SSDs automatically encrypt all data that has been written. The SSD will then be usable at its original ideal performance level, since all pages can be written directly (see Solid State Drive - Writing).įor the newer SSDs with integrated encryption, secure erase may be implemented differently. Most SSDs support secure erase, executing it for the physical deletion of all blocks on the SSD. According to the ATA specification, a secure erase should guarantee the secure erasure of all stored data on a storage medium.
