The hard disk is not recognized by the computer The needle is stopped

peace brothers

I have a big problem, my life has been ruined

All my work on the Internet is lost

A hard disk is working, not recognized by a computer, and the needle inside the disk does not move, and the disk is internally circular

But the needle does not move

Yes, I opened it to see it only, I did not touch anything, before I opened it, it worked and a computer did not recognize it

What is the problem, should I change a needle?

I made a mistake, not intentionally, when I opened it, leaving traces of my finger touching an iron circle on the hard disk. If I wiped it with a damp cotton, the data would be erased.

Note: SATA Outlet Mechanical Hard Disk for Laptop

I need urgent help, may Allah reward you

Hi @anouarnahal

Unfortunately there is no DIY solution.

You should not have opened the hard drive. This should only be done in a "clean" room so as to prevent any contamination of the discs.

You may have to contact a professional data recovery service and ask them if it is still possible to recover any data from the hard drive. Be aware that this will be very expensive

As @jayeff said; You should not have opened the hard drive. Even the smallest spec of dust inside there can do serious damage! Data Recovery companies have clean rooms, they actually rival some medical facilities when it comes to clean, and the procedure to go into such rooms is enormous.

I visited Ibas (a Norwegian data recovery and secure deletion company) many moons ago, and even though we got certified by Ibas, we couldn’t go near the clean room. Your data can be saved, no question about it. Ibas’ showpiece is a computer from a war zone that contained crucial data. The machine was shot with fully automatic rifles, filled with glue and then burned along with the entire building they were in. Ibas still recovered over 70% of the data from that machine, it was insane to see in person.

@anouarnahal this "a computer did not recognize it" would be an issue with the controller board of the hard drive, not the internals. This could be very difficult since the fingerprint of the platter can pose a problem. If you need the data, close the drive back up and send it off to a data recovery specialist as suggest by my colleague.

If you decide against this out of whatever reasons, I would suggest that you look for a board for your drive and change that. You'd be looking at doing something like this Hitachi GST Deskstar HDS721010CLA332 Hard Drive Controller Replacement

We don't have any information on your drive nor do we have any pictures of the circuit board so we really can't help any further without more information.

@anouarnahal controller boards are available in the USA. Check places like this or on here as well. Remember to switch the BIOS IC from your controller to the new one. If you have to check somewhere else for whatever reason, look for these details

Model : HTS543232L9SA00

Main Controller Chip: 0A57118

Board Number : 0A90002
