Thank you for contacting Intel® technical support. I will be more than happy to help you.
I understand that you are having issues creating a RAID 5 volume in your system.
Regarding the size detected for the drives, this is happening because there is a chipset limitation that will allow you to use only up to 2 TB under special circumstances like this one.
To create a RAID 5 volume in your system, I would recommend you not to do it with Intel® Rapid Storage Technology. Please do it with Intel® Matrix Storage Manager, which is fully compatible with your chipset. If necessary, please update this tool. You can download the latest version using the next link: https://downloadcenter.intel.com/download/17882
As a possible workaround, you can try to create the RAID 5 volume using the Intel® Option ROM tool. To access this tool, reboot your computer and press CTRL+I when requested.
I have the following comments:
- You are aware of the fact that the applicable SATA ports on the X58 ICH are only SATA II (3Gb/s) capable, right? It is possible to get add-in RAID cards that will provide SATA III (6Gb/s) performance.
- Your motherboard may provide additional SATA (or eSATA) connectors. You cannot use these for RAID. I am just saying, make sure you are using the right connectors. If your board doesn't have any others, no need to react to this comment.
- For Intel's Desktop Boards that utilize the X58 chipset, the version of RST recommended/supported varies. Early boards used v10.1.0.1008, while later boards used v220.127.116.112 (I presume this is to match up with the version of the RAID Option ROM that is included within their firmware (BIOS)). You can download these versions here and here if you would like to try them.
- In order to use drives that are larger than 2TB - and be able to use the RAID Option ROM to create RAID array(s) - you must enable UEFI support in the BIOS. Now, doing so will also likely require that you reinstall Windows 7 (so that it can be booted in UEFI mode). In this case, during the Windows 7 installation process, make sure you delete *all* partitions created on your SSD so that its partition table can be recreated using UEFI (GPT) partitioning.
[Aside: For safety, I *always* delete all partitions and then tell the Windows installer to install to the drive's free space (which is all of the drive at this point). This allows the Windows installer to own the partition creation process and control the number and size of the partitions it creates.]
- It is unclear (to me) why it denied RAID5 array creation at runtime. This may be because of the (non-UEFI) limitation at the BIOS level - and I agree that this doesn't make sense - but, well, sh1t happens...
Hope this helps,
for the points you mentionned...
- Yes I am aware of the SATA II limitation of the board, it's a pity that it doesn't have SATA III, but performance isn't really bothering me. I mainly wish for a minimum of redundancy, but I can't afford to make it a RAID 10...
- I have verified the ports, and made sure they are all on the same controller, not dedicated to eSATA or anything else, even tried to change the ports in case I was wrong, ( did port 0 to 3, and 2 to 5 ) , went in the BIOS as well and made sure they were all set the same.
- for the 2 versions of RST , I tried so many, I passed though the ones HP had, and some from intel, I will give it a go as well as those given by Xavier in the earlier post.
- there are no UEFI options in the BIOS ( some motherboard have a 'compatible' mode for it, or simply straight up switch to UEFI, but this one doesn't seem to have it )
Yes it is a sh*tt* situation, as it is supposed to be compatible, I also switched over to a Windows 10 yesterday, hoping this might help, but for now, the same issues persist.
I'll make some more tests tonight,
