:pint: Welcome to Amiga.org, Ulver!
As Cyberus suggested, you may wish to back up all of the files that your hardware needs before formatting anything.
There is also a web site that may be of use to you. It contains legal archives of install software for obsolete Amiga hardware. The site is
here.
;-) The Amiga OS 3.1 as standard uses 32 bit addressing and so will be limited to hard drives of four binary Gigabytes, or 4.3 decimal gigabytes. Remembering that up front will save many headaches. To go beyond that will require OS 3.9, which I use, or an add-in module from Aminet. My signature links to them.
