File Name: tempo_x_esata_4+4_qsg.pdf Document Version: QS-TSATAII-X44-E-A-080508 File Size: 1.7 MB Installation instructions for installing the Sonnet Tempo-X eSATA 4+4 8-Port Serial ATA PCI-X Host Adapter into a supported Mac or Windows computer.
A very small number of Tempo-X SATA 4+4 users have reported a condition in which connected drives installed in an external case intermittently do not appear when their computer is booted.
To address this issue, update the Tempo-X SATA 4+4 card's firmware to version 1.0.1 or later by downloading and running the latest Tempo-X firmware updater.
This does not happen often, but sometimes the driver caches do not get purged and the new SATA driver does not get loaded correctly from ROM.
Try this:
1) Delete and empty trash for the following file and two directories:
/System/Library/Extensions.mkext (a file)
/System/Library/Caches/com.apple.kernelcaches (a directory)
/System/Library/Caches/com.apple.romextensions (a directory)
