Hello,
strange problems here with my external HD :

while working fine with 3.0 usb port, like on MAC or ps4 , it s not recognized in ps3 and tv (haier) .
i assume that the problem is the 2.0 usb port because the problem happens only when the light is white. with mac or ps4 the light is blue .
when connected to tv or ps3 the HD seems to be working though.

of course, it s FAT32 (it wouldn t work on ps4 otherwise)
any guess?

thank you in advance

What is your question? USB is backwards compatible, yes. Its throughput will be degraded, but still working. I agree with your first guess, it is a disk format issue!

this toshiba HDD has not an usb cable with backwards usb (only 1 male usb ) , so i don t really understand your first answer (sorry, maybe i explained it in the wrong way?)

It looks like the HD is not recognized when i connect it to a female usb 2.0 port ( tv or ps3 for instance).
I just don t understand why, or anyway i don t understand how i can solve this. That s my question in short.

OK, backwards compatible means this: USB3 PORTS will accept USB1 Devices, but will negotiate at USB 1 speeds. USB 1 PORTS will not accept USB3 Devices, as USB 3 devices can only negotiate at USB3 speeds! I hope that makes sense to you. I do not care about a cables gender as they either fit, or they don't, and the cable does not care about what level the USB is.

From here, I believe it is all about what FORMAT the disk is in. Not all devices can read all formats.

You mean format like FAT32? The HDD is like that.
Which is strange that it doesn t work on ps3 (but it works on ps4): ps4-ps3 can read only FAT32 format after all.
