Help! I have an IBM/XT with a 20 Meg Tulin and I want to add a 30 Meg Seagate Full Height (ST4038). The controller that I am using is the Western Digital Auto Configuring WX2. I have tried a bunch of different setups with this thing and I am at wits end... Drive C -- 20Meg Tulin 612 Track 4 Head (currently in operation) Drive D -- 30Meg Seagate 733 Track 5 Head (want to add) I have both drives cabled correctly and I now need to know the parameters for the Western Digital ROM Format program. I have tried various numbers in an effort to get this Seagate drive to operate half way. Currently the jumpers on the Western Digital Card are: 3, 5 ON Others OFF I have had jumper 5 off so that the controller will format drives using a user defined table, but I have not hit upon the magic numbers needed to make the Seagate ST3048 (Full Height AT Type 8 & 20) work. The numbers that I need are: Interleave Factor What works best? Total Number of Cyls Have used 733 Number of Heads Have used 5 Reduced Write Cyl Drive doesn't use this so what is the phoney number? Write Precomp Cyl ??? Correct Error Burst ??? CCB Option Byte ??? All replies are welcome. Thank you. Mike Mitchell cmcl2!lanl!myxm myxm@lanl.arpa All replies would be quite welcome.

I have since gotten help from the net and the system does in fact work. I have run a number of drive diagnostics (not ibm) in hopes that I might get it to fail. No luck there. For those who are interested, the seagate magic numbers are: 733 5 732 732 11 0 What would interest me is what that 0 does. They say it is for a CCB option byte but what is the CCB and what do other options perform?? Thanx. Mike Mitchell myxm@lanl.arpa

Also: do you not need to execute a low-level format first ? Or does the "Auto Configuring WX2" take care of that for you ? greg pavlov, fstrf, amherst, ny

Just for the record........

The western digital controller seems to be onw of the more adaptible controllers that I have worked with. Since that first posting, I have managed to get the western digital to support a number of drives of different sizes running simultaneously. Currently it is running the 20Meg Tulin and 30 Meg Seagate combination. It has run a 20Meg Tulin/30Meg Tulin, 20Meg Seagate/20Meg Seagate/20Meg Tulin/10Meg IBM(??) as well as toher configuratons.
