Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

I have a RAID that came in with 2 failed drives. I was able to get both drives operational, and have created full images of all drives within the array. It was a Dell RAID 5 server, and I was able to reconstruct the array and destripe it to a single drive. The problem now is that no volume or netware partitions are found. I actually installed the destriped drive into a system and it will go through the Novell boot process, but the system stops at a colon prompt. I've tried running VREPAIR, just to see if the volume can even be seen, but I get the error "no netware partitions were found". I'm really trying to avoid carving the raw data, and would like to find a way to regenerate the original file structure. I know the stripe was rebuilt fine, because image files that are fairly large (around 4mb or more) are able to open without any problems. It just seems like the volume is toast. Does anyone have any ideas as to what I might try? Thanks in advance. Feel free to PM if you wish.

Oh man Netware - what a pain in the ass. You need to tinker around with it - i cannot remember much of that- actually don't want to. Hope you find a solution

You tried Nucleus Kernel Netware?
Worked for me a few times.

Yes I've tried about every software solution there is and nothing detects a volume unfortunately.

1) May be some drives was not working for some time, you need find it and miss it.
2) Big image files, which recovered in RAW mode, couldn't 100% indicate, becouse its cut from header to header ,and real size could be much less
IMHO I think, you reconstructed this raid5 not well.
What was the order type and block-size?

There were 2 drives that had failed, and both were repaired and imaged, along with the good drive. The array itself is pretty much the standard Dell configuration, with backward-dynamic parity and a 64K stripe. I used Winhex to determine RAID parameters manually. It's only a 3 drive array, and there's no doubt it's a 64k stripe, so possible configurations are fairly limited.

Two drives die at the same time very rare . I think one of them died much earlier, and raid has working without it. When next drive has died , you have got degrated array. Now you are reconstructing it with both drives , but the first drive you need to miss.
Try this.

I understand what you are saying, but both drives died at the same time. There was a voltage surge due to a storm. One drive had just the electronics damaged, the other drive had the electronics and the preamp damaged. I was able to repair and create full images of all three drives.

Use portlock, it is a product made for netware partitions and volumes.. The other option is runtime´s Captain Nemo Pro V4.20.
