Compact Flash Card Types

Compact Flash memory cards come in two sizes. The CF cards are referred to as Type I or Type II.

The only difference between the types is the thickness of the cards. The width and length of the cards are identical.

  • Type I - 3.3mm thick
  • Type II - 5mm thick

The Type II spec was thicker to allow Microdrives to be used in the Nikon D70S. A Microdrive was a small mechanical harddrive.

When CF memory cards were first introduced they had high prices and very limited capacities. Microdrives made it possible to get large amounts of storage.

Microdrives are no longer being produced. Because they were mechanical, they often failed. So you cannot find them used.

SD to Compact Flash card adapters also take advantage of Type II sized slots. There are adapters that will allow you to use SD or Micro SD cards in a Compact Flash slot.

Card Reader

UGreen Memory Card Reader

The UGREEN 4-in-1 card reader is what I use with my CF cards.

The UGREEN reader is USB 3.0 compatible. Transfer speeds over USB 3.0 will be faster than the Nikon D70S.

The reader can read the following memory card types:

  • CompactFlash Cards
  • SD, SDHC, & SDXC Cards
  • Memory Stick (MS), MS Pro, MS PRO-HG, & MS XC DUO
  • MicroSD, Micro SDHC, & Micro SDXC Cards

Avoiding Card Read Errors

A frequent problems with cameras that use Compact Flash memory cards are bent card slot pins. When a pin is bent, you could see a ‘unable to use card’ error message.

To avoid bent pins, don’t force a CF card into the Nikon D70S. The extra space for a Type II card allows a Compact Flash memory card to be aligned incorrectly.

If the compact flash card will not effortlessly slide into the camera slot, take it out and check the positioning of the card. Also, check to see if there is any damage to the card or slot.

If everything looks fine, carefully position the CF card and make another attempt.
