Hi all, Need some help here. I'm trying to install linux on a Dell M1730 with Intel Matrix Raid # lspci 00:1f.2 RAID bus controller: Intel Corporation Mobile 82801 SATA RAID Controller (rev 02) The array is running a RAID-0 stripe on Dual Samsung SSD RBX Series 64GB Drives. These drives have an existing working Windows XP Partition that I plan on resizing for linux install. Problem that I have is that dmraid/fakeraid doesn't understand the array information. I've been following these guides: http://help.ubuntu.com/community/FakeRaidHowto which lead me to this page: https://help.ubuntu.com/community/FakeRaidDebug I have followed the guide, located the exact Array information sectors. Code: # dd if=/dev/sda skip=125045422 | hexdump -C | head 00000000 49 6e 74 65 6c 20 52 61 69 64 20 49 53 4d 20 43 |Intel Raid ISM C| 00000010 66 67 20 53 69 67 2e 20 31 2e 30 2e 30 30 00 00 |fg Sig. 1.0.00..| 00000020 7b b8 ba 07 e0 01 00 00 8f 66 c2 f8 a1 00 00 00 |{........f......| 00000030 f0 0f 00 00 00 00 00 c0 02 01 02 00 00 00 00 00 |................| 00000040 8f 66 c2 f8 00 00 00 00 00 00 00 00 00 00 00 00 |.f..............| 00000050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 000000d0 00 00 00 00 00 00 00 00 45 30 4a 38 31 36 53 45 |........E0J816SE| 000000e0 38 31 36 47 37 32 35 38 b0 0a 74 07 00 00 00 00 |816G7258..t.....| 000000f0 3a 05 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |:...............| Before patching, dmraid told me this: Code: ERROR: isw: Error finding disk table slot for /dev/sdb ERROR: isw: Error finding disk table slot for /dev/sda No RAID disks I then tried patching dmraid code per the guide. So the dd copied the last 1024 bytes, so 1024 / 512 (per sector) = 2. After patching #define ISW_CONFIGOFFSETS in the code (isw.h) and recompiling, I only get. Code: No RAID disks It had ((di->sectors ? 2) << 9). So unlike the guide had sectors from end for pdc, it just shifted di sectors ? 2. I've tried both (di->sectors ? 2) and 2. Neither worked. I've attached all the information I've found so far. One interesting node is that fdisk -u -l /dev/sda gives me no output. But the same command on sdb gives me the proper output. Other commands, such as dd, do work on sda. Please let me know how to proceed from here. Or if you need any more information. Thanks!
