| 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. |

| 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. |
