Nope, searched my email for you and here it is:
"MV-8800 freezes when using Mastering-Audio File Utility-Delete in an area where there is no WAV or AIFF file (example: CDIMAGE folder).
Cannot use. Cannot shutdown. Cannot park hard disk head."
I had just gotten my MV-8800 and gone thru basically testing making a CD to check on the reliability of a particular type of CD I'd planned to use with the MV-8800, then blithely thought I could delete the contents and then CDIMAGE folder when I was done.
It was a minor annoyance, but something I figured could easily be resolved in an update, or at least confirmed by Roland, even with just a "Can't Execute" warning (as it should do, based on the file management principles outlined in the manual) in the OS applied to attempting this action.
Here are more specifics from another email:
a) Go to Mastering/Audio File Utility
b) Use Audio File Utility/Delete inside the CDIMAGE folder, to attempt to delete one of the two .BIN files in there (my original error, that I was reporting).
c) The MV-8800 will lock up hard when you use Mastering/Audio File Utility/Delete on the, I believe it's called, CDDATA.BIN file inside the CDIMAGE folder. No other controls, including shutdown, will work at this
point, and the MV-8800 has to be turned off and restarted to get it unfrozen.
d) Once turned off and turned back on, everything is fine -- I haven't had any problems with corrupt files that are evident in any way yet.
e) If I try to use DISK/USB/File Utility to delete the same file, I get the proper "System folder cannot be deleted" error message.
f) So at least as far as I can tell, the issue is that inadvertently using Mastering/Audio File Utility to try to delete the CDDA.BIN file inside the CDIMAGE folder will cause a lockup.
My OCD annoyance was that CDDA.BIN was sitting there on the hard drive taking up space after I was done with it, with no way of getting rid of it.
After a few rounds of email, they did finally acknowledge the problem. Actually, they were very polite on their end; it was just frustrating trying to report this as accurately as possible and at first, just getting a part of the manual quoted back to me in response.
Oh well, old news I hope and maybe fixed with the OS update? The exchange about this above was over two years ago, in any event. Generally, unlike the internet FOO on this issue, I've found Roland support very professional and responsive, which is why it was a bit of a shock not to get a more explicit response to this attempt on my part to help.
Tempest in a teapot, really, but you asked.
Haven't checked to see if this is fixed in the update; I've just learned "not to do that" since then.
