Hello,

I was wondering if anyone on forum has experience with data recovery from an HFS+ drive.

I purchased Diskwarrior, and was not able to recover the drive. The data is important, but not $600+ important to me right now. I have recording studio audio files I would like to recover and negative scans from a lot of photographs. I still have the negs, so I can re-scan, but it was a lot of hours scanning and cleaning up the files.

This was my backup drive that I copied important files to.. . when my main computer drive blew up, I thought I had this backup. The studio has not had any work in over a year while I'm under construction so I this isn't mission-critical stuff with paying clients, just personal projects.

chung, at my work, i've had the pleasure of telling people that their drive is seriously damaged and that I'm going to have to send thier drive to OnTrack......it's well over $1500+ to recover data.

SpinRite recognizes Macintosh HFS partitions, ext2, ext3, NTFS, fat32, etc.....

only thing is that it runs in pure DOS, so obviously it won't work on a mac.

i just hope the drive is IDE and not SCSI

Chung,

I had an NTFS HD fail on me. To recover the data I used KNOPPIX (it's free) and has some great low level tools that can read a damaged disk.

http://www.knopper.net/knoppix/index-en.html

Also there is Tom's boot disk which has similar tools at: http://www.toms.net/rb/.

If you are interested I can look up some of my notes when I get home and foward them on to you.

I know someone at work that has some really sophisticated forensic software. He can recover ANY data with it.

If you want to go that route, just send me a PM.

I've had great luck with DiskWarrior in the past. What does it tell you about the drive?

When diskwarrior was trying to rebuild the directories or something it said, "progress slowed by hardware problem" or something like that, and I let it try for a couple hours without progress and had to force quit diskwarrior. . .

The drive was connected and disconnected only when the machine was powered off.

So, diskwarrior can't complete the scan. Now, when I try to mount he drive, it says this drive contains no volumes os x can read.

From what I hear, diskwarrior is supposed to be good so I don't see it as a bad investment. . .oh well, I'll just keep the drive on the shelf powered off. . .until I find someone who can take a lookie-loo or until I can afford to pay for big-dog data-recovery guys. Probably when I hit mid-life crisis (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Or, 'til I can get some more monies together and buy spin-rite and try again.

Been down this road too many time with other peoples stuff. Its not a warm and fuzzy place ;-)

Its hardware. No ammount of special SOFTWARE readers may be able to recover the data.

The most common failure of these drive is the controller board. Not the one on the motherboard but the one on the drive.

PROCEDURE.

Ground yourself. Unplug, yada yada yada

Open the case and peel off parts till you have the drive in your hand.

From an IDENTICAL hard drive (same part number, even the revision number) swap the controller card with a tiny torx driver. Fry's has em.

Reasemble and mount the drive.

After recovering the data move the controller board back to the good drive and use that as your production drive.

Cost: One hard drive you needed anyway.
Odds: 7 out a 10 work fine this way.

Let me know if ya need a better walk through.

Hello,

I was just about to try and remove the drive from the Firewire/USB case and plug directly into my IDE controller when I realized my 500Mhz G4 can only read ~138 GB drives with it's internal IDE controller. . . or some number like that . .

So I stepped back, and scratched my head and put the drive back down.

I guess I could try to find enough bravery to replace the controller. . . although I don't REALLY feel like buying another one of these Maxtor drives and at the rate these things change. . . I don't know if I'll be able to find the same drive anymore.

Chung,

We were talking about your problem over lunch. Here's three options we came up with:

1) Do you have a spare smaller drive laying around? Install it in the enclosure end hope the problem still exists. If it does, get another external enclosure and that should solve things.

2) Do you know anyone with a newer machine? Ask if you could install the drive on their machine to see if it is okay. If it works, then you just need to replace the external enclosure.

3) Go out and get another enclosure and test the drive in that. I liked this option least because you'll have to spend the money for the enclosure without knowing if it will solve the problem.

Let us know how it turns out.

Thanks Ed,

I'll try to find someone with a newer mac. I wonder how "newer" it needs to be. guess I can google and find out.

Unfortunately, all my "extra" drives are SCSI because my studio's hard disk recorder only uses SCSI drives. This one was backup.

Dude, you're over your OT limit! (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) How's your 914's? Did you get your 930 flipped by RH?

Another OT: Do you know a good inexpensive architect?

As far as Macs go, newer OS generally means newer hardware. If you are on OS 9, look for someone with OS X.

FWIW, a PCI ide card only costs about $30.
