Secure Digital High Capacity (SDHC) memory cards refer to any SD cards that are 4GB or larger. The packaging on many SDHC cards only refers to them as SD cards, which could lead you to believe erroneously that they are compatible with your Toshiba laptop. If you have a newer model laptop, however, you likely already have SDHC compatibility. If you have an older model Toshiba, you may be able to correct the problem with a free software download.

Eject the card from your Toshiba laptop and inspect the metal connectors. If you see any dirt or debris, clean it off with a lint-free soft cloth. If you see rust or corrosion, the card may be beyond repair.
Insert the SDHC card into your Toshiba laptop's card reader, pressing it into place until you hear a click. If the card isn't recognised, eject it and reinsert it.
Check the user manual for your Toshiba laptop and find out if your card reader is compatible with SDHC cards. If it isn't, download the SDHC update from the Microsoft website (see Resources). Restart your computer once the update is complete and reinsert your card. If it still isn't working, move to step 4.
Insert the card into another computer's SDHC-compatible card reader. Click the Windows "Start" button and click "Computer." Look for your 8GB SDHC card under "Devices With Removable Storage." If it doesn't appear, the card has likely been corrupted beyond repair. If it does appear, right-click it and select "Format." Choose "FAT32" from the drop-down menu and click "Start." Wait for the formatting to complete, then click the "Safely Remove Hardware" icon in the desktop taskbar. Choose your SDHC card and click "Stop," then eject the card when prompted. Insert the card into your Toshiba laptop's card reader and look for it under "Devices With Removable Storage."
