Windows 7: Lost partitions!

Lost partitions!

Asus S200E notebook Hitachi HTS545050A7E380 500GB HD D: partition was empty except for 1 directory with some pictures and docs. As you can see, it was about 258 GB. I created 2 Acronis Disk images as I progressed (one of which was a preliminary image and included all partitions except for D:, where I placed the ATIH images.

All images were created from a boot USB key). I noticed some intermittent sluggishness, but it seemed to run better after I cleaned McAfee and other junk off. However, when making a final baseline image, Acronis refused to write to partition D. Rebooting into windows revealed that the partition showed as full.

I ran Partition wizard from windows (no CD drive). I accidentally shut the window in the screenshot, so I guess I would need to run it again to try and repair it, but wanted to solicit advice on my next step. It looks as though the disk is about to go.

1. What is the deal with all of the lost/deleted Boot volumes?

2. Should I allow PW to try and repair it? Some other software?


3. I would like to remove the drive to create another whole disk image since the disk images I previously created seem to be lost. Any issue with that?


I think it likely this drive is beyond help (although it does boot and run).

Thanks for any suggestions!

The free space is wrong in these images.

You seem to have done substantial modifications to your ASUS S200E notebook. Can you please let us know what was the original specifications including the OS and what all you have done on that laptop without missing even a single action.This will definitely help others help you.

Hi Jumanji. Yes, there does appear to be significant changes made, including additional partitions. Unfortunately, this notebook is refurbished and was recently bought by a friend of mine, so we have absolutely no history (or warranty). Fortunately, I was able to remove the drive and image the OS partition, which is the only partition that contained any kind of reconfiguration that my friend deems important, so not too big of a deal if the drive fails at this point.

I am trying to save it, though (and deal with a tight schedule of my own ). It doesn't look as though that will be possible. This morning, I have removed the drive and am re-running partition wizard on the disk via a drive dock and the boot CD of PW.

I'll likely allow the recovery wizard to attempt to recover the lost partitions (although I'm not hopeful), but am confused by the 3mb boot sectors and the 50+ MB FAT32 partitions.

I guess the question would be, should I try to recover those? I think I'll find out in the next hour or so when the scan completes and offers the opportunity to recover them. If not, a replacement drive will only be around $60, and my friend will not really lose any data (unless aproblem occurs restoring the win8 OS partition and system partition). We don't have a win8 disk or COA, but used magic jellybean to find the product#.

In the meantime, I'm considering this a learning experience. If anyone has any advice re; recovery of these small boot partitions, I'd be grateful.

Again, thank you for your response.

I have many thoughts running in my mind on your above post. I am already burning the midnight oil so I may not dwelve on it since it is giving a confused picture.

To be brief
1. The drive carries GPT partitioning. I do not think Partition Wizard is going to be of any help here.

2. I would advise you to try rewriting the GPT header and GPT table from the backup in the drive. ( Hopefully it is still there in tact)

Please refer to this thread and my posts therein especially the one dealing with how to save the backup that may remain in the last 33 or 34 sectors and restore them to the appropriate sectors in the beginning. External HDD suddenly requires formatting, read as RAW instead of ntfs ( Please save the first 33 sectors first, numbering them as Sector 0, sector 1 and so on before you rewrite the backup there so that you can revert back should it become necessary)

Hopefully it should restore some originality to the drive and with the correct partition information available now, the RAW drive/partition may perhaps get restored automatically.. In any case you will not be writing any thing to the data sectors and so the data should remain safe. Once this restore GPT Header and GPT table is done ( Please do it carefully with due diligence), you may think of any data recovery if necessary.

Thanks for your continued assistance, jumanji. I haven't done anything to the drive aside from diagnostics as of yet. It passed the SeaTools short and long test, and I did manage to image the entire disk with ATI 2014.

When I allowed windows 7 to start with the drive in the dock (not as boot), chkdsk popped up and declared that the MFT was corrupted. It couldn't repair it.

Your advice is a bit over my head. Does the corrupt MFT change your approach? Even though I have all partitions imaged and validated (and hopefully viable), I'm unsure of the best direction. When in the notebook, the drive does boot into windows. The 258 GB partition (D: in the 1st screen cap) shows, but is inaccessible and asks for formatting.

I would just delete the other partitions, enlarge C:\ and give him a data and storage partition, but I'm unsure if the MFT issue would be resolved. Also, I have no experience with GPT, adding further uncertainty.

It is very difficult to answer your questions because of the many unknowns. (For example we don't know the partition structure as it existed when your friend got the refurbished notebook. We also do not know what your friend did and what all changes he made to the partitions and how.)

Now the question is what is your real goal?

In which partition is the data you want to recover?

If you say D what exactly is the important data you or your friend want to recover? Or you just want to make D accessible? That is turn off the RAW indication.

As I understand it was fine before and turned RAW when you tried to write some image into it.

Now to turn it into a basic question why did your friend give it to you? What was the problem then?

You see these were the thoughts running in my mind yesterday night which I tried to bottle up and get going.

Referring to the PW screenshot you had put earlier I have many more questions on it but I am aware there is no point in putting them up to you for yourself is unaware of it.

We are literally in the woods without even a basic compass to give any bearing.

So the first attempt is to see whether at all it is possible to get some bearings?

Trying to rewrite the GPT header and GPT table as I indicated in my last post is that attempt.

Now it is possible to try MFT repair with Test Disk Advanced NTFS Boot and MFT Repair - CGSecurity but the question is should you try it now?

My answer is no. Not before we get some bearing. ( The drive is OK. And you may be able to clean install Windows 8 if you so desire. No need for a COA since the unique product ID is embedded in the BIOS. May be mate theog and other experts can help you doing that. So keep it as an option. You may raise a query on it in Windows 8 Forum)

While you can answer the many queries raised in this post, using Bootice is not all difficult. Please wait for my next post which will explain how to go about it.

I need sometime for the writeup.

Download Booticex86.rar / Booticex64.rar ( version 1.2.0) http://bbs.ipauly.com/viewtopic.php?f=2&t=2 as per the system on which you will be running it and extract it to a folder say Bootice. Run the exe file.

EDIT: 09 Sep 2015 The link given above no longer works. Download your Windows Bit version of bootice from Bootice Download Softpedia

EDIT: 08 Feb 2016: You may download the current version of Bootice from the author's website €BOOTICE v1.3.3.2: ŠŸƒ强大š„启Š维Š工…€‘-*€轩

Select your drive and click on Sector edit.

Clicking on the Partition button will show all details. Please note those diligently. Clicking on an entry on that drop box will show the contents of that LBA (sector).

Lost partitions!-b03-11-2013-11-53-07.jpg

The following screenshots will help familiarising with the functions. Not a rocket science.

Lost partitions!-c03-11-2013-12-09-25.jpg

Lost partitions!-d03-11-2013-13-00-46.jpg


Saving any sector is an important task. You will start saving LBA0 (Sector 0), LBA1(Sector 1) and so on upto and including LBA33 and also all the Partition LBAs shown. You can use the arrow keys to navigate to the first LBA namely LBA0 and save it. Then you can increment it with Next arrow and keep saving each sector till LBA33.

For the Partition sectors, click on the Sector Indicator field, type the LBA number and that should take you to that LBA. You can also get that sector by clicking on the entry in the Partition Button drop box as aforesaid. Please save them with distinct naming such as LBA0, LBA1, LBA2 ………..LBA33 and so on with the LBA number.

Note:
1. This saving exercise is only a preliminary action. Should it become necessary anytime to bring the HDD to the condition we started with, these sectors can be restored.

2. There may be some sectors with no data – all zeros. No need to backup those.

To save any sector, click on the back up to file button, give the distinct name and click on Backup. By default the file will be saved to the folder where you have bootice*.exe. Check it when you do the save first time. ( You can also save it to any other folder, by selecting the folder, giving the distinct name and save. You can experiment if you want to.)

Lost partitions!-g03-11-2013-18-39-03.jpg

Now starts the real work of saving the sector backups that already exists in the last 33 sectors.

Check the last sectors of your Disk from n to n-32 with Bootice. If you find that the GPT backup exists in those sectors, save each sector starting from n to n-32, giving a distinct name as nLBA, n-1LBA and so on. ( Do not replace n or n-1….. with actual LBA number.If you do so, you will be confused as to which LBA is to be restored to which LBA. Follow the instructions literally.) ( I have named the last sector as n sector but you follow it as nLBA, n-1LBA etc........... So read n sector as nLBA in the screenshots. )

Lost partitions!-e03-11-2013-13-37-57.jpg

You will not do anything with LBA0 which is only a Protective MBR. Leave it alone now.

Now restore the nLBA to LBA1 (sector 1), n-32 to LBA 2, n-31to LBA3 and so on till you complete n-1to LBA 33.

Once this backup restoration is complete, check whether your HDD is accessible.

Now on how to restore using Bootice:

Select LBA1(Sector 1). Click on the button Restore from file, select the backed up nLBA file and click on restore. Now n-1 to LBA33, n-2 to LBA32 and so on till n-32 to LBA2

Lost partitions!-f03-11-2013-14-22-28.jpg

At the end of it, let us see whether there is any light at the end of the tunnel.

Even if not, I would think your HDD is now in a better condition for any data recovery – PhotoRec, Test Disk, Zero Assumption Recovery , Getdataback, icare data recovery or whatever.

Good morning, and at the risk of sounding redundant, thank you again for your tenaciousness .
I have to run out for an hour or so, but wanted to respond and answer the questions in your response from last night. Your latest post is very impressive and I will dive into reading that when I get back. On to the questions:

Quote   Quote: Originally Posted by jumanji View Post

I don't think it important to my friend if no other partition than C:\ survives. The only other partition that has (had) data was D:\ (depending on the environment, either 100% free or 100% full), but that seems to be lost. No worries, as it was just copied from another system, so all is intact elsewhere.

So the 1st priority is C:\. It actually seems fine, boots up, etc. I could delete all other partitions aside from C:\ and the required system partitions and be fine, as would my friend, but I'm not sure which partitions to keep.

I would like to keep the boot drive intact (or properly restored via ATIH) and repartition the space regained from the other partitions into useful partitions (no recovery partitions required, as I'll maintain a base image for him). I guess all new partitions would need to be GPT?


On an MBR drive, I would have no problem deciding that, but here, there seem to be multiple partitions that could be required, and they read as mixed FS (i.e., most NTFS, a few FAT32), EFI, etc.

Quote:

Well, the partition was readable and writeable, but in hindsight, the system was sluggish, the images took longer than expected to write and acronis returned an error or 2 (could not save file in existing format or filename), but did write, at least until it stopped. It wrote 2 full images to the drive and I even restored the OS image once. Then the partition was gone.

Quote:
why did your friend give it to you? What was the problem then?
HE was having trouble getting online (this was a router issue) and wanted me to clean the system up, etc. He did note that it was sluggish.
-----------------------------------------

I also view this as a learning experience, but of course, the important thing is to get it back to him in one piece, streamlined and efficiently partitioned.

I very much appreciate the time and effort it took to participate in this thread and the time involved in the "tutorial" in your most recent post.

But now that there is a bit more clarity, I will await a reply from you before diving into the process you outline below, which seems very interesting. I'm hopeful that there is a simple solution to this, but even if so, I will retain and experiment with the information in your post.

I will be back in an hour or so.

I just found out that I will be tied up until later this evening. Also, I hope that you didn't feel pressed to give up your Sun. aftn for this. Of course, it is all as your time permits. And thank you again.

I'm thinking I may try restoring just C:\ and the system partition Acronis attached to it for imaging.

Hi Jumanji,
After taking a step back and reassessing the situation, I decided to delete and recreate the D:\ partition. This seems to have cleared up a lot of issue. Performance is back, I'm able to write to the partition, etc. Everything seems fine. However, running a PW recovery scan does still show some issues, as per the screenshot:
