dit is het advies van support synology , is dat oke ?
als het een hd is , heb ik het volgende geprobeerd , steeds opstarten , en er 1 hd uithalen , dat gaf geen succes
If with HDD and DS can start, then likely there is bad HDD.
If you mean you have obtain a spare HDD to install alone on DS and able to install DSM and login DS UI?
If so, please try below:
If the motherboard is fine, and you were using RAID1/5/6 or SHR/SHR-2 or Basic volumes, you can install DSM on a spare empty disk and then insert the remaining hard disks to read the data. (Please be advised that this is still risky. If one more hard disk fails during this procedure, then your data may be lost). Here are the steps:
1) Power off and remove all hard disks
2) Insert a spare empty hard disk in Slot 1
3) Power on and install DSM normally
4) Do not create any volumes on spare HDD. Power off DiskStation once DSM is installed successfully.
5) Insert the remaining old hard disks while keeping new spare disk in slot 1. (1 of your old hard disks may be left out.)
6) Power on DiskStation
Once the data in the old disks can be read, you should back them up to another place asap. Or, you can go to Storage Manager and repair the system partition on the old hard disks. When it's done, you can remove the spare disk, install the original disk, and repair the system partition on the original disk. By doing this, your previous system configurations (user account, user privilege, application settings, etc.) will be erased, but the data in the shared folders will still be there
Please run SMART Extended test on all HDDs, ensure they are all healthy.
