Fixing a broken mirrored Intel Matrix RAID-1 machine

Posted by jpluimers on 2018/04/20

A while ago I had an Intel Matrix RAID-1 pair of drives that got broken. One of them turned “red” and – since both drives were only a few serial numbers apart – the other was giving issues the moment I tried fiddling with it.

These actions failed:

  1. Windows image backup – would end up with a “blue” screen indicating Windows 10 had a problem and was trying to collect data
  2. Paragon HDM
    1. Migrating the OS to a brand new RAID-1 set
    2. P2V
  3. Disk2vhd would hang at the 100% completion mark

What had succeeded was a regular Windows backup (a non-image one).

This is what I finally did to get it working again:

  1. Kill disk2vhd after it hung a few hours at the 100% completion mark
  2. Verify with
  3. Mark the VHD file as online using diskpart (first atach the vdisk, select disk, then mark it online)
  4. Verify with chkdsk that the image was in fact without problems
  5. Detach the VHD file using diskpart
  6. Copy the VHD file to a HDD that Paragon HDM would recognise
  7. Use Paragon HDM to perform a V2P copy
    • Paragon expects a .VD file, but if you ask it to use all file types, it does recognise that VHD files contain disk images

17 years ago, C:\nul\nul crashed/BSOD Windows; now $MFT does for Windows < 10

History repeating itself: [Archive.is31607 – C:\nul\nul crashes/BSOD then, now it’s this:


All versions prior to Windows 10 and Windows Server 2016 seem vulnerable.

So add $MFT to this list:

The following device names have been known to render a system unstable: CON,

Oh BTW: history repeated itself this year too. With NUL

In short, Steven Sheldon created a rust package named nul which broke the complete package manager on Windows:

BTW: one of my gripes on learning new languages is that they come with a whole new idiom of their ecosystem: rust, cargo, crates, all sound like being a truck mechanic to me.
