  • OK, to be clear, you can boot to raspbian or your distro of choice and use hdparm if you have a proper SATA controller and connection. This does not work on NVME drives.

    #shred

    If you have a spinning disk and either are forced to use a USB to SATA adapter or if the drive itself does not support secure erase, then you can use the shred command.

    shred -fv /dev/sdb

    will write random data to the sata device sdb. f is for force and v is for verbose. You can add z to add an extra zero pass and z to change the number of passes. That means that

    shred -z -n 5 /dev/sdb

    should do 5 passes and then zero on drive sdb

    It will ALSO work for older parallel drives that identify as hd or that still appear as sd with a USB adapter. You had better check your devices with a lsblk before you run it. It will probably overwrite the OS of a running system.

    Last word on shred is that it is ungodly slow. One pass of 1 tb takes 1.5 to 3 hours.

    #hdparm

    For SATA drives that support it, you can use hdparm. A deep explanation of what I’m doing is available here: https://grok.lsu.edu/article.aspx?articleid=16716. I could write out how to do it, but it goes into greater detail.

    For forcing the system to sleep, you may need to

    echo disk | sudo tee /sys/power/state

    Also, be sure to set a password when prompted. If you omit the password, you may brick the drive. I have rarely been able to unbrick a drive.

    This process may take several hours. The output of hdparm -I (that is an uppercase i) should tell you how long.

    #NVME

    Check processes here: https://wiki.archlinux.org/title/Solid_state_drive/Memory_cell_clearing#NVMe_drive

    I have followed them once upon a time, but i haven’t done it in years and cannot offer solid advice.










  • since 11 was forced on us at work.

    Windows 10 is coming to end of life and your org is basically being forced to upgrade themselves. Many people are sad to see it go.

    Personally, I left Windows 11 for Linux Mint because I bought 11 Pro OEM and was downgraded to home with 11.

    Professionally, I am doing my best to acknowledge people’s loss in the workplace as I migrate them to 11.









  • The legality of abandonware is disputed. Traditionally, even if the IP is unavailable, it doesn’t make it legal to distribute. Copyright law is also defined jurisdictionaly. I’m not defending copyright, but it is important to understand risks when accessing this.

    Now, in the States, I didn’t believe receiving or even playing this game system would be illegal, but people have been jailed for making and distributing such devices. Our corporate overlords also have no qualms about squelching content based on perceived copyright violations.

    This influencer is in Italy, and the laws seem to be heavily against owning such system.
