BMC 50 Max 3 w/386 motherboard

[jp41558]

We have a BMC 50 Max 3 with one of the first generation 386 motherboards. We have lost the hard drive on this machine twice now. The first time we replaced it, this time we just load the machine disks to bring up the machine but everything is lost once we power down. We worked with the service at Hurco and they had us try and reformat the hard drive and reload but it looks like we have a bad sector in on of the areas that is reserved for the Hurco operation system. I was thinking of buying another hard drive and trying it but know that I have to have the correct drive to get the system to recognize it. Any suggestions on how to figure out if I can match up a drive or how to get it to work on our system?

Most any drive will do. Smallest you can find around the 400mb mark for V1 software (the max the system can use so if you fit say, 2gb, the rest is wasted. Try and avoid Western Digittal. For V2 software, up to 2gb is ok.
Find an old PC and dig the drive out of it.
