Dear All,
My iomega 1TB usb drive cable pin broke from enclosure circuit,
I bought new case of WD Elements and now windows is showing RAW drive,
I have tried many softwares like testdisk etc but failed ... only R-Studio showed me correctly my three drives and the data is fully intact.
Data is huge on 1Tb and I have this backup in different places which will be headache,
Is there any way I can fix Partition table with some software or something.
Any help will be appreciated.

Attaching screenshot of R-Studio and dmde.

i have tried most of the tools but nothin is workin,
I need to fix partition table but maybe manually i have to fix by writting code,
only tool which worked is R-Studio where I see my partitions correctly with data ... so I did recover everythin ... but i want to try some partition table repair before formatting it and putting data again which is big time consuming.
 
Do you still need help?

The problem appears to be that the bridge firmware in the drive's enclosure is configured with 4KB LBAs. When you remove the drive from its enclosure and install it inside your computer, you expose the drive's 512-byte sectors. This means that sector 0 (where the partition table lives) is still in the same place, but every other sector is out by a factor of 8.

Your DMDE screen shot is showing two partitions.

The first is an NTFS partition (type 07), and the second is an extended partition (type 0F). The extended partition contains additional logical drives/partitions.

The NTFS partition has a size of 0xFDB60C sectors. This equates to a size of 8.5GB or 7.93GiB.

As you can see, this is 1/8th of the size reported by R-Studio (63.43 / 8 = 7.93).

The extended partition, as seen by DMDE, has a size of 0x0D904D15 sectors. To get the actual size we need to multiply by 8 ...

http://www.google.com/search?q=0x0d904d15+x+512+x+8+bytes+in+gigabytes

0x0d904d15 x 512 x 8 bytes = 868.075275 gigabytes

Thanks for replying fzabkar ... maybe you was busy,
I have already formatted it and copied back everything
But still its common problem while changing enclosures ...
If I want to fix it by DMDE or testdisk ... then what I have to do or what I have to modify
 
If you want to switch enclosures, you need to match their sector sizes. Some will be 4096 bytes, others will be 512 bytes.

You could use the following command:

fsutil fsinfo ntfsinfo x: (where x: represents the drive that you are checking)

The following article explains how to distinguish between 512e and 4Kn drives.
