[sdiy] OT: how to save a dead Raided Drive?

at this point it looks like sourcing an exact replica of my LACIE drive is going to be impossible

it is the model number lacie 300794u  (500 gig extreme) and it is from around 2006 or 2007.

no one has it for sale (well one person for 285

SO i think i will get 2 external IDE to USB enclosures, hook em up to my MAC and try to get the RAID decoded with 
software? or i have a sometimes working Vista machine...

once i buy the enclosures I will report back

Thanks To everyone for the help

>> Dear Dan
>>
>> I might be able to help with this.
>>
>> Sad to report, the Lacie external drives don't have a very good reputation

>> very good, photo quality, colour graded monitors, and so the photographers
>> also used to go for their hard drives as well. I've had to fix 3 or 4. In

>> another supply to see if the drives boot up. It must be exactly the same
>> voltage rating, and the same or higher current rating. You could test the
>> original supply with a dummy load, and your test meter. Might be worth

>>
>> I never did find out the drives configuration: if it's a stripe, and one

>> 50 - 50 between the two drives. If they are set up as 'JBOD', (Just a

>> of Discs), then some stuff may be recoverable. If it's the PSU, then you
>> should get it all back.
>>
>> If it's not the power supply, then I'd email Lacie and ask if they do
>> recovery, they will at least know exactly what the disc format is.
>>
>> Sadly I'm in the UK, if you were here I'd get you to send the drive box

>> and take a look.
>>
>> If you really want to go it alone, first of all, find out the name of the
>> chipset in use. There are only a few IDE/USB sets out there and that would
>> let me know what to look for - it's quite probable that another external
>> drive case uses the same set, and for a reasonable cost you could check if
>> it was a drive or the interface that had failed. If it's the drives, you
>> coudl 're-engine' the box with another couple of drives.
>>
>> Hope this helps
