Hallo Aaron,<br>
<br>
Finally i did setup the external SATA port to install directly onto<br>
the SSD which i used via a SATA - USB adapter taken from an<br>
external harddisk.<br>
Now it's running without any problems since then and is still running.<br>
The SSD meanwhile went into the case.<br>
<br>
For the external SATA port i had to find a modified BIOS for the HP<br>
microserver. There are some fans who have the knowledge to modify<br>
the BIOS and activate the port ...<br>
<br>
Thank's for your useful hints.<br>
<br>
Tschuess,<br>
