Has anyone tried to get the IBM drive (DCRA-22160) to > work in a 755? It has been my experience that various IBM drive models have different settings for the IDE master vs. slave jumper settings. I recently picked up an DSOA-21080 for my 760C which has this problem relative to to the stock 720Mb drive. What happens seems to be this: the Thinkpad (or docking station) in which the drive is installed is responsible for setting the master vs. slave ID of the drive. On Thinkpad drives, shorting the appropriate pin pair makes the drive a master. Unfortunately, on some of the IBM drives (including the DSOA-20180), it's the *absence* of the jumper that makes the unit a master -- the presence of the jumper makes the drive a slave. Now, what I've been doing so far is just using a bit of tape on the caddy connector to prevent the ThinkPad from erroneously jumpering the device to be a slave. Of course, this won't work if the drive is supposed to be a slave (presumably whenever the drive is in a docking station?) but it works for me right now, anyway. -- Tim Tyhurst tim@excelsior.com
