November 5, 200817 yr ilovejedd, I am on a 100mbps network (actually using a modem/router from my ISP provider) and I was copying files ranging from a few Kb to 2 Gb in size. Any suggestions? Then those transfer speeds are fine. I guess I forgot to mention that I was on a gigabit network. Maximum throughput you can get on fast ethernet is 12.5MB/s. If you add overhead and take into account that samba isn't really the most efficient protocol there is, 8.5MB/s is normal.
November 5, 200817 yr Just curious, which drive did you return? Did you run a SMART test on the drive with serial ending in W1H? Forgot to respond earlier, but Brian did. Couple of other comments to add: As you indicated, Tray 2 and Mobo connector #1 do look suspicious. The parity drive (serial ending in 0GT) and Mobo connectors #0, #2, and #5, and Trays 1, 3, and 6 all looked fine, at least from the preliminary testing you did. The parity sync was not a good test for isolating which drive was producing the clicks, because it works both drives. A better test would have been one that only read from or wrote to a single drive. One quick way would be the hdparm speed test: hdparm -tT /dev/sda and hdparm -tT /dev/sdb. It might be too quick to produce clicks though.

I had no problem telling which one was clicking as I isolated them by spacing them out on non adjacent trays and I also tried one at a time. W1H would click as soon as I booted the machine. As for connector #1 on mobo, I currently plugged drive 0GT to it and copied 420 Gb of data to it yesterday. There were no weird noises or errors. It only finished copying this morning, and I would like to test it tonight to make sure the data is ok. Any suggestions? As for when I receive the other drive, I will add it as Parity and see how it goes...
November 13, 200817 yr Author Yay...I have Parity!!! I got my replacement drive yesterday. Installed it, booted and added it as the Parity drive. Went through the Parity-sync for about 7 hours with no errors. After that, I did a Check Parity for another 4.5 hours. This morning everything looked good Thanks for all the help guys Cheers
