Dynamic Disk - Lost Volume

#1 Postby thirdcherry » 27 Jun 2012, 08:20

I have a Seagate ST325082 4AS - 250GB (232.88 GB) Hard Drive
C - 16383, H - 16, S - 63; Size - 512

I had three volumes on it: G:\ and H:\ and remaining space was extended from G:\
To make more room I moved all the data from H:\ and deleted the volume.
Then I extended volume G:\ to the remaining size of the drive.

When the system rebooted, the drive was not found and my data is not accessible.

Test Disk finds the partitions, but won't recover them -- error: Disk is too small.
When I try to correct the disk geometry - it says I should be using 255 for the Heads number.

But this still does not help, the main portion of my data still shows as not recoverable.

I urgently need this data! Your help is much appreciated!

I'd need infos from Analyse, is your current partition table.
If you still have your testdisk.log file, would it be possible to zip and upload it.
Alternatively, you can copy and paste the content in your post.

I was using AOMEI Dynamic Disk Manager to do the volume resize, which resulted in the failure and now lack of access to the disk.

I've contacted AOMEI and they recommend:

    1. Delete the Volumes and partitions
    2. Convert it to a basic disk
    3. Recover data with Test Disk

Does this make sense to do this way?

Thank you so much for all the help!

Re: Dynamic Disk - Lost Volume

#5 Postby Fiona » 01 Jul 2012, 08:41

Has your disk been before a basic disk or a dynamical volume?
Do you want to convert it back to basic?
Your volume I: ends after disk limit.
There might be a trick to get data and probably to resize it.
Like in those examples;
please-help-me-recover-a-partition-disk-too-small-t625.html?hilit=tricky
post2334.html?hilit=tricky#p2334
post1093.html?hilit=tricky#p1093
But before you'd write a partition table. it's advisable to copy/ backup your data using testdisk first.
The Value to extend your disk virtual is 30589!
Please copy/backup your data.
Your OS is Vista servicepack 2.
In your case, there is almost no reason to use any partition manager becaise since Vista you can use the disk management console to resize and create partitions.
But it'll come later.

Using TestDisk on dynamical disk to convert them back to basic, there is no necessity to delete any partitions.
Dynamic disks need no partition table.
They put a signatur of the volume at the end of the disk.
That entry in your partition table;
Current partition structure:
1 P W2K Dynamic/SFS 0 1 1 30401 14 60 488392944

It's only a dummy, so that another OS doesn't try to use that disk.
The partition ID is 42.
What TestDisk does.
If your Partitions are listed correctly for recovery (your data should be listed also) you can use the menu "Write" to write an Intel partition table.
After restart of your PC, your disk is a basic disk again and partitions are available.
That's it!

But now at the moment try to increase your disk (amount of cylinder as described) and list your data.
If yor data are listed, please copy/backup them.
Next step will be to have atry to write your partition table of your virtual increased disk.
Please not, to access a virtual disk on virtual space causes read errors because ther is no physically space.
But it's a normal behavior and often at the and of a disk is free space.

Hi Fiona,

1. My disc was originally a Basic Disk
2. then converted to a Dynamic Disk
3. Then increased the volume size
4. Then attempted to resize volume again after deleting excess volume.

Hi Fiona,

The scan completes, but shows

HPFS - NTFS 0 1 1 187 254 63 3020157
HPFS - NTFS 188 0 1 30588 254 63 488392065 [Work]
HPFS - NTFS 17653 0 1 30400 254 63 204796620 [Portfolio]

The first partition I believe I was using as a scratch disk, and was 1GB partition. Eventually I deleted this partition and extended the Work Partition onto this one, successfully.

Partition 2 - Work - this is the main partition of data that I'm concerned about preserving.

Partition 3 - Portfolio - I had already deleted this volume, and was attempting to expand Work into this area when the drive failed to do that extension. I'm not concerned with recovering this data, I already have a backup of it.

Please advise how to mark these Partitions properly to get my data back. Currently, I only have *, P, and D as options.

Thank you!

I'll have a try to guide you through!
Your disk info were lacking, but I've got it from your first post and the testdisk.log.
Now it looks like that you're only concerned about your partition labeled "Work".

To access your disk, that your partition Work fits, you must increase the maount of cylinders to make that partition accessible.
Please, try the following;
Confirm in TestDisk through until you see Analyse.
Don't confirm at Analyse but Geometry.
Please check Cylinder.
Change the value to 30589 .
Leave the menu at OK
Check Analyse and press enter.
Proceed at Quick Search with enter also.
If TestDisk starts a scan, wait until you see that partition "Work".
Press enter to stop the scan.
Your partition with label "Work" should be listed.
Please upload a screen.
Check that partition and press p to list your files.
But it'd only possible as long as a boot sector is recognized
Do you see your files or an error message.
This is only intended for diagnosing purposes.
It doesn't change anything to your HDD.
Don't use write or anything else!

Please let me know.

Fiona

here's the screen after quick search.

Yes, if I press P I see all my files.

I don't currently have another hard drive to copy to, if I go get an external, will I be able to copy the data to there?
If I write to the disk, will it simply recover the data without me having to copy it to another drive?
Thanks!

Just have another disk/drive etc.. whre you can copy your data to.
It should be working.
Afterwards we can have a try to resize your partition.
But it's always recommended before you go to change anything to your diks/partition to have a backup!
