Hard drive space requirement

ajordanajordan Member Posts: 3
eth-start.bat is using more than 30GB of my C drive.

This is a problem since I have a small SSD as my C drive which is mostly for WIn 8.1. I use a 2TB mechanical drive for most things.

Why is so much space required and how can I mine totally on my other drive?

Thank you

    It creates a dag file on start, if needed.
    You can delete the old ones.
    In linux, they are located in $HOME/.ethash and have name like full-R23*.
    I normally delete all the old dag files on restart/reboot.
    One file is around 1 GB in size.

    Thank you for the post.

    The dag does not seem to be the problem. I have 2 folders with thousands of "Microsoft Serialized Certificate Store". These folders are each 10+GB between the two of them.

    Is there a way to reduce the space needed for mining ether?

    Not sure if this helps, but you can always override the location where geth puts all its data.

    So, if your d: drive is the larger one, you could create a d:\Ether\data folder structurem and then invoke geth like this:

    geth --datadir "d:\Ether\data"
