Hitachi G-RAID 0 Parameters

[ddrecovery]

I have just had in a Hitachi G-RAID 0. It is 2 x 2TB. When the RAID failed the client ran checkdisk so I wanted to check if anyone knew the default RAID parameters? I have read that its a one sector (512b) stripe which seems strange. One of the drives is showing a partition starting at LBA -0 and a size of 0.00GB, so I think checkdisk did a job on it.

Both original drives crashed my system when connecting to a SATA port, so I imaged them with a DDI, but the new drives still cause it to crash. I can however see them both though USB connections.

Any ideas?

The partition start is actually -1, not -0 as detailed above.

I had few weeks ago a similar case with G-raid 2x 1TB HDDs level 0 (stripe). The block size was indeed 1 sector (512 bytes). All data recovered successfully.
Try to set block size to 512 bytes and perform a full scan with recovery software to see the result.

What software did you use. All the standard ones don't allow you to set a 512 byte stripe?

R-studio and ufs allows 1 sector, 512 bytes setting.

I have R-Studio 7 and it only goes down to 4KB stripe size (I might be missing something). I did however get the custom setting in UFS Explorer.
Many thanks for you help.

You need to type in manually, not by the drop downs.

[kyriakosxn]

yes, you can set it manually to 512 bytes

we have had good luck using reclaime for raid to determine raid parameters.
