[Goflex Home 3TB] Newbie help

[dikins]

Btw has anyone out there had luck with Goflex Desk (4TB)?
I’v tried almost everything from posts above to mount this 4TB usb drive but got nothing

Atm I have GoflexNet. ALARM is installed to 230 gb SATA HD.

1st of all I updated u-boot (according to this guide viewtopic.php?f=18&t=3355) and kernel to “linux-kirkwood 3.7.8”.

Some say it can help to solve mount problem for 4TB USB HD in theory (archlinuxarm.org/forum/viewtopic.php?f=18&t=4154), but not in practice (for me).

Secondly I tried to follow this advice (viewtopic.php?f=18&t=2611&start=30#p14953) to install ALARM from the scratch (to my 4TB USB disk). And again nothing.

More than that I can mount like everything (bootable usbstick, 1tb usb HD and so on ) but not Goflex Desk (4TB).

In conclusion I can tell that I’ve checked all possible options already (hmbr, gpt, mbr + gpt, hmbr+gpt, hmbr + hmbr, mbr+ hmbr, etc). The result is always the same…

What’s wrong with this drive?

PS There is a suspicion about some limitation of this hd. You can read about it here (http://www.everythingusb.com/seagate-go ... 21441.html) in «Breaking the 2TB Limit» section. Is «Advanced formatting» a must for alarm’s mounting?

hmbr IS guid+mbr. The thread was about hfs filesystem, not anything else. You only nwed hmbr to boot from a drive > 2tb. What filesystem did you use? ext4 will be no problem (with guid partition table, no MBR at all).

$this->bbcode_second_pass_quote('moonman', 'h')mbr IS guid+mbr. The thread was about hfs filesystem, not anything else. You only nwed hmbr to boot from a drive > 2tb. What filesystem did you use? ext4 will be no problem (with partition table, no MBR at all).

Again, the limk to doozan forum is about BOOTING from a 3TB drive, not just accessing it. The problem there is that U-Boo (the bootloader) does not support GUID, that's why hmbr is needed to boot from a drive that's >2TB. Once the kernel is loaded any drive should work as the linux kernel supports big drives. So you are running ALARM from a 1 GB drive, correct?

plug in your 4TB drive and run "dmesg". Show the output here

[dikins]

Ye, almost correct. I'm running ALARM from a 250 gb sata drive.

There's your problem. It is not because your drive is 4 TB, but because it refuses to communicate with USB controller on the plug. What I don't know is why. If you can get a different enclosure for the drive I would try that first.

[dikins]

Sounds promising
Btw the drive worked fine with native GoFlex Net.

[moonman]

Natively? You mean in the Net's sata port without the USB enclosure? Well, the plug doesn't like something about the enclosure then.

[dikins]

Nope I meant "before uboot installation"
More than that as I've already mentioned above $this->bbcode_second_pass_quote('', 'T')he drive is perfectly mounting under ubuntu (with the USB enclosure).

[dikins]

Well I have to confirm that ALARM (uboot?) can't correctly work with USB enclosure for Goflex Desk (4TB) (or maybe even with any USB 3.0 enclosure with external power adapter).

I've ordered SATA Extension cable to plug the drive directly to SATA slot (http://www.amazon.co.uk/gp/product/B001 ... UTF8&psc=1).

So let’s hope it will help to solve my mount problem
