According to a post on Reddit, the free space available on the E drive (partition 1) of an original Xbox after modding is approximately 50,000 blocks 1. One block is equivalent to 16 kilobytes 1.
If we assume that the Xbox’s hard drive has a capacity of 8 gigabytes 1, then the total number of blocks on the hard drive would be approximately 524,288 blocks. Therefore, the 50,000+ blocks available on the E drive would represent approximately 9.5% of the total blocks on the hard drive.
Please note that the above information is based on a post on Reddit and may not be accurate. It is also important to note that modding an Xbox may void its warranty and is not recommended by Microsoft 1.

I did some research from my calculator and found out you (could) have 500,000 blocks on an 8GB harddrive
