Hi everyone,

We've recently ordered connectome in a box and have been having some
trouble accessing the data on the disks. The disks did not appear to
have valid partition tables on them which could be recognized by our
linux servers, and I was wondering if I could get some details from
anybody who might know more regarding the partition scheme (GPT?), and
how data is configured across the 5 disks.

We've installed them in our RAID array and tried to bring them online as
individual disks using a trivial raid 0 configuration (since raid 0 on a
single disk should just be the same as a non-raid configuration). The
disks became visible to our operating system but no partitions were
detected (i.e. we can see /dev/sdc but not /dev/sdc1 for instance).
Various disk partition management tools (fdisk, gdisk, parted, gparted)
all complain about corrupted or invalid partition tables, and this has
all been the case for both of the two disks I've tried of the five.

If anybody else has had similar experiences or has any useful
information to share I'd appreciate it. All I've found on the connectome
website are instructions to hand this to our IT person (me, in this
case) and that the drives are formatted with EXT3, neither of which have
helped.

Thanks,
