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. I would love to learn about other people's experience with the application.According to the ATA specification, a secure erase should guarantee the secure erasure of all stored data on a storage medium. I still make some additions/changes occasionally, but there's no exact roadmap. Didn't have to deal with forensics experts yet though. I have been using the application for some time for personal needs on all supported platforms. The initial active development phase is done. The application hasn't even been tested on RAID storages, beware.For example, using a block size of 1 MB the size of the storage can be up to 4096 TB. The maximum number of blocks per storage device is 2 32, or 4,294,967,296.Later, a support for Secure Erase ATA commands may be added to make the process more reliable. The best approach currently is to use multiple wiping rounds with random data. For SSD, it's impossible to reliable wipe all the data because of the various optimizations performed by modern SSD controllers, namely wear leveling and compression.Tracks & skips bad blocks and other localized errors automatically (Experimental).Allows to override OS recommended block size for possibly faster operations.

Uses fast cryptographic random generator.Validates the data (reads back) to make sure all write commands were successful.Supports Windows (but not WSL), macOS and Linux.Or non-cross-platform, which was a requirement for me. There are other similar applications around (including multiple built-in Linux tools). In other words, on overwriting existing data with multiple layers of randomly generated data or some The usual methods for wiping (or sanitization) a drive, including those (allegedly) used by government agencies are based Should work with any HDD, SSD (read limitations) and flash drives. A secure, free, cross-platform and open-source drive wiping utility.
