When I run the "Verify Disk"

"Invalid volume header
Invalid b-tree node size"

Short of buying a copy of DiskWarrior, does anyone have a fix for
this? Or has anyone even seen this happen before?



Sorry to hear this. What most likely happened is the partition map is
damaged. We have fixed a few of these (and picked up very happy
customers!), sometimes at no charge, sometimes for a modest fee,
depending on how much work it takes.

One of the problems with Disk Utility RAID is that it does not follow
best practices in some scenarios, and fiascos can and do happen.

Good luck, and if you are interested, let me know off list.

Thanks for the offer, Mark; I'll let you know how things go.

Unfortunately that was an unfair comment from Mark. While I respect him I suspect the comment is slightly biased. Apple's principles for their software Raid v1 was never optimal, but it's not fair to call it "not a best practice". It was a workable practice and the one they chose. The comment implies Apple did something negligent. They did not.
