1. Fix a bug in the static and random pass code
where I unnecessarily moved the decrement of z (the
count of bytes remaining) to after the periodic sync
which meant every time it sync'ed z wasn't decremented due
to r being used as a general results variable for the
fdatasync function.
I prefer to just have a variable be responsible for just
one thing hence my assumption r wasn't used for two different
things.
Changed the position of the decrement of z, pass_done and
round_done to their original position prior to the periodic
sync.
1. Added the red cross icon located on the top right of
the certificate. This is displayed when the wipe is aborted
or failed to complete due to disc I/O errors etc. The
green tick icon is displayed on a successful wipe.
2. When the user manually aborts the wipe, the bytes so
far erased incorrectly displayed as zero. This change updates the
c->bytes_erased variable in the static pass and random
pass functions to correct this.
1. Added rounds requested & completed. Coloured
green if equal and red if not.
2. Fixed endtime sometimes not being recorded when
a wipe is aborted. This affected the creation of the
PDF filename. Now ok.
3. Added throughput using the appropriate nomenclature
such as KB/sec MB/sec, GB/sec etc
1. Added bytes erased including percentage, green
if equal to disc size and red if the drive hasn't been
fully erased at least once.
2. Added explanation of bytes erased to certificate.
3. Added throughput
1. Change model/serial no in header to bold and move left
2. Create a filename for the report that identifies the
wipe uniquely ie:
nwipe_report_YY-MM-DD_HH-MM-SS_Model_XXXX_Serial_XXXX.pdf
3. Move size data 2 characters right to allow for up to two
space prefix on size string. So data doesn't get written over
the end of the 'Size:' label.
1. Fix @param in pdfgen.h, committed and accepted upstream
2. Added size of disk in bytes
3. When NVME drive show message "Not applicable" for HPA, DCO
4. Highlight status ERASED, FAILED etc with coloured ellipse
5. Added function help for nwipe_log (shows in hints in IDE)
1. Rearranged the layout so the Tech/ID signature
is at the bottom of the report.
2. Added start date/time
3. Added end date/time
4. Changed data from helvetica to helvetica-bold
5. Created a definition for PDF_DARK_GREEN text in
create_pdf.h and moved the previously created PDF_GRAY
to create_pdf.h, to keep pdfgen.h vanilla.
6. Added the erasure status, ERASED, FAILED, ABORTED.
ERASED in green and FAILED, ABORTED in red.
Further code to follow ..
1. Display unknown in serial number field for loopback device
2. Added device type, USB, SATA, VIRT etc
3. Added duration of wipe in hh:mm:ss
4. Added pseudo random number generator type, twister, isaac etc
5. Added final blanking pass type, none, zeros, ones
6. Added number of rounds
1. Changed most titles in certificate to gray with
the data in black.
Started adding real data to template including:
Model, serial no., method, verify, size.
more code to follow...
1. Embed the images contained in the PDF into nwipes code
rather than use external image files.
2. Changed the font from Times New Roman to Helvetica
to give it a cleaner look.
I was searching for a DBAN alternative that runs in a normal Linux distro so I can hot-swap drives and not hale to reboot the system. When I found nwipe, I went to install it in a grml live system. Turns out, nwipe ships with grml by default as you can see in [grml's dpkg.list](https://packages.grml.org/files/grml64-small_2021.07/dpkg.list).
It's not exactly the most up-to-date version (0.30-1+b2 for amd64) because grml is close to Debian stable. It even comes with the the small live system image.
Although reported in issues some time ago, make it clear nwipe doesn't support HDA and you will need to run hdparm in order to detect and if necessary correct the disks reported size prior to running nwipe.
