Hello, I hope this is the right forum to post this to.

I have dropped a WD Green 1TB WD10EADS from table height onto a carpet while it was on.

When I connect it using a SATA-USB adapter to my linux box, a debug message is sent to kernel in 2min. It detects the HDD as 2TB even though it is 1TB, but it is not able to get any more info out of it.

When I connect it directly via SATA to a Windows box, it shows up in device manager in 1-2minutes as "Unknown device", in device details, it's ID is something like SCSI/SCSI_____

When connected, the HDD doesn't make any strange sounds, it starts spinning and it makes normal HDD sounds when spinning up. I have given it to a shop(they aren't what you would call data recovery pros) that has a PC3000. And as I seemed to understand, it didn't detect the hard drive, but they said that "it seems that the heads are okay".

Nearest city with a data recovery center is 200km away.

Can anyone give me any clues what is wrong with the HDD? It contains extremely valuable information that is not backed up(I know, that's very dumb). I already purchased 2x 2TB Seagate NAS drives for a RAID array.

What's does it mean "it seems" ?
Do they open the lid ?
I hope not !

Needs proper diagnostic to determine the problem

(I assume its not the answer you hoped for but...)
Considering that:
Then its highly recommend to send it to a DR pro.

Если диск упал включеный, то сами вы ничего не сделаете. Точнее сделаете хуже, если будете подключать то туда, то сюда и носить в места где не могут восстановить информацию. Каждое включение вредит драйву и уменьшает шансы на восстановление. Нужна информация - отправляйте тому, кто точно восстанавливает после падений. Если нужны контакты в России, могу дать.

Есть в Краснодарском крае знакомые?
