" rel="nofollow - I am a bit of a rookie when it comes to RAID and I think I messed up big time. My roommate and I built a PC with an ASROCK x99 exteme4. He installed RAID5 with 4 HDS. Recently I was having trouble getting the computer to boot. It would start for 20seconds and then turn off with no video output. Irrationally I thought I could remove the CMOS battery to reset BIOS and get the computer to boot. Which it worked but now my RAID 5 is missing. I can see all the hard drives in the BIOS and RAID Utility but the raid is not bootable. Did I screw up an loose all of my data? I am thinking about updating the BIOS with the latest update from ASRock. I am lost, hopefully someone here can give me some guidance. |

Did you go back into BIOS and set the HD mode back to RAID, it defaults to AHCI on reset. I have not messed with raid in a few years but usually if RAID 5 fails it is due to one HD failing (causing boot failure), or the raid config getting corrupted. Usually you can recover/rebuild the raid 5 array if one HD falters but you need to know if it is an HD failure. You should check the HDs with a bootable cd/usb from the HD manufacture. The other thing is odd that it shut down after 20 secs... Usually there is a boot failure warning or it goes straight to BIOS if no bootable device found. Maybe someone else here has a better info ------------- https://www.passmark.com/baselines/V9/display.php?id=99573335296 |

" rel="nofollow - Yes, I did set the HD mode back to raid after I was able to start the computer back up. I do not think that any of the HDS failed, I can still see all of them in the disk management and in the BIOS as well. I do have a separate SSD for booting and progams so I am able to use the PC currently. I think by resetting the BIOS is seperated the RAID5, which is made up of 4 disks. When I look at Disk management I have two disks still in the RAID5 and the other two disks are outside of it. Anyway I can get them all back together? Any tips on how to try and recover the data? |

" rel="nofollow - this forum poster got his RAID working again, might be worth looking into: http://forum.asrock.com/forum_posts.asp?TID=8502&KW=raid&PID=50427 ------------- https://www.passmark.com/baselines/V9/display.php?id=99573335296 |
