hi all
i am currently workng on this setup which is 1tb with 2 x 500gb drives which apear to be in a striped setup. I believe that WD uses the linux file system for these drives.
issue is 1 drive works well, the other drive has bad blocks, i have imaged both drives to new drives so at least i have 2 stable drives to work with.
i thoght these may be striped so i used raid reconstructor to build 1 image and then tried extracting the data from this image, however i am getting alot of corrouptions in the pictures, alot of the photos are also opening up as very small photos and cant be expanded, as if they are remaining as previews, the file sizes on these photos seem to be 4 or 8k on all of them.
i am thinking i may need to use a program that will let me specifically deal with linux partitins, but my first question is, is there a more appropiate tool to use to try and merge both discs back into 1 image as i am suspecting that raid reconstructor may not work as this may not be nescessarily a striped set.
thx for having a look

About this, search post from jono-ats. I think it's about a week or two before.

thx anyway

You are half way, don't hurry. Try to point out the exact filesystem structure and stripe block size. Try to image the drives to two same WD and use the same box. If you had no problems in imaging, this should work - unless the array is corrupted.

hello crecomp.
which block size u r trying to reconstruct it on?

The WD 1 TB drive I worked on used sector mapping - not any kind of regular stripe size. RAID Reconstructor won't work on these.
If your RAID controller / interface PCB has died, find another one. If not, use the original to reconstruct the RAID.

Black St, it appears the array is corroupted, i imaged the drives installed them into the array, external wd casing booted up normally, i was able to log on to management console through web interface, in there i cant see any shares at all, so i strongly suspect when damage to 1 drive happened i lost my entire disk .
Jono ats, i plugged in the imaged drives into the casing, the casing along with board seem to be ok, when you are saying use original to reconstruct the array can you please clarify as i am a bit confused.
as there are 2 drives and 1 was faulty the original setup offered no redundancy so i cant use the existing drives to reconstruct the raid.
should i be trying to power the drives from the enclosure and somehow make an image of both instaled drives, using the original controller card that the data was written with, if so what software have you used for that, ?
if you feel more comfortable you can PM me
i used Rstudio linux recovey and have got better results whereby at least the images that are being recovered are expanding to full size, however i am getting some pictures full of lines and some just with small lines through them
thx for the replies and looking guys
