Q: Problems when I want to refresh my Mavericks system by using an USB-stick with the complete installer.
I want to "refresh" my Mavericks system by a clean install and I have still an USB-stick with the complete installer.
With this USB-stick I successfully installed Mavericks already before. Now I want to repeat the installation by booting from USB-stick. But when the installation starts quite early an alert appears, says something like "… the verification failed–something is changed on the volume …" and the installation cant continued.
I archived the original "OS X Mavericks installieren.app" from app-store and I properly prepared another USB-stick again using the terminal-app referencing the original installer, but I still get this alert when I try to install with this new USB-stick.
It is necessary for me to work with Mavericks because it is the last system version on which I can run Adobe Creative Suite CS6 properly. With later OS X versions I get problems on my Mac Pro (late 2008).
I wonder what could happened with the data on my first USB-stick, because I already installed Mavericks successfully with it under same conditions and after it never touched the stick again until now. What can I do? What is the reason for this? Is there any site where I can get support or a hint to solve the problem or if necessary can I download a "fresh" installer again?
thanks and regards from Berlin
Mac Pro (Early 2008), OS X Mavericks (10.9)

Thank you Eric. I already tried the Diskmaker X additional if this works better than the terminal methode, it is quite more comfortable with this program especially for users who are not so familiar with command-lines. But in my case the problem stays the same. And I tried to repair with the disk utility tool, this has not found any problem, the USB-stick seems to be ok. Anyway I run the repairing process and tried again to install Mavericks—but still same alert appears and stops the installing process.
I cannot understand why Apple do not keep downloads for older versions of OS X reachable, not all users have Macs which are able running the recent system. Does any know a solution for this problem?
Thank you.
PS: Meanwhile I tried out the USB-stick with Mavericks-installer of a friend of mine which he independently made that time for his Mac and it is the same problem—interesting.
