What are the capacities of the SD cards that won't read properly ?

What are you plugging the memory cards into ?

Is (are) the memory card slot(s) built into the computer ?
If so, what is the make and model of the computer ?

Are you using an external memory card reader that plugs into a USB port ?
If so, what is the make and model of the reader ?

Older memory card readers cannot read newer memory cards of over a certain capacity. In that case you get no response at all from the operating system when you plug the card in. If you have SD cards with a smaller capacity that read fine in the same reader, that may be what your problem is.
If that's what your problem is, you need to buy a newer card reader that can read higher capacity SD cards.

Windows assigns a drive letter to the memory card reader's slot, not the memory card itself, even when there is no memory card plugged into that slot that the card reader recognizes. If the same card reader slot supports recognizing more than one type of memory card, there is more than one drive letter for the same slot. There being drive letters for the card reader's slots doesn't necessary indicate Windows recognizes the memory card when one is plugged in.

If Windows DOES recognize a memory card when it's plugged in, if the memory card has a volume label, Windows will display that volume label beside the drive letter for the card reader slot. E.g. SD cards that had pictures recorded on them in my Canon cameras display Canon something .
.......

If the same SD cards that will not read properly in Computer or Windows Explorer now were showing they had space on them or data on that space previously when they were plugged into the same card slot built into the computer, or when they were plugged into the same slot in the external card reader was plugged into the same USB port, then the most likely thing is....

your problem was probably caused by you NOT clicking on the Safely Remove Hardware icon in your Taskbar and STOPping accessing the memory card slot's drive letter BEFORE you unplugged the memory card while Windows was running.
There are several programs that you could try that will probably fix your problem.

You posted response 2 and 3 before I had finished editing response 1.
Read response 1 again.

If you're sure the same cards read properly in the card reader previously that I assume is built into the Dell 573S, then see the last part of response 1 - that's probably what your problem is.

If the two cards also DO NOT read properly in the laptop NOW, then the data on the cards is probably damaged. See info about the programs that can fix that at the first link.

If the two cards DO read in the laptop NOW, then you probably have a problem related to the info at the second link .

What operating system is on the Dell 573S ?

"if i go into disk management i can see that it is plugged in."

If Disk Management shows there is NO DATA for the card reader drive letter, then you are NOT seeing the memory card there, you are only seeing that there is a drive letter assigned to the card reader slot.
The same applies to the drive letter assigned to a floppy drive or CD or DVD drive when there is no disk in the drive (or no disk that Windows recognizes).

If the space in the box beside the drive letter for the card slot shows RAW or Unallocated, Windows is seeing there is memory card in that card reader slot but it is not recgnizing the data on it properly.

Side notes....
You can certainly have problems with Autorun (auto play) working properly, especially in XP, but in that case if nothing else is wrong you can still see and access the data on the card in My Computer (or Computer in Vista or Windows 7) or Windows Explorer.

Apparently Autorun has been disabled on most people's Windows 7 systems, probably via a Windows update installed by Automatic Update, due to a problem with malware using it.

I have edited response 4.
Read it again.

"my OS is Vista and my card reader is built in to my CPU."

On both the laptop and the Dell 573S ?

"....and my card reader is built in to my CPU"

On the Dell 573S ?

The term CPU is often mis-used.
The desktop computer case that most of your hardware components are in IS NOT A CPU ! It's just a computer case, or a case.

The CPU - Central Processing Unit - is the microprocessor, a.k.a. processor, that's on the motherboard inside the case. It's the most complicated integrated chip on the mboard, it's usually the largest integrated chip and, and it's usually installed in a socket so that it can be removed, or replaced with a different cpu.

"when i go into computer it shows that there is nothing in my F drive (sd slot)."

The drive letter is assigned to the card reader's slot, not the memory card.

"If the space in the box beside the drive letter for the card slot shows RAW or Unallocated, Windows is seeing there is memory card in that card reader slot but it is not recgnizing the data on it properly."

It does say RAW and i can also see how much memory is used and how much is availible. So i guess it's not recgnizing the data on it properly, How do I fix that?

I probably did forget to eject or remove safely. I did that on my external HD a month ago and had to re-format the whole thing, I digress. I am running vista on both my laptop and my dell and they both have their own built-in sd card readers. your link directed me to another part of this site and i found these
links which one will fix my problem?

Go to Device Manager and see if anything listed is flagged as having a problem - a red X or a yellow ? .
If it is, RIGHT click on it, choose Uninstall,
if there is more than one choose Uninstall for each one,
then choose OK at the bottom of the Device Manager window, then Restart the computer, and that will probably fix the problem.

(e.g. RIGHT click on My Computer, choose Properties - Hardware tab - Device Manager tab.)

Look in Device Manager again.
If nothing is flagged, you're done.

If something has a red X, double click on it to see what the problem is.If it's Disabled try Enabling it.

My USB ports are all working again, But my SD reader is still not recognizing my SD cards.

In "Disk Management" It shows (SD Card) Disc 1 Removable 1.87 Online (F:/) 1.87 GB RAW Healthy (Primary Partition)

BUT in "Computer" or "My Computer" It doesnt show that anything is in F:/ drive. If I right click on F:/ drive IN both "Disk Management" and "My Computer" and click open or explore it says insert disk into F:/

And I tried downloading Glary Undelete, PC Inspector and Zero assumption Recovery
and I couldnt get any of them to help with this problem. I'm Not familar with any of these programs so maybe i wasnt doing something right but none of them worked.

Thank You For your Help and Patience Thus Far, its greatly appreciated

{Update}

So I found the CD that came with my computer labeled "Drivers and Utilities" and reinstalled my card reader back to factory and still same Problem Persists. PLEASE HELP ME

"In "Disk Management" It shows (SD Card) Disc 1 Removable 1.87 Online (F:/) 1.87 GB RAW Healthy (Primary Partition)"

That indicates Windows is seeing there is a ~ 2gb manufacturer's size SD card in the slot (1.87gb is it's binary size - the same total number of bytes - the mboard's bios and Windows, or any operating system, always see a drive's total data space, or a drive partition's data space, as it's binary size), but when it detects it's partition data space or the entire data space as RAW it's not seeing that it has data on it. That's caused by there being damaged (corrupted) data on the SD card - the data that indicates to Windows that the partition is using, probably, the FAT32 partition type for a 2gb card and that it is formatted is corrupted.
Windows IS seeing it has a Primary partition, so that part of the data is okay
The RAW partition type is what Windows shows in Disk Management when there is no data or partition type that Windows recognizes (on the device that data can be stored on), or in the case of a memory card or flash drive or external drive when Windows "thinks" there is no data because data on the drive indicating that is corrupted.
Similarly, when you install a new internal hard drive, it has no data on it, it's data space is shown as RAW, until you make at least one FAT32 or NTFS partition on it and format it in Disk Management.

"BUT in "Computer" or "My Computer" It doesn't show that anything is in F:/ drive. If I right click on F:/ drive IN both "Disk Management" and "My Computer" and click open or explore it says insert disk into F:/'"

When Windows detects the partition type as RAW in Disk Management, the partition contents cannot show up in Computer, or My Computer, or Windows Explorer.
In the case of a memory card, it's the drive letter of the card reader's slot, not the card itself, that shows up in Computer, or My Computer, or Windows Explorer.
Similarly, for a floppy drive or a CD or DVD drive, it's the drive letter of the drive, not the disk in the drive, that shows up in Computer, or My Computer, or Windows Explorer.
In the case of a partition on a hard drive, or a partition on a flash drive, no drive letter at all shows up for it in Computer, or My Computer, or Windows Explorer, if Disk Management is detecting the partition or the data space on the hard drive as RAW.

Regarding the data repair programs in response 9, I have not used any of them myself - they were recommended by others who answered on this site. Testdisk may be the best free one of the four. There are other ones as well. Read their Help info once you have loaded them. Some programs may also have Help or t-shooting info on the parent web site of the program.
If you were to send a PM (Personal Message) to OtheHill on this site, who is a forum moderator, he probably has other ones he can suggest you try and going by what he has mentioned I believe he may have had experience with using at least Testdisk.

There are many free or paid "undelete" programs out there, but many of them cannot repair corrupted data that indicates to Windows that there is a partition type on the memory card (or flash drive, or external hard drive) that Windows recognizes and that the partition is formatted.

Since you seem to be having other problems in Windows on the Dell 573S, you may be able to more easily fix the problem with the two SD cards by using a repair program on the laptop with them.
........

Part of the problem is Windows allows you to re-format a partition on a removable drive - on a memory card or a flash drive, but it does not allow you to delete the partition and make a new one. If the data that informs Windows that the card or the flash drive has a partition that Windows recognizes on it is corrupted, then you can't re-format the drive partition even if you don't care whether you will delete whatever data that can be recovered from it - you have to use a third party program to do that (unless you do something to Windows that allows you to NOT treat a partition on a removable drive as one on a removable drive , which is NOT recommended).

You CAN delete a partition on an external hard drive and make anew one, but that's of no help if you have data that you know is on it that you want to recover.
