I was trying to migrate a Win7 OS from a HDD to a SSD.
I've created 2 partition with 1024KB offset, with diskpart: 100MB System Reserved and a 60GB for C:.
I've cloned their contents using Easeus Disk Copy.
I've loaded the Windows 7 Boot DVD, and wanted to use diskpart to drop the letter for the System Reserved partition and make it hidden.
select volume 0 detail volume attribute volume set nodefaultdriveletter attribute volume set hidden
These 2 attribute set commands actioned on both volumes (0 and 1, MSR and C:) instead of the selected one, and viceversa.
I've tried to clear these attributes from volume 1, but it cleared them also from volume 0.
Why does DiskPart have this behaviour?
