JBOD issue

[Harry Cover]

SL 10.6.8
JBOD (USB 2.0)

When I launch SD, cloning an external HD to a JBOD, I have noticed the following issue:

- The copy starts.
- The RAID is ejected.
- I have the usual Finder alert message telling me that this ejection was not safely done.
- The copy is interrupted.

I have tested the same copy with Carbon Copy Cloner: same problem.
So, SD is not the culprit.
The bad ejection of the RAID blocks the cloning.

Any suggestion ?
Thx in advance

This is a communication problem with the drive. It could be the cable, case, port or drives...but it's a hardware issue.

You are right Dave... as always. ;)

It is an USB problem.
SD does its magic when all the HD are directly plugged into the mac... but... problemo: 3 USB HD + 1 USB hub.
Where am I going to plug my keyboard ???
Working without it does not seem to be so easy. ;)
Could I plug it to itself ? :rolleyes:

USB drives don't like hubs... :)
