This is a pre-release version for testing.
Notable changes in this release - ShredOS
- Add grub2 bootx64.efi modules for PXE booting: The EFI boot loader file bootx64.efi has been rebuilt with the extra grub2 modules, all_video, video_cirrus, video_bochs, net, efinet, tftp and gzio. This will hopefully fix the problem referenced here: #147.
- Fixes no logs written to USB when --autopoweroff added to grub.cfg by user
Fixes issue #145 If the user has specified --autopoweroff in grub.cfg, ShredOS shuts down the computer before it has written the nwipe logs and dmesg.txt data files to the USB flash drive. This is corrected in this release. ShredOS parses the nwipe_options and if it finds --autopoweroff it replaces with --nowait and then ShredOS's nwipe launcher script handles auto shut down of the computer once the logs and dmesg.txt have been written to USB. - Now auto creates /dev/loop0 & /dev/loop1 if user specifies those drives in grub.cfg
For development & testing purposes, ShredOS now supports automatic creation of two 1MByte virtual drives, /dev/loop0 and /dev/loop1. To have nwipe display these drives just add the following to the linux command line in /EFI/BOOT/grub.cfg and /boot/grub/grub.cfg. nwipe_options="/dev/loop0 /dev/loop1" These drive names should follow any existing nwipe_options you have. i.e drives must appear last in the nwipe_options string. Note, as these virtual drives will exist in RAM and are only 1MB in size they will wipe very fast. A single round will complete almost instantly and due to being so fast, the stats will not update as they require a few seconds to stabilise. So to see stats on a small loop device you may have to select 10s or 100s of rounds to achieve a total wipe time of more than 5 seconds. - dmesg.txt now written to USB flash drive: To aid in debugging ShredOS, the output of dmesg (the kernel log) is written to a file called dmesg.txt. When nwipe exits or is aborted (Control-C) dmesg.txt will now be written to the fat32 formatted USB flash drive along with the nwipe logs.
- hdparm was updated from v9.62 to v9.65: v9.65 is the latest version as of June 2023.
- Bumped minor version 23.2 to 23.3: (v2021.08.2_23.2_x86-64_0.34 to v2021.08.2_23.3_x86-64_0.34)
Notable changes in this release - Nwipe
No changes. There will be lots of nwipe changes in the v0.35 release. HPA/DCO detection, PDF reports, ATA secure erase.
Note
- The .img file for writing to a USB flash drive is both legacy (bios) and UEFI bootable.
As this is only a preview for testing booting on previously non bootable devices I'm not planning on creating .iso's or 32bit versions, unless somebody specifically has a system that for some reason they cannot boot using USB.
