Harddisk checksum error/0K free error solving

[djkoelkast]

Something went wrong so the Amiga rebooted, but now I get checksum errors and there's 0K free on the disk, however there was over 800MB free on this 1GB partition.

I run OS 3.9 with BB1/BB2/Euro update

How can I fix this so it gives the actual free space left and stop giving errors.

I can't boot fully as some things crash, boot with no startup-sequence however does work.

The harddisk itself is 80GB but I only used 998 MB for the first partition, starting at the beginning of the harddisk. I have made no other partitions so far.

I'll try good old DiskSalv, I thought this was only for floppy disks ;-)

Took a while but it did the trick brilliantly, thanks!
