digi camera storage

Do digital cameras have any internal storage? Or is all data stored on the SD card?

If you hook up the camera to a PC via USB, remove the SD card - is there any data?

What is the file system used on SD card?

Also, many tools can recover data off "cameras", like deleted images, in such cases, is the recovery software recovering the data from the SD card, or from some internal memory?

If you have an orphaned SD card, how can you get the data off it? I..e how can you hook it to the PC to retrieve the photos if you dont have the camera?

Some cameras have permanent storage built in.  

The filesystem is readable by Windows if you connect it with a USB cable.  

If your camera doesn't have built-in storage and you remove the card, you won't see any file system for the camera device.  

You can use file recovery software like PC Inspector to recover deleted files.

Use a USB card reader to read camera SD cards - some machines have these included, especially laptops.

Your question is a bit broad or vague... are you asking about a particular camera or brand of camera, or were you really asking a very general question about ALL digital cameras?

Re: Internal storage: Yes, most if not all digital cameras have a limited amount of internal storage.  Some less expensive cameras don't even allow for external storage media.

Re: File system on an SD card: SD cards are usually shipped with FAT32

Re: Data recovery tools: Yes, these tools should be able to recover from either the camera's internal memory or the external memory, as long as either of them is accessible by the operating system of the computer it's connected to.

Re: "Orphaned" SD cards: There are several "memory card reader" devices on the market.  Most connect to a computer via USB, and they have slots for one or several various memory card types.  Laptops and even desktop computers sometimes have SD and other memory card slots built in.

Wikipedia has some good info on SD cards here:

There's also a very well-respected online publication about digital cameras here:

Hope this helps.

How does the user know where their image is going to be saved  if theres both internal storage and an SD card  (what kind of "internal drive" is this in a digi camera)? can you provide details? Do files get written to an SD card if the internal is full, or is the internal used if theres no SD inserted? What are the rules?

can you provide details on the type of hardware the internal storage is? and what is the file system it utilises? if sd is fat32 - what is this internal drive?

PMA111,

In Winodws, if you have a camera connected with both internal and external storage, they should each show up as different drive letters.  You will have to determine which is which on your own comparing size, pictures, folders, etc.  You could take the memory out and look at what's on any internal memory first, then try connecting with both internal and external to compare.  I have to do this with my smart phone, as it has both internal and external memory.

One additional note: Windows has a rather arbitrary way of assigning drive letters.  One time the internal memory could be F: and the external G:, while the next time they could be reversed, or even different drive letters if you've connected/disconnected another USB storage device.

Good luck.

Or, you could simply plus the SD card into a "reader" to avoid confusion.

Also, your pictures will likely be a folder called "DCIM" (Digital Camera IMages).

The internal drive is nothing more than a memory chip, like the SD card.  It uses the same formatting as the SD card, to simplify camera electronics.
