Hi,

there was an upgrade available online and when the computer was upgrading my connection got lost and now my computer can't locate the seagate central device.

I think that the interrupted might have rendered my hard drive inoperable.

Is there anything I can do?
I hope somebody can help me...

First off, it would help if you posted a bit more information. Can yo give the drive model number, link to it's product page maybe, and what software you used to do the update?

Most firmware updaters will not start the update until it has the whole file stored locally and did some sort of hash check before proceeding with the update. Same goes for NAS-type drives. They'll first retrieve the whole firmware file and check it before starting the flashing process, making internet issues unlikely to have caused an issue.

Can you remove the drive from its enclosure and test it on a SATA port? Start with a SMART report. This will tell us the physical state of the drive. Note that the file system will most probably be a Linux type, in which case you could try a Ubuntu Live CD or Linux Reader for Windows.

I think the OP is talking about the Seagate Central drive (STCG2000100)

The drive has a web GUI and he most likely started the firmware update through there.
