N7700 Problems with 1.5TB Seagate
Herewith a copy of a message I sent to Thecus - Yvon today 10th November 2008, and the response I had from Yvon a short time later, plus further information I have collected from the web.
Yvon
You were most helpful ref the problems I had with my N5200(see N5200 smoke).
I now have a new problem as a result of purchasing your latest N7700.
Product:N7700 V1.0844306, purchased from Scan in the UK. 5th November 2008
Firmware 2.01.04
I purchased 8 1.5TB (Seagate ST31500341AS - BARRACUDA 7200.11) hard drives (firmware SD17)from Lambda-tek UK at the same time.
I fitted 7 of the drives, and created 1 raid 5 array using 5 of the drives, the other 2 being marked as spares.
Creation was unsuccessful.
I then decided to reformat and create a smaller raid 5 array using just 3 of the 1.5TB drives, this worked and I then set about loading some test files onto the raid. I found that the process of loading was stopped at about 25GB of information. The files were about 700mb in size, and appeared to be there. and showed up the the folder, sadly when I tried to use the file(an avi file) it stopped part way through, and the raid showed error as a degraded raid and a red disk light was showing on one of the hd's.
I have tried this several times, but with no better results.
My question is:-
1. Shall I return the unit as faulty to Scan and ask for a replacement.
2. Shall I wait for a firmware update?
3. Shall I ask for a refund?
I am dissapointed that the unit has been designed with an apparent upper limit on Hard drive size. I also suggest that you do not use the review by Eaegis http://www.thecus.com/news_contentx....49e8db8dd915b8 on your news page as this suggests that your N7700 will give a capacity of 10.5TB, this is only possible if your unit works with 1.5TB hard drives.
Looking forward to your reply.
Regards Chris Sherwood

Dear Sir,
In recently we get some feeback about 1.5TB for your reference:
1. We just get the 1.5TB in recently, and found this HDD get HDD SMART warning easily, thus why we didn't list this HDD on the N7700 HDD list.
2. Some forums in Asia talking about the stabilility issue on this HDD.
Every NAS shipping from Thecus both passed the factory quality testing, but current we worry about it is realted the HDD, thus if possible would you please try with other HDD as like 1TB or below to verify it is HDD related issue or not.
Also Thecus via this fourm to reply users enquire, if somthing need the support from Thecus offically, it is welcome to conmtact with us from http://esupport.thecus.com.
Yvon.

Again Yvon has been helpful, suggesting things to try. Since thecus have cast doubt on the quality of the 1.5TB Seagate hd's I have found the following post.

I am looking forward to resolving this soonest, and am not giving up on this just yet.
Best regards Chris
Re: N7700 Problems with 1.5TB Seagate
Chris, Please keep this thread alive and update us with your findings.
I ahve two of these N7700 on order, and 14 of the seagate 1.5TB drives waiting for these NAS boxes.
NO one has been able to get them to work, no one.
Thats terrible news. I hope Thecus solves this problem, and I hope Seagate solves their firmware/disc cache and journaling problem.
I have 5 of these in Raid 5 in a N5200PRO with no problem, for one month now

Dear Sir,
Following HDD list we tested on N7700 for your reference, on theroy the N7700 could working with Seagate 1.5TB HDD, but current we worry about the 1.5TB HDD would get some problem even on PC or other NAS, thus current we do not recommend using 1.5TB HDD.

Re: N7700 Problems with 1.5TB Seagate
I have 6 of these HDD´s and phoned with the Seagate-Support to discuss this problem:
A new firmware will be appear next week!!!
But will this fact resolve the problem with the new N7700...? I don´t know.
I have sent back my new N7700 to my reseller and waiting for the next two
firmwareupdates before I will buy another N7700 with 1,5 TB HDD´s or the next
generation of Hitachie HDD´s (2 TB).
Best regards

Re: N7700 Problems with 1.5TB Seagate
Rainer, Please send that firmware to Chrisjsherwood... and see if he can get 7x 1.5tb drives to work in his Thecus N7700
Thanks guys
Re: N7700 Problems with 1.5TB Seagate
Dear All,
Recently Seagate release new firmware for HDD, and we would arrange a long term testing to verify this 1.5TB HDD stability & durability too, thus current we don't recommend using the 1.5TB HDD on N7700, in necessary please choose the HDD from the N7700 HDD list, we would update the test result since we confirm the compatibility, and thank for your patience in advance.
