PCIe Hot-Plug important notes for modern PC mainboards

To make PCIe Hot-Plug work some conditions must be fulfilled:

1. Use Linux kernel version 6.x.
2. You have to use system chipset that supports PCIe Hot-Plug capability. Type in terminal sudo lspci -vv | grep HotPlug. If you see HotPlug+ in output it means some of the PCIe slots are support Hot-Plug. Of course you have to use these slots only.
3. At the boot time any NVMe device must be attached already, in any words a BIOS must to initialize PCIe bridge and attached NVMe device. You can use any working NVMe device as a kind of dummy. As soon as operating system is loaded you can remove dummy device and then attach faulty device to begin data recovery.
