i need to mount 4 hdd from a pegasusR4

Mounting hard drives from a Pegasus R4 can involve several steps, depending on your operating system and whether you're planning to set them up for use in a RAID configuration or as standalone drives. The Pegasus R4 is a Thunderbolt RAID storage system, and its drives are typically managed through RAID configurations. Here's a general guide on how to mount the drives on both Windows and macOS. ### For macOS 1. **Connect the Pegasus R4:** - Use a Thunderbolt cable to connect the Pegasus R4 to your Mac. 2. **Ensure Proper Power:** - Make sure the Pegasus R4 is powered on. 3. **Open Disk Utility:** - Go to `Applications > Utilities > Disk Utility`. 4. **Locate the Pegasus R4:** - In Disk Utility, you should see the Pegasus R4 listed as an external device. If it’s configured in a RAID setup, you may see it as a single logical volume. 5. **Mount Drives:** - If the drives are not automatically mounted, you can select them in Disk Utility and click on the "Mount" button. - If they are part of a RAID, just accessing the RAID volume through Finder should mount it automatically. 6. **Format (If Necessary):** - If you need to format the drives, select each drive in Disk Utility, click on "Erase," and choose the file system (usually APFS or Mac OS Extended for macOS). ### For Windows 1. **Connect the Pegasus R4:** - Connect the Pegasus R4 to your Windows PC using a Thunderbolt cable. 2. **Install Drivers:** - Make sure you have the necessary drivers installed for Thunderbolt connectivity. These can usually be found on the manufacturer's website. 3. **Open Disk Management:** - Right-click on the Start button and select `Disk Management`. 4. **Locate the Pegasus R4:** - You should see the Pegasus R4 listed in Disk Management. If it's a RAID configuration, it may appear as a single volume. 5. **Initialize & Format (If Necessary):** - If the drives are unallocated or uninitialized, right-click on them and select `Initialize Disk` to set them up as a RAID or standalone drives. - If required, create a new volume by right-clicking on the unallocated space and selecting `New Simple Volume`. 6. **Drive Letter Assignment (If Needed):** - Ensure that the mounted drives have assigned drive letters for easy access. ### Important Notes - **Backup Data:** Before formatting or changing RAID configurations, ensure all important data is backed up. - **RAID Configuration:** If you're setting up RAID, remember that RAID levels (like RAID 0, RAID 1, RAID 5, RAID 10) will impact performance and redundancy. Choose one that suits your needs. - **Manufacturer Software:** Many times, manufacturers provide dedicated software for managing RAID devices. Check if Promise Technology (the maker of Pegasus R4) provides any utility that can simplify this process.
