So I check, under Mac OS X, you may use
For exemple for an Opus: newfs_msdos -F32 -v "Cybook Opus" /dev/diskX where X is the number of the disk that correspond to your Cybook. |

Thanks, Godzil. I have filed that gem in Evernote so will be able to access it in the future!

Hello Everyone here...
Sorry may I ask for help? I've got a Cybook opus with exactly the same problem as described in this topic. Everytime I turn it on It asks me the selection of language. If I use Calibre after I can't see the books I've put into the opus with. If I put the books into an sd card It recognizes them as soon as possible... I've got only linux on my computer and I tried these commands: sudo umount /dev/sdb sudo mkfs.vfat -l /dev/sdb1 But the last command isn't recognized!? The answer is: mkfs.vfat 3.0.9 (31 Jan 2010) No device specified! Usage: mkdosfs [-a][-A][-c][-C][-v][-I][-l bad-block-file][-b backup-boot-sector] [-m boot-msg-file][-n volume-name][-i volume-id] [-s sectors-per-cluster][-S logical-sector-size][-f number-of-FATs] [-h hidden-sectors][-F fat-size][-r root-dir-entries][-R reserved-sectors] /dev/name [blocks] What can I do? Thanks in advance |

What IS*the version of your OPUS?
If it is not the latest version (2.1 / 1.6) do not bother to ask nor try to format it. (sorry to be aggressive about this, but there is a lot of people asking for support on device that have version that are buggy, and, it was well described, so I make no longer support for device that are not up to date, version prior to 2.1/1.6 have huge bug on internal FS support for both Gen3 400Mhz and Opus, and the only solution is to update the device to the latest version) Last edited by Godzil; 06-30-2011 at 04:17 AM. |

No problem. It is the last. I downloaded the 2.1 firmware and installed it. The reader acts exactly as described in this topic:
1) selection of language at turn on 2) calibre doesn't work 3) books on microsd are recognized. Ps: only I think I'm stupid using the terminal in linux because that damned "-l" isn't recognized! |

Strikeiron, maybe it's not enough just to install 2.1 firmware. Follow Godzil's whole advice, format your Opus and then install 2.1. You don't need to fear any disadvantages from doing so, it won't break your device.

Well thanks to another forum we solved it. The problem is thereis a partition table in the inner memory.
If in the terminal you write: $ cat /proc/partitions And the output shows sdb and sdb1 It means that there is a partition table, the solution is removing it by: sudo dd if=/dev/sdb of=/tmp/sdb.dump bs=1024k count=1024 and then formatting the sdb in fat32 with these commands: sudo mkfs.vfat -F32 -n "Cybook Opus" -s 8 /dev/sdb or if the output is: mkfs.vfat 3.0.9 (31 Jan 2010) mkfs.vfat: Device partition expected, not making filesystem on entire device '/dev/sdb' (use -I to override) then you add -I to the last: sudo mkfs.vfat -F32 -n "Cybook Opus" -s 8 -I /dev/sdb Following this the Opus works again. |

Thanks for your explanations, Strikeiron. Hope they will help others with the same problem. Enjoy your Opus! |

I am supposed to make a correction:
the command dd only read and copy a partition. The real solution is: sudo mkfs.vfat -F32 -n "Cybook Opus" -s 8 -I /dev/sdb -I is really important due to this fact: -I It is typical for fixed disk devices to be partitioned so, by default, you are not permitted to create a filesystem across the entire device. mkdosfs will complain and tell you that it refuses to work. This is different when using MO disks. One doesn't always need partitions on MO disks. The file system can go directly to the whole disk. Under other OSes this is known as the 'superfloppy' format. This switch will force mkdosfs to work properly. |

Hi, I've the same problem: the Opus doesn't see the books on the internal storage but only on microSD.
I formatted the internal storage with all kind of formatting indicated in this thread and in other threads: - using gParted; - with sudo mkfs.vfat -F32 -n "Cybook Opus" -s 8 -I /dev/sdb1 - simply with mkfs.vfat -l /dev/sdb1 - with Computer desktop icon --> Right click on Opus, Format in Windows XP. In all the above cases, i succeeded in formatting; then I start the Opus, it asks me the language and I can see the directory sBooks, Picture, etc in the device. But, when I see the internal storage with PC, it's empty, there aren't directories. I tried to create directories and load a book but Opus doesn't see it...it seems that the directories that the Opus shows doesn't match with the directories that I created and that I can see in PC's File Manager. I also installed the firmware afresh but the problem persist...what can I do?! Thanks a lot. |

When did you do that? This should be your next step immediately after formatting the device. And if really nothing helps: send the Opus back. Ask for a replacement or a refund, maybe there is something wrong with the hard disk of the Opus. And did you create a folder "ebooks" to store your books in? Welcome to Mobileread, themind24! |

I resolved the problem with these steps:
- delete table partition in internal storage: Code:
sudo dd if=/dev/zero of=/dev/sdb bs=512 count=1 - make new file system with: Code:
sudo mkfs.vfat -F32 -n "Cybook Opus" -s 8 -I /dev/sdb Thanks all! |

If you have "sdb1" it that because you make a partition table on the device, and it can't work. You have to use is as a whole device partition (ie on sdb) like sdcard, usbkey or floppy
