I've used Disk Director successfully before.  This time I attempted to shrink my C: partition so that I could clone to an SSD.  I had 148 Gb on 299Gb that I was trying to resize to 238Gb.  When the dust settled this bleeper reported Corrupt Master File Table.  My gut feeling tells me that 5 years of programs and tweaks are still there.  Does anyone know how to recover?  So far Acronis Recovery Expert, TestDisk and Seagate File Recovery no help.  DMDE shows daylight but what is the proper procedure to work it's magic?

I'm currently copying the D: partition of the afflicted drive just in case.

Help.

When you ran Testdisk click on Advanced then Boot. Does it show that the backup MFT is intact?  Even the backup is actually only a few first bytes fo the MFT so it may not work even if the backup is listed as okay.

 

Also, if you can create a System Repair Disk on another computer with Windows 7 doing a chkdsk /r will try and repair the MFT.

 

You may have to recover your data with a program like Easeus Data Recovery. This would let you recover 1GB for free. After 1GB you would need to purchase a key.

 

This is why I recommend a complete disk image be done when doing any kind of partition movement. Though rare, things can go bad as you found out.

 

I am not familiar with DMDE but I would assume you need to scan the drive for it to find any recoverable files. Here is the online manual.

Thanx for suggestions.  When I click advanced  I only see 4 partitions and only two options, Change Type and Image Creation. NO Boot. Going with Image Creation I get "Image created succesfully but read errors have occurred" and an image.dd in the destination sized 0 bytes.  Now what? 
I have loaded a clean 7-64 install on the SSD.  If I understand you correctly I should make a Repair Disk. However if I boot to it how can I run chkdsk /f on on a disk that windows currently can not access?

You are correct, if the Repair disk cannot see the OS then you will not be able to do a chkdsk.

 

I am not sure why Testdisk did not have a Boot option available under advanced. I never ran into that before. When you ran Testdisk did it find any partitions after doing a Quick or Deep Search? You said there were 4 partitions listed under Advanced.  If so, did you hightlight the partition found and press "p" to list any files. If no partitions were found and there is no option to repair MFT then the only option would be to use Easues or DMDE to recover any files.

 

You are using V6.14 correct? I believe V7 is still in beta. Edit: Under the Advanced Menu there should also be a list option when you see partitions listed.

Thanks.

I hope we're not getting tangled.  I used the old Repair Disk on the failed installation. It saw nothing.  My new installation only sees Local Disk, not accessible.  Is there no chance that the low level functions of a Repair Disk for my current OS might work?

I was using Test Disk 7.0, it didn't say beta.  It allowed you to choose HD OR logical drive which I thought was cool until the dead end.

6.14 is HD only, through Advanced then choose logical partition to rescue. At this point Boot returns:

Boot sector

Status: OK

 

Backup boot sector

Status: OK

 

Sectors are not identical.

 

There is no mention of MFT.

 

Now what?
 

Unbelivabely, last overnight I was copying the files from the good partition to a RAID 1 disk, just in case) and I didn't think to set bleeping windows to never sleep.  When I woke up one partition (the logical drive I wasn't copying to) is asking to reformat.  What's the best way to recover these files?

Is there a list option after you selected Boot? Also is there a RebuildBS option? Having both BackupBS and BS okay and yet sectors not identical is very unusual. One should have been marked bad.

 

Edit: Thanks for the update on V7 no longer being in beta.

 

I think your best option for recovering files would be to use Easeus or DMDE.

EauseUS sees no dir structure.
DMDE is inscrutable.
TestDisk, PhotoRec gets nada.

No hope.

Seagate File Recovery works great for failing HDD's.

No hope for windows assassinations.

In your post #5 you stated that you saw that the Both Boot Sectors were listed as okay. Was there an option to RebuildBS. If there is do that but do not write. After selecting RebuildBS there should be a List option. Select that. Are the files listed?

Its too risky to shrink C: dude,its very possible to get your PC unbootable,why didnt you use minitool partition wizard.it has a function-migrate OS to SSD/HD.just few clicks to move OS to your SSD.and another function-copy partition wizard could solve the other troubles ,totally free .dude
