File Name: qio_pc_ug.pdf Document Version: QIO-PC-E-B-110514 File Size: 1.3 MB Description: Windows user's guide for the Sonnet Qio Professional Universal Media Reader/Writer Plus Four eSATA Ports. This manual applies to QIO-E34 (Qio with the PCIe Bus Extender ExpressCard/34 adapter) and QIO-PCIE (Qio with the Bus Extender PCIe adapter card).
There is a very limited resource in PCI I/O space in PCs. There is not enough I/O space for the Compact Flash drivers to start. Often this can be fixed by moving the Qio PCIe expander to a different slot.
This is a Microsoft Windows driver bug with some 64GB CF cards. Sonnet is working with Microsoft to resolve this issue. (64GB and 128GB CF cards work fine with Qio and Qio-CF in OS X.)
A partial list of cards Sonnet has tested:
Patriot Pro CF 266x 64GB/128GB card is recognized under Windows
Lexar Pro 1000x UDMA 7 64GB/128GB card reports itself as 32GB
SanDisk Extreme Pro UDMA 6 64GB/128GB card reports itself as 32GB
