Hi Dannjohnson,

The below are the types of cards that your Hitachi Device works with :-

It's an all in one USB 2.0 Memory card reader , compatible with almost all types of usually used memory cards like :-

• SD card,
• CF Card,
• xD Card,
• Sony Memory Stick.

Your data would be read just like a floppy drive or another removable media , just plug in this card reader in your PC's USB slot and then you can use all the slots for memory card separately.
It will also have a separate drive letter for each slot for memory card that you see.

Hope this helps ...:) Your feed back would be appreciated.

the memory card chip might have been damaged..

you have two slots for memory cards .. one for XD and one for CF .. if you have trouble with one slot then you can try the other type card ..

if you are using a CF card or micro drive .. then look into the slot where they normally go .. look for bent or missing pins .. some CF memory cards don't have much of a "lead in taper" on their connector .. sometimes they will snag a pin and bend it, push it out of place or break it ... sometimes you can straighten it but replacing a broken pin is a big job .. usually the whole connector will be replaced if its sent in for repair .. if you have trouble with the CF slot you can instead use a XD memory card .. or visa versa .. the little LED flashlights are ideal for looking into the memory slot...
make sure you format any new memory cards in the camera before use .. that should pick up any problems and makes sure the card is compatable with the system ..

Those are card reader slots.

Various types of memory cards can be used.

A memory card, (Or can be stated as Flash Memory Card), takes the place of the old Floppy Disks, for one.

It is digital. There is no disk inside, just hardware electronic components.

Due to the size of trying to explain every type of memory card that is available, and the memory card itself, I would like to give you this link,

http://en.wikipedia.org/wiki/Memory_card

Here it explains the basic format of a memory card.
You can click on the titles of the memory card/s, (in blue), to get a deeper explanation, of that particular memory card.

The specifications for your eMachines ET1810 Desktop PC, state that you have the following card reader slots for,

1.Compact Flash (Type I and II)
2.CF Microdrive
3.MultiMedia Card (MMC)
4.MMCmobile
5.MMCmicro
6.Reduced-Size MultiMedia Card (RS-MMC)
7.Secure Digital Card (SD)
8.miniSD Card
9.xD-Picture Card
10.Memory Stick
11.Memory Stick PRO
12.Memory Stick PRO Duo
13.Memory Stick Micro (M2)

Look above each slot for an abbreviation.
For example on my computer,

I have one card reader slot that is approximately 1 inch wide.
It looks like a T that is stretched out.
It has SD/MMC/SM/MS/MS-PRO, above it.

This means that the card reader slot will support, (Use),
[In order as printed above],

1.SD Card - Secure Digital Card
2.MultiMedia Card.
3.Smart Media card
4.Memory Stick
5.Memory Stick Pro

I have one more card reader slot. It has CF-Microdrive above it. A wider slot than the above, and looks like a upside down stretched out T.

This means of course that it uses, (Supports), a Compact Flash Microdrive card

I've tried to explain the various card reader slots, on your computer's front panel, without being too technical, or being offensive in nature.

If you want, I can explain as technical as you wish, or simplify my solution more.

This is the Specifications page for your eMachines ET1810,

http://support.gateway.com/emachines/desktop/2009/emachines/et/et1810/ET1810sp2.shtml

Scroll down, and look to the right of the heading - Card Reader.
These are the cards your computer supports, (Uses)

Looking at the main support page for your eMachines, it looks as though you have four card reader slots.
Three grouped together on the left side, and two in the middle.

The two slots to the far right are USB ports, with probably a headphone jack port, and a microphone port to the right of them.

This page gives a little more detail, as to what your card reader slots support,

may be ur computer is not able to read the stick, try it on another PC, some times the memory stick has some power left in it when removing from the camera and the same has to be discharged, to do this refit the stick to you camera and access the stick, then shut down the camera by power off button of the camera and then remove the stick from the camera and connect it to the PC.

Have you tried using an SD card? The hx2000 is supposed to support SD cards and CompactFlash Type II memory cards. If it doesn't respond, it's possible that your second-hand device simply has a faulty card slot.

The camera body has a tiny switch marked "CF" in one position and Sony's "memory stick" symbol in the other. Apparently I accidentally reset the switch from "memory stick" to "CF" while slipping the camera body into (or out of) its carrying-case. Once I had set this switch from "CF" back to the "memory stick" position, everything worked fine. Solution:  read the user's manual more carefully next time!!

The only advice that I could offer is to try those 2 Compact Flash cards on someone elses PocketPC. If they don't work then there must be something wrong with the cards. However, if they both work then there must be a problem with the CF slot on your Jornada. Try to test out some CF cards from an electronic store if they will let you. Yes, you do not need drivers for CF cards. A preferred CF list? Whomever told you this is blowing you off. People use all brands of CF cards from Viking, Scandisk, Lexar, Mr. Flash, etc. Sometimes there is a bad card and other times the CF slot is bad so check both of those out...
