Hey and thanks for a greate product.
I am working on a Lacie Bigger Disk, it has 4 250 GB drives and is supposed to be a raid 0.
When i open all the drives in x-way forensic it shows me an access button for a HFS+ filesystem. In total 4 partitions, one of 931 gb HFS+.
If i open this partition it shows me the directory, but i get some error messages:

Possibly unable to fully determine the location of the file or directory "D" on the volume.
Possibly unable to fully determine the location of the file or directory "f" on the volume.
Possibly unable to fully determine the location of the file or directory "S" on the volume.
Possibly unable to fully determine the location of the file or directory "S" on the volume.
Possibly unable to fully determine the location of the file or directory "S" on the volume.

The list wery long :-) If i try to access the files i get another message:

Cannot read from Sector 1 197 315 337 of ST3250823A. Incorrect function.
Cannot read from Sector 1 197 315 338 of ST3250823A. Incorrect function.
Cannot read from Sector 1 197 315 339 of ST3250823A. Incorrect function.
Cannot read from Sector 1 197 315 340 of ST3250823A. Incorrect function.
Cannot read from Sector 1 197 315 341 of ST3250823A. Incorrect function.

Cannot read from Sector 1 197 315 343 of ST3250823A. Incorrect function.

This list is also wery long ....


Does anyone have an idea? Is this a hdd problem og a filesystem problem?

If you open the 4 component hard disks individually as you say and then open a partition from within one of the hard disks, then of course 3/4 of the striped data is missing and that leads to errors such as the attempt to read sectors that don't exist.

Either you would have to open the simulated 1 TB hard disk or you would have to reconstruct the RAID 0 with the help of the 4 component hard disks yourself (Specialist | Reconstruct RAID System in the main menu).

Ok, thanks for the fast reply. Do you have any idea on how this type of raid is configured?

Which model is your disk ?

There should be a six digit part number starting with 3.....

Problem is that the 4 drives are not configured as true RAID 0 and you will not be able to rebuild with WinHex. Where are you based as you will probably need to look to a data recovery specialist.

The older boxes are mostly likely concatenated/spanned. I've seen some of the newer four drive LaCie's come as two drives (the primary and secondary on same channel) 128 kb stripe and then the two stripe sets (one on each channel) spanned together. Fun rebuilding those.
