I have HP array with 12 disk each on 2 TB. I configured them with RAID5 Suddenly two disk has ben failed and after two days another disk have been failed. And the array failed to start. I replaced the two failed disks. The array configuration utility show me option to "re-enable the array"... My question is if I choose that option, will I recover my data? Or is it lost?

RAID5 only provides one disk fault tolerance. Replacing two disks of a RAID5 array effectively means losing all stored data.

So, short of contacting professional recovery services, your data are gone.

More broadly speaking, never use RAID5 for wide arrays and/or large HDDs.

    That depends on the damage and can only be answer by said recovery services. Note that RAID increases uptime but doesn't replace a reliable backup. – Zac67 Mar 27 '23 at 17:10
