Restore access to unknown hard drive?
Hello,
For a few days now, I've lost access to my backup hard drive. In Device Manager, it appears as an unknown device. So, somehow, it's still there. When I start my Windows computer, I can hear it running (HDD).
There are thousands of great programs on the internet that promise to save your data. Ultimately, of course, they all cost money, or the highly touted programs simply can't find the hard drive.
Has anyone encountered this problem before? Is there a way to recover the hard drive without initializing it or deleting the data?
Best regards, Leander

What it looks like is the HDD beyond the extent that such programs could still help you.
That sounds like a case for a prof. lab for data recovery. We’ve got this from EUR 199. The HDD is pretty sure scrap but the data can be saved for a few hundred euros.
The last straw would be using Linux to try to clone the HDD. But that only makes sense if you want the data. This process can take a correspondingly long time and should be monitored as the head of the HDD can fail and then further damage can occur…
Sounds like unstable HDD or even heavier damage. Since Windows can’t use the HDD properly, there’s sometime going up and throws out the HDD…
Like I said, cook yourself with Linux and then babysit for hours.
You say scrap after the one statement from him? Without even considering the plate first to test for errors?
Yes, because I already heard this description at 200 or 300+ plates and it is typical. I’ve been doing this for a few years. 😉
Besides, testing makes hardly any sense – that’s just wasting last chances. Before I test this way, I try to clone the HDD as suggested by me.
Everything else is quash. What’s going on in tests and analyses can you read here: https://disk-doctor.eu/blog/index.php?t=was_fit_bei_datenrettung_mit_software
Even if I’m mistaken – cloning is to be used as a function test and on the other hand as a backup. So it’s the best and safest option.
Jop had read, Habs said in the lower comment. Sure, as I said, I totally understand what you say. It can be fast expensive, so I simply try to help – if possible.
But find it good that there are competent people here & Not only you know – the ones you only get stupid answers.
Yes and the FS has already done – see:
After you appear in the disk management, it will also be in the BIOS.
In this way, they try to give the recommendation which can cause the least damage – therefore clone.
You seem to have read that with the disk management. I usually look at the answers of the others and especially the comments of the FS before I answer. That’s why I saw this before I gave my recommendation.
But even if not – clone and thus save the data is the procedure that best fits regardless of what you see. If Linux and ddrescue can no longer start with the HDD, then DIY is anyway from the table…
Of course you thought that you said that. It’s your nick. I am also employed in the IT field, so I also find this description quite often. That does not mean that I would recommend this way to everyone immediately.
You can be right, too. But also not…Therefore I would at least try to find that way. You don’t have to go directly to the board but you don’t have to look into the BIOS and the data carrier administration.
Hi! The fact that the hard drive is still recognized by Windows can already pass through a USB to Sata adapter without the HDD itself still working.
Only if the capacity and the model are still displayed correctly in computer administration or bios means that at least the ID of the hard drive is read correctly and you can try it with your own software.
Laiensoftware is available here, for example:
1. Partedmagic: Here you start a Linux operating system over a usb stick.
Two. R-Studio: already includes some features like professional software.
But note:
1. Do not describe the hard disk (also not CHKDSK).
Two. In case of any grinding, crumbling or peeping noises cut off and no longer try to continue. Otherwise, there is a risk that the surfaces are damaged, which is also irreversible for professional data recovery.
3. Never open the HDD itself (especially when the engine runs -> reading heads are NOT stuck on the surface).
There are the following possibilities for professional data recovery:
1. Exchange read/write heads.
Two. Patching the ServiceArea (e.g. Module 93 at Seagate, 01,02 & Relo at WD) so that the HDD is no longer stuck in the so-called “BSY” status).
3. Repair other modules from the ServiceArea
Otherwise, my tip would be if the HDD used a USB to Sata adapter to test another.
The professional data recovery of a 1TB hard drive costs everything 300€ (only after success & already incl. taxes).
Okay. So you have two hard drives. One with the Windows and the one that is no longer recognized, right?
But if you connect you now again, the PC still starts normal?
If it doesn’t get 99.9% – when it comes to the data you shouldn’t gamble around and try to get the HDD running. Especially in Windows as background services such as CHKDSK can cause further damage, especially in connection with the background processes on the HDD, which then maps out defective sectors, etc.
All this is not desirable because it can worsen damage!
Well, what’s normal. He needs a little longer.
I have 2 SSD’s and 2 HDD’s. The SSD’s for operating system, programs and games that can stay HDD’s for data that can lie.
Without the broken HDD, the PC starts quite normal, like any other. However, it is also not about the starting behavior of my computer, but about the data on the “unknown” hard disk.
Okay. Can you see at least in the Windows Disk Management? Or the partitions of it?
Did you connect a new device or updated any drivers?
No, nothing like that. At some point, my PC didn’t want to go up as usual, it’s gone forever if it worked. Once he ran, I saw that named hard drive is no longer displayed. Then I removed it and then the computer ran quite normal again.
Also in the data carrier administration, a data carrier (1) is not initialized as unknown/not initialized.
Hi! If the computer takes forever when starting, it’s due to the fact that the defective HDD is stuck in BSY status and the computer waits until the HDD gives your ID from itself. As a rule, the computer breaks off after 30 seconds and starts without the HDD.
Ah, this comment. All right. And in the BIOS directly?
