Topic: Recording Interference

[F.O.Bean]

i CANNOT STRESS ENOUGH you reformat your cards EVERY SHOW, or until it is FULL. NEVERRRRRRRRRRRRRRRRRRR just delete stuff off the card. you MUST ALWAYS reformat once your music is safe and where it needs to be

Care to explain why? The card in my recorder (no, not the crap one) has been in constant use for five years now with nil problems. I have only ever deleted the files after backing them up. The offending card in my OP had been formatted, but not used for recording before.

Well, just deleting leaves things behind and spaces and when the unformatted card tries to write to it, instead of writing on one long sector, it has to jump around that junk left from just deleting and that's how you get errors!!! That's my unscientific explanation anyway

I'm probably overdue a format then! A bit like doing a defrag on a hard drive. Makes sense.

Hmmm, I'm unconvinced: My understanding was that when data is 'deleted', the actual data remains abandoned and largely unchanged on the disk, except that a flag is written, to: (a) make the filenames invisible to the OS, and (b) change the status of those liberated data sectors to 'now available to be overwritten anytime required'. So the HD Write-Heads have no obligation to slalom around mounds of newly-dead data. But there again, I'm always open to persuasion from the better-informed  :-)

Its a proven fact that just deleting leads to write errors. Might not happen EVERYTIME, but it surely happens enuf that I will ALWAYS format my card before a show/festival
