Okay, this is my WD 3TB problem.

#1 Post by Deity666 » 05 Aug 2014, 19:07

I bought a WD30EZRX (-00D8PB0) 3TB around November last year and must admit my knowledge of Advanced Format drives and their issues with XP Home was...lacking. I had to call WD for help using their software - which I understand to be a stripped down version of Acronis to install it. I can't remember if the tech simply helped me create partitions on it or started me on formatting as well. I don't know if the sectors needed to be aligned or not.

I want to say the first partition was a little over 2TB with a 2nd one of 740+. One day, the first partition disappeared. I suffer from chronic pain and lack of money, so since I had already started using the 2nd partition, I recovered as much of the info from the first as I could instead of trying to recover the first partition. Under the heading of "No good deed goes unpunished" I decided to clean up my system, reconnect cables to make things tidier and voila, the 2nd partition vanished as well. Testdisk has once again allowed me to recover as much of the data as I had room for.

I have been working on this for a few weeks - between reading about it, trying things I've read here - and the best I've been able to get it was being able to access the data. So here's where the journey starts with images and descriptions - it's ongoing, so maybe I need help more than I thought when I started capturing the images last night.

After the initial launch of Testdisk 7 (I've also tried the earlier 6XX), I selected the 3000 GB drive from the list of drives. The page said it detected a EFI GPT partition, and since I've read that that's what I should try, I selected it.

I selected Quick Search. This is a moment in time of the process.

I can't seem to add another image. Will continue.

My guess is the drive has three partitions, a small Acronis bridge that allows for XP to see the larger drive, than the two real partitions. I'll be righteous and admit I'm wrong if it's explained. By no means do I think I know everything - in fact I'm struggling just to try to understand this.

This is what existed of the Testdisk.log at time of making it with a slight update to it when the mention of a floppy disk is listed - I put one in my drive to see what was on it.

Physical drive 4 is the one I'm struggling with.

After getting to ~76% last night, my system locked up and rebooted so I'm back to an earlier point than I was.

Fiona or Chris, I'm hoping you've looked at this and since you haven't seen something big time wrong, is just waiting for more before saying something.

After a mistake Thursday morning that caused me to have to restart the process, I did and it finished a short while ago.

I have not yet tried to see if either one will list. If I haven't included this in previous posts, this was never going to be a bootable drive, but I know it had two main partitions, maybe a third just created by the Acronis software. The first was 2+ a small amount and the other 740+ gigs. It worked fine for months,and then whether it was going from the free Acronis to the Seagate I had to install - which requires the uninstallation of the WD - or the installation of the retail copy I bought or none of these, I don't know. It may even have had something to do with BIOS changes when a different newer boot drive died and would not show up and I changed a setting - I didn't know it might have mattered.

I think what will happen now if I choose with one and get the option to look at the contents, I might be able to. I also know I might be at that stage that if i hit 'Q' to exit the choice, it throws me back out the analyze screen. Considering how long it took, I'm really hoping for a few words of advice from you before I try. It's 12:10 AM time which means Fiona, it may be 10:12 already for you? I'm going to watch a 60 minute show and then see what happens then, but it's past bedtime for me now - not meant to rush you by any means, just to let you know that from someone so interested in getting help, I;m in a number of different time zones than you. :oops:

So, Christoph?, how hard would it be to build in a 'save' position feature, so after 36+ hours of doing a scan and you press the wrong button, you could resume where you left off instead of having to do the entire thing all over again? Why, you ask?... Maybe it did better than not, but I thought I was at a point where I was willing to gamble writing a partition it had found, "unable to write" it reported and this time, I only had the choice of deeper search or quit and since I didn't think I could keep my system running for the next 56 hours, I hit 'Q' and was back at the analyze screen instead of back at the partiti

P.S. - am I doing anything wrong not to be getting a response? I know my pictures were not the same size and I have pet peeves of my own when it comes to grammar sometimes, so I was wondering if it was more than y'all being busy or just being long-winded...? :oops:
