Depends how you formatted them. Windows doesn't recognize drives formatted as "Mac Extended" (also known as HFS+, which is the default Mac drive format). If you want a drive which both Mac and Windows can read and write to, the safest bet is still FAT32 - Disk Utility will show this option as "MS DOS format". It's usually a good format for flash drives anyway, unless you need to boot a Mac from them (in which case, you must use HFS+).
So whenever I want to format a flash drive I choose MS DOS format??
If you want to be able to use it in Windows, yes.
What about my current drives? can't I change their format? or should I first transfer everything on my mac or to another external drive then erase with MS DOS format then get them back on it??
Reformatting them will wipe all data, so yes, you should transfer the files, reformat, then transfer back.
If you have a Windows machine that frequently needs to access data from a Mac drive, you should look at the MacDrive software. Note also that network file-sharing does not care about drive format, so you could possibly transfer files that way if need be.
