 Hello everybody! Watch this video to find out how to recover data from a crashed raid on Fujitsu D2516-C11 GS1 controller. A controller is the main component of a raid array because it provides the connection between the storage elements, hard disk or SSDs and coordinates the work to create a logical pool of data. When the controller breaks down, the raid array becomes inaccessible and data recovery becomes an urgent need. In today's video, we'll explore one of the most complicated situations related to raid arrays – data recovery after a controller breakdown. The raid technology is a method to combine several storage devices, various hard disks, into a single logical unit in order to improve performance, reliability of both of these characteristics at the same time, depending on the disk array level. When the controller is out of order, the raid may become inactive and the accessories data will be lost. To recover it from a crashed raid requires specialized procedures and tools capable of restoring the files back to their normal condition. In this video, we'll show you how to replace a faulty controller and recover data from the hard disk without having a healthy controller at hand, but with the help of a specialized software product. Here are a few steps to take if you want to replace a faulty Fujitsu D2516-C11 GS1 controller without losing data from the raid. First of all, you need a controller of exactly the same model for the Fujitsu D2516-C11 GS1. After that, make sure that this controller has similar characteristics and specifications, namely the corresponding firmware to ensure its compatibility and proper operation. To view the controller properties, open its BIOS. For this module, the key shortcut to use is Ctrl H. In the menu that opens, select the controller, open its properties and check the firmware version. If you don't know what version was used in the faulty controller, you should update the firmware to the latest version. However, there is still a risk of data loss, so your next step should be to back up your disks. This is important to ensure additional protection in case of an emergency. After that, disconnect the storage system from the power source and remove all cables connected to the faulty controller. Then, take the old controller carefully out from the system case and replace it with a new one. Make sure that all cables are connected properly and sit tightly in their ports. Power on the system and wait until it boots. Access the new controller's settings and recover the rate. The controller should identify the disk ray automatically and restore its variability with the data stored on it. If it doesn't happen, upload the configuration manually. To do it, open configuration wizard. Add configuration. Then manual or automatic configuration. Add. Accept. It should be noted that the process of replacing a controller and recovering the rate may vary depending on the specific controller model and your system settings. That's why it is recommended to consult the user manual or other documents provided by Fujitsu to clear for clear instructions and advice to replace the faulty controller with another model. If you can't find a similar controller or you can't replace the faulty item with a new one, the second method for data recovery is to use a specialized software tool – Hetman Rate Recovery. Hetman Rate Recovery supports all popular rate types, most file systems and various array patterns used by various rate controllers. It will rebuild the damaged rate with the available hard disks, so that you'll be able to retrieve important files. For data recovery, you need to connect all the hard disks to the motherboard of a Windows computer. The program will automatically rebuild the damaged rate with the available hard disks. It can also rebuild the rate system even if one or several disks are missing, but it depends on the array type. Rate 5 or 6 and its varieties. If your motherboard has less setup or is a power connector than necessary, use additional adapters and expansion cards. There are a few examples on this screen. Select the rate in the Drive Manager and check if the program managed to rebuild it correctly. It shows brief information about its properties. To get more detailed information, right-click on the array and open its properties. In the Array tab, you can view the hard disks included into this array. If everything is correct, right-click on the volume and choose Open. After that, select the scan type – File Scan or Full Analysis. For status, recommend running a File Scan first. It will take less time. This type of scan can find the required files in most data loss scenarios. If File Scan is not available or the program can't find the missing files, then go for Full Analysis. Go back to the main window, right-click on the volume and choose Analyze the game. Full Analysis, specify the file system, and click Next. When the scan is over, open the folder where the lost files used to be. All files can be previewed, so you can see the contents of documents, photos, and even videos. Also, the program can display previously deleted files which are marked with the right cross. Select all the items you want to recover and hit the Recovery button. Specify where to save the files, choose the Disk and Folder, and click Recover again. You will find the recovered files in the folder you have chosen. In some situations, the program may fail to rebuild the rate automatically. It can happen when the SERP's information on the disks is erased, so the program cannot identify parameters of the crashed rate. In such cases, the rate constructor with the manual build feature will help you. This tool will save the day when the disk beginning is erased, together with the information about the array parameters. This is what typically happens when disks are connected to another controller and the previous configuration is erased when the rate is rebuilt or when disks are initialized. After initialization, data will be erased completely. So if you know the array parameters, start the constructor, choose Manual Mode, and choose Next. Specify the array type, block order and size. Add the disks that you used to include and replace the missing disks with empty drives by clicking the plus button. You may have to specify the offset, which tells you where the beginning of the disk is located. When you give all the parameters you know, you will see your rate and if all information is correct, you will see its folders here. Fill in all properties and click Add. After that, the rate system will appear in the Drive Manager. Now, start the scan. Search for files and recover the ones you need. Summing up, today we have explored several ways of recovering files when a rate controller for GSU-D2516-C11GS1 is out of order. I hope this video helped you to understand how to recover data from a rate system. Remember, that recovering data from a rate can be a complicated process and it is important to follow the correct sequence of steps. For starters, we recommend replacing the folder controller. But if it's not possible, now you know which software tool can help you solve the problem. Also, don't forget about regular backup to prevent data loss in case your rate system fails or crashes. And that is all for now. I hope this video was useful. Remember to click the Like button and subscribe to our channel. Leave your comments under the video. Thank you for watching. And good luck.
