my computer doesn't show some of my hard disk drives it only shows two but i partitioned it to 6 drives. it partitioned it into 6. but recently i can't find 4 of the 6 drives. canany one solve my problem.
windows explorer naturally hides empty drives by default.
You can run diskmgmt.msc and see all the drives and their partition layout. You may need to assign drive letters to them or initialize them for use as suggested.
