HFS+ file system RAID 0 recovery

October 19th, 2010, 12:40

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:

Thanks.

Try JBOD is common in MAC Raid 0

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

This printscreen sample not original :)
If this Raid from that Lacie Extreme (i think about) , so it's really has 1 sector block-size. :)

Don't worry, at least when someone here forgets to convert from hex to dec it doesn't burn up a US$125M spacecraft in the Martian atmosphere :mrgreen:
