Yo wats good mpc 1ers!
Ive just been copying and pasting all my song files from my CF card into an mpc folder on my laptop, and about 5 or 6 folders wouldnt paste into the laptop , it kept saying "error: file is corrupt or can not be located" it will still paste the project and pgm files but wont paste some samples ive used. has anyone been thru this???

I find saving and backing up the worst thing about owning an mpc.
any help would be sweet as...

In my experience music gear (and cameras too ;) ) prefer cards that were formatted in the gear, *not* on a PC.

First I'd get another CF card and format it on the MPC.

Load the problematic stuff from the old card into the MPC, and save it onto the new CF card. Be careful to change the card only when the MPC is not accessing it!

Reload the stuff from the new card to make sure it transferred OK, back it all up to the PC and then format the *old* card *on the MPC*.

It seems like the MPC has some serious file system problems given all the new folder crash reports and stuff...

I regularly backup to PC and run Scandisk on the CF card to pick up any problems early... usually (at least on PCs) file system problems come gradually and eventually cause a crash .

Oooohhh.... yeah, I think that is a bad idea. I found that running PC disk diagnostics (scandisk included) made the corruption worse on my system. But if it's working for you then cool. I had the opposite experience.

Penny, why buy a new card? Here's a better idea.... Load up the problem songs (the ones that wouldn't copy) one by one, and save each one to a new folder under a new name. Then copy the new folders over. Then once you have copied all your stuff over, format the card in the MPC, as deranger mentioned.

Then if you want to avoid getting any file corruption from there on out, use the following method. I'll post it again (for the 10th time, and take this opportunity to rant about how many people complain about file corruption errors when I have posted this solution countless times. I guess they must have missed it. Good thing I saved it after the first couple of type-ups) Here it is, the solution to everyones file corruption woes. It looks a lot more complicated then it actually is, I just tried to explain it with lots of detail for those who are conceptually challenged.


tbonus76 wrote:The method I have for avoiding the saving crashes, directory errors, system errors, and the new folder bug involves "refreshing" the directory tree before creating the new folder. I was getting the errors quite frequently, but since I started this "refresh" technique, I have not gotten a single error. Here's what I do instead of overwriting:

1. In the SAVE directory tree, I move the cursor to the folder I want to save to and I hit RENAME, then in the RENAME dialog I hit COPY. This step is only so that I don't have to re-enter the individual letters when I get to step 5.

2. Close the RENAME dialog then delete the folder.

3. Close the directory tree. (At this point, if you go back into the directory tree, you will see that, in fact, the folder you just deleted has magically re-appeared as if it had never been deleted. Going back into the tree is not actually a step I take in the saving process, it is simply something strange I noticed when I was originally troubleshooting it.)

4. Here's where the "refresh" comes in... So after closing the directory tree (step 3), you should be back in the main SAVE dialog. Move the cursor up to the field at the top where you select where you want to save (i.e. MEMORY CARD or INTERNAL MEMORY or HARD DISK if you have one). I then change the option to INTERNAL MEMORY, and then I change it back to MEMORY CARD. That's the "refresh". Now the directory tree correctly reports that the folder was, in fact, deleted.

5. I then hit NEW to make a new folder, then in the NEW FOLDER dialog I hit PASTE (since i copied the name of the folder in step 1).

6. Then I SAVE ENTIRE MEMORY to the folder I just re-created.


I'm assuming this method would work for saving to the hard drive too, but I haven't been able to test that since I don't have a hard drive installed.

As far as I can tell, it is the combination of not overwriting, and "refreshing" that has eliminated the error for me. since I have been saving like this I have had ZERO errors. Give it a try and let me know if it works for you.

I would recommend a backup and reformat if you have been having the error a lot because you probably have some corruption already on the disk which could cause additional headaches later.


I guess step 1 should have been the format, so you can start fresh, but you get the idea.

Thanks for reposting how to avoid the problems! I haven't seen this yet ;)

Why a new card: to be on the safe side :) *generally*, if you save stuff to a corrupted drive/card you risk more corruption - it's better to save it on a known "good" medium. Your post (last paragraph) implies that as well:
"I would recommend a backup and reformat if you have been having the error a lot because you probably have some corruption already on the disk which could cause additional headaches later." ;)

Still, it depends on the nature of the MPC1000 file system bugs - it may work OK...

The corruption is corrupt data on the card, not a corrupt card itself. That is why I said to format the card to start fresh. The card is not the problem, rather, it is the bug in the MPC saving process that causes the corrupt data. That is why I said not to buy a new card... it's not the card, it's the data on the card that is the problem.

I agree about the card not being a problem, but there can still be trouble from saving to a card with a f***d up file system. I've had to reformat several (physically good) disks and reinstall Windows because of file system errors that went unchecked and escalated to a sys crash and file loss, that's why I recommend *not* to save anything to a card with problems - you risk more data loss...

Just my paranoid opinion ;)
