How to remove remnants of RAID from HDD

post #1 of 2
Thread Starter 
Hello all,

I ran into an oddball issue and thought I'd share how I resolved it. I decided to use one of the drives from a RAID1 in old PC as storage drive for a new build. I formatted the disk before I installed it, but noticed it showed up as "Intel RAID1 volume". Also Intel Rapid Storage Technology GUI was reporting an error and not showing the storage disk at all.

Through reading on the internet, it seems that the RAID information is stored in the metadata and a "regular" format does not remove this. However, I was able to fix this without harming the data by following the steps below:

Disclaimer- I'm not a HDD expert, but this worked for me. I backed my data up before trying this(just in case) and highly recommend you do too. Everything you do is at your own risk!

  • Make a Parted Magic live CD

  • Boot from said live CD
  • Open up "Partition Editor". Use the thumbnails to get the disk name for drive with the error. Mine was /dev/sdb.
  • Click the black computer monitor icon on the bottom bar to open a terminal window.
  • Issue this command
Code:
sudo dmraid -E -r /dev/name_of_your_disk

  • Answer yes on the prompt
.

This took about 2 seconds to run for me and after I rebooted, the correct "disk driver" was installed and everything showed correctly.

Also, you can use disk part and run the "clean" command.
