Question about Canon PowerShot A50 Digital Camera
I've been using the Canon PowerShot A50 with no problems for the past 3 years and up til now have had no problem with the CF card (48MB) and the multimedia card reader. Just yesterday however, my computer (Sony VAIO PCG-V505EX) would not recognize the CF card, even thought it recognizes the reader. When I click on 'removable drive' under My Computer, a message comes up -- "please insert disc into drive H." (or drive G). The CF card was already in the reader. So I pulled out the CF card and re-inserted it into the reader. I got the same message. I rebooted several times, pulled the battery out of my computer, did all the things I could think of to fix the problem, alas nothing. I took my computer to a PC tech for a PC-tuneup, thought that would fix things. After the tune-up, I still had the same problem. The PC tech took the card reader and tried it with another computer to see if the problem was with the card reader. The card reader was fine. He suspected it might be the CF card itself. So I bought a new Lexmark 1G CF card and put it in the camera. I took some photos and the camera seemed to work fine as usual. I popped the card out of the camera. Plugged the CF card reader into my computer, then inserted the CF card. When I went into My Computer and clicked on 'removable drive H (or G, I got the same message. "Please insert disc into drive H." I thought perhaps the card reader had some bent pinholes, so I tried the Dazzle PCMCIA card reader with the new Lexmark CF card. Same message. I did some troubleshooting. I went into device manager to see if there was a problem with the USB connection, but couldn't find anything amiss. I checked the camera. It seems fine. I read the Canon manual and found a section about the CF card. It's possible that the CF card became damaged for some reason, atho I can't think of anything I've done that would have caused it to malfunction. The manual recommends reformatting the CF card or replacing the Windows driver with Sandisk ATA driver. I cannot for the life of me find the 'Format' function in the camera. I put the dial under "Play" and pressed the menu button, but kept getting the 'busy' message on the LCD screen and the 'P6'error message on the readout screen on top of the camera. The manual is really confusing. I haven't tried the driver replacement because I'm scared to mess things up even more. At this point, I feel the problem is one of 3 things: there's something wrong with the USB port or the driver software that controls it in my computer OR the CF card OR the camera. I asked the PC tech about the USB issue and whether I could download and reinstall the USB driver. He said the USB drivers are part of Windows Service Pack 2, so there wouldn't be anything I could download. I don't know where to go from here. It seems I've encountered something similar to this before, where the computer doesn't recognize that a disc is already in a particular drive and asks the user to "please insert disc into (whatever) drive." (This was with a CD not a CF card or a PCMCIA card). Do you have a simple fix, or suggestions for things I could try? I'm afraid to do a recovery because I fear I would lose my Microsoft Office software which I got from my last job. And I'm not sure this merits a recovery operation.
It isn't clear from your description, but are you inserting the reader into your USB port, and *then* inserting the CF into the reader? If so, try reversing this -- insert the CF into the reader, then insert the reader (with the CF) into a USB port. It is possible that your PC is only looking at the reader once (when it is inserted) and not finding a CF, then ignoring the CF once you insert it. If your camera can read and write to the CF, then it is unlikely that the CF is damaged. Since you have determined that the reader is ok, and since your PC recognises the reader, it is unlikely that it is a USB driver problem. Similarly, it is unlikely that it is a physical problem with the USB port, or the pins in the reader or the CF card.
