List of common types of memory cards:
- CompactFlash I
- CompactFlash II
- IBM Microdrive
- Secure Digital (SD)
- Memory Stick
- Memory Stick Pro
- Memory Stick Duo
- Memory Stick Pro Duo
For memory card specifications, see the HP support document, General Information About Memory Cards .
Using a card reader
Choose a topic and click the heading or the accompanying plus (+) sign to expand the information.
CAUTION:Do not insert or remove memory cards while the light on the reader is flashing. Doing so may cause loss of data on the card or may permanently damage the card reader.
The following steps explain how to use memory cards in a card reader:
- Insert a memory card.An autoplay window appears. If not, access the card through Windows Explorer.
- The memory card has a drive letter associated with it, just like a CD-ROM drive, or hard drive. Use the memory card as you would use any other drive on the computer. For example, double-click the memory card icon to open a new window showing the files on the memory card.
- When you have finished working with the files on a memory card, us the Safely Remove Hardware
feature to remove the memory card. This feature appears as an icon in the taskbar. Safely Remove Hardware feature in taskbarSafely remove hardware feature in taskbarClick the Safley Remove Hardware icon and select Eject or Safely Remove to remove the memory card.On some computers, you can use the eject feature in the Computer window to eject or safely remove the memory card.Open the Computer window, right-click the memory card icon, and select Eject or Safely Remove .Figure 3: Eject feature in the computer windowAn alternative to using the Safely Remove Hardware feature is to use the Optimize for Quick Removal feature in Windows as follows:Click Start , enter device Manager in the search field, and then select Device Manager from the list. Click Continue if a UAC message opens.In the Device Manager window, double-click to expand the Disk drives list. Memory card readers are seen as drive devices in Windows.In the list of drive devices, right-click the device to display a drop-down menu (for example, Generic USB CF Reader for Compact Flash media). Click Properties in this menu.Click the Policies tab in the Device Properties window.Select Optimize for quick removal , then click the OK button.This setting disables write caching on the device and in Windows, so the media can be removed without using the Safely Remove Hardware feature in the taskbar. A disadvantage of doing this may be a minor drop in device performance.
Before storing anything on the card for the first time, format the memory card from your digital camera or by using the following steps:
Show me how
- Insert the memory card into the memory card slot. If an autoplay window opens, close it.
- Click Start , and then click Computer .
- Under Removable Storage, right-click the memory card icon representing the card type inserted.
- Select Format .
- Enter a Volume label name into the label field. This is the name that will appear next to the drive letter in Windows.
- Click Start .
- Click OK on the Format Complete window.
- Click Close to finish.
Resolving issues with memory cards
Choose a topic and click the heading or the accompanying plus (+) sign to expand the information.
Inserting a high capacity SDHC card into an incompatible memory card reader might cause the card to stop responding or lock up the computer window. To immediately fix the lock up, double-click the Safely Remove Hardware icon, (in the notification area in the lower right corner of the screen), select the USB card reader, and then click Eject , or Safely remove . The card reader may not work until the computer is restarted. You can now safely remove the memory card and use the computer for other activities.
To use your higher capacity memory card without locking up the computer, do one of the following:
- If you are using the card in a camera or other device, attach the device to the computer using a USB or FireWire cable. When connected, most devices appear in Windows as a Removable Disk and can be used in the same way as the card reader.
Make sure the card reader specifically supports the SDXC format. You can access the SDXC card by using an SDXC compatible USB reader or adapter. Look for an SDXC logo on the device or check with the device manufacturer for information.
CAUTION:Never format an SDXC memory card in a non-compatible device. Doing so will make the memory card incompatible with SDXC devices because it will erase the data on the SDXC memory card and format the card for a different file system.
If you cannot access the memory card, or the drive is not listed in the Computer window, use the following steps until the drive displays:
NOTE:If no card is in the reader, Windows 7 does not list the drive in the Computer window.
NOTE:If you are using a card reader that did not come with the computer, contact the manufacturer of the adapter for help.
- Remove and reinsert the memory card.If the AutoPlay window opens or if the memory card is now listed in the Computer window, you are done. Otherwise, continue with the next step.
- Restart the computer.If the AutoPlay window opens or if the memory card is now listed in the Computer window, you are done. Otherwise, continue with the next step.
- Reinstall each memory card device using Device Manager:
- Remove all memory cards, and unplug all USB storage devices from the USB ports.NOTE:Make sure you remove all USB devices.
- Click Start , type Device Manager into the Search box, and press Enter . Click Device Manager in the search results.
- Click the plus sign next to Disk Drives to open the category.
- Right-click a Generic card reader device name and select Uninstall .
- Wait until Device Manager updates the list, removing the name of the Generic device.
- Continue uninstalling Generic card reader device names until they are all removed from the list.
- Restart the computer and use the card reader. If problems persist, continue to the next step.
- Try another memory card of the same type in the same slot. If this memory card works, the card reader is working correctly. Replace the original memory card. If the second memory card does not work, continue using these steps.
- Turn off the computer, disconnect the power cord, and press the Power button on the front of the computer for five seconds. Reconnect the power cord and turn on the computer to test the card reader.If the AutoPlay window opens or if the memory card is now listed in the Computer window, you are done. Otherwise, continue with the next step.
- Some memory card readers also support USB devices. Insert a USB device into an open USB port to test whether the card reader can read from the USB device. If the device works correctly, continue to the next step. If the USB device also fails, there is a problem with USB. See the HP support document, Troubleshooting USB Connections in Windows 7 , for further troubleshooting.
- Turn off the computer and disconnect the power cord. Then shine a flashlight into the empty card slots in the card reader to see if any pins inside are bent. Straighten any bent pins with the end of a mechanical pencil. Replace the memory card reader or have the computer serviced if a pin is bent and is touching another pin.If the AutoPlay window opens or if the memory card is now listed in the Computer window, you are done. If there were no bent pins, continue to the next step.
- Reset the cable connections and memory card firmware using the following steps:
- Remove the side of the computer case by unscrewing the two retaining screws on the back of the computer and sliding the side panel towards the rear of the computer. Set the panel aside.WARNING: The edges of metal panels can cut skin. Be careful not to slide skin along any edge of the computer's interior metal.CAUTION:Electrostatic Discharge (ESD) is the release of static electricity. ESD can damage components inside the computer. To reduce the chance of ESD damage wear an ESD grounding strap and work on the computer over a hard, non-carpeted surface.
- Find and disconnect the cable from the back of the card reader and leave it disconnected.
- Make sure that the other end of the cable is correctly connected to the motherboard or to an electronic card connected to the motherboard. Make sure that the unconnected end of the cable is not touching any electronics or components inside the computer, particularly the fans.
- Replace the computer side panel and turn on the computer.
- After Windows starts and the desktop displays, wait about five minutes for Windows to make the necessary hardware changes.
- Turn off the computer and remove the computer side panel.
- Reconnect the cable into the back of the card reader, replace the side panel, and turn on the computer.
- Check to see if the drives appear in the Computer window or Windows Explorer:
- If the memory card drives appear in Windows and work correctly, you are done.
- If the memory card drives do not appear in Windows, the drive might need to be serviced or replaced.
If you are having problems reading and writing data to memory cards, use the following troubleshooting tips:
- Try a different memory card of the same type in the same slot. If this memory card works, the card reader is working correctly. Replace the original memory card.
- Some cards have a read/write security switch on the card. Make sure the switch is set to Write Enabled before trying to write data to it.
- Make sure that the amount of data you tried to store has not exceeded the capacity of the card.
- Inspect the ends of the memory cards for dirt or material closing a hole or spoiling a metal contact. Clean the contacts with a lint-free cloth and small amounts of isopropyl alcohol. Replace the memory card if necessary.
- Make sure the memory card is supported by the card reader.
- Make sure the memory card is fully inserted into the slot.
- Remove the memory card when the light is not flashing and shine a light into the empty slot to see if any small pins inside are bent. If the pins are slightly bent, turn off the computer and straighten them with the tip of a mechanical pencil. If two of the pins are touching, replace the memory card reader or have the computer serviced.
- If errors continue, replace the memory card.
Card reader drivers can become corrupted or stop functioning correctly, and new drivers and firmware are occasionally released to address issues. New firmware for your memory card reader might be available that could resolve the particular issue you are having.
To be sure you are using the latest driver and firmware, periodically check for new releases of this software on the HP Software Download Web page (in English). Type your product name on the Web page to view a list of available software for your product.
NOTE:If you are using an adapter for a type of memory card not supported by the reader and the memory card does not work, contact the manufacturer of the adapter for support.
