How to recover a Dynamic Invalid Disk in Windows 7 / 8 / 10
A tutorial on how to bring back online a invialid disk which may have occured after updating a service pack. (SAME STEPS FOR WINDOWS 8)
IF YOU HAVE PARTITIONS:
for each separate partition you will have to change 42 to 07 for all instances. For example I had 4 partitions and I had to change 1C0,1D0,1E0,1F0 all to 07 from 42 to get them all to show up in explorer.
IF LINE 1C0 DOESN’T WORK:
For those of you who have tried this fix and changed 1C0 from “42” to “07” and its still invalid…. Check line 1D0 and see it it is a “42” as well.. If so, change this to an “07” as well.
If any of those don’t work then try changing all 42’s to 07.
NOTE: DATA MAY OR MAY NOT BE LOST AFTER THIS PROCEDURE. I AM IN NO WAY RESPONSIBLE FOR WHAT HAPPENS TO YOUR DISK. YOU DO THIS AT YOUR OWN RISK. THIS VIDEO IS FOR EDUCATIONAL PURPOSES ONLY.
