HDD GURU FORUMS

Anyone know the strip size and offset for this drive - or any other helpful info?

I've run the usual RAID tools, etc. and get a perfect directory, but all large files are corrupted, JPEGs have horizontal stripes, etc.

I think I'm just missing a parameter.

Have you tried two new drives back in the enclosure and create a new raid 0 with the WD utility? It might tell you the stripe size or if the unit corrupted the data.

Do you know if its RAID0 or JBOD?

Cant be too many possibilities, maybe array has a reserved area? You can use the Xor Test in Raid Reconstructor to tell you where the Boot sector/partition start is, from this you can tell which disk is first, and also if there is a header involved?

Also if it is a network-based device it is going to have a separate system partition for the linux-ish OS that it runs.

That was something I was thinking to do. I was just hoping to find a quicker solution if available.

Thanks for your help.

True, but this isn't a NAS drive. It's 1394/USB.

Thanks

Good ideas. This is a RAID0 for sure.

Thanks for your help.

did you figure out the parameters? i'm working on similar. wd 10000 d033 drive, 1tb raid0.

Not yet. I initially thought I had success with a 128/64 setting (I tested it briefly and WD Book showed up). But when I imaged the drive all of the way, it was wrong.

I'm awaiting to hear from WD's "24 hour tech support." That was a few days ago . . . .

if you hear back let me know! please.

turns out the wd10000 mybook world edition drive i am working on is jbod, not raid0...

Any luck with your RAID yet?

if you're still waiting for wd to get back and you KNOW it's raid0, i'd recommend just downloading raid reconstructor like hddguy recommends and running the analysis which should/might tell you which drive is first and what is the right block size. it's free and takes about 5 minutes to get going and might save you a lot of time.

before you get that work correctly, need to determine if your drives are set-up using entire disks as raid or one partition each and if so need the start sector of the raid partition.

U13,

Thanks for the suggestion.

We own a bona-fide copy of RAID Reconstructor. I never could get anything conclusive from it. Depending upon the analysis settings, it would suggest very different configurations. I could never get the "green light" entropy blessing.

I tried to image using different stripe parameters and never got uncorrupted data.

I tried a few other tools, also without success.

I just heard back from WDC. They said that the drive was sector mapped, and that it did not use a standard striping configuration. No wonder . . .

Anyway, that was the info I was looking for, and I am working on a strategy which I hope will prove successful. Both drives had read errors, but the enclosure seems to work just fine. That bit of info should make the strategy rather obvious . . .

Great. Sorry, wasn't trying to be obvious. Good luck.

Thats just typical of WD!!

Good luck, let usk now if you get this one

I got it. I'm copying the recovered data now.

Thanks for all of your suggestions.

question for the future...

what model was it, and how to identify that kind of non-standard striping? any thoughts?

FYI, this was a My Book model WD10000C033-001.

There is another number on the label: 3707A

S/N: WUT211065276.

I can't tell anything about mapping from looking at the PCB.

Jono

Has anyone sucessfully been ableto recover data from a My Book World Edition II with Dual 500GB drives in a RAID 0 configureation. This thread did say the data was copying from his config but How exactly was it done.
