Workaround: Parallels Desktop is not seeing my DVD Drive in Mountain Lion

by

Today I wanted to install Windows 7 using Parallels Desktop 7 on my Mac, but sadly I always got an error message every time I tried. It was saying it could not connect to my DVD drive – which clearly my Mac could.

Doing some research it turns out that several people had this problem, however I didn’t understand the instructions given by Parallels very well. Getting frustrated I decided to write my own, and give you some pointers where else to look for help.

For this scenario I’m using a DVD copy of Windows 7 Home Premium and the latest version of Parallels Desktop 7.0.15107. Parallels Desktop 8 is already out but I’ve decided not to upgrade at this point.

How to bring back Scheduled Backups in Plesk 11

by

For those of you who hadn’t noticed, automatic scheduled backups are no longer working in Plesk 11 with some distributions. It’s not just you, and it’s not just your configuration. It’s a known issue according to this forum thread.

Lucky for us there’s a simple script which can bring this ever so important functionality back. Why Parallels is not addressing this with a Micro Update is beyond me (we’re already at 11.0.9 MU15 and it’s September 2012 at the time of writing).

In this article I’ll show you how to install the script step by step. I assume you’re logged onto your system as root and know your way around the command line.
