    Just wanted to let everyone knows how did I recover my data from a Raid0 disaster.
    Situation: I reimaged the wrong partition with a windows xp install. That partition was the first disk of my Raid0.
    Steps to rectify:
    1. Create an image of each of the two raid partitions (2 Seagates partioned each one as 500MB and connected via sata to a Adaptec raid controller()
    2.Under Linux, run photorec on each partition to get back as much data as possible, also used extundelete.
    3.Recreated the raid, but did not format. Run again photorec and extundelete on the raid partition
    4.Formatted and restored the healthy partition from the image.

    Cheers

    Why would anybody use RAID 0 now ? That's a recipe for disaster.

    Why wouldn't you :D

    SPEED. I'm running RAID 0, but:

    1. I'm using SAS drives, which are much more reliable than SATA drives
    2. I'm using an automated backup system (Windows Home Server), which lets me restore to the previous days backup in about 20 minutes - it's like a complete image.

    What about data SAFETY ? For me data safety is much more important than speed.

    I already answered that question. My data on a SAS drive is much more safe than on any consumer-grade SATA drive... RAID 0 or not.

    And how many people can say that have their data backed up on a daily basis? I can!

    Arie & Pete, we are talking here about ordinary people having little or no deep knowledge of pros & cons of different situations. Suggesting RAID 0 to them is very bad practice as once its setup, nobody would be bothering about backups & when either of the disks gives up the ghost everything goes up in dust. It doesn't matter if you are using SATA or SAS or even solid state drives. Once the drive is dead, your data goes with it.

    We are not talking about ordinary people, because they have no idea what RAID 0 is or what it does...

    You said
    Well, experianced users also fall under the definition of anybody...

    rsinfo - why would you say noody would bother backing up? I think that anyone the looks into Raid0 would always backup;)

    Then there's the part about apps like Acronis can image a Raid0 to one drive...And then from one drive back to two.

    Human nature for one.

    When you utter the words RAID, people assume that their data is safe & even if one of the hard disk crashes they would get their data back. Had happened with one of my clients but he was using RAID 5 & could get his data back.
