Disk: Update Size value in example

[fullenw1]

This Pull Request (PR) fixes the following issues

A value with a size unit (like MB or GB) does not work.
It generates the following error message:

Compilation errors occurred while processing configuration 'DscConfigurationName'. Please review the errors reported in error stream and modify your configuration code appropriately.

• CategoryInfo : InvalidOperation: (DscConfiguration:String) [], InvalidOperationException
• FullyQualifiedErrorId : FailToProcessConfiguration

Entering only a number works fine.

Hi @fullenw1 - that is really strange. Using 10GB etc should work and passes the example compilation tests. See: https://ci.appveyor.com/project/PowerShell/StorageDsc/branch/dev?fullLog=true#L565

How are you compiling the examples?

Hi @PlagueHO

How are you compiling the examples?

As I got the error message, I spotted by dichotomy the size parameter.
My intended value was different but I gave a try to 10GB like in the example (just copied/pasted the value) and got the same error.
When I used 10737418240 (the size in bytes), the error message disappeared.

By the way I got the exact same behavior on another resource:
dsccommunity/ComputerManagementDsc#278

I tried this as well yesterday and you're right - it is failing. Not sure how the Example tests are passing though. That is something I should look into. Anyway, let's proceed with this change.

Can you add an entry into the CHANGELOG.MD for this change?

Done!
Please have a look. First time I do this on a DSC module...

Closing because superseded by #218
