Thanks for everyone's help so far. I finally managed to get back in the loft and dig out an old Workbench floppy. Unfortunately the WB3 disk didn't work but I managed to find a WB2 one that did and I was able to boot into Workbench without locking up. however, as soon as I tried to browse the contents of my hard drive, the stopwatch reappeared and was stuck busy again - it did show more contents than booting directly from the HD though.
Would this suggest that my hard drive is busted? Are there any tools or applications within WB that I can use to examine the drive or try to repair it? My Shell knowledge is very limited but I tried poking around with a few commands. Given that DF0: displayed the contents of my floppy drive, I tried to access CC0: but it kept returning the contents of my floppy drive. Is that normal, or does that suggest more issues with the HD?
Typing 'Info:' into shell shows a CC0: of 29k, 0 errs and a status of read/write. I'm pretty sure this drive was about 300MB
Despite my delayed response, I really appreciate the help you have provided so far - it's just hard to set aside time for personal projects with the kids off school!
Thanks,
Jim
