There is no update for the CC1H series.... I'm going to hold off upgrading the SD1As until I hear more feedback on the SD1B firmware.

Updated 6 1.5tb Seagate drives with SD19 to SD1B today with no problems. I had no problems with SD19 either but figured I ought to go forward before my 30 day return period ended. If I bricked any of the drives I could still return it.

50% success rate. Guess that is the optimistic side of me. Out of 6 drives now, I have found 3 to stay good for more than 40 hours. The 6th drive CC1H factory is crapping out with 2 reallocations so far. This was the RMA'd drive already.

Fortunately, when I shoved the latest drive in the fourth slot tonight, I got this message:

Found free space to expand the volume onto, but expansion cannot occur with an active snapshot. Please disable the snapshot at your convenience, then either reboot the system or reinsert the drive to begin expansion.

I take that to mean no volume expansion has occurred, and I am still happily redundant with the 3 disks that happen to tell me they are still okay. Any Jedis verify that this is the case? If so, Peace of Mind, until I find a 4th happy drive.

I got 3 1.5TB drives in my Pro (2 made in Thailand, 1 in China) with two of them having some reallocated sectors (15 and 6) after 'scrubbing'. All on firmware CC1H.

I also got quite a few high fly writes, but I'm not sure that's even meaningful to report - I thought only WD was actively using that counter.

More importantly, the NAS is still being reported as fully redundant and as long as none of the drives fail, I'm not going to change anything with what appears to be hit&miss firmware. I guess adding a hot spare would be a smart thing to do, though...if only someone else had a 1.5TB drive out!

I actually have a ST31500341AS I got about 10 days ago. I am getting a ton of smart reallocated sector count errors but the interesting thing is that I have the same number of reallocated sector count errors as I do power on hours. And they are keeping in step. It looks to me like there is a bug in the CC1H SMART code that is pulling the realloc count from the wrong place.

Can anyone confirm this? Does anyone have a link to the CC1J firmware as well?

Thanks

I have one CC1H in my ReadyNAS X6 running 4.1.4 and I see
Model: ST31500341AS
Firmware: CC1H

Spin Up Time 0
Start Stop Count 4
Reallocated Sector Count 4
Power On Hours 325
Spin Retry Count 0
Power Cycle Count 4
Temperature Celsius 42

As you can see for me it doesn’t match the number of power on hours. It does match the start/stop count and power cycle count but I think that is coincidental because I’m sure I have seen those with different values.

My latest is the drive that replaced my failed one has failed, >500 reallocations in 31 hours of power time. No correlation of hours to reallocations for me. This one is on its way back today.

Just got my Pro and loaded a single 1.5TB Seagate into it (came with CC1H firmware), decided to go with it as shop has a no questions asked 30 day return policy and I needed a drive to test out the box so seems like an excellent opportunity to work with the 1.5TB drives and work through the setup for the Pro.

The drive was built in Thailand with a part number of 9JU138-336 and came loaded with the CC1H firmware, date code is 09294.

After about 12 hours of running (loading fully backed up non-sensitive data) no errors yet. Keeping a close eye on the smart tab for the drive.

An off topic question, I have the box directly connected to the PC and I am getting about 20mb/sec write rates to a single disk. I don't know if I am readynas Pro limited or PC limited (the data is coming off two USB attached drives). Just wondering if anyone has some performance numbers for a single drive setup.

I usually get about 20~25 MB/sec from USB connected drives (that's why I switched to FW800 where I get about 64 MB/sec)....that's with the 1.5TB Seagate drives.

Update,

2x CC1H firmware drives have reallocated sectors now. one has 1, the other has 9.
2x SD19 firmware drives have 0 reallocated sectors after a week and a half.

Ordered 2 more drives from Newegg on Tuesday to replace the 2 CC1H drives. New drives came in.... also CC1H. I haven't even pulled them out of the bag, sending them back un-opened.

Ordered 2 more drives from Amazon yesterday, the first showed up today: PN: 9JU138-301 FW: CC1G (that's a new one on me and I'm not too thrilled)
The second new drive from Amazon hasn't gotten here yet. I think it came from a different warehouse though so that's a promising sign.

So anyway, at this point, I have 8 1.5TB drives. 2 working great, 4 going back.

Has anyone heard of the CC1G firmware?

Is there a confirmed update for the CC1H drives? Looking through Seagate's support articles, they still say that CC** drives are fine. When I run my serial numbers through their system, it says that all of my drives are up to date.

What I find interesting is there appears to be two issues:
1) Drive quality - As far as I know the firmware updates have nothing to do with reallocated sectors, but of course that is a guess because Seagate aren't really telling us what they are fixing
2) Firmware issues, Drives freezing, Bricked drives etc

Interestingly, my three drives with SD firmware have had zero issues to-date but I am seeing reallocated sectors on my one CC drive. Reading through this thread it appears that there are more reallocated sectors on the CC?? drives can others confirm? It would be interesting to tally how many reallocated sectors people have seen by original firmware and the number of hrs of uptime.

So I have:
Quantity: 3
Orig Firmware: SD17 (Upgraded to SD1A)
Reallocated Sectors: 0
Hrs Uptime: ~1000 hrs each drive

Quantity: 1
Orig Firmware: CC1H
Reallocated Sectors: 4
Hrs Uptime: ~600

Probably would have been better to collect in a table but I couldn't get it to post correctly.
