No disk error

[geojay]

I've just started using XAMPP and have added an existing website to its configuration by including the following lines in httpd.conf :

Code: Select all

Alias /dev "Z:\dev\site\www"
<Directory "Z:\dev\site\www">
   Options Indexes MultiViews FollowSymLinks
   AllowOverride All
   Order allow,deny
   Allow from all
</Directory>

Z:\ is a USB flash drive and XAMPP is at Z:\xampp

Every time I access any URL on this site I get the following Windows error message seven times:

WIndows - No Disk
Exception Processing Message c0000013 Parameters 75b6bf7c 75b6bf7c 75b6bf7c

Can anyone suggest what the problem is and what I can do to fix it?

Thanks
