Both, the VeraCrypt command line (--fs-options=big_writes) and the Vera- |
16 |
Crypt GUI (under "Settings --> Preferences") allow setting this mount |
17 |
option. But |
18 |
|
19 |
$ mount | grep veracrypt |
20 |
|
21 |
never shows it, initially causing me to erroneously believe it wasn't |
22 |
set and to try finding on the web another way of setting it. By pure |
23 |
chance I finally found out that |
24 |
|
25 |
$ ps -ef | grep veracrypt |
26 |
|
27 |
lists a "/usr/sbin/mount.ntfs" task which shows the options really in |
28 |
effect. However, I haven't yet had the time to test the effect of this |
29 |
option when writing plenty of really big files. I will report on that |
30 |
later. |

Sincerely, |
