I have a Milltronics 1 ver2.25 controller that hangs at initializing front page. It has a Simdrive. I can get into the shell and when checking the SRAM it shows,

730112 bytes total diskspace
4096 bytes in 3 dir
45056 bytes in 36 user files
608256 in bad sectors
72704 bytes available on disk

My question is, is the card bad or can it be formatted to fix the bad sectors. I don't have any backup disk to reinstall the software unless it would be available online somewhere.
Would it be possible to install a hard drive if I could find the software? The motherboard in a 486.

Any comments would be greatly appreciated.
