I would like to see some information from the disk, like
- relevant stuff from hdparm -I /dev/yourdisk (feel free to skip serial
number if you do not want to post it here)
- fdisk -cul /dev/yourdisk
- tail -fn0 /var/log/syslog / dmesg when the kernel detects the disk
for starters.
You need to use GPT if the disk reports 512 byte sectors to the OS. Thats
no problem, when its just a data disk. Try gdisk on the disk.
