My ForteRAID does not show up correctly in Windows while connected via eSATA (Models above 2TB).

A 3TB, 4TB, 6TB, 8TB ForteRAID drive may appear to be smaller than it's actual size when plugged in to an eSATA port on Windows Vista and Windows 7. The ForteRAID may appear as the expected size if the drive is previously formatted using a different eSATA controller, USB, or FireWire.

Microsoft has posted their own knowledgebase article about the problem.

This can happen if the controller driver underreports the total number of sectors on the disk. In this scenario some read or write attempts may fail and data loss is possible. Customers experiencing this problem should contact their SATA controller vendor for updated drivers.
