Replaced Master HD, but OS does not see Slave

[ctyankeeinok]

FACTS: OLD PC - Micron MMX 166 with Pheonix m55Hi BIOS (purchased 05/97)
Had Maxtor 40GB as master, runs EZ BIOS on boot. Old original HD (WD Cavier 2.5 GB) as slave. Worked fine for 2+yrs. Alas, Maxtor was failing - suspect a recent brownout/blackout.
Replaced Maxtor with used Seagate 6 GB. Seagate was FDISK'd and formatted prior to install, so I installed and did a SYS C:. Left WD as slave. Seagate works fine, but the slave is not recognized. Seagate is plugged into cable as master, WD plugged into slave. Tried jumpers set to master (Seagate) and slave (WD), just like the prior setup, but Win98 does not recognize. BIOS does see the slave and shows proper cyl/head/sector settings. Cable select would not work (did not see Seagate at all). Removed Seagate, reinstalled Maxtor with WD as slave, and the slave appears in the OS just like old times. Is there something with EZ BIOS that made the old config work? Do I need to load EZ BIOS (or something else) on the Seagate?

BTW, if I put the Maxtor as a slave with slave jumpers and Seagate as master, WIN98 does not see the Maxtor. Seagate is ATA 66. WD is not. Using 80 wire cable.

How/when did you partition the 2.5GB drive? (eg, did you just leave it as was, did you wipe it and create new partition - if so was it promary or extended. If extended, that might be problem - it needs the primary partition - 40GB drive in place). EZ Bios causes problems when trying to access drives elsewhere - but if only 40 GB driver partitioned using EXZ Bios....)

I woudn't bother with all this - you can access 2.5 GB drive with 40GB drive in place. Back it up (assuming you have CD writer or similar), repartition/format it & replace data. If no backup - put all 3 drives in place at once, and copy 2.5 to 6?

I left the 2.5 as it was when it came with the PC. I just moved it from the master to the slave position 2 yrs ago when I installed the 40 GB. I used Maxblaster/EZ Bios to set up the 40 GB and copy the data from the 2.5 GB to the 40 GB. Your last suggestion is somewhat what I ended up doing. I reinstalled the 40 and 2.5 and hooked up a laptop to the router and copied the critical files (at least what I thought was critical at the time! - you know how that goes...). Then I reinstalled the 6 GB and copied the files back from the laptop. Much faster than writing CD's (other than the swapping hard drives, but I'm pretty quick at that now!).

My orginal intent was to keep the 2.5 as is on standby for retrieving files and backing up files, but it looks like the former intent won't work. Thanks for your help and ideas.
