1TB WD became unallocated

Greetings,

It is about my WD 1TB External HDD, which became 931GB unallocated after I wrote .img on it's partition (bymistake of course). It had 1 partition only of 93x GB and I had to write that .img on a sd card drive using WinDiskManager. But unfortunately, I didn't check partition and it was written to my 1TB

Anyway, as now it has became unallocated and I was reading sevenforum and I don't get what is the best and easy way to recover the partitions and DATA of course.

Any help would be really appreciated. BR

Tell us more about WinDiskManager - exactly what click choices were made to get that image onto the external hard-drive? If WDM did not quick-format, then perhaps the folder structure and the data file names just might be intact. A quick-format will wipe out the "post office" that contains the addresses and names of the deleted folders and files. The well-known "laziness" of copy operations ever since earlier DOS and Windows may work in our favor of data recovery.

Hi, the program was actually: Win32DiskImager.

I just selected .img and click write.

There are any number of partition recovery utilities, and a lot of data recovery utilities. I don't know what Win32 DiskImager / ImageWriter did just before it made the IMG onto the external HD. Or, did you have Win32 DI/IW take an image file, an ISO file, and create a bootable device?

Hi, yes, an ISO/bootable type file. This was img: IMPORTANT: How to repair filesystem after format, etc - GSM-Forum

Probably that did a quick-format on that external HD; we're left with data recovery that will search the entire HD, looking for recoverable files, much like gathering up car parts from all over the junkyard.

Thanks for your help. So where to start from? Which software will be good enough recover files?

Edit: is it formmated and I need to recover files now? Or recover the partitions?

I've heard that good results come from TestDisk's PhotoRec, however, I do not know how to walk you through that. Others in the know will have to enter in and help.

Okay. I check with TestDisk and PartitionWizard tool. Is it partition that I have to recover now or is it formatted and need to recover files? In Disk Managment I see 931GiB unallocated. But nothing in Computer as Drives.

If you recover the parition the files should then appear
