This new info came out of a table from Mini-Micro Systems Magazine (p111, November 1987). One thing to note, if you look at this table, there are a lot of listings for drives with something greater than 191.2 MBytes. As far as I can tell, these products really are drives from other companies that are modified in some way (i.e. a different controller) to squeeze out the extra space. This type of product will not work with the Western Digital controller in the unix-pc, so take the information in table with a grain of salt. Before I start, there are 2 things. First, I still don't understand much about how 2,7RLL encoding affects the st-506 interface. Can I drop a drive into a stock unix-pc that has 2,7RLL encoding and have it work without any other modification or not? Any help here would be appreciated! Secondly, I want to mention that I don't if any of these drives actually work with the unix-pc other than the fact that they are advertised as ST-506 copmatible. If you KNOW that they work, let me know and I'll post results when appropriate. By the way, the ST-506 drive that wins the capacity prize is Priam Corp's model 519 drive weighing in at 191.2MBytes (San Jose CA 408/946-4600), any experience out in netland with this baby? Anyway, here is the most complete list I can compile right now: Model Height Size Ave Seek Heads: Recording unformatted time Cylinders Method ========================================================================= ----------------------------CONTROL DATA--------------------------------- FWCDC48 Full 48.20MBytes 28msec 5:925 MFM 94205-51 Half 51.__MBytes 28msec ? ?
