6. Конфигурација на RAID
The cenmate 704RU enclosure supports various RAID modes. Changing RAID modes will erase all data on the drives. Always back up your data before making any changes.
6.1 Understanding RAID Modes
| Режим RAID | Minimum Drives | Опис |
|---|---|---|
| Нормално | 1 | Each drive operates independently. |
| RAID 0 | 2 | Striping. Data is split across multiple drives for increased performance. No redundancy. |
| RAID 1 | 2 | Mirroring. Data is duplicated across two drives for redundancy. Capacity is limited to the smallest drive. |
| RAID 3 | 3 | Striping with dedicated parity. Similar to RAID 0 but with one drive reserved for parity data. |
| RAID 5 | 3 | Striping with distributed parity. Data and parity information are distributed across all drives. Offers good performance and redundancy. |
| RAID 10 | 4 | Nested RAID (RAID 1+0). Combines mirroring and striping for high performance and redundancy. Requires four drives. |
| Клон | 2 | Создава точна копија од еден диск на друг. |
| Големи | 2 | Concatenation (JBOD-like). Drives are combined sequentially to form one large volume. No redundancy. |

6.2 Setting RAID Levels
The RAID mode is set using DIP switches located on the back of the enclosure. Refer to the diagram below for specific switch configurations.
- Исклучете го the enclosure and disconnect it from the computer.
- Set the DIP switches to the desired RAID configuration according to the diagram.
- Притиснете и задржете го Ресетирање копче за 5 секунди.
- Reconnect the power and turn on the enclosure. The new RAID mode will be applied.

Figure 4: DIP switch configurations for RAID levels.
7. Initializing and Formatting Drives
After installing new drives and configuring RAID, the drives must be initialized and formatted before use. This process is typically done through your operating system's Disk Management utility.
- Поврзете го куќиштето со компјутерот и вклучете го.
- Open Disk Management: Right-click 'This PC' (or 'My Computer'), select 'Manage', then 'Disk Management'.
- Locate the new disk(s) (they may appear as 'Unknown' or 'Not Initialized').
- Right-click the disk and select 'Initialize Disk'. Choose MBR for disks 2TB or less, or GPT for disks larger than 2TB.
- After initialization, right-click the unallocated space and select 'New Simple Volume' to create and format a partition. Follow the wizard to assign a drive letter and format with your preferred file system (e.g., NTFS for Windows).
8. Операција
8.1 Пренос на податоци
The enclosure supports USB 3.0 (5Gbps) and eSATA for high-speed data transfer. Connect the appropriate cable to your computer for optimal performance.

10 Смена на проблеми
This section addresses common issues you might encounter with your cenmate 4-Bay RAID Enclosure.
П1: Откако ќе поврзам нов хард диск, зошто не можам да го најдам или да ја видам буквата на дискот?
А1: New hard drives must be initialized and formatted before the system can recognize and use them. Refer to Section 7 for detailed steps on initializing and formatting drives in Disk Management.

Figure 10: Troubleshooting steps for drive recognition and RAW format.
П2: Хард дискот се појавува во RAW формат во Управувањето со дискови поради неправилно извлекување или прекин на електричната енергија. Што треба да направам?
А2: You can attempt recovery using the chkdsk команда. Отворете ја командната линија како администратор и внесете chkdsk I: /f (replace 'I' with the actual disc letter of the RAW drive). After scanning and repair, reboot your computer.
П3: Хард дискот е динамички неважечки во Управувањето со дискови бидејќи претходно бил отстранет од стар компјутер.
А3: This is a system-related issue. Reinstall the hard drive into its original computer motherboard, back up the data, and then convert it to a basic disk. If the old computer is unavailable, you may need dynamic disk conversion software.

Figure 11: Troubleshooting steps for dynamic invalid drives, missing disc letters, and disconnections.
Q4: Hard drive shows up but has no disc letter?
А4: In Disk Management, right-click on the Disk Partition section and select 'Change Drive Letter and Paths...' to add a drive letter for use.
Q5: The enclosure automatically disconnects during transmission and then reconnects itself after a while?
А5: This could indicate issues with the USB interface on your computer, the USB cable, computer USB drivers, the hard drive itself, or the hard drive enclosure. Systematically check each component. If the problem persists, contact technical support.
