Hot-Swapping a SATA Drive While PC is Running: Is It Safe?

Hello, can you do something like that?
I read somewhere that it is possible, but I prefer to be sure. I anticipate questions like "why don't you turn off your computer"? My ATA disk is corrupted (boot problems).

greetings

SATA drives can be safely attached during operation. When it comes to PATA, I knew that you can not fasten during work, but once fastened it caused the computer to crash.

Thank you very much for your help!

You can easily connect SATA and PATA during work. It's good to accept the principle that we connect the signal cable first, then the power cable. Reverse order when disconnecting. If there is a problem with detection, go to the device manager and refresh.
Only the order in which the power is connected is important. Sometimes I did not want to turn off the computer, so I did.

Mates Saturday and milew gave extremely harmful advice. Pat disks are not designed to be hot-swapped, and the fact that they can sometimes be done without burning the disk and the CD is by no means a reason for giving such advice. SATA drives for hot-swap connection require that this function be supported by the controller, and I doubt that the average user has such a controller in his computer.
In short, both colleagues gave extremely harmful advice and are reprimanded for it. In the case of a colleague Saturday this is the fifth one, so my friend has finished his career on Elektroda.

Maybe it would be worth checking for yourself before you start criticizing yourself. What is not intended for such work does not mean that it cannot be done. I have used this type of method a lot and never had any problems with it. You definitely have to be careful how you connect the power plug, but it's probably logical. The XP system is very good at unplugging and unplugging this way. A colleague writing this post noted that he has a problem with starting the disk and therefore does not turn off the computer. I believe that my advice is absolutely true and correct.

First reading:
http://pl.wikipedia.org/wiki/Hot_plugging

The popular hot-swap drive known as Hot-Swap is only supported by controllers designed for it and supporting such functions. Normally, you can connect the disk in this way to a typical motherboard, but it is not safe if the controller does not support hot-swap function. Connecting to a controller without hot-swap support may work, but does not have to. Therefore, giving advice that you can not know the parameters of the controller and its possible hot-swap handling is harmful! The advice remains on the forum and in a month or a few other users will read and apply it, and thus may damage the disk. Hot-swapping PATA drives is strictly forbidden. Sata drives only work in this way if the controller supports this function. If the controller does not support hot-swap, connecting the disk may result in its permanent damage!

However, I will engage in a polemic. HotSwap is a bit different than what we're writing about, yes, there are special software controllers for that, etc. It works unattended, pulls out, puts in and that's it.
However, I am asking for healthy thinking. What is the difference between connecting the data cable during operation and with the equipment turned off? There is no power here and here. Only when the power supply is connected, the equipment is energized, in addition, refreshing the equipment causes its redetection. I believe that there is no such risk, except for a mistake when connecting the power supply backwards, you can always shoot a bull here.
Anyway, for me the topic is closed, practice and theory are a bit distracting.

Here the colleague is right. I will illustrate it with the following example. Gasoline is a flammable liquid, but you can put out a lit match in it. It just needs to be done skillfully and in the right way. Does this lead to the conclusion that such a method of extinguishing matches can be recommended?
To all propagators connecting live disks:
1. In PCs, all devices are hot-swapped, but some only once;
2. The moderators of this department believe that advising on connecting live drives without appropriate hardware solutions is extremely harmful advice and they will draw legal consequences for giving such advice.

and wouldn't it be better to invest in an external USB pocket for such drives? Theoretically, attaching such a disk is nothing more than a USB connection followed by a switch to such a disk, but the fact is that the disks were not manufactured for this purpose. Personally, I would be more concerned with moving the equipment inside the case while it is working, because a moment of inattention can cost the user a lot. To sum up: if we have the opportunity and do not have to save these five minutes, it will always be safer to turn off the computer first.

I just read my motherboard's documentation and it says hot-swap.
Thank you for all your help, the topic can be considered closed.
