From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If I issue an hdparm secure erase against a drive that does not have it? (lemmy.one)

I am zeroing out some old drive - some may not have secure erase. If I issue the command:

hpparm --security-erase-enhanced

Against a drive that does not have this feature, will it error? Man does not tell me.

With the command hdparm -I /dev/sdX you can check if ATA Secure Erase is supported by the respective hard disk. If the output shows among others things supported: enhanced erase this is the case. Instead of sdX you must of course specify the respective hard disk.

Edit: You should run this command anyway to make sure that the hard disk in question is not frozen (https://archive.kernel.org/oldwiki/ata.wiki.kernel.org/index.php/ATA_Secure_Erase.html#Step_1a_-_Ensure_the_drive_is_not_frozen:).

Ok My drive does not have the feature - and took the hdparm --security-erase-enhanced without any error. I guess I will use dd then.
