Question Is my hdd PCB board failed?

[sorosh20]

I accidentally changed the format of disk to ext4 . Which is not a format that windows supports.
And even installation disk doesn't recognize my hdd.
But my hdd was healthy before .
I told my friend to connect my hdd to his motherboard and check if the drive appear on disk management or not .
But it didn't show on disk management.
The thing that make me confused is that hdd is spinning normally , no weird sound, no sign of physical damage. Is my PCB board good ? or is it the partition format that make my hdd broken?

After changing it to ext4 windows didn't boot and even windows installation dvd doesn't recognize the hdd.

If you cannot retrieve a SMART report, then the drive has most likely failed.

In any case, this is not the typical symptom of a PCB fault.

"HOW" did you change it to ext4?

 

[sorosh20]

I tried to dual boot windows and Linux, so I accidentally choose the whole drive for Linux installing, and because Linux filesystem are ext4 , it formated my whole hdd to ext4 and now I have no idea how to change it back.
Also I want to know if my hdd is failing because of this or not.

during the windows installation does it see the drive at all?

No. I don't see it but my uefi motherboard recognize it . But I can't see it with disk management , it looks healthy but installation doesn't show it.

I have personally used this software and it includes many features and utilities. "

Just personal experience.
Try to convert or format and partition it and see how you go and report results. Cheers

If you use windows disk management and there is a drive listed that says "Healthy" but has no drive letter assigned to it, you need to right-click on it and assign it a drive letter. "Change Drive Letter and Paths..."
