Seagate 3TB ST3000DM001 and 2TB ST2000DM001 Compatible?

[marshalleq]

Yep sorry, it was capacity expansion, I couldn't remember the terminology. There is a warning in the web tool I think saying that all data would be wiped. The point the ODOM makes around having partial data backed up is a valid one for home NAS unfortunatley. Ultimately, there is no solution in most peoples budgets to back up what can currently be up to 16TB of storage. Clearly he does what I do, and backs up things like music, documents etc, but any large files (like dv editing etc) you're pretty screwed. Upgrading RAID is a risk, but backing up that much data is expensive. Cheapest option is probably to get a whole other NAS with some live replication going on and that aint that cheap either.

ODOM, if I understand you correctly you have the exact same situation I have had except your 2TB drives are a different brand (I'm running the Seagate green ones). If you can initiate an expansion and hot plug your 3TB in place of one of the 2TB's and it starts to rebuild then you will be one step further than me. The one point I'll make is that I updated my firmware on the drive to latest before trying the expansion procedure. I'm suspicious it was that that prevented it from rebuilding, though I don't know. I am tempted to try a few different way's of wiping the drive now, though I'm pretty sure I did that already.

Also will probably update the firmware in a minute, but I assume it will be the same changes as in the other NAS's with same firmware which doesn't seem to list anything affecting this that I can see.

I'd be interested to see what happens with your setup as I'd really like these drives to work!

ODOM I see you just posted while I was writing

Are you saying you've gotten one 3TB drive to be accepted into your RAID array? Don't open those drives until you have.

Just got an update.....my QNAP has been shipped back to QNAP for repair/replacement. Hopefully I'll know soon enough if it's the drives or the NAS

[marshalleq]

I take it you don't ship it back with the drives when it goes back? Its making me wonder what happens if they say it's the drives and seagate says it's the NAS...

[marshalleq]

And now running 3.7.3 if anyone has any questions...

[marshalleq]

Came accross this other article with these drives which states that in this case a drive isn't added to the array until you run a bad block scan after updating the firmware. viewtopic.php?f=25&t=62046

Correct, only the NAS was returned.

I haven't done anything yet, no. My current specs are:

TS-459 Pro
Firmware 3.7.1 Build 20120615
Hard Disk Model Hitachi HDS722020ALA330 JKAO
Model Number Hitachi HDS722020ALA330
Serial Number JK1181YAJ1Y06V
Disk Capacity 1863.02 GB
Firmware Version JKAOA28A
ATA Version ATA-8
ATA Standard Not recognized. Minor revision code: 0x29

I have 4 of those Hitachi 2TB drives. I don't use green drives in the NAS, as I keep reading about problems with them when used in RAID arrays (not only in QNAP devices).
These are 7200RPM drives, pretty quiet, and at the time cheaper than the competition.

I now wanted to replace those drives with bigger ones. The 4TB are almost impossible to find here and still too expensive. Due to floodings two years ago and hard drive companies being sold and bought, there isn't much choice in 3TB drives running at 7200RPM, and also finding them in stock . For years I keep reading about firmware issues with the TB Seagate drives, so I never went for those. For now, I didn't have any other choice. The compatibility list says the drives are OK as long as they get the latest firmware update.
So, I bought 4 of these 3TB Seagates ST3000DM001. The sticker on them says they have FW CC4B.
I opened one of them the other day and after plugging it in internally, the Seagate Tools tell me it has CC4H on it. So I guess the stickers are not correct.

When I read this thread, I though there were issues with the latest QNAP firmware 3.7.2 and/or higher. I hadn't applied the update yet, but didn't want to do it and then have issues with these drives.

So, I suppose tonight I will try to update my NAS to the latest firmware, reboot it and then replace one of the Hitachi drives in my RAID5 with this Seagate one. Let's see what happens. I suppose it will take about 24h to rebuild the array. I can then report back here what happens on the box and what my QNAP recognises for the drives. If there is a problem, I can always stick the other drive back in.

Thanks for your reply. I am very familiar with RAID, but I probably asked the question in a wrong way. What I meant with "known issues" I meant in relationship to these particular drives (these Seagates and the firmware).

I have only read that allegedly the problems (except they still chirp) should be solved with the latest Seagate firmware and Qnap firmware 3.7. Hopefully that's true.

I am aware of the difference between backup and hardware fault-tolerance (I also preach this ), but I lack the economic means to buy two QNAP NAS's with 6x 3TB drives (these babies are very expensive in Germany for an average consumer to buy) so I can have a full backup of everything.

Well as long as you understand that difference I'm satisfied. It's your data and your risk, so you decide how you want to spend the money between main storage and backup.

Personally I don't like to gamble and I prefer less storage and having the ability to keep multiple backups of everything.

What do you mean by "chirp"? Making noises? If that's the case, I'll see it (or rather hear it) tonight, and if so I'll return them straight away. I have my NAS in the living room and with the Hitachi drives you hardly hear a thing. Let's wait and see

I had considered buying another NAS and put the new drives in that one, then just run a replication job between the two. But the newer models are quite a bit more expensive and very hard to find here. If I manage to find them online, then they are usually not in stock.

I received today another 3TB ST3000DM001 and it already has the firmware CC43 on it. The drive select tool tells me that there is no newer one availiable. So my question ist: Ist CC43 newer then the CC48?

According to the Seagate site the latest Firmware for the ST3000DM001 3TB drives is CC4H:

Yes, as reported here and by others in the forum as well.

Seagate failed miserably with the Seagate Barracuda Green 5900 rpm disks, ST2000DL003 (some of the problems with them are described in the forum). As far as I understand it, they then changed their policy to not offering slow spinning disks any more but claimed their new 7200 rpm disks (the subject of this thread) was almost as power frugal. To achieve that marketing promise they had to employ an aggressive power saving scheme and apart from not working in NASes (exactly as the infamous ST2000DL003) they also made a lot of noise that customers didn't expect/want. As far as I know the new firmware should now make the ST3000DM001/ST2000DM001 acceptable in a NAS but according to the thread I linked above, they still make those sounds.

Interestingly enough Seagate, after aquiring the Samsung disk business, now offers the ST2000DL004 that is a rebranded Samsung HD204UI, a slow spinning disk that have a much better reputation in NASes than the Green disks from Seagate and WD. Even more interesting is that I can't find any documentation of that rebranded disk at the Seagate website, so maybe they're a bit embarassed about their own products failing but still want to cash in on Samsung products...

If that's the case, I'll see it (or rather hear it) tonight, and if so I'll return them straight away. I have my NAS in the living room and with the Hitachi drives you hardly hear a thing. Let's wait and see

I love my Hitachi HDS722020ALA330 also. They have served me well for several years and are still working.

Hitachi may be a bit more expensive than WD and Seagate but they seem to work very well in NASes. Let's hope that WD allow them to continue...

Interesting information, thanks!

I now upgraded my NAS to FW 3.7.3 Build 20120801.
I pulled out HDD Nr. 4 and replaced with a Seagate 3TB. It's been 10mins and the rebuilding is at 3%, so it's going to take a while.
My NAS shows the following info for it:
Hard Disk Information
Hard disk model Seagate ST3000DM001-9YN1CC4H
Model number ST3000DM001-9YN166
Serial number W1F0WN9F
Disk capacity 2794.52 GB
Firmware version CC4H
ATA version ATA-8
ATA standard Not recognized. Minor revision code: 0x29

So far I don't hear any strange noises, nor "chirping".

This I know Odom, thanks anyway. What I meant is:

I have 4 disks. 3 with firmware CC4B. These have surely an older firmware then CC4H.
But is the firmware CC43 also older then CC4H?

How do the count? CC4A, CC4B..., CC4Z, CC41, CC42...
or
CC41, CC42,...CC4A, CC4B... ?
