Creating output file failed & extraction failed: Sansa Clip Zip

[Thrasymachus]

I got the following error:

...
Creating output file failed
Extraction failed!

I was using Rockbox Utility 1.3.1.

Is the Zip writable?  IIRC linux will sometimes refuse to write to disks if it detects an error in the fat32 table.

I tried creating a folder and deleting it before I tried to update Rockbox and it went fine, but I still got that error from RockboxUtility. However, from time to time I do get the problem that it is mounted read only lately. I use pmount to mount.

I suspect filesystem errors. Please check the filesystem, the try again (fsck.vfat)

[Thrasymachus]

I ran fsck correctly at least I think, but I got an error at the end:

nikos@nikospc:~/movies$ sudo fsck.vfat -a /dev/sdb
dosfsck 3.0.13, 30 Jun 2012, FAT32, LFN
FATs differ but appear to be intact. Using first FAT.

After I tried to run Rockbox Utility again, but I still received the same errors(Creating output file failed & extraction failed). I tried creating a new directory, but bash told me it was read only.

So I unmounted, and remounted the Clip Zip again. After that I could create and delete a directory and I added files to listen to. So I ran Rockbox Utility yet again and got the same errors. When I tried to create another folder on my device once again:

nikos@nikospc:/media/sdb$ mkdir Test
mkdir: cannot create directory `Test': Read-only file system
nikos@nikospc:/media/sdb$ mkdir: cannot create directory `Test': Read-only file system

Now I am getting somewhere on this. Apparently Rockbox Utility is somehow turning my mounted Clip Zip to read only. Maybe it does not play well with pmount?

From that log it looks like a lot of the files on your drive are corrupt, so I think fsck was not able to repair the file system.  You should probably just reformat it.

ok, so you have filesystem errors. Things failing in this case is to be expected.

Now I am getting somewhere on this. Apparently Rockbox Utility is somehow turning my mounted Clip Zip to read only. Maybe it does not play well with pmount?

No, this is nonsense. Rockbox Utility isn't capable of (un)mounting anything on Linux. If the Linux kernel detects filesystem errors on a FAT device it automatically remounts it as read only. You should be able to find information about this in the kernel log.

Fix the filesystem errors. Everything else won't work.
