  1. BluRay is going to ship with a recording standard/format already in place. (At least thats the plan). For the forseeable future though, its going to be rather expensive. Even Dual Layer DVD recordable media is pretty expensive.. but BluRay is in a whole other world of expense, at least right now. I think there are already BluRay recorders that can record up to about ~23GB of data on a single disc; but they cost in the thousands, and the discs make dual layer DVD media look cheap. If you search on google, you'll see some scattered info about Blu-Ray, and reviews of the few recorders currently available for sale (most in Japan I think)

    ATTO SCSI cards have support under OSX, and are what my coworker uses in his G5. He only has a UL3 series card in his, but the UL4 series cards support PCI-X and also have OSX support.

    Noise Driving Me Crazy

    I'm not a total PC silence fanatic, but I do like my systems to not sound like portable generators I have one system with a Zalman CNPS 7000A AlCu heatsink/fan and I'm pretty happy with it. It comes with a Zalman Fanmate too; so you can adjust its fan RPMs, but even at max rpms I can't hear the heatsink fan over other louder components in my case. Keeps my 2.8C@ 3.08 Ghz fairly cool; right now MBM is reporting 45C while running D2OL, ambient temp is 25C. (yes I know mb temp reports are not that great, but its not bad for something I really can't hear) The only maybe worrisome part of that heatsink is that the 92mm fan is built in and not really a replaceable part. So far its been quiet, but if it ever gets loud you'll be stuck with it unless you are willing to yank it off and try to align another fan in the same spot and glue (I think its glued on) it down.

    Hmm, someone at work has a G5 attached to some jbod drive array; I think the drives in it are IDE but the interface is SCSI. Theres gotta be some support for fancy storage systems on G5s, as there are HD video editing apps running on it. For some reason, most of the people in the editing industry are obsessed with uncompressed video (they don't like even lossless or slightly lossy formats).. and when you need to do HD uncompressed, the drive bandwidth required is bordering on ridiculous.

    Ibm Readies Dual-core Powerpc

    Heh, Motorola has dropped the ball multiple times now. It even really hit the floor before the G3 (the PPC 740) was luckily found among the other PPC based processors when Motorola totally botched the PPC 620 project (ironically the first Power chips are descendants of the 620). It really seems like Apple is finally fed up, and is glad for IBM's codevelopment of the PowerPC architecture. Still, despite the G5 being ridiculously fast, its also caused a fairly large number of incompatibility and even design issues with existing Mac software and hardware; which was already in a state of flux because of the OSX transition. Hopefully future developments won't make things worse. Macs are fun but really, I would not buy one in the foreseeable future.
  6. SATA controllers (especially motherboard ones like the ones built into Intel ICH5 and ICH5R southbridges) won't show up in a separate "SATA controller" category. Addon ones from Promise will probably actually show up in the SCSI controller category, because of how their drivers are written. SATA is STILL an IDE variant, it just happens to extend the spec a bit, and use different cabling. (a more extreme version of the IDE/EIDE switch and the UltraDMA66-100 cabling switch) As far as Windows knows, they're just another IDE controller. One of the primary IDE controllers is what is controlling the Raptor. Checking its advanced properties will probably reveal its UDMA Mode, though again, WindowsXP is probably still going to report it as UDMA 5 (UltraATA 100), because it doesn't know about anything else. I've never used BootVis.. but maybe it cannot detect the cache settings correctly because the IDE controller drivers are not the Microsoft built in ones?

    Poor Samsung Performance

    Hmm, ok you can try removing the IDE controller in device manager that the drive is attached to, and rebooting (Windows will reinstall it on reboot). That sometimes lets Windows redetect the drive at its proper speed. Sometimes Windows will fix a drive in PIO mode if it detects too many errors (real or not). Removing the device usually clears that up; but if it still doesn't I'd start suspecting the cable or the drive itself.

    If the 9600XT is still within your price range, it is faster than the 9600 Pro. The increased amount of memory on the 9600 Pro you picked is not really helpful at all. (and by the time games do want that large amount of memory available, most of the current cards will be too slow to keep up anyways)

    Please Help Me, Thanks

    There are only a few Nvidia based cards that are competitive at all, and the FX5700LE is not one of them. How much are you willing to spend on a video card? ATI Radeon 9600 and 9600 Pro based cards are in the same price range as that card, and faster. The 9600XT is a bit more, and faster. The next one up is the 9800 Pro for around $200 US. All of them will run Farcry.. though of course faster ones will run it better I think you might occasionally see a good deal on a Nvidia 5900, but I don't think its very competitive with the 9800 Pro at its usual prices. 5700 Ultras are ok too but still a 9600XT is comparable, if not faster for around the same price.
  10. Seems like they are gaining confidence in the SATA versions of their drives? Newegg listed the one I got as having a 3yr warranty, but I sort of figured it was a typo. According to Seagate's page and their warranty checker, my drive does indeed have a 3yr warranty. Maybe they are going back to their 8MB cache = 3 year warranty policy again? Also someone posted earlier about the difference between the ST3120026AS and ST3120022AS drives. Its not at all made clear on their website, but the little OEM manual that came with mine says that the 22 is a 2 MB cache SATA drive.

    Sata Seagate

    Hmm.. I was afraid it would do that... ok well follow Ron's advice first and install these: Intel Chipset Drivers from Asus's site if you haven't already. If for some reason after installing those and rebooting, the drive still isn't behaving properly, for some reason Windows thinks its detected too many read/write errors on that drive (sometimes from driver issues, but can be cause for concern about the drive as well) You need to go into device manager and right click on the Primary IDE channel that is connected to the SATA drive and stuck in PIO mode and select Uninstall. This will uninstall the driver for that controller and clear out any old settings.. after a reboot it will redetect and hopefully go back to DMA mode. If the channel is set to DMA if Available and the drive is still stuck in PIO mode after this change, the drive electronics or maybe your SATA cable are probably defective.
  14. Megadeth

    Sata Seagate

    The second Primary IDE channel IS referring to the SATA controller. IDE controllers generally come in pairs, Primary and Secondary (you won't ever see Tertiary or Quaternary or whatever the heck would come after those first two) And you don't have any other IDE drives in the system at all right? By process of elimination.. that would pretty much prove that the SATA drive is on the second Primary IDE controller. Like others and I have said.. you should change the mode on the channel that is set to PIO only to use DMA if Available. In a modern system there should be absolutely ZERO devices using PIO mode at all. BIOS settings merely set the maximum speed that Windows is allowed to use, the Windows driver itself is limiting itself to PIO mode in your case. Change the setting and reboot.. if you set it to use DMA if Available and the device still shows up as PIO only, post back here.
  15. Megadeth

    Sata Seagate

    The use of PIO mode only is what is crippling your transfer speeds, in PIO mode, your CPU has to handle every last bit of data read and written to the drive. Even the fastest CPUs can barely manage over 4 to 5 megabytes/sec when ahving to do this. You need DMA mode active to let the drive and controller dump data to and from system memory with minimal CPU overhead. if changing the setting in device manager and rebooting doesn't change the mode of the 2nd hard drive from PIO to UltraDMA Mode 5 or something, post back here and I will tell you a more extreme method for making Windows change the mode And again, the SATA drive will not lilkely be any faster than the PATA in just sustained transfer rate, as they are both Seagate 7200.7 models, and should have almost identical STR; the only difference is extra cache on the SATA which should have minimal impact when measuring just sustained transfer rates like you are. The one area where SATA can help vs PATA is in burst transfers out of the cache; the rest of the drive is not fast enough to fill up the bandwidth of either interface.

    Hmm.. well whats your budget? You can get a variety of low end (and if you are lucky, prosumer level stuff like Vegas) video editing software with various bits of hardware, as people have mentioned earlier. See if you can get your hands on a copy of something like Pinnacle Studio 9 (8 is kinda buggy.. I'd avoid it unless its REAL cheap heh just to get started with things. It has plenty of effects and is pretty easy to use; but the same can be said for many other sub $100 pieces of software. It also has a few different ways to actually edit your video.. ranging from simple drag and drop, to a real timeline type setup like higher end software uses. I don't have any experience with Vegas, but I do use Liquid Edition on a pretty regular basis, and I find it MUCH better than for instance Adobe Premiere.
  17. Heh, plenty of the desktop and even a few of the server chipsets out there behave poorly when put under server type heavy I/O situations. Its way too easy to generalize about these sort of things by brand. Still, Via probably has the worst record out of the bunch on that count.. especially with the PCI bus hogging SB Live + Via 686B southbridge data corrutption fiasco. Plus in general people like to rag on their slower than most PCI bus performance too. Maybe only Serverworks has never really released a bum chipset at some point.. AMD's much lauded 760MPX chipset has issues while under heavy I/O load as well, some of Intel's (non Serverworks based) later P3 chipsets were not wonderful either. From personal experience, recent SIS chipsets have been pretty good stablity and performance wise for the few desktops I've built with them. And you definitely can't beat the price on most SIS based boards.
  18. Nothing that horrible with software RAID; crappy "hardware" RAID solutions are no better and are often worse. Unfortunately, only Server versions of Windows (NT4 Server, W2k Server, and Windows 2003 Server) support any sort of software based disc redundancy. Win2k Pro and XP Pro I think support a sort of RAID 0 software striping, but thats it.
  19. Battlefield IS pretty horrible on the loadtimes and on still caching data while you're in game. I think it affects all systems to some extent, though you probably won't notice it so much if you have fast HDs.. Your friend also only has a single HD? I know that Battlefield 1942 loaded and cached its ridiculous amount of map/game data faster when I had it on a separate drive from the OS. It could just be that your particular drive is not very good at doing what the games you are playing ask of it (look at the OS loading benchmarks SR runs, in a few cases, otherwise kinda sluggish Seagates win out). What other games are you playing that are slow? I know Battlefield is a hog, but UT2004 is a bit less of a hog. His SATA ports are from the VIA 8237 Southbridge, they are not controlled by a separate chip.

    Building A Home-use ~2tb Storage Server

    It is spread across multiple arrays.. and in addition to that, you can combine multiple raid "levels" to get larger arrays with different performance. Here's a site with simplified pictures of the various RAID levels (a few of which are really no longer used) http://www.ecs.umass.edu/ece/koren/archite.../basicRAID.html Two commonly used levels are RAID 10 and RAID 50. RAID 10 is striping and mirroring combined, so you are basically mirroring 2 striped arrays; so you get the speed of RAID 0 with the redundancy of RAID1, though you're still losing half the capacity to the RAID1. RAID 50 is another popular solution, where you RAID 0 stripe two RAID5 arrays together for increased STR; while still retaining some redundancy; but not sacrificing as much space as RAID 10.

    Building A Home-use ~2tb Storage Server

    Hmm, bunch of answers/responses to the posts here heh. One thing to watch out for when using the 75xx/85xx series 3ware cards with large drives is the fact that they don't support arrays with sizes larger than about 2 TB per card. So your choice of one of the new 9000 series cards is a good one.. I guess the 2 TB limit issue would only happen when using the 12 port cards with 250 GB drives, or much more easily when using the upcoming 400 GB drives. One thing with the 9000 series cards and their onboard cache though; the battery backup that lets the cache keep its data intact if it doesn't get a chance to write it out to disc in case of a power failure is apparently not yet available. A UPS would definitely be advisable for a system of this sort anyways. RAID5 is a (Capacity/Drive Size)+1 solution, regardless of the size of the array and the drives in it, virtual or physical, all have to be the same size. You CAN use part of a 250 GB drive in say an array of 180 GB drives, you'll just only be using the first 180GB of the 250 (and a lot of controllers I bet don't support this either, though most software RAID solutions do). So (8*400)-400 = 2800 GB, and (400*6)-400 = 2000 GB. With regards to 100mbit.. and user count, totally depends on what the heck the NIC is actually serving packets out for. For a webserver serving mostly text mixed with some images, 100mbit is plenty; for a server that is serving out DV25 video that needs to be played backwards/forwards/slowmo flawlessly etc... try 2 clients on a 100 mbit line tops.

    Which P4 To Choose

    Any idea what video editing software you'll be using? Their demands on hardware (CPU and in at least one case GPU) vary greatly.

    Windows Xp Slow

    Hmm interesting.. never used that command in XP, and it doesn't seem to be present under 2K Pro. Next time I see a customer machine with that virus thats also running XP I'll see what happens That command would also be good for catching virii/trojans that are being run as services.

    Windows Xp Slow

    I take Your word for it and You're right that they can "borrow" any name they want. A svchost.exe running at 40% CPU is a candidate for suspicion. What will cmd show for tasklist /svc with regards to a virus under that name? Christer Hmm, what do you mean by tasklist /svc? I'd just look at task manager and see a svchost.exe that is eating resources like mad, or see two explorer.exes, one of which is the virus.
  25. Megadeth

    Windows Xp Slow

    I have 3 svchost.exes running; but I've definitely seen virii masquerade as Svchost.exe and as Explorer.exe. Nothing is stopping a virus writer from creating a virus with those executable names.
