I have two drives: a 128 GB SSD and a 1 TB HDD. I very recently installed Windows 10 on the machine and it's (obviously) installed on the SSD.
At the moment, the SSD consists of two partitions:
- 118 GB NTFS (Boot, Page File, Crash Dump, Primary Partition)
- <1 GB (Recovery Partition)
The problem, however, is with the HDD. It consists of two partitions:
- 10 GB NTFS "DriverCD" (the machine was bought without the system installed, so this partition contains drivers and documentation)
- 921 GB FAT32 (System, Active, Page File) - let's call it (D:).
I would like to format the (D:) partition to NTFS to not be limited to 4 GB files (a FAT32 limitation). The Disk Manager does not allow me to do it since it treats this partition as System for whatever reason. The partition contains these hidden files: D: dir
Note: before the Windows 10 installation, the (D:) partition contained a FREEDOS installation that I removed (cut and backed up, actually) using Windows Explorer after the Windows installation. Could that have anything to do with this?
I have tried making the (D:) partition INACTIVE in DISKPART in the command prompt, which resulted in breaking the booting process (I reverted the change by making it ACTIVE again in recovery mode).
What should I do to unmark the partition as System, format it, and use it as a simple data partition?
