Dangers in copying pics from camera to computer

wrote: In article , says... Any one who is even a little bit serious about photography would buy a card reader ... they ain't all that expensive! A statement that is not necessarily appropriate. My camera uses xD cards. My card reader has a dual slot for xD cards, and it's extremely difficult to actually push the tiny card into that huge slot and find the proper position. What's more, the card reader (HP) is actually A LOT slower reading info from the card than my camera (Oly 5050), despite the fact that it transmits data to the comp via ethernet rather than usb. The only time it makes even remotely sense for me to use the card reader is, if I want to do lengthy operations on the card: multipe copies, renaming as I go, rotation....(as discussed, to avoid draining the batteries in the camera with possible problems arising). As a day to day operation, rather than finding my reading glasses, and fumbling the card into the reader, then waiting 3 minutes for the reader to initialize all the pics on the card, I rather plug the usb cable into the camera, into the hub on my monitor and I am away in seconds, without messing with that tiny chip. I have used some of the larger card formats from other people's cameras in the reader and at least the fumbling part does not apply. Just as slow, though. -P. A better card reader will obviate your problems. -- Bill Funk replace "g" with "a" |

Dangers in copying pics from camera to computer
"Jim F B" wrote in message ... A friend has alerted me to the potential danger in copying your digital pictures directly from your camera to your computer. Apparently, if the camera battery goes flat while the transfer is taking place, it is possible to lose all your pictures. Worse still, there is the possibility of permanent damage to your memory stick. Of course, the way to overcome this risk, is to use a card reader to transfer your pics on to your computer. I was rather surprised to learn about this possibility because I have always transferred my pics to my computer directly from the camera. Can anyone advise me why memory sticks and SD cards are subject to failure in this manner? I would have thought that the manufacturers would have been able to build in safeguards so that this sort of thing could not happen! Has anyone experienced loss of pictures or damage to SD cards as a result of a flat camera battery during the transfer process? Do you think it is a wise safeguard to invest in a dedicated card reader? Thanks for your advice. Jim Of course you'll also notice that once you (not anyone else) remove your camera batteries everything on the memory card in the camera is deleted --- you'll believe anything. Downloading does not effect what's on the card at all. Pulling a memory card in and out the camera all the time is going to be real good on the wear tear of all contacts. If the low warning is showing for rechargeable batteries only a fool would **** round trying to download many pictures from a camera to a PC. E. Scrooge |

Otherwise, I would agree, that the downloading process does not alter what's on the card at all, it stays there until your format the card or erase the pictures (formatting being the preferred way to delete your pictures from a card to avoid build up of any remnants).

If the low warning is showing for rechargeable batteries only a fool would **** round trying to download many pictures from a camera to a PC. A good point about pulling memory cards in and out of the camera, but I guess they are fairly robust and that it would take a long time to wear down the contacts to any serious degree? After being warned, I will now at least check for flat batteries before doing a download, but I like the idea of leaving the card in the camera as much as possible. Regards, Jim |

Per (PeteCresswell):
I got a little USB2 plug-in reader for my CF cards at CompUSA. Nametag on mine says "Thunderbolt CF Card Reader". It's from www.ziocorp.com -- PeteCresswell |

"(PeteCresswell)" wrote in message ... Per Jim F B: Do you think it is a wise safeguard to invest in a dedicated card reader? Yes. Also because of: - The convenience/portability factor. Keep it in your bag and you can upload to somebody else's PC without installing anything. - No worries about installing dicey camera mfr software on your PC. I got a little USB2 plug-in reader for my CF cards at CompUSA. It's also extremely fast.. -- PeteCresswell do they export to nz? or, were you in the states? |

For 10 to 15 bucks getting rid of all the hassle of connecting your camera to the PC you mean? You bet. The hassle need not be very great. One of my cameras (Sony DSC-V1) acts as a USB mass storage device (aka card reader) so no software needs to be installed. The other (Canon 350D) acts as God knows what. Yes, you can use the memory card in most cameras as you would a hard drive, that is, you can record your word processing, spreadsheet, and any other files on it, but its capacity is rather limited (hard to get cards here greater than 4GB). A 60GB Ipod is a better supplementary drive to back up all your computer files on. How is what you just said relevant to copying photos from the flash card to the computer? -- Måns Rullgård |

If the OS updates access timestamps on the files as it reads them, it will be writing to directory entries in the card filesystem. Each flash page holds many directory entries, so if something goes wrong while updating a single entry, the entire page may be lost, and all the files with it. Recovery software may be able to retrieve the image data, but I wouldn't want to depend on it. -- Måns Rullgård |

So is it possible for data to be screwed up if the power goes off while a transfer of data is being made from a memory card that is in a USB card reader? Or are card readers protected against power failures so that the memory cards and their data are not harmed? |

Jim Why would you even try transfering pics when your camera batt is flat :-s Even starting with a full charge it may be impossible for me to transfer a GB of pics from my CF card to my computer. A USB dongle or a PCMCIA-CF card adapter for my laptop is the answer. About $15. -- a d y k e s @ p a n i x . c o m Don't blame me. I voted for Gore. |
