4. Иштөө нускамалары

After physical installation, the Lexar NM790 SSD requires initialization and formatting before it can be used for storage.

4.1 Initialization and Formatting

• Windows үчүн:
  1. Right-click on the Start button and select 'Disk Management'.
  2. Locate the newly installed SSD, which will likely appear as 'Unallocated' space.
  3. Right-click on the disk and select 'Initialize Disk'. Choose GPT (GUID Partition Table) as the partition style.
  4. Right-click on the 'Unallocated' space again and select 'New Simple Volume'. Follow the wizard to assign a drive letter and format the drive (NTFS file system recommended).
• macOS үчүн:
  1. Тиркемелер > Утилиталардан "Дисктин утилитасын" ачыңыз.
  2. Select the newly installed SSD from the sidebar.
  3. Click the 'Erase' button. Choose a name, format (APFS recommended), and scheme (GUID Partition Map). Click 'Erase' to confirm.
