Hello trid users,
some days ago i use software h2testw again to test some USB sticks for
faked capacity. This software writes and reads test data with file name
extension h2w. These data file are described by trid often as "Unknown!"
and some times as "Adobe PhotoShop Brush" ( see appended
output/trid-old.txt)
So i run tridscan to generate trid definition file h2w.trid.xml. The
original Windows software can be found for example at
https://www.heise.de/download/product/h2testw-50539 .
Luckily the Unix software package f3 (f3write f3read, etc.) also use this
file format. So i use the web site of that software as reference by line:
<RefURL>
http://oss.digirati.com.br/f3/</RefURL>
When the test data are written the data files can be read again to test
integrity of storage device again and again. If you are satisfied with
test scenario you can delete this files. So i mention this fact in remark
line. Because some times i test devices for other people and forget to
delete h2w files and then the other person probably do not know that this
files can be removed to gain more free space on inspected storage device.
With new trid definition all hundreds of inspected H2w examples are now
recognized ( see appended output/trid-new.txt). TrID definition and output
are stored in archive h2w_trid.zip. I hope that the XML file can be used
in future version of triddefs.
With best wishes
