There are many fraudulent USB sticks in circulation that report to have a high capacity (ex: 8GB) but are really only capable of storing a much smaller amount (ex: 1GB). Attempts to write on these devices will often result in unrelated files being overwritten. Any use of a fraudulent flash memory device can easily lead to database corruption, therefore. Internet searches such as "fake capacity usb" will turn up lots of disturbing information about this problem.

`errinj_wrong_capacity` reports a wrong storage capacity. There are many
fraudulent USB sticks in circulation that report to have a high capacity (ex:
8GB) but are really only capable of storing a much smaller amount (ex: 1GB).
Attempts to write on these devices will often result in unrelated files being
overwritten. Any use of a fraudulent flash memory device can easily lead to
database corruption, therefore.

With error injection `errinj_wrong_capacity` filesystem reports a wrong
storage capacity. Problem simulated with `errinj_wrong_capacity` may
happen in real. For instance see a case described in SQLite
documentation: "There are many fraudulent USB sticks in circulation that
report to have a high capacity (ex: 8GB) but are really only capable of
storing a much smaller amount (ex: 1GB). Attempts to write on these
devices will often result in unrelated files being overwritten. Any use
of a fraudulent flash memory device can easily lead to database
corruption, therefore."
