My boss br 900br keeps saying keep power on card testing whats wrong

SOURCE: MY Boss br 1180 ,disk error

before you go out and buy a new hd try intializing your system.
unfortunaly you will lose all saved info, but you will either way. this test may save you some money.
with your 1180 in the off position press and hold the track 5 button below the fader and the redo/undo button that is just to the left of the rotarty knob and below the power button. while holding these two buttons press the power button and continue to hold the track 5 button and the undo redo buttons untill the test menu is showing. its takes about 15- 30 sec. in the test menu rotate the value knob till you see 23 initialize HDD and press ok. this process may take up to 30 mins. if this doesnt fixya then contact roland for a replacement.

This is likely a compatibility issue. Turn power off and remove the card and make sure the unit comes back to life.

SD card compatibility can be a problem.

You might want to go to VSPLANET.com as there is a lot of info on forums about recorders.

Testimonial: "Great stuff.Thanx for the info"

SOURCE: My Boss br-8 keeps saying medium error. It's not

If the disk had music that was not CREATED on the BR-8 you will get the error. The format is incompatible with computer formats.

If the files were created on the same BR-8, then you probably have a disk drive failure.

Try initializing a blank disk. If it will not, then you have a drive failure.

Also is it possible you are trying to read a 250Mb disk on a 100Mb drive? That won't work either.

I believe this takes a MAXIMUM of a 1Gb card... Lot's of luck trying to find one of those these days!

You can try formatting it with the Micro BR but it probably won't do it.
