10. Otkrivanje problema

This section addresses common issues you might encounter with your cenmate 4-Bay RAID Enclosure.

Q1: After connecting a new hard drive, why can't I find it or see a disc letter?

A1: 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.

P2: Tvrdi disk se prikazuje u RAW formatu u Upravljanju diskovima zbog nepravilnog izdvajanja ili nestanka struje. Šta da radim?

A2: You can attempt recovery using the chkdsk command. Open Command Prompt as an administrator and input chkdsk I: /f (replace 'I' with the actual disc letter of the RAW drive). After scanning and repair, reboot your computer.

Q3: The hard drive is dynamically invalid in Disk Management because it was previously removed from an old computer.

A3: 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.
