The hard disk drive is partitioned into two partitions by design. The hard disk drive partitions are listed as ACER (C:) and ACERDATA (D:). The ACER (C:) partition is the primary partition, where the Operating System is located. The ACERDATA (D:) partition can be used as additional storage.
Note:: The ACER (C:) partition is selected by default when new programs are installed.
- Open by pressing the Windows key + X at the same time.
- Select Disk Management.
- Right-click the Data (D:) partition, then select Delete Volume. Data (D:) will now show as Unallocated.
- Right-click Acer (C:), then select Extend Volume....
- Click Next.
- Verify you have the unallocated space selected, then click Next.
- Click Finish. After a few minutes the two partitions will be merged into a single drive.
