was posting about earlier. I'm very wet-behind-the-ears Amigawise, so if anyone has any pointers about how to configure such a beastie (interleaving ? partitioning ? mounting ? possible problems ?) I'd love to hear them. It's, um, lessee 9 head, 5 platter, 1024 cyl. I've got an A2000 w/2090A controller. Any pointers/tips would be greatly appreciated (but please break it to me gently if it's: "congrats, you picked the one drive that cannot be used with an Amiga.") --mjr(); mjr@welch.jhu.edu

It's, um, lessee 9 head, 5 platter, 1024 cyl. > I've got an A2000 w/2090A controller. I've had the 155M Wren III for almost a week. According to the manual, it's 9 heads, 969 cylinders (only 967 "user accessable tracks" though) and a formatted capacity of 155.9 megabytes. A bit of backwards math gives 35 blocks per track, something the manual didn't say. Also, Control Data is being a bit optimistic with the 155.9 meg rating, that's 155,957,760 bytes, or 148.7 megabytes if you use 1024*1024 per megabyte. On the A2090A I'm unable to get Format to work without the "quick" option, but I'm told that the drive itself handles the bad blocks, so this should be no problem. I'm still playing around with the drive trying to decide the best way to partition it. (Any suggestions on small vs. huge partitions would be appreciated. UUCP/Usnet will be one use for the drive.) Oh, and according to CDC, the average access time is 16.5 mS. I get 550K per second with Diskperfa. It is a full height 5.25" drive, so you'll have to mount it outside of your 2000 somehow. Mine is in a PClone type hard drive case. -- Blaine Gardner @ Evans & Sutherland 580 Arapeen Drive, SLC, Utah 84108 Here: utah-cs!esunix!blgardne {ucbvax,allegra,decvax}!decwrl!esunix!blgardne "Nobody will ever need more than 64K."
