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.
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.
