Yosemite cannot detect SD card I know their is a flood of these questions but I have a late 2013 macbook pro with yosemite 10.10.5 installed on it.

My problem is it won't read some of my SD cards, i've run disk util with the pny sd card inserted and I get this

bash-3.2$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *121.3 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:          Apple_CoreStorage                         120.5 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                  Apple_HFS Macintosh HD           *120.1 GB   disk1
                                 Logical Volume on disk0s2
                                 F57E540D-B47C-40C6-BDE1-F9EEB04734AB
                                 Unencrypted
bash-3.2$ 


Whats strange is when I insert another sd card (a samsung card) It comes up OK 

bash-3.2$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER

I've tested the PNY cards in my iPad with an sd card reader and the photos come up OK, and all the photos appear on my camera as well so the SD card themselves seem to be OK
It's fairly common for recent MBPs to have somewhat glitchy SD card readers. With certain cards, and especially with cheaper microSD adapters, I have to make sure I don't push the card all the way in or it might either not show up at all, or show up but keep getting ejected mid-write.
