Recover lost parition

How big is the Drive? How big is each Partition?

Want to make sure I understand this. Your C Drive with the OS and programs is 13.9 GB, D Drive is 19.0 GB, and you had an E Drive that was 2.27 GB that has disappeared. That would be a total of 35.17GB. Windows XP creates a hidden drive for your Restore files and this could be the 2.27GB that is missing. If this is a 40GB hard drive this would be about right, maybe a bit small, because Windows always reads a Drive as smaller than the mfg says it is, it's a mathematical thing. I think the mfg calculates susing omething like 1042 while Windows calculates it using 1000, I believe MB but someone else would have to give you a more precise answer. So if this is a 40GB drive and you have free space on D, you would have to reduce the size of D in order to expand C. I use a disk management program called Partition Magic that lets me do this kind of thing. I don't know how you can do this in Windows or if there are free programs that let you do this. Again, if this is a 40GB hard drive and D is full, then you'd either have to delete some of the stuff on D so you can make it small or get a second drive for storage and transfer everything from D to the new drive and then expand C. How much free space do you show on D? Is the drive 40GB or is it bigger than that?

it is the other way around. Windows (correctly) uses 1024 and the mfgs uses 1000 (so that the drive looks bigger than it is. Sneaky buggers.)

@OP

Do as g-paw suggested and use C and D
