I have a Lenovo laptop with SanDisk 512 Gb SSD that came with preinstalled Windows 10 Pro. The disk P/N as shown by both the Lenovo utility and Device Manager corresponds to the 512 Gb model. The Lenovo utility and diskpart show the disk as having 512 Gb capacity (well, actually 476 Gb formatted space).
However, Disk Management shows the disk is only 256 Gb in size, and diskpart shows there are 4 partitions (including C: of 237 Gb and 3 more system/recovery partitions - 1 Gb of total size) and no more free space.
chkdsk finds no errors. No suspicious events both in the Application and System logs. All drivers are up to date. BitLocker is enabled.
Where is half of the disk capacity?
