| How do I set up a RAID 0 striped array under Windows XP Professional or Vista? | Mar-23-10 |
| To create a striped array you must first have at least two drives with a portion of 'unpartitioned space' free. The largest stripe you can create will be twice the size of the smallest unused space on either of the disks. If you have two disks, one with 500GB of unpartitioned space and one with 750GB, the largest striped array you could create would be 2 x 500GB = 1000GB, as the area of space used by the stripe on each disk must be the same.
The first step is to convert both disks from basic to dynamic disks within Windows. A dynamic disk is a disk that contains an additional database of other dynamic disks on the system. Dynamic disks can only be read by Windows XP Professional, Windows Vista, and the various Windows Server operating systems, and are required to create software RAID arrays within Windows.
To convert a disk from basic to dynamic, follow these steps:
1) Right click the grey box on the left that contains the disk names (disk 1, disk 2, etc.) and select 'convert to dynamic disk'.
2) From the next window you can check both blank drives and click 'ok' to convert them.
3) Once both disks are listed as dynamic, right click the 'unpartitioned space' of either drive and select 'new volume.'
4) In the 'select volume type' window, select 'striped.' Add all disks you wish to use, then decide on the amount of space on both disks you wish to use for the striped volume you are about to create. If you wish, you use only part of each disk for the stripe, leaving the rest free for other uses.
5) Choose a drive letter or folder to use, and the method of formatting, and you are done. The striped array will format and be ready for use. |

| Unable to format hard drives after moving a Fusion storage system from a Mac to Windows computer. | Mar-23-10 |
| If you move your Fusion storage system from a Mac to a Windows computer system and try to format the disk using the Computer Management Console in Windows, the disk will show up as a GPT Protective Partition with no way to format it.
To properly format the disk, follow these steps:
1) Open a Command window (Start > Run > cmd), then start.
2) List your disks with list disk, then select the appropriate one with select disk X (with X the number of your disk as seen in the listing).
3) Issue a clean all command to erase all information on the disk. At this point you may be able to use the disk again from the management console;if not, continue with a create partition primary. |

| My storage shows 10% more capacity under OS X 10.6 than under OS X 10.5. Why? | Mar-24-10 |
| With Snow Leopard (10.6), Apple adopted the standard usage of terabyte (TB) which equals 1,000,000,000,000 bytes = 10-to-the-12th bytes. Hard drive manufacturers have always specified drive capacity with standard usage which will now match what Mac OS X reports.
WIth Leopard (10.5) and previous versions of Mac OS X, Apple used the binary interpretation of terabyte, (technically a tebibyte) = 1,099,511,627,776 bytes = 2-to-the-40th bytes. Windows also uses binary interpretation.
Under Snow Leopard, drive capacity will be shown per drive specifications. For example, under OS X 10.6, a 1TB drive will appear as a 1000 GB capacity drive (but under OS X 10.5 as a 909 GB capacity drive). For additional information see support.apple.com/kb/TS2419.
What does this mean in real terms? Do I get an immediate increase in storage space?
Formatting or actual capacity does not change at all, only the reported capacity because of the change from base-2 to base-10.
Should I reformat the drives before attempting to plug in a previously 10.5 formatted unit into a 10.6 machine or vice versa?
Reformatting is not necessary at all.
What happens if I plug a 10.6 formatted unit into a 10.5 machine or vice versa?
The volume is seen normally. It is completely compatible and can be transparently moved back and forth. |

| Only the first drive of my Fusion D400Q, D500P, R400P, or R400Q is recognized when I connect via SATA. Why? | Mar-24-10 |
| You are using a SATA port that is not port-multiplier aware. For example, the internal SATA ports in a Mac Pro that may be brought to the PCIe rear panel via an eSATA extender cable are not port-multiplier aware. All of Sonnet's Tempo SATA cards with external ports are port-multiplier aware. |
