 |
|
Hi all,
I bought today a Creative Muvo TX 256MB mp3-player, which should work in Linux as a USB mass storage device. First I mounted the player and tried to copy one .mp3 file to it, with no success; my computer just hanged for a while.
Then, after browsing of several forums for suggestions, I ran 'mkfs.vfat /dev/sda1'. After that & mount, I managed to copy files to player, and also unmount succeeded. But when I tried to use player, it just said "File system error". When I mounted player again, files were still there; in other words, linux sees them and the player don't.
Manual says, that one should format the player in this kind of situation (using the Format command of My Computer in Windows). But doesn't mkfs.vfat do the same thing? As far as I know, it formatted player's USB disk using FAT16 (which is the filesystem supported by player, says manual).
Anyone got similar experiences? Is there anything to be done? (no, I don't have Windows) |

Welcome to Gentoo!
Here are the stats on my 256MB Muvo nx that may help you when running mkfs.dosfs:
| Code: |
dosfsck 2.10 (22 Sep 2003)
dosfsck 2.10, 22 Sep 2003, FAT32, LFN
Checking we can access the last sector of the filesystem
Boot sector contents:
System ID ""
Media byte 0xf8 (hard disk)
512 bytes per logical sector
4096 bytes per cluster
1 reserved sector
First FAT starts at byte 512 (sector 1)
2 FATs, 16 bit entries
126976 bytes per FAT (= 248 sectors)
Root directory starts at byte 254464 (sector 497)
512 root directory entries
Data area starts at byte 270848 (sector 529)
63408 data clusters (259719168 bytes)
60 sectors/track, 184 heads
47 hidden sectors
507793 sectors total
|
A quick browse of man 8 mkdosfs should lead you to the corect formatting options:
| Code: |
mkfs.dosfs -f 2 -F 16 -r 512 -R 1 -s 4 -S 512 /dev/sda1
|
Make sure that cfdisk reports:
| Code: |
Disk Drive: /dev/sda
Size: 260014080 bytes, 260 MB
Heads: 184 Sectors per Track: 60 Cylinders: 46
Name Flags Part Type FS Type [Label] Size (MB)
--------------------------------------------------------------------------------
sda1 Boot, NC Primary FAT16 260.02

If that doesn't do it, let me know and I'll tar up a disk image and send it to you and you can write it to your muvo with dd. |

You propably meant mkfs.vfat, not mkfs.dosfs (because I don't have such file)? Anyway, I ran mkfs.vfat using the parameters you gave, but it didn't like about the -s (sectors-per-cluster) setting. And when I examined your dosfsck output, I think I know why: If there are 512 bytes per sector and 4096 bytes per cluster, wouldn't that make 4096 / 512 = 8 sectors per cluster?
Well, I then changed -s 4 to -s 8 and it worked. But, the "File system error" when using the player stayed. Below is my dosfsck output. I just wonder, what is that "System ID"? Could it be problem, and if it is, how could I reset it?

My cfdisk output looked quite similar, although the size wasn't exactly same.

I would appreciate it, because this still ain't working  I just wonder, if your filesystem is compatible with mine, because you have MuVo NX, not TX... But I'm still willing to try it. |

Sorry, I was using mkfs.msdos which is linked to mkdosfs just as mkfs.vfat is. Also, it should be -s 8 not -s 4, just a little bad math on my part. I think that you may be able to wipe the boot sector, and erase the System ID by issueing the command:
| Code: |
dd if=/dev/zero of=/dev/sda bs=512 count=1
|
But then again, I'm the one that thought that 4094 / 512 = 4.
Anyways, here is a bziped image of my muvo NX, that you can restore to your player using:
| Code: | bunzip2 muvo.img.bz2
dd if=muvo.img of=/dev/sda bs=512
|
Which should give your muvo the exact same filesystem as mine. If that doesn't work you'll have to find a friend with a Windows box and use the Creative utilities to update the firmware, which will also format the player. |

That's what I did and now the filesystem should be fine (the player regognises .mp3 file I copied from my friend's computer). When I plug the player to my linux box, everything seems to be fine and following lines appear to /var/log/messages:

But, when trying to mount, it hangs for a while and following lines appear to /var/log/messages:

Got it working! All I needed to do was to disable "Assing IRQ for USB" option in BIOS.
Thanks for your help! |
