The multiple drive USB memory devices normally contain one or more
removable disk-type memory spaces, but can also contain virtual CD
drive-type memory spaces. The Wellwash Versa does not support
virtual CD drive-type memory spaces.

It is possible to check if there is a virtual CD drive present when
inserting a multiple drive USB memory device into the PC USB port.

1.

Select

My Computer

and note the new drives that appear in the list

when the multiple drive USB memory device is inserted.

2.

Check all the appearing items by using the right-click mouse menu
and selecting

Properties

.

3.

The item type "Removable Disk" is stated for the USB memory
device in the

General

sheet. It is compatible with the Wellwash

Versa if the File system is FAT16 or FAT32.

4.

If the item is a virtual CD drive, then the type will be "CD Drive".
This may cause the USB memory device to be incompatible with
the Wellwash Versa.

The problems covered below are considered faults that require repair or
corrective work (Table 13–14). If problems occur or reoccur, contact
authorized technical service immediately.

Table 13–14.
