Soulseek for Mac destroyed mh HDD

Hi all,
I use SoulseekQt for Mac and at first place it was working ok.
But once it destroyed my SSD hard disk. i used to download and share from the SSD of my Mac and one morning it crashed. Even after formatting the SSD it didn't work.
The second time i used an external HDD connected with USB and happened the same.

Does anyone know why is this happening?

thanks in advance!

Hi trisatanos
I'm absolutely not in OSX, but I'm pretty sure SLSK is not destroying anything on your System. The MACH/Darwin Kernel (that's OSX to you) forbids any system critical operations from being done without the explicit allowance of the kernel. Not even filesystem corruption can be caused by an normal app, as (right) the kernel is controlling it exclusively and checks all Operations in it. After DOS/Win9x (so Linux, OSX, BSD, Windows, Android....) there's always a protection layer there to control all IO. Maybe a high IO Load is nothing your system could cope with (but a SSD is build for such). Sure your System is stable and problems with SLSK only one of the symptoms?
What version of SLSKqt are you using and what OSX exact? I've read a lot about problems with El Capitan with all Apps I've read, not only SLSK, but that was application compatibility, not hard crashes you describe.
Defective SSDs are not so uncommon in the PC world (much more often than HDs), but that wouldn't explain the USB HD...

Hi and thank you for your quick response.
My MacBook Pro has a 2.0GHz i7 processor, 8GB RAM, 2 SSDs and it's from 2011. OSX 10.11.3
I can say that my system is quite stable as i use it for some video editing and a lot of music production.
This happened once with Yoshemite and once with El Capitan.
I cannot say that it is SLSK's fault but it happened twice when only using SLSK with the results i wrote above.
For the USB3 which is not working i formatted it many times and it runs pretty slow.
Now i'm afraid to use it again.
Please let me know if you think of something else.
Best regards

Hi
as I'm not into OSX at all I'd check the SMART values of the disk. Slow often means bad sectors and retries to read datas which indicates a bad disk.
SSDs are chronical troublesome under some chipsets. When Apple sold you the disk it will surely work until it fails; every additional bought & replaced SSD might be a cause.

Cheers
