Seagate ST31500341AS 1.5TB
Any idea when this will be supported :-) Cliff
I posted above about my problem with trying to move from 2 x 750GB to 3 x 1.5TB. Just to provide an update: it didn't work. The data was all there, but it kept wanting to find a 4th disk.
After a lot of fruitless experimentation, I reset the thing and it now has the 3 1.5TB drives running fine. (Yes, I have just ordered a 4th.)
One thing I wanted to mention was the post that Balders made regarding my breaking the array. I'm sure that's what happened. However, he says that I should have replaced the 750GB drives one at a time.
Yet, that's essentially what I did. In the Netgear documentation it states "The newly added disk(s) must be at least the same size as the smallest existing disk. Note that you can add one or more disks at a time." I added the two 1.5TB drives and let the machine initialize them both overnight. In the morning. I removed one of the 750GB drives, put in the third 1.5TB drive, and left for work.
When I came home it was happily telling me that it had 3 1.5TB drives and 1 750GB drive, allocating roughly 695GB to each of the four.
The problem came when I removed the last of the 750s and rebooted. It never allocated reallocated the space. Again according to Netgear's FAQ "When you replace each of the smaller disks to the larger disk capacity, X-RAID will expand itself to utilizing all the space from this larger disk."
My expectation (incorrect expectation, I should add) was that it would expand the 3 1.5TB drives to ~2.7TB under X-RAID.
Balders correctly stated that you "cannot move from 4 drives to 3." When I reread the FAQ item it states "replace each of the smaller disks..." That was the problem: I wasn't replacing the last small drive, I was just removing it.
Doh!
Perhaps this will prevent someone else (with my limited knowledge) from falling into the same trap.
Thank you for your help.
