[Goflex Home 3TB] Newbie help

[phdeez]

I think we need to add some info into the wiki about using the 3TB drive with the GoFlex... since a hybrid MBR is required and a lot more work is needed.

Some problems I experienced were:
1) My 3tb drive came from the GoFlex series with the USB3.0 dock, and the GoFlex Home I bought seperately. I initially followed the walkthrough but it did not work- at all. So, I resorted to connecting the drive directly to a Ubuntu machine and installed gdisk there. When I used gdisk to create the partitions it would start my partitions at 256 instead of 2048. I think this was my biggest problem.

2) I was using nc on my machine and when I performed a printenv it would print a page and then disconnect. I thought this might be indicative of a corrupted uboot install, or possibly uboot wasn't completly configured to boot.

3) I was really concerned about the drive reporting as 748GB when I did allow it to boot with nc enabled, however after reading ajblowing's post, I realized it was expected. I don't think I saw a post like that from the OP, or maybe I overlooked it. Because of this, I followed davygravy's walkthrough here but couldn't get it to work over tftp, I loaded it via a usb flash drive with fatload outlined here, which then cleared all my uboot settings, and required a serial connection. Thankfully I had a usb->serial cable (from my dockstar days ). (I used this page to figure out the defaults values for the GoFlex).

4) Honestly, the main reason I was doing all of this was to run the system from the SATA drive instead of a flash drive, which should be more reliable. However, I also didn't expect the drive to continue to run hot as it was on the usb3 cradle. Can others with the system installed on the SATA drive advise if their drive is running warm to the touch? I guess I'll try to run it from a flash drive and see how it goes...

Anyways, thanks for the posts and I appreciate all the knowledge here.

Installed the system on a usb stick, booted fine but 3tb drive still running in an active/idle state per hdparm (and hot). But, unlike when it was connected to the usb dock to a dockstar, the 3tb drive on the SATA port can be read with hdparm and more importantly, go into standby mode when not in use. (hdparm -y /dev/sda - run every 15mins to make sure it's in standby).

I guess I'll go with this, and the swapfile on another drive. Now I've got >5TB of storage on this device (3tb-SATA + 2tb-USB + 4g rootfs- USB Flash + usb dvd-r drive).

Hey all,

So I just got one of these Goflex Home box's and after reading several sites etc it seem I can get the use outta this thing using ArchLinux and SAMBA. (all i wanted is a big disk i can manage on the network, is that ot much to ask? )

So the thing i see is that the install guide isnt up to par for the 3TB drive (which i have) and I was wondering if someone has an easy guide to get this up and running.

Any help would be appriciated

Thanks!

You will need to prepare it with a GPT partition set with and MBR hybrid.

[ssjgohon]

Ah, is it possible to do so while following http://archlinuxarm.org/platforms/armv5 ... oflex-home ? or shoud that be done in another fashion

[WarheadsSE]

Make it with fdisk, just leave the partition to size: ~ 20G, then later you can come back and use gpt tools to convert the MBR to GPT & create the hybrid, I think. Once that is all done, a simple addition to fstab will mount the rest of your disk where ever you want it.

The guide really could use an update.

Stuck myself and trying to figure it all out myself.

At least please but a big warning on the guide saying it does NOT work yet with 3TB model.

Have you got USB flash drive working?

[war59312]

Yes but nothing happened when I connected it to the drive.

At the moment I have taken the drive apart so I can access via my Ubuntu 12.10 Boot cd.

Bummer:

You need to use gdisk, not fdisk. Fdisk only understands drives up to 2TB.
Also, don't specify partition number, you are partitioning the whole drive, not a partition
