Does anyone use Hyperdisk with an SCSI Adapter? My configuration is: 386sx with TI chip set WD7000FASST SCSI controller DOS 4.01, 4DOS 4.03, buffers=20 Hyperdisk 4.21 QEMM 5.11 When I activate Hyperdisk and look at the caching statistics, it says that no sectors are cached and there is a 0% cache read hit. Hyperdisk is run by typing in hyperdkx; the statistics are shown if you run hyperdkx again. When I activate Hyperdisk and run WD's Testdisk program, I see equal or lower performance. Any help would be greatly appreciated...otherwise, I'll have to go back to SmartDrive..<ugh> Ken (kenyee@ksr.com or uunet!ksr!kenyee)

Columbia Data Product's disk-partition software isn't very compatible. Not very many caching programs work with it (SmartDrive *may* not be working with it! - I tried PC Kwik and HyperDisk and PC-TOOLS cache, none worked). Of course, there is a simple solution (well...) You need to <groan> backup your hard drive, low-level format it, and then high-level format/partion it WITH DOS, *NOT* SST-Setup. Using Dos 4.01 or the upcoming 5.0 you can get most of the benefits of the SST-Setup program (large partions, etc). I can't really think of any reason to use the SST-Setup program anymore... once you do re-format, you can use HyperDisk (AND IT FLIES!), not worry about stupid incompatibilities, and have a great all-around system. <grin> BTW, once you do re-format with dos, you can dump SSTDRIVE.SYS in your config.sys file. I recommend leaving DEVICE=SSTBIO.SYS; it doesn't seem to really speed anything up but thats what CDP recommended to me when I came to 'em w/ the same prob. BTW, the newest rom rev is 3.6.2 I believe. Again, seriously consider reformatting your drive with dos 4.01 / 5.0 (due out soon :-). There are many, many, many reasons for this which I don't know offhand but wept over 3 months ago (imagine backing up 300 megs onto 3.5" floppies...) -- Apple II Forever | 6600prao@ucsbuxa.ucsb.edu | IBMs get the job done Parik Rao | Amiga - for the creative mind | Class of 1994 Macintosh - buy it or Apple will sue you.
