  RAID 0 interesting problem, DW sees it, Disk Utility doesn’t in app, but does in Terminal

  Posted by David Schneider on March 15, 2011 at 5:59 pm

  So I have a 3 drive (3x500gb) Internal RAID0 set up for speed. It is also backed up in another place.

  I have encountered an odd situation. I used diskwarrior 4.1.1 and ran it on the RAID. After running it, I was asked if i wanted to replace the current structure with the new structure. I said yes, as I was able to preview it and it looked fine.

  Now… restart… and RAID doesn’t show up on the desktop. Check Disk Utility and it is there but not as a RAID, but rather as 3 RAID slices.

  go to the command prompt and type in checkraid

  and it sees all 3 drives, tells me they are online.

  so I go back into DW and run the rebuild again. This time I only can bring up the RAID as the Preview. but when I tell it to replace… nothing appears on the desktop.

  I am afraid the 1st DW run may have caused some problems with the partition table?

  This was the 1st time I had run DW on this Striped set.

  Now I am just curious how (can I?) to get it back.

  I have heard about copying partition tables, re-initializing with the same parameters etc…

  but does anyone have any thoughts about it? since it is all backed up, I am willing to take a chance… but also quite interested in figuring this out just for my knowledge.

  THanks for any thoughts you all might have.

  I have searched for similar situations, but I usually come across a RAID0 drive failing… which is not the case for me. they are all there… i just can’t get them to come up as one drive…

  David
