| Connecting a Fusion D400Q or Fusion R400Q to computer system with USB or FireWire requires a hard drive in drive bay 1. | May-06-09 |
| The Fusion D400Q and R400Q must have a hard drive in drive bay 1 when connected via USB, FireWire, or FireWire 800. This requirement is due to the Oxford bridge chip that controls USB and FireWire connectons. Drive bay 1 is the top bay in the Fusion D400Q and the left bay in the Fusion R400Q. As long as there is a drive in drive bay 1, bays 2-4 are unconstrained.
Note: This requirement does not apply to a direct SATA connection, which has no drive bay population requirements. |

| 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. |

| 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 |

| The performance of my drive array is significantly less than I expect. | Jun-14-11 |
| Another manufacturer's previously-installed SATA driver may be accessing a Sonnet SATA card in error causing a drive access slowdown. For example, we have seen Fusion D400QR5 performance drop from 200MB/s to under 50MB/s in such circumstances. The solution is to remove the other manufacturer's SATA driver. |
