recently we have got a lot of these in for recovery, in most cases the external housing was damaged and could rebuild quite easily with donor external units we have, but I have rarely been able to rebuild and recover outside the unit. I am unsure what type of RAID it is, though I know it must be striped, but it is proving to be quite hard!

It seems that it is not a standard RAID0, but is not JBOD either because the data is striped. There is no parity, should be fairly easy to recover right?

Anyone have much success with these outside the unit?

Thanks

Works almost allways with winhex or ufs-explorer.
Most difficult is stripe-size and start-sector.

How is the best way to determine start sector on this raid? I usually use XOR test, even though it is not RAID5, i can still usually see where the array starts from. On the ones I have recovered outside the unit, the stripe size has generally been 64KB or 128KB. On the older 2 disk Lacies configured as RAID0 I had some with some uncommon stripe sizes, some as low as 32KB some higer than 512KB.

Its always a puzzle; observation and thinking is required.
Lacie even changes settings/controllers between different production dates of the same model.

Yea, I noticed that! Good job we are no strangers to a challenge lol

Why not just use a working caddy!

A lot of people miss me and often. Hows your LaCie problem going

Its not a problem really, we have recovered the data using the original caddy but the disks powered externally. I just wanted to know how to rebuild this manually outside the caddy just out of interest. Its not always I will be fortunate enough to be able to use the caddy.

You got any suggestions???

Nothing a good hex editor and Winhex/UFS Explorer wont fix.

Why a good hex editor AND winhex? What do you think winhex is? The problem with this forum is the volume of blatant uneducated people here

And I suppose you are the guru of all gurus??

OK smart ass. A good hex editor and UFS explorer or Winhex.

and a little knowledge and skill, which I think may be severely lacking where you are concerned

I am a spaz. whats your excuse?

Now were getting somewhere. Admitting something is the first step in recovery

You will not be able to rebuild these directly in Winhex.

I can rebuild outside the box and have done several times. The first time took me about an hour to work out what was going on.

If you still cant work it out, if what you are doing works, then carry on as you have been..

An ANALOGY:

If two of the drives are buckets of water and the other two are buckets of piss. You put your hands in the buckets of water and your feet in the buckets of piss. Where is your arse pointing ?

can't you have one pissy hand and one pissy foot? even it out.

I just finished a rebuild of a LaCie 2x250gb drive in winhex with no problems.
