How to change from UDMA5 to UDMA6
I have a Gigabyte GA-8IPE100 motherboard with Intel(R) 82801EB Ultra
ATA Storage Controller built in, my two SATA WD Caviar hard drives supports UDMA6 but in windows XP UDMA is auto choosen for both drives. How to change that to UDMA6, is it a hardware or software problem, in BIOS I only have the option of Enable or Disable UDMA, in my motherboard manual it says it supports 150 MB/s operation mode. I tried some registry hacks but it doesnt work, both drives performance is arround 60MB on sequential Read/Write, is this the best performance? Please HELP. -- ---------------------------------------------- Posted with NewsLeecher v3.5 Beta 4 * Binary Usenet Leeching Made Easy * http://www.newsleecher.com/?usenet ---------------------------------------------- |

How to change from UDMA5 to UDMA6
the 150 is cache burst speed, 60 is reasonable for a sustained read/write

How to change from UDMA5 to UDMA6
Okay, but what about the 5 and 6 modes, drive says it supports 6 but
windows choose 5, so is it the motherboard? and is there a tool to check the if the board/controllers supports UDM6 ? I have sandra but it doesnt tell, or maybe I dont know where to look. I am all new to this transfer performance issue, so excuse my ignorance. -- ---------------------------------------------- Posted with NewsLeecher v3.5 Beta 4 * Binary Usenet Leeching Made Easy * http://www.newsleecher.com/?usenet ---------------------------------------------- |

How to change from UDMA5 to UDMA6
I think it is limited by the board

How to change from UDMA5 to UDMA6
I know for regular IDE drives the Western Digital's came with a floppy that you could set the UDMA
with. You may want to check to see if they are actually at 6. If they are then maybe the motherboard needs to be checked to see if it indeed supports the 6 speed. The specs of the board from the manufacturer should tell drive speed support. You will not notice the difference between the two if you are able to switch to 6. -- Dave Vair CNE, CNA, MCP, A+, N+ "Mondo" wrote in message ...

How to change from UDMA5 to UDMA6
Thank you guys for your help.
I know for regular IDE drives the Western Digital's came with a floppy that you could set the UDMA with. You may want to check to see if they are actually at 6. Dave my WD does not come with a disk and could not find any tool to change the UDMA on WD site, only data Lifgaurd tools is there, its only for copying and partitioning the drive and giving infos about it, it says the drive supports UDMA6 and current is UDMA5. If they are then maybe the motherboard needs to be checked to see if it indeed supports the 6 speed. The specs of the board from the manufacturer should tell drive speed support. Nothing is told about that in the manual nor on Gigabyte's site, thats why I was asking if there is anykind of a testing tool that will give me such info. You will not notice the difference between the two if you are able to switch to 6. I get it that there is no difference in the speed from UDMA5 to UDMA6? If so how come I noticed a big difference between lower UDMA modes and UDMA5? Please explain more because if so then no need to bother trying to switch. Also on sandra file system benchmark I'm getting very low results (50+Mb/s) compared to other similiar systems (100+Mb/s), what could be the cause of this? Thank you. |

How to change from UDMA5 to UDMA6
The UDMA management tool was on the WD Diagnotics disk, I see that there are a couple of versions
there, I haven't tried the newer versions so I am not positive its on there, but that was where it is located in the older versions of their disks. AS for transfer rates, there are many things that can influence them, amount of memory on board, running items in the background, indexing service and virus scanners influence the speed at which stuff mves around. -- Dave Vair CNE, CNA, MCP, A+, N+ "Mondo" wrote in message ...

If so how come I noticed a big difference between lower UDMA modes and UDMA5? Please explain more because if so then no need to bother trying to switch. Because the limiting factor after UDMA 5 is the speed the bus system can deliver the data. There is no discernible difference betweeh UDMA5 and UDMA6. Before UDMA 5, you're limiting not only the cached speed, but also the sustained throughput speed by selecting a lesser mode for data movement. You won't see this in msdos, it uses throughput period, UDMA setting in the bios makes no difference. And may sometimes be visibly faster than in XP environment with current hard drives as there is no or little overhead in msdos. Do a little research on the hard drive cache, and how often its used in everyday use. Throughput is the standard for everyday usage monitoring. And throughput is limited by the bus system after UDMA5 mode. UDMA6 is hype, not results. Also on sandra file system benchmark I'm getting very low results (50+Mb/s) compared to other similiar systems (100+Mb/s), what could be the cause of this? The first may be a dried up (data not applicable on the cache to the SiSoft test) cache or not used, the latter is using the cache on the hard drive. The latter is burst speed, not throughput. Then there is also a concern for overhead, hardware monitoring software and so forth that can affect the results. I did alot of tweaking in the past. Hitting deadends maxxing what I had, and buying faster stuff. In the end, I decided to just use and enjoy the PC rather than spin my wheels and spend money that doesn't really make a whole lot of difference for me. -- Jonny |

How to change from UDMA5 to UDMA6
Thank you Jonny for the clarification, and yes I usualy try to enjoy
what I have and do not tweak alot, but I had some major problems with my hard drives performance lately thats why I was concerned. |
