Hi Gurus,

I have 2 hdds here and I was told it was configured as RAID0 and used with Mac. Need to figure out the parameters, like disk order, block size, and offset. I am not familiar with the HFS header strcture. Any help would be highly appreciated. The following is the HFS header dump:

Looks like your stripe size is 1 sector and the drive with the HFS header is the first drive.

If this Raid from that Lacie Extreme (i think about) , so it's really has 1 sector block-size. :)
