N4100+: hardware, firmaware or RAID5 configuration failure?

[itlity]

I have an N4100+ with 4 off 500MB HDDs configured in RAID5.

Over the 3-4 last months, I have had several rebuild operation due to a presumably faulty HDD.

This morning I decided to replace the suspected HDD and I did it using a brand new HDD of the same type as others already in use in my N4100+.

The NAS went immediately to a DEGRADED configuration and no automatic rebuild ever started -the green LED of the newly inserted HDD remained off.

I decided then to move back to the previous -suspected faulty- HDD and nothing happened. In parallel I received an email telling me that now the RAID5 configuration was DAMAGED.

I tried to come back to the factory settings and go for a file system check: I can ping the NAS from my PC at the 192.168.1.100 address but no way to get access to the login web page. My PC is configured at address 192.168.1.111 -I tried other addresses- and I used both HTTP and HTTPS with IE and FireFox -how desperate am I?

The NAS boots without an alarm, with an HDD or without. But now I have removed all the HDDs I had initially just in case something can be recovered: I do actually need these data as for a large part of them I have no backup.

Any idea about what I could try, at least to ensure the issue is with the hardware/firmware and my RAID5 configuration is still recoverable?

Dear Sir,

1.
If we remove any HDD from a running RAID, it is same with 1 HDD fail or out of draged already, and system would update RAID index count for every operation, thus if we pull and plug a HDD would make this HDD out of RAID.
2.
In RAID5 allow 1 HDD lose and showing DEGRADED, if showing DAMAGED means this RAID not working already, perpahs other out of RAID already.

Following suggestion steps for your reference:
1. Please update this N4100+ to latest version firmware & reboot.
2. Plug the ordionary HDD back to N4100+.
3. Download the CONF.BIN for us analysis for your, from: SYSTEM->CONFIG MGMT->DOWNLOAD->CONF.BIN
4. Sumit a ticket from http://esupport.thecus.com and provide the CONF.BIN for us to analysis for you.

Dear Yvon,

I have similiar problem!
Just received the 4100+ yesterday and am installing RAID 5 configuration with 4 TB HDD.
Whenever the installation is finished (after 5 hrs), the RAID Information showed:

Raid 5
Total Capacity 2,812,344 MB
Status Degraded
Used Percentage 128 MB (0&#37
Strip Size 64KB

.

As far as I know, the Raid 5 Configuration with 4 TB HDD should result in 3,8 TB.
My HDDs are SATA II Seagate Barracuda, 7200.11, 1TB, 32MB Cache, ST31000340AS.

I have reconfigured the NAS already threee times and always the same failure - 2,8 TB for 4TB HDDs.

Kindly ask for suport!

Thank you.

Dear Sir,

Every Thecus NAS been passed the burning test before shipment, thus if system degraded constainly, we could via SEAGATE' seatool to verify HDD health status first:

Dear Yvon,

How can I check the HDD via Seatools, since they are intalled in the NAS?
I have already replaced the HDD in their slot position and always the slot II HDD was not used to build the Raid 5.

Best,
John

Dear Sir,

We need install HDD into PC and than via SEATOOL to diagnosis the HDD with any abnormal parts or not.
