We have a virtual server (Windows Small Business Server 2011 Standard) running on a VMware virtual Host ESXi 5.5. There are 5 external Hard disks that are used to backup the customer data. these are Toshiba STOR.E BASICS - 2.5" - 1TB, (Part number hdtb110ek3ba). 4 of the 5 drive work okay when attaching to the Virtual host, one of them is not connecting. however, when I plug each of the drives in a PC, they are all detected and work okay. They are formatted the same and the only difference s the label of each drive (Mon-Fri).
When we connect the suspect drive into the Virtual Host, we don't have an option "USB Device" when we add hardware in the edit settings of the Virtual Machine. However for the other USB drives, or other Toshiba drives, we do get the option to add "USB Device".
Thank you in advance for any assistance
