To whom it may concern. I have a problem concerning the Ethernet Big Disk (2TB). Recently I opened the chassis to remove both (1TB) HDDs and replace them with a smaller ones. Now from what I've known the configuration of disks was a RAID0 XFS file system. I placed two 500GB HDDs with the hope that the NAS hardware would create the appropriate RAID configuration and format to the appropriate file system. But it didnt! It wouldnt even recognized the HDDs, plus, i couldnt even logon to to the web management console. Im not sure what went wrong. I didnt try to put the original HDDs back on because i had already format them. Is there a way i could reset the hardware? Is there a tip you could tell me to get my NAS back working? Does it work with specific HDD models (Hitachi)/capacity? Regards.

Thank you for contacting LaCie Technical Support. Unfortunately the OS is stored on the drives you took out so you need them to get the unit to work. So you can't replace the drives in the unit.

ok..but as i already told you i formatted both disks. So that means the whole hardware is destroyed? how can i re-build it? is there a way to re-format the drives in that FileSystem and somehow re-install the OS? Sorry for asking you this, but, is this an efficient way to build something? I mean HDDs are common to mulfunction, so in this case the the whole hardware is destroyed? there must be a way to rebuild the whole thing. I thought that the OS was stored to a hardware memory rather on disk that way if something goes wrong with the HDDs, you just replace them.

Yes formatting it wipes the OS off the drive, you might be able to reinstall the OS on the drives or the other ones you are trying to use with instructions on this page

http://www.lacie.com/uk/support/drivers ... m?id=10099 I have never done this and we don't support how to do it, but that page I linked to is your best bet I think to get the OS back on any drives.
