(solved) Dockstation for SATA HDD not recognized; how to make it working?

[floppy]

Hello,
I have received the dockstation -- Xystec Klon-Festplatten-Dock "DSU-3525.Copy" für 2,5 & 3,5" SATA-HDDs --.
a) With CoreLinux 4.3, when I connect it (with a 500GB HDD in it) to an eSATA connector of a PCI card, nothing is recognized with mntool (no new message is seen in dmesg).
b) When I connect the same dockstation with HDD in it, to an USB connector to my PC, dmesg show:
...

which is better than a). When I click on "Refresh" of the mntool, I see the dockstation try to be contacted, but dont appear as new sdx in mntool. I think few modules are missing for recognizing the dockstation.
So, can somebody help and inform how to make it recognized with corelinux?
I will further search but any quick advise is welcome.
My first target is
a) use that dockstation and connect the HDD 500GB to my PC with eSATA
b) format the HDD with ext4
c) put all data on it
d) create 1x per month a backup with that dockstation

The "sdc: unknown partition table" may just be because it has no partition table, it should be ok to create one on sdc if it has no data. Use fdisk or one of the extensions.

On the eSata, did you connect it with the power off or when running? Maybe something doesn't support hotplug, and it needs to be connected offline.

gparted will do it?

I made the power on at the dockstation (with the HDD in it); then switched the PC on. So there was no hotplug. I will make an hotplug event later (switch the dockstation on when the PC is already booted) and will post any result. For the reason this is the first time Im using it, it could be an HW issue (but the dockstation is new).

Yeah, gparted is ok.

Yeah, gparted is ok.

the HDD in the dockstation is recognized now in case of connection with USB (I created a MBR; ext4 format; with gparted).
The HDD is sill not recognized with the esata connector (which is on a PCI card):
- in case the dokstation is connected before PC boots: nothing
- in case the dockstation is switched on after the pc is booted: nothing
I will further dig in the subject.
eSATA driver not ok for that card? (I've seen different issues in the internet regarding eSATA drivers in the kernel)
Connector issue? Dockstation issue?

Check your SATA card manual.  You may have to jumper the SATA port to use the ESATA connector instead of the internal connector.

yes sir. Thanks. The HDD is at the eSATA connector now.
