Speed_zgz,
If
[email protected] was the address you used, I would try sending an email to
[email protected]. I believe the acepc email address is still active, but Kamrui is the new brand name of their products, so it's possible that sending an email to the new service address will be more successful.
In the meantime, I hope the admin sees this topic and gives his advice, though from what you're describing I'm reasonably sure that the advice would be sending an email to that kamrui address, as it sounds like the drive may be defective/dead.
On a separate note, though I know it doesn't help you now, when the issue is ultimately resolved I would make sure to setup some kind of backup, whether some online type like OneDrive or something local, like with an external HDD/SSD. Or even just a manual thing where you save your important files/programs on a flash drive each time you use the unit. Again, I know that doesn't help now, and please understand that the advice isn't in any way meant to denigrate you or anything like that for not already having something like that in place. A lot of people don't, and I can certainly understand it not being in place on a system you don't use every day. It's not something we normally think about. To be honest, until I got my most recent main computer in April of last year I didn't either, and that was going on nearly 25 years of using computers.
I hope the email to the kamrui address is answered quickly.
