I should have thought of that. I have a Thermaltake BlacX eSATA+USB2
external "toaster", and with it gparted sees 3.64 TiB and can install a
GPT partition table. It takes 25 minutes to create an ext4 filesystem.
# gdisk -l /dev/sda
GPT fdisk (gdisk) version 0.8.4
Partition table scan:
BSD: not present
APM: not present
Found valid GPT with protective MBR; using GPT.
Disk /dev/sda: 7814037168 sectors, 3.6 TiB
Logical sector size: 512 bytes
Disk identifier (GUID): A69992CB-B312-429F-A287-093EE78B5AB5
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 7814037134
Partitions will be aligned on 8-sector boundaries
Total free space is 5070 sectors (2.5 MiB)
Number Start (sector) End (sector) Size Code Name
1 34 7814032064 3.6 TiB 0700

If my math is correct, with these drives a fully-loaded Backblaze would
have a capacity of about 133 TB. I'm also guessing it would weigh
something like 80 lbs.
