Problem with Vulcan hard drive

[<telsasser@po-1.clinton.k12.ia.us>]

I have a 40 meg Vulcan hard drive on an apple IIgs.  About a year ago it 
started to freeze up for no reason, when I tried to reboot it would give 
me a message like "please insert the disk AE1"(AE1 is a partition on the 
hard drive).  I used the special feature in the partition manager ( the 
one where you type AE) to search for bad blocks but it would still 
freeze up after I was on the computer for a while.  I also tried to 
reformate it and repartition it.  The only way to it to boot was to shut 
it off for a few minutes and restart it but it will still freeze up 
after a while.  After a year it still does the same thing.  Does anyone 
know anything else I could do to try and fix it?

Thank You
