| 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. |

| I upgraded the hard drives in my D500P to larger drives and only one drive is showing up. | Nov-29-15 |
| The D500P had enough power for the drives shipping at the time it was sold. Newer, bigger drives take more power to start up and may not all show up at startup.
You may solve the problem by switching to a Sonnet E4P SATA II controller. The Sonnet driver for the E4P implemented staggered startup, which supports any size drive in the D500P. Because the D500P also has a SATA II interface, there is no loss in performance using the E4P SATA II card. The newer Sonnet SATA III controller cards use drivers included in OS X and Windows that do not implement staggered startup.
As a temporary measure, you can power up the D500P and plug in the drives in succession, effecting a staggered startup.
You may also install a larger power supply. Contact Sonnet support for more information. |

| Can I use Seagate Iron Wolf drives; or Hitchai and WD drives 8TB and larger? | May-31-18 |
| Some newer drives use a hole pattern different from the traditional drive hole pattern for the bottom mounting points. The location of the bottom holes close to the connector did not change; however, the bottom holes near the middle have been removed and replaced with bottom holes close to the front of the drive.
The drives with the new bottom hole pattern include:
Seagate Iron Wolf drives (also missing the middle hole from the side mount hole troika)
Hitachi drives 8TB and larger
WD drives 8TB and larger
Incompatible mount holes
Echo 15+ Dock (side mount, but needs middle hole, so incompatible with only Seagate Iron Wolf)
Fusion F3 (bottom mount)
Fusion D400Q/R400P/D500P (bottom mount)
Fusion D800/R800 (bottom mount)
Compatible mount holes
Fusion R400S RAID (side mount)
Fusion R400 RAID USB 3 (side mount)
Fusion DX800/RX1600 (side mount) If using Iron Wolf line, must use Iron Wolf Pro with rotational vibration sensors
