It was caused by a few things. Remember I've seen a lot of PCs over the years so here goes. First it happens with dated BIOS and OSes. Next I've seen it when the owner used other than the OS to partition and a limit was hit. Or tried FAT32 instead of NTFS.
Hello, I have a 3tb hdd and for some reason after a new restore, it created a 746.5 gb secondary partition with the same name "Drive 0 Unallocated Space". Both my main hdd and this one have the same name, and I can't delete either of them. Can someone help me with this?
