It works for a few minutes then gets Sector not found, drive not ready, ..., etc. I went out and bought a new one. It's from CompuAdd, but it's a WD1006V-MM2 (Western Digital). Now, theoretically, all I should have had to do was pop in the new one and all would work fine. I know the cables are correct, the setup is correct for the pc (cmos), except the drive always boots up with that high pitched buzzing noise that lasts for about 2 seconds and repeats about 20 times and the gets a Drive error. I've tried just about everything but to no avail. What could be the problem? The old MFM is one of the older full-length models. When I plop it back in, the hard disk boots up fine again (at least for a couple of minutes until it gets flakey again). PLEASE HELP!!! Could there be some special switches to set or something? I also noticed that it seemed like Disk Master was able to access the drive and was willing to do an init on it, but I have it filled with data and I'm not going to reinitialize the drive. But is it possible that I may have to. Could it be some MFM controller discrepency that requires that I reinit the hard disk because timing is slightly different or something? Thanks for any help...
