I want to setup RAID5 on my system but I get some issues. I searched the web and tried to find the problem but failed to find anything.

My motherboard supports RAID 5, but in the ASUS manual I am directed to switch the SATA settings to RAID. Moreover, I don’t get the option of picking and choosing of the drives. When I change the setting to RAID, the Intel RAID setup utility comes after BIOS. I also made the RAID array easy. I don’t choose my operating system driver to be an array part. Everything seems to be good in the Intel RAID setup utility. Then I exit and after that nothing works, neither windows nor Ubuntu.

After that I want back to BIOS and changed the SATA setting to IDE and behold both OS work without error. Anyway, now I don’t have RAID. Another things happened that Disk manager in Win7 shows I have 9 TB on 3 drives otherwise it will be 11 or 12 TB.

In short, this is much more problematic than I had imagined, can somebody take me to the right direction.Onboard RAID 5 with a separate OS Drive


You may face the below problem.

  • You might have installed the OS and your Mother Board was in IDE mode.
  • If the above case is true then it will not boot in SATA mode or RAID mode.
  • As it was in SATA mode, so it will support only single drives.

Thanks for your help. I was able to successfully restore many critical files from a corrupted hard disk. Your product saved me a great deal of time and trouble. Thank Your Very Much!

I wanted to extend my ultimate gratitude and thanks to you and your team. Not only did your company recover the data quickly and at half the price of other companies, everything was recovered and our office is back on track after the NAS failure. I really appreciate a company doing its business so well as Disk Doctors did; and will definitely sing your praises for all to hear. Excellent customer service all around. Thank you again!

Many special thanks for your support in getting my drive issues handled. I am able to access all the files that were recovered. You guys are great!

I thought I was missing a folder until I realized I was searching under the wrong folder name.
I am happy! We are good and all is well!

Thank you.

What do you do when a power surge destroys your hard drive and you loose hundreds of hours of work, irreplaceable images, and your ability to complete jobs for clients with looming deadlines?  My first instinct was to cry, then scream.  My IT manager tried and failed to recover my data and recommended that I try a disaster recovery service. We went on line and called several companies, and when we reached the Disk Doctors, we knew we had found a company that could help us.  I delivered my toasted hard drive to their Vancouver location late in the afternoon and by 6:30 am the following morning a representative had emailed me with a reassuring message and time line for the work.  The following Friday I received one of the happiest calls of my life. My data had been completely recovered.  I cried and screamed again, this time with joy!  Over the last two days I have been thrilled, delighted, relieved, overjoyed and reassured by the fact that ALL MY DATA is once again accessible. Disk Doctors are now on my top-persons list and I am telling all of my colleagues about their services!!!

Thank you!

My hard drive crashed leaving me without my critical financial information and research that is crucial to my business. After checking various vendors on the Internet, I chose Disk Doctor Labs because of their level of service, and they far exceeded my expectations. Aziz Mirza, the manager of Disk Doctor Labs in Norcross, GA, personally took charge of my account, quickly fixed the problems and returned my restored files within a week on a hard drive that I could return for an account credit. Throughout the process, Disk Doctor Labs kept me informed, responded quickly to my calls and delivered my lost files quickly, efficiently and at an extremely fair price. I recommend them unequivocally.

Thank you!
