Lacie's eSATA Hub |
A client of mine is having an odd problem. He's using a 4TB G-RAID as an edit drive and we're connecting it to his iMac via eSATA using Lacie's eSATA Hub. The hub converts the eSATA to Thunderbolt. We have a faster 4-drive eSATA RAID (from OWC) connected to the other eSATA port on this hub. The OWC eSATA enclosure has had zero issues, but we're having problems with the G-RAID.
If the computer and drives are off, and then we power on the drive, then the computer, the G-RAID mounts on the desktop each time without issue. But, if the computer is already on and we try to connect a SATA cable and turn the drive on, the G-RAID will not mount. So something, either in the G-RAID's controller board or something inside of the Lacie hub is preventing hot swapping. (PS - hot swapping is having the computer turned on, plugging in a drive and powering it on. It should mount to the desktop.)
I began to do some digging to see if I could find any similar issues on the net. I did run across a few folks reporting issues with SATA connectivity using 4th generation G-RAIDS. It just so happens my client's problematic drive is a 4th Generation G-RAID. In a few of the cases the remedy was to update the drives for the SATA card. Unfortunately in our case, the Lacie is a driverless piece of hardware, so no update is available.
My client has one other 4th Gen G-RAID and it has the same problem. We also tested with older G-Drives, also from G-Tech, and they hot-swap just fine. We also have an
OWC Mercury Elite Pro and it has no problems hot swapping. So it seems to be limited to 4th Gen G-RAIDs.
Thankfully we can at least get the G-RAID to work when we start everything up from power off. However, there are times when hot swapping will come in handy, so I'm hoping a remedy is found soon.
