LACie Ethernet Disk (301299u) RAID configuration

[hddnb]

Hi All Gurus,

Anybody has the experience with the hard drive RAID configuration of this 4X750 hdd unit. System crashed since a lot of bad sectors. Seems the last drive has a little data and the 1st and 2nd almost full. Any helps would be appreciated? Thanks.

try this to see if helps.

it should be XFS file system and possibly a 256k sector size, and backwards dynamic or just backwards

I already had a disk from LACie with 4 disks and it was a JBOD of two RAID0.
Maybe it will be usefull.

Thank you, Cleanroom and ici. One guy from LAcie said it is NTFS FS but he could not release the RAID configuration. ici might be right or it may be 1 RAID0 of 2 JBODs based on the data distribution. I will try both of them and see.

In R-S, the four drives looks like that in the picture. The 1st one has different partitions from others. How to create a RAID as

JBOD(RAID0(HD1+HD3) + RAID0(HD2+HD4)) or
RAID0(JBOD(HD1+HD3) + JBOD(HD2+HD4))

JBOD(RAID0(HD1+HD3) + RAID0(HD2+HD4))

Well if it's the same setup as the Lacie ethernet server (19" rack size) I have at home, then probably you're looking at a JBOD...
It actually doesn't look like a RAID0 to me, because of the differences in size allocation between drive 0 and the rest (it looks like that in my system too)...

[hddguy]

The setup is different to the 19" unit you refer to.

This is a RAID0 array combined with JBOD in 90% cases.

From your picture it does look like a jbod. One way to verify is see if you can get data from the first drive with the NTFS partition with no corruption. Look for large files. If they come off clean then it is not striped and a jbod.

hddguy,
How do you know that this setup is different? I looked up the specs of this machine, and it is actually the same as the one I have... The 3.9GB partition which is visible is a Windows XP partition (in the one I have) running a set of drives as dynamic..

Cleanroom is right.. You should be able to verify using that first partition...

offtopic.. The system is really unsafe the way Lacie sets it up

Thank you guys. From an individual drive, I can get 5MB picture files without corruption. Also I can even get some folder and file names. What I am trying to have is the whole folder structure or the secondary level folder name and file name. Xanh is right the 3.9GB is for xp partition.
