Sonnet Tempo-X eSATA card PCI-X

I had the same problem as everyone since I upgrade my OS from TIGER to LEOPARD with my RAID and the Sonnet Tempo-X eSATA PCI card. I have instaled the new firmwire 2.1.2 and everything seems OK. My RAID works properly since now two hours.

Any answers yet on this topic? Our raid is still playing back video at half the rate it did pre 10.5

OK

I can't claim the credit; the solution came from Neal at Sonnet, it worked for me:

Intel machines don't use firmware on cards. That's why there is a separate Mac Pro driver. You can't update the firmware on the card because you don't need to. Even if you moved the card to a G5 or similar and updated the firmware to 2.12, the Mac Pro would still ignore said firmware.

So you have the correct version of the Mac Pro driver. 2.12 ( http://www.sonnettech.com/support/downloads/computercards.html). You might try this trick and see if it helps:

Delete and empty trash for the three (3) following files and directories:

/System/Library/Extensions.mkext (a file)
/System/Library/Caches/com.apple.kernelcaches (a directory)
/System/Library/Caches/com.apple.romextensions (a directory)

The last directory might not exist so don't worry about it if it isn't there. Restart after you do this so OS X will rebuild some of the files.

I had a weird log in screen first time round which hid my password, but got in as guest and then logged out to find that all was fine: disk utility doesn't hang and all is well
