Unchecking "Show SSD drives" only removes the first SSD drive from the list

Pretty much what it says in the title: I have 2 SSD drives in my machine, and when I uncheck "Show SSD drives", only the first one is removed from the list.

I'm using v2.15.741 (64-bit)

thank you for your report. The development team reads all threads though rarely comments unless more information is required. Not having two SSD (or truly even one non-flash-mem type) I can not see if I can reproduce, but I'm sure they'll be able to troubleshoot this.

Is it possible that the version of Windows, and maybe the make and models of SSD's, might be relevant for reproduction ?

definitely the windows version

and make/model of SSD might not be a bad add in

good call @Alan_B

I am running Windows 8 Pro.

Defraggler correctly labels both drives as SSD in the main list (in the "Media Type" column).

The first one (C:\), which is removed when I un-check the "Show SSD drives", is a SanDisk SDSSDX240GG25 (SanDisk Extreme 250GB).

The second one (D:\), which is NOT removed when I un-check the checkbox, is a Kingston SV100S2128G (Kingston SSDNow 128 GB).
