Ive searched a bit and didn't really see anyone with this issue in the old pmd-671 threads. Randomly over the last couple weeks I've noticed very infrequently a few "skips" in my recordings. Then last night while listening to a recording after a show, half way through the second set I got this loud almost exactly like a CD skipping noise, continuously. The strange thing is that I recorded another set of a different show after and that set was fine. When I tried loading it into my computer I got an unreadable error. First time that's happened. I have a feeling it's the card. Ive been using a 32 gig SanDisk ultra, which has been flawless for a year till a couple weeks ago. Ive been formatting it with the marantz and it's been working top notch. Im not the most experienced cf card user so my guess is the card but any tips would be appreciated. Is the card junk, should I scrap it? Is it a fluke and reformatting it again would be the solution. Could it be power related? Thanks for any advice.
