How to recover data from raid 1 on mac os?

Question

macOS

Good afternoon! I had a raid1 on a smart array 212. At one point, he began to write that everything was broken, the data was lost. Pulled out the disks and plugged usb to mac os. through r-studio demo I found the data I need, but I can’t restore it because of the demo version. Are there any analogues / methods of recovery in this case? The problem is that there is no Windows. There are macos and centos.

Answer 1

Ride1 is a mirror, why restore from it ...? Probably one disk has failed, crush it with a donor.

Answer 2

To work under both Mac and Linux, you can use UFS Explorer , it has the appropriate versions. Any edition is suitable, except for Raise Data Recovery, where work with RAID arrays is implemented through the RAID Access Plugin - RAID Builder. But if you work with only one disk, then it will do.
However, these programs require the purchase of a license, and only small files can be recovered for free.
If you need a free option, then try the following: under Linux, make an image of the disk from which you want to recover data using dd. If necessary, you can also try to make an image of the failed disk using gddrescue(GNU ddrescue).
Then open the image withthe old version of the free R.saver , it supports working with images, but is only available for Windows. You can try to run the latter either in a virtual machine, or by making a bootable USB flash drive with one of the admin or emergency distributions.
R.tester doesn't require installation, so it should run fine.
