bohmwu Posted October 19, 2012 Share Posted October 19, 2012 Just purchased the N40L from buy, received well, first tried win7, nice and decent, however, I need many php and java service, therefore the best way is using linux, or in other words, ubuntu, which is my best choice, I am not expert, and very lack of knowledge. ubuntu was successfully installed on the 250GB hard drive, i had 4 x 2tb, and I set them up as RAID0. in the win7, it worked as it should be, and i used GPT for them. but in the ubuntu, it was been told there is a Raid, and need be activated, i chose yes, and it shows only 1.4tb (with something mapped-h.....), which should be 8tb or at lease 7.2tb in windows. when the installation was done, I couldn't find the location for the series of raid. or because my little knowledge for linux? /dev/sde or else isn't available tried fdisk to check.. like below root@ubuntu:~# fdisk -l Disk /dev/sda: 2000.4 GB, 2000398934016 bytes 256 heads, 63 sectors/track, 242251 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xa6ee4e1b Device Boot Start End Blocks Id System /dev/sda1 1 4294967295 2147483647+ ee GPT Partition 1 does not start on physical sector boundary.

a15457 Posted November 21, 2012 Share Posted November 21, 2012 Not knowing anything about ubuntu what I'd try is re-installing win7, delete the RAID 0 partion (7.2TBish), blow away Win7, re-install Ubuntu and see if it picks up the 4x2TB disks properly. If you already worked this one out I'd love to know how you did it. Link to comment Share on other sites More sharing options...
