UDMA3? Any errors in dmesg other then the ones you pasted? Also, when benchmarking with hdparm (as it states in the man page, it is good to run it 3 times for each run and take the average) as it can vary sometimes. I have also noticed if you are running hdparm -t /dev/hde when running X, window manager, etc, I get 8-10MB/s less vs. when I run it in single user mode. -----Original Message----- From: linux-kernel-owner@vger.kernel.org [mailto:linux-kernel-owner@vger.kernel.org] On Behalf Of Enrico Bartky Sent: Friday, November 12, 2004 10:44 AM To: linux-kernel@vger.kernel.org Subject: RE: PROMISE Ultra133 TX2 (PDC20269) mysterios, .. now it says udma4 but with 7 MB/s schrottkiste:~# hdparm -I /dev/hde /dev/hde: ATA device, with non-removable media Model Number: FUJITSU MPD3084AT Serial Number: 01064533 Firmware Revision: DD-03-44 Standards: Supported: 4 3 2 1 Likely used: 4 Configuration: Logical max current cylinders 16383 16383 heads 16 16 sectors/track 63 63 -- CHS current addressable sectors: 16514064 LBA user addressable sectors: 16514064 device size with M = 1024*1024: 8063 MBytes device size with M = 1000*1000: 8455 MBytes (8 GB) Capabilities: LBA, IORDY(cannot be disabled) Buffer size: 512.0kB bytes avail on r/w long: 4 Queue depth: 1 Standby timer values: spec'd by Vendor R/W multiple sector transfer: Max = 16 Current = ?
