WD 1TB My Book RAID 0 settings?

[jono-ats]

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.

[hddguy]

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.

[jono-ats]

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?

[us13]

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.

[hddguy]

Thats just typical of WD!!

Good luck, let usk now if you get this one

[jono-ats]

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

Thanks for all of your suggestions.

[us13]

question for the future...

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

[jono-ats]

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.

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.
