Raid 1, mirror or mirroring is a data storage technology that allows information to be duplicated across a number of hard drives. It provides drive mirroring, a system that makes it possible to anticipate raid failures and guarantee the security of the content on the member disk. Raid 1 is made up of two disks, which enables fast reading of information. This reading can be done on both configured disks at the same time.
If a disk fails, you can still access your content on the second disk. But do you want to know how data recovery works on raid 1? Follow this guide to understand data recovery and the use of various software.
Starting recovery with EaseUS Data Recovery Wizard
EaseUS Data Recovery Wizard is a recovery software launched in 2004. It is considered the best software, suited to beginners as well as users or professionals alike. It boasts a 99.7% success rate, thanks to its powerful algorithms and continuous updates.
This software is capable of restoring several types of content, taking into account the following elements:
- lost or invisible partitions;
- formatting;
- damaged or corrupted media;
- viral attacks;
- etc.
It can be used to recover content on several devices, such as internal or external hard drives, USB drives, media players, etc. EaseUS can recover up to 2 GB of data and supports more than 1000 file formats. But what should you do if your disk fails completely? Simply select the data storage media, whether internal or external, then run a scan to search for information.
Previewing lost disk files
Your lost files may be stored among the deleted files on your disk. After the search scan, you need to preview the lost data to check all the content. The software you used will display the scan results.
The files that can be recovered are organized by format. You will therefore need to open each format and select the desired information. The filter function in the ribbon can help you quickly find files.
Specifying the location of recovered files from the raid 1 drive
Once the scan and preview are complete, you need to specify a location to save the recovered data. Keep in mind that the raid 1 system is both the best fault-tolerance system and the simplest method for creating storage on the failover disk.
However, the system costs 50% of the total storage capacity. Data must be extracted from raid 1 to free up space. As such, you should choose a data storage option from among the other raid types.
- Raid 0: this raid system combines several disks. It provides good read/write performance. However, it offers no fault tolerance for hard drive failures.
- Raid 5: it improves read/write performance without compromising the integrity of each piece of data. It distributes parity blocks across the smallest disk.
- Raid 6: it offers good read/write performance, characterized by double parity distribution.
- Raid 10: thanks to its arrays, it ensures good read/write performance, owing to the raid 1 sub-array.
Recovering data with other types of raid recovery software
The system is designed to improve data storage reliability. It is often considered a secure system. Yet, it is exposed to the same failures that cause data loss. Recovering this data from raid hard drives can vary depending on the hardware or software.
Using recovery software is a good alternative, since the data is stored on separate disks. However, hardware should not be overlooked when it comes to data recovery on a disk. Here are a few applications that can facilitate content recovery.
- DiskInternals: this is automatic software that lets you rebuild multiple arrays, such as a hard drive.
- Stellar Phoenix Windows Data Recovery: it allows remote data recovery.
- UFS Explorer RAID Recovery: you can recover data at any level and perform raid configuration.
Of course, the best method remains to contact a data recovery professional!
