When I plug in my memory card, the drive isn't assigned a letter, etc. Thus I am not able to access it from My Computer. When I run a partition analysis program it picks up the drive, so I am sure that the card is working. What's the problem?

Does it show up in disk management? – Bali C Sep 26 '12 at 15:56

There's no problem. This is perfectly normal. For regular disk partitions, unless a filesystem is mounted and assigned a drive letter, it will not show up under My Computer. If you want to access a partition from My Computer, assign it a drive letter using the disk manager. (Type diskmgmt.msc into the Run bar.)

You may also have a broken filesystem on that partition. If assigning a drive letter yields a partition that shows as "RAW" or otherwise shows in My Computer but you still can't access it, try reformatting the partition. The usual warnings about lost data apply. – BowlesCR Jan 13 '14 at 18:27
