Scenario Erasure of read and write disk caches on unmount: vfat
Before features/support/hooks.rb:269 0.002
Steps
Given I have started Tails from DVD without network and logged in 8.365
And I prepare Tails for memory erasure tests 0.402
When I plug and mount a 128 MiB USB drive with a vfat filesystem 9.276
Then I find very few patterns in the guest's memory 4.626 
Pattern coverage: 0.000% (0 MiB out of 894 MiB reference memory)
# write cache
When I fill the USB drive with a known pattern 2.648
Then patterns cover at least 86% of the test FS size in the guest's memory 4.018
85.538% 
85.538% of the test FS size (127.599609375 MiB) has the pattern, but more than 86.000% was expected.
<false> is not true. (Test::Unit::AssertionFailedError)
