Hi, I have a boss BR 600 and when i insert any card it checks the card and then says ' card not supported'. I t used o work fine. However i have noticed that 2 pins seem to be missing inside t

Make sure you're using the correct power adapter or that the one you have is not malfunctioning. I've experienced Roland/Boss equipment blinking (and restarting over and over) when they are not receiving enough power. Sometimes even the resistance caused by too long of an extension cord can cause this to happen.

Your best bet is to contact Roland Support. Here's the link-

Make sure that the SD slot is not dirty, check inside with a light and you may want to blow it out.

You have to format the sd card to the device just like a hard drive to a pc.

I have the exact same problem. All my flash cards worked fine, and all of the sudden, none work. Not even the one that came with it. I am still trying to fine the reason. I bought it eight years ago, that might be it.

I have this problem with mine. I've did some research and with the boss br 600 this problem can arise quite often .it's caused by a faulty power diode apparently except in that case I've never heard ofrom the screen blinking at all (which my 1600 also does) I wonder I'd this problem can be the same for a br 600 as the br 600

Make sure the memory card you use is a MAXIMUM of 1 Gb as larger cards are not supported. Yes, the smaller cards are getting hard to find.

I assume you have tried formatting the card in the BR900... sometimes formatting in the PC's doesn't work. read at this web page:

hdd should not be damaged, if your hd and cd are on same ide cable it might be taking the cd as master and not the hd, ensure the jumper on the back of the new cd drive is set in the same position as the old one was, as test remove cd and boot system, hd should act again as usual. this will show that there is a ide conflict.

my assumption is that your cd jumper should be set to slave or cable select position.
you may have to try each until you find the position that works.

I hope this was useful.

Refer to your BR manual for procedure to format the card. Formatting the card in a PC just doesn't cut it.

Look in your index in the manual for "formatting" or "card"...etc.
