lacie raid 1
i bought a Lacie raid1 and the box failed, easy buy another lacie raid1 and plug in the old drives, sorry lacie is not backwards compatable "this is a feature not a bug".
lacie support recommends installing one drive in a ubuntu 12.04 linux computer and using testdisk to recover data.
when i started i could see the linux array in home folder but could not read it. after a week of playing with testdisk, reading almost ever post in this forum, searching the internet and youtube i can no longer see the linux array in home folder but testdisk still sees it fine.
i still have my second raid 1 drive intact so im safe to play with the first one.
what do i have to do to made the raid 1 disk readable?
thank you for your time

Re: lacie raid 1
Please give feedback :
and if your disk is /dev/sdb, for each partition (/dev/sdb1, /dev/sdb2...) :
and also :
and last, but not least feedback (copy/paste) about what you can see with testdisk (Analyse/Quicksearch/Deepercearch) in different stages.
Code: Select all
sudo sfdisk -luS
Code: Select all
sudo mdadm --examine /dev/sdbX
Code: Select all
cat /proc/mdstat
Re: lacie raid 1
ok here is the log from testdisk the 3 commands do not seem to work. i did the search and the deep serach i hope this helps? thank you for your time

Re: lacie raid 1
There's an XFS partition detected, whose size is not far from 1TB. Your raid may be a Raid0 or a linear. Are you sure for raid 1 ?
Re: lacie raid 1
the lacie ships as a raid 0 i switched it to a raid 1 there is a rotory switch with an arrow on it, i changed it to raid 1 and i just checked the setting and it was pointing at raid 1 or safe 100 mode.
reading the manual if you switch modes it will delete the prevous settings, so that may be why the deleted raid 0 shows up.
here is the manual and page 54 has the setting

thank you for your time

Re: lacie raid 1
OK, and what about the two other commands (sfdisk -luS and cat /proc/mdstat) ?
After that, disconnect your disk, plug the other one, and give the same 3 commands.
