Ok, here's my dillema:

I currently have two WD2500JB's hooked into PATA/SATA converters, and then linked onto my Promise Fastrack 396(I think) onboard SATA RAID. Well, I recently booted up, and it said my raid had bombed. I looked in the fastbuild utility, and the drive is present, but not a part of the array. Is there to reinsert the drive back into the array? All my important data is backed up to CD, but I have a bunch of ripped CDs and DVDs that I don't wanna have to re-rip. Is there any way to build it back?

RAID 0 is notoriously unreliable and very hard to recover data from when it breaks.

Please read my Knoppix posts here:

I've used Knoppix to recover data before however you have to get very lucky to recover data from a broken RAID 0 array.

Well, I know WHAT to use to salvage data, I just don't know HOW to do it.
I believe the procedure involves destroying the current array, re-creating an identicle array without initializing (quickformat) it. From there I don't really know how to get back at the data. This has actually happend to me before (which is why i backed up my important stuff), and when i tried that, i was able to get chkdsk to reconize that there is data on there that needs to be salvaged...I just don't know how to get it to PUT on there.

Go into your SATA controller's BIOS and see if there is a "rebuild" or maintenance option.

This varies but deleting and re-creating the array in some cases will permanently destroy the data.

If one of the drives has crashed then there is no way to recover anything.

Double check all the connections to make sure everything is securely plugged in and both drives have power etc.

None of the drives have crashed. it's raid 0, not 0+1, so there is no availability for reconstruction in the tool. The drive is definately working, as I've said before this isn't new (it has to do with the PATA/SATA converters and so forth). I've destroyd and recreated the array before with varying degrees of success. I was just hoping someone knew a beter way, because i've never had complete success, and most of the time it results in total data loss.

Please post your full system specs.

CPU, mobo, RAM, PSU, HDDs, etc

Do you actually have a Promise 378?

What kind of adapters are you using?

Reply to linux_0

Athlon 2800+
MSI K7N2 Delta-ILSR (that's the FastTrak 376)
1gb of mixed DDR400/DDR333 ram Running dual channel
2x WD2500JB running on highpoint SATA/PATA converters
1x WD800JB (hosting OS)
Artec 16x DVD Rom
WinXP
Generic 2-fan 550w PSU

The problem is that sometimes, if the system loses power during the start-up while it's scanning drives (which happend this time...damn dog) the highpoints reset and the drive-ID gets reset, so it'll think that the device is a new drive, instead of the one that should be a part of the array.

Does your system usually lose power when the drives are spinning up?

If that is the case you need a new quality PSU.

The Promise controller on your board has 2 SATA + 1 PATA connectors, if only it had 2 PATA connectors you would be all set!

I don't know if this does any good but you can run 1 drive using PATA + 1 drive using SATA.

No, I never have problems. The only time I have power problems is when my darn dog sleeps under my desk and flops down on my power strip.

I've actually tried linking it into the PATA, too. No avail. Guess I'm stuck.

Well, I just got off the phone with the Senior Sys Admin from where I work (I'm a level 2), And he confirmed that I'm pretty much just screwed. He said my only hope was rebuilding the array exactly how I had it, then TRYING to restore the files with some 3rd party data recovery application. So, any ideas on a good bit-restoration program?

Knoppix is the answer!

http://www.kernel.org/pub/dist/kno [...] -23-EN.iso

It is a Live Linux CD and DVD and can read windows filesystems and copy the data to another HDD, USB flash drive, CD-R, DVD-R, or other storage device (including network storage over NFS, SMB/Samba/windows file sharing, etc)

PM or IM me for details.
