| 314996 | 2005-01-18 02:42:00 | That looks as if it's being recognised as a "camera or scanner" TWAIN device, not a removable disk. ;-) That probably depends on the way the camera works. Some appear as a disk, some don't. In general you don't format scanners. :o Some cameras can be used as big floppies for moving files. Does this happen consistently with this card? Or has it happened only twice, both times when this card happened to be the one in use? ;) Low battery might be the culprit ... My CFs have been formatted a few times on various computers (one has even been partitioned, and one partition made ext2 for Linux :D) and the camera still works. ;) I think FAT32 would be used by most cameras ... and any files or directories the camera needs are automatically restored by the camera the first time the card is used. After all, they have to allow for people putting in new cards. |

| 314997 | 2005-01-18 02:57:00 | Umm. It is happening more than once. Read the damn thread, G. :D Does it happen for the first picture of a sequence of pictures, or only the first picture put on the card? If you come back a few days later and take more (without removing any) is the first picture corrupted? A thought occurs ... can you change the properties of files on the CF? What would happen if you make the (corrupt) picture file readonly (so it can't be removed)? Will that get around the problem? Not as good as a cure, but life is short. |

After all, they have to allow for people putting in new cards . I'd check first, may be only last 2 years or so . Canon consumer range cameras with the "Digic" chipset can read FAT32 . Earlier than that would be limited to FAT16 . The Olympus cameras using Smartmedia have some panorama mode info on Olympus branded SM . If you wipe that the camera can't replace it, you have to find a card reader and some software to do it . |

| 314999 | 2005-01-18 03:14:00 | or only the first picture put on the card? If you come back a few days later and take more (without removing any) is the first picture corrupted? It happens only on the first picture put on the card. I can remove the card, remove the battery, then come back a few days later and only the first picture on the card is (still) corrupted, none of the others. A thought occurs ... can you change the properties of files on the CF? No, I am unable to change the file properties at all. Not as good as a cure, but life is short. This card's life is definitely going to be a very short one if it starts corrupting any of the other pictures taken! :D |

| 315000 | 2005-01-18 03:41:00 | Obviously your one is damaged either physically, or the file system on it. I'd suggest replacing it, they're as cheap as chips now anyway: www.flashcards.co.nz - v. cheap, v.fast. |

| 315001 | 2005-01-19 03:28:00 | Try renaming the bad file to "KEEPME" and see if that helps (of course if you remember to do what it says). If that directory entry, and the area of the card are in use, other files can't be fouled up in that exact place. ;) | Graham L (2) | ||
| 315002 | 2005-01-19 09:26:00 | That's the odd thing, unlike conventional hard drives, flash medias have controllers that rotate the blocks of storage to even out usage. The 1st picture after each format/complete erase will be in a new physical location each time unless you exactly filled the card before starting again. | PaulD (232) | ||
