Testdisk 7.1 WIP Geometry error
Posted: 04 Apr 2016, 22:43
I'm trying to recover a primary bootable partition that has turned RAW using Testdisk 7.1 WIP on a single physical hard drive.
The SMART info is Excellent.
I have not written anything to the problem partition yet.
Error background:
I got a 0x0000006b stop saying the bootcache.cat file needs to be deleted in system32/codeintegrity so it can respawn. But I can no longer access the partition to reach this file.
Method:
Testdisk geometry settings is giving me trouble.
This is one of the most common high end HD's (Western Digital Caviar Black 1TB).
It was split into 2 partitions using the Windows 7 installer.
1. An ~800GB partition with the main install (Win-7 64) (unbootable now and in RAW according to diskmgmt.msc.)
2. A ~100GB backup boot partition (Win-7 32) for moments like this when the primary won't boot.
The storage on the 800GB was 139GB free with the rest containing data.
Testdisk says the geometry may be wrong.

My Bios says:
Cylinders 65535
Heads 16
Landing zone 65534
Sector 255
My usermanual says:
user sectors per drive 1,953,525,169
heads/disks 6/3
bytes per sector 512
Testdisk 7.1 WIP says:
Cylinders: 129201 (??)
Heads: 240
Sectors: 63
Sector size: 512
(To my amateur mind 240 or 255 heads is far too much for a HD isn't it, how are so many little mechanical heads going to fit in there?)
Anyhow, I clicked Analyse on the defailt Testdisk 7.1 WIP values and got:
So it is saying the Heads for NTFS should be 255 but Testdisk 7.1 WIP is reading 240.
I then changed the Geometry by leaving everything on default and changing the heads to 255.
I clicked analyse and got this:
I selected Quick Scan
This is while it was scanning:
When it was finished (it is showing FAT16 and FAT32? Both these partitions were NTFS:
After I clicked continue:
Now trying to list the contents of the first partition using P key for List
and the 2nd partition:
Strangely these files appear to be correct.
Anyhow, so I need help here, the Hard drive data is evident, I just need to know what to put into the Testdisk geometry that is correct. I cannot work with 25 permutations which take 6 hours each to Quick Scan.
I know the drive was split into 3 partitions:
-NTFS ~100 MB System reserved
-NTFS ~800 GB Main Win-7 64 partition
-NTFS ~100 GB Backup Win-7 32 partition
This is the Disk management info:
As a test I let Minitool Partition Wizard analyse the physical disk. This is what it found (which I really don't understand). Sure I had Deamon Tools installed on the main (and the backup) partition, but still why on Earth would it identify so many boot sectors???
