First step is relax. Deep breaths, in and out. Goosefraba.

Second, we need some basics. Speccy is a freeware tool that can be downloaded and used to generate a wealth of system info. Export this information to a text file, and copy the results here.

For now, let's go to your computer. Right click on the flash drive, select properties.

Please reply with:
General tab - file system, used space, free space

Next, go to the "Tools" tab. Click "Check now" and confirm when the UAC box pops up.
Make sure only the first box (find and fix file system errors) is checked.

Ok I'm kind of relaxed.

I am on the General Tab. The File System is "FAT". My used space is 0 bytes. My free space is 1,073,446,912 and right beside it, it says .99 GB. After checking that i went to tools like you said to do and checked for any errors. None were found. I don't know what to do now!

Right click the drive again, but this time click "Format". Select the default capacity, select NTFS file system, 4096 byte allocation unit size, name it anything you like, and tick the "Quick Format" box.

After you have done all this click "Start" and confirm any message boxes that show up.

Ok the Format is complete and now it says that 989 MB free of .99 GB. Now when you said to select the default capacity, all it said is 1.00 GB so I selected that

Just about a year old. I'm guessing that there is nothing that can be done, correct?

Hi

What were you using it for between the time it last said it was 8GB and the time it first said it was 1GB?

Specifically, I'm wondering if you used it for a phone or tablet.

No, I wasn't using it for anything. I haven't used this for a month but a month ago I did install a bootable version of Ubuntu on it. But then I deleted it and it was all fine. I never used it for any phone or tablet

If the capacity was correct after removing Ubuntu then I would consider it to have gone bad and would not trust it anymore.

What I was looking for was a situation where some partitions were placed on it that can not be seen properly by Windows (this often happens with certain Linux partitions). I usually see this when the card is used for loading custom ROMs on a phone or tablet.

James makes a good point, Linux partitions can use a different file system that Windows doesn't account for at all.

However, a format of the drive should completely erase all data (including existing file systems) and in this case have established the new NTFS partition.

I would say at this point to replace the flash drive. They are dirt cheap now and not worth your time when it comes to trying to troubleshoot an oddball error without any critical data on board.

Ok well thanks for the help anyway. I have a USB 3.0 port on my laptop but should I invest more money into a USB 3.0 or just get a USB 2.0 USB Drive. And will the USB 3.0 flash drive work in the USB 2.0 port. Also what is the highest size USB 3.0 or 2.0 port you can get

A USB 2.0 drive will work in a USB 3.0 port, but not vice versa.

It depends what you use it for. If you routinely move large numbers of large files, you may benefit from a USB 3.0 drive, however most of the time USB 2.0 will be sufficient (I don't even have a USB 3.0 flash drive). I would recommend a USB 3.0 external hard drive though, the speed benefit there is substantial.

As far as sizes, they are available up to 128GB currently. Those are a bit expensive, so I would recommend something in the 8-64GB range. The 8GB drives can typically be had for $10 or less, and there are 64GB drives available for under $50.
