Dear Experts!

I had "Dynamic Smart Array B120i Raid" in my HP Proliant ML310e Gen8 v2 Server System with 4 HDDs

= Suddenly noticed, the restarted and as I checked, showed that my one (slot 1) hard disk has failed and all data lost.

Question:

If I'll replace the HD with a new one, how I'll recover the data/system?

I am afraid because I am not an expert and don't want any data loss.

plzzzzzzzzzz help me.

Is this a RAID1 array? Typically you replace the bad drive, power on the computer and boot into the RAID controller's configuration utility. Once in the config software, you can add the new drive to your array and then select "rebuild". Data will be copied from the good drive to the new one during the rebuild process.

If it's some other type of hybrid array, it should work in a similar way. Look up the manual for your controller card.

There's no fault tolerance in RAID 0, so you would have to restore your data from a backup.

My System


As stated, in RAID 0, Striped set, if one HDD fails, then all data is lost. Hopefully you also have a backup?
In the future, if you are using RAID to get at least 3 drives and do a RAID 5. If one drive fails, you replace it and rebuild the array and there is no loss of data. However, this is still not a replacement for having a current backup.

If there's no backup available, another solution exists - bring both disks to a reputable data recovery service. They probably could help, but that will cost. And do not try to tamper yourself with the failed disk using some "hard drive repair" software , you'll surely make the situation worse.
