Jlanka and Phsstpok,
I would have thought that you both were correct; nonetheless, the results don't seem to pan out.
First, only the MiniPort Driver will install (the IDE Filter Driver is rejected by WIN2000). When the MiniPort driver does install, it essentially comes up as a 1999 Microsoft SCSI driver (like the installation guide indicates). At that point, I was excited.
Unfortunately, when I ran SiSandra for File performance benchmarks, I found that the system slowed down to 25.8 gb/sec from 27.3 gb previously, both relative to a presumed 29.2 for an ATA100 80gb drive as a comparison. Of course, I understand that comparing this drive to the theoretical ATA100 may be off, but when it slows down relative to the Microsoft IDE driver, things must not be working well.
I don't know how to translate XX gb/sec into 133mhz to get any clue about what is going on, or even if that is possible. Presuming that the SiSandra standard is OK, I would have expected about 35gb / sec. Alternatively, with the ATA133 driver working, I would think that my original 27.3 gb would have increased 20% to 32.8 gb (according to Maxtor, an ATA133 drive runs about 20% faster than ATA100 after overhead, etc.) So, no matter what, I would think that this performance factor ought to be in the low 30 gbs, rather than the mid 20 gbs.
Hence my conclusion that even though the MiniPort Driver installed, since it slowed the system down, something still isn't right.
So far, you folks have been putting me onto the right track. It is, however, still mystery meat about why the drive is running slow.
Thanks very much for your help.
Best regards,
nvs
