I have 4 hard drives that all run at the same speed, inside an internal dock.
I wanted to combine these hard drives into one drive.
Iv tried to converting basic to dynamic as well as just trying to combine hard drives using the Disk management as well as the command prompt
and no matter what I do I keep getting the message This operation is not supported by the object
Im running windows 11, all my drivers are upto date and the drives are wiped ready to be formatted.
Does it give you any additional message besides that generic one?
What specifically is the internal dock you’re using? It’s not USB3 is it?
You could try diskpart from a command prompt or try using partitionwizard which should do this. I’ve used that tool many times in similar situations. They show you both the GUI and cmd prompt method as well as with their tool at the following URL which might be worth checking out Two Ways to Convert Basic Disk to Dynamic Disk without Data Loss.
If by chance these are USB drives I’d think twice about combining them this way. I’d use mergerfs on linux or Stablebit DrivePool on windows. This way the drives are independent and fully usable as is but you get an overlay file system combining all of them. This way if a drive disconnects or is removed that slice of data disappears but the other drives are fine.
You can combine this with SnapRaid (not raid but parity) and more like a slowly created snapshot.
