Hello,

I sold my Synology NAS without the drives, the problem is that they were in RAID and are no longer recognized.
I connect them to my laptop via USB using an adapter, they power up fine but are not recognized by the PC.
Do you have a solution?
Thank you in advance.

Configuration: Windows / Chrome 85.0.4183.102

Hello,

Synology NAS run on Linux, so they are formatted in EXT*... Not recognized by Windows.
But they are recognized in the BIOS.

You therefore need to format these disks in NTFS under Windows, for example, to be able to use them.

Hello
Try to "clean" them with diskpart:

Windows Key + R >>> diskpart >>>> ok

list disk
select disk X enter the number of the disk to clean, don't make a mistake
clean
exit

go to the disk manager, create one or more partitions

Thank you for the response. The issue is that I am using a USB adapter on my laptop and the drives do not appear, so I can't find them with dskpart.

Is it really an adapter with a power supply?

Hello,

A glimmer of hope… Windows 10 now allows access to Linux file systems via WSL 2

Explain your adapter, what is it like..?? And also what is the brand and model of this disk..??
The problem is probably that it doesn't have enough power to work, especially with a laptop.

If you have a desktop, even an old one, it would be better to install it inside as a secondary disk, to do that...

It's an Inateck adapter from Boulanger with a power supply that works very well with other hard drives.
I no longer have a desktop, just laptops.

I have already had this kind of problem.
The disk format is not standard.
I used dd if=/dev/zero of=/dev/sdx under Linux
to completely erase the first sectors.
After that, it worked.

But this is to be reserved for experienced users.
A mistake can cause damage.

Do you have a clear tutorial that could help me?

I hope you have a bit of Linux knowledge; otherwise, it might be tricky.
I'll repeat, this is a dangerous operation
If possible, boot from the USB drive, disconnecting ALL the disks except the one to be cleaned
boot the PC with a Linux live DVD/USB stick.
There are plenty of tutorials on how to do this.
Once booted, do the following in a terminal:
sudo fdisk -l it's a lowercase L
In the list, identify your disk based on its size
There will be entries like /dev/sda1, /dev/sda2, /dev/sdb1, /dev/sdb2, etc.
for example /dev/sdb
You need to choose /dev/sdb, without a number after it.

Make sure you do not select the wrong disk; otherwise, the damage is irreparable

type dd if=/dev/zero of=/dev/sdb bs=1
Let it run for a few seconds, around 30 seconds for example, then interrupt with CTRL + C
run fdisk -l again to check; the lines concerning /dev/sdb should have changed.
turn off the machine
You can now boot normally and use the disk.

If the goal is to wipe the partition table, this should do it more cleanly: 
dd if=/dev/zero of=/dev/sdX bs=512 count=1

Where X should be replaced with the correct letter corresponding to the disk...

And since we're starting on a Linux LiveUSB, we might as well use Gparted to format the disks…

I'm not sure that erasing the first sector will be enough, but why not.
For Gparted, that's fine, but if the person is more comfortable with Windows, it will be easier. :-)

I am aware that the proposed method is not the cleanest or the most efficient...

The site says that this adapter does not come with its power supply... but only the port...
and that it requires 12 volts at a minimum of 2 Amperes...
https://www.inateck.com/fr/hard-drive-accessories/inateck-ua1004-black.html

Not having the hard drive references, we cannot know its energy needs...

Check out this site with "Minitools partition wizard" https://www.minitool.com/fr/disque-partition/formater-lecteur-c.html which should also be able to format this disk... if the adaptation conditions are met.

Try using specialized software like Raid Recovery https://www.diskinternals.com/raid-recovery/. This program works with all types of RAID arrays and will help restore the disk structure.

attention... the RAID of Synology is quite particular... moreover, this client is not looking to recover his RAID... but only to format the disk for Windows..
And the discussion he started doesn't seem to interest him anymore...! He must have found a solution and not told us about it..

Hello

Many people consider forums like this one as a free for all
You find the solution (or not), and then you just leave without having the minimum courtesy to come back and give updates.
It’s unfortunate anyway.........
