It is tempting therefore to agree to complete encryption. However, as my laptop is my calculations' workbench, as well as office tasks, I am concerned that unexpected runtime errors may occur from encryption and there may be difficulties of transferability of data files to colleagues and students, and to eg

Hello,
Whole disk encryption is wise in case the machine is stolen.
On Linux and Macs (I don't know other platforms) this is transparent
and I don't see how it could trigger some runtime errors (once the
computer is booted: the files are seen unencrypted by the operating system).
The only concern may be that for some really I/O demanding applications
(like video editing), this may slow down the video processing task.
However, with decent hardware and file system, this may be just an old
concern which crystallographers really don't need to care about.
Another minor drawback is that you will possibly need a password to boot
your machine (on Linux at least).
Regards,

> Does anyone have experience of encryption? Are my anxieties misplaced? If not, will I need to plan to separate office files, which could then all be encrypted, from crystallographic data files/calculations, which could be left unencrypted. If separate treatment is the best plan does one need two computers once more, rather than the one laptop? A different solution would be to try to insist on an institutional repository keeping such files.
