Seagate Expansion Desktop 4TB STBV4000300 not recognised?

Postby cam » Thu May 30, 2013 3:06 am

Hi,

I just bought an External hard drive Seagate Expansion Desktop 4TB model STBV4000300 and found out that it is not recognized as External Hard drive in the latest DSM 4.2-3211.
It is not listed in the http://www.synology.com/support/faq_sho ... 4&lang=enu or http://forum.synology.com/wiki/index.ph ... ernal_HDDs

Using DS411+ and connecting the Seagate through USB port.

Is there any reasons? technical issues? or?

Thanks,

Hi

No reason other than the DS USB interface properly don't recognize the USB3 chipset used in the Seagate.

What to do, wait for Synology to get it into a new DSM version.

Sometimes the DS has problems with disk that is formatted in non EXT4 filesystems, like NTFS, and the DS cannot see the disk.
You could try to format the disk into EXT4, from a linux disto.

Hi,
Thanks for the reply.
The disk was indeed formatted using NTFS. When plugged directly to the Synology, it was not recognized.
I plugged it to my MAC, and managed to see it mount. I formatted the disk using Mac OSX Journaled filesystem, unmount it and connect it back to the Synology. Still the same: not recognised.

Hopefully, they will do something about it...

Hi

The MAC file system is not supported by Synology!!

You could try to boot from a Linux CD and then format the seagate to EXT4, which is Linux native fileformat

I also have the same problem. Can someone advise where to get the patch. I read that Synology remotely logged into someone's system and installed a patch. I have a 1812+ and tried to connect my USB 3.0 Seagate external 4tb drive to the 2.0 and 3.0 usb ports but it doesn't see it. Help!!! :(

Same issue here. I moved from Thecus to Synology because of these problems. Now I am horrified to find that my Synology DS1812+ isn't recognising external drives!

What to do about this?

Is there anyone from Synology here reading these threads?
What is the best and fastest way so that Synology addresses this problem?

I understand that this is a user forum, and I will post a query to Synology. Wouldn't it be easier however for Synology to input into these forums instead of each individual user having to send an individual description of essentially the same problem?

Fixed - contacted Synology and they send me a DSM update that disables some check, allowing the drive to work. The NAS reboots after the update, and the external USB drive appears under Diskstation as Usbshare1.

Wow, we're having the same trouble with the same external Seagate drive (we're on a DS412+ however).

We just called the Synology tech phone line and they seemed bewildered and scared and unable to help (pretty much like every other time we've phoned), so can I ask - what update to the DSM did they send you? We seem to have the latest one installed which is vDSM 4.2-3211.

Cheers

Martin

Hi All,

I am encountering the same issue with a Seagate Backup Plus 4TB USB3 drive (model STCA4000100) on our DS1512+. When I contacted Synology tech support, they said my drive wasn't supported as it was not in their blessed list here: http://www.synology.com/support/faq_show.php?q_id=443&lang=us

This despite an almost identical drive being in the list: Seagate GoFlex Desk 4TB External Drive USB3.0 4TB (model STAC4000100) which appears to have been discontinued. Anyone have any luck getting these newer large TB drives working on their NASes?

Cheers,

Nick

In case this helps out anyone else, I have managed to fix this on my own by following the steps in this post:

http://forum.synology.com/enu/viewtopic.php?f=226&t=67821&p=267380&hilit=external+drive#p267380

The drive came up just fine and I was able to get a backup task running no problem. I should note that I had the drive formatted as EXT4 before hooking it up. I am also running the latest DSM of 4.2-3211.

Hi Zonks,

Would your posted solution work for an esata drive?
What would be the correct command instead of usb_storage?

thanks

zonks, I had to chime in here and compose my very first post as a new sign-up to express my sincere thanks to you for this invaluable info. I have two 4TB versions of the Seagate and couldn't for the life of me get it to be recognized by the DiskStation. But after formatting to EXT4 the dang thing took and now I have over 7TB to play with in addition to the internal storage!!!! Didn't have to go out and buy more expensive external drives! Synology rocks and so do you for posting this. Thanks again!
