Raid 5 - 3 disks Maxtor - Mylex AcceleRAID 170 1ch, U160, 32

[neuron]

Hi,

The board (Mylex) don't work and we would like to recover the data in another computer.

Manual -> http://www.lsi.com/obsolete/acceleraid_ ... &locale=EN . Only the block size. And install, setup the Raid.


The block (strip) size is 64 KB=128 sectors (saw several blocks of texts).

3 disks - MAXTOR ATLAS10K4_36SCA.

But I can't get the order - backward or forward.

And MBR don't have the partition info. The partition - all 000

I searched the NTFS (512 position 3). But only find in middle of disks - 1 partition.


Thank you very much for your info,

Ruy Benton

Where are you based Ruy?

If the data is important on this array, seriously consider sending it to a company that knows what they are doing... Trying to fix the problem your self may make the problem worse - no offence, but you need to be very careful with critical data.

I agree. Raid 5 is not for beginners.

Hi,

From another forum:
"Mylex 160 and 170 are Forward Parity Rotation and the Metadata is on the back, so offset is zero - parity starts on sector 0 of the first drive and MBR on sector 0 of the second member. 64kb is the default, but can be anything from 8kb to 1024kb."

P 1 2
3 P 4
5 6 P
and so on ...

In Portugal - Europe

I don't get the idea ... I'm working with copies (R-Studio and Winhex). What will get worse?

Maybe I don't see the light at end of the tunnel ... but that's the only thing ... or I'm missing something?


Raid 5 - any software out there ?

Since MBR is unavailable and I think NTFS is the same, please can you tell the procedure to analyze the MFT and search FILE0 and INDX data back (software, programs).


A suggestion: " ... FILE records are spread across the RAID component disks, you can deduce these parameters"
