Thunderbolt Pegasus R4 Experience?

Has anyone else got any first hand experience of the Promise Pegasus R4 (or R6) with their iMac? I bought mine this week and managed to load it up with around 1.4Tb (it holds around 3Tb) no problem. Now, today I can't get the drive to stay connected before it ejects for more than 5 minutes. It's driving me mad and I'm very concerned as I moved all my family video onto it from another drive and it won't stay connected long enough to get it back onto another drive again.

iMac, Mac OS X (10.6.8), 2011 i7 3.4, 256Gb SSD and 16Gb RAM

How is your Pegasus configured as to Raid level?

I have heard that the use of a Raid 0 array as startup disk would not be advisable nor convenient.

My Pegasus is configured as a RAID 10.

You're lucky you haven't encountered the problems with the older firmware. My advice is to call someone at Promise technical support 408-228-1500.

Tried the suggestion in your post and it seems to work (fingers crossed).

This solution fixed my problem and with a previous Imac had the same problem a couple of years ago and this was the solution that fixed it as well .

Thanks
