    I'm Looking For A Good Lcd

    FWIW, I don't have the specs you require, but I do have some LCD experience. My current setup uses two DVI powered Viewsonic VP171b. I like the very much. Included the pivot feature which I use extensively in my work (document preparation for my lecture courses). Now: they are 17's limited to 1280x1024. But, the line is quite nice, assuming the quality of the larger panels in the line are similar. I'd at least recommend you check them out, as I found them to be quite competitively priced. I've also got a 15" Dell Ultrasharp on my wife's computer. Also like them very much, but pricing isn't as generous. I believe the model is the 1504... Be a little careful with Dell's. Their smaller panels come in two varieties... and not all are created equal. Good Luck. CEM

    Ok storage gurus, help a friend in need.

    JBOD=spanning, not striping. I am not aware of any method that will allow you to pull a given drive from a span, and replace it. Remember that the trick that a controller or OS is playing here is to map all those little bits from all drives to a single huge File table. The normal rules of data storage apply to that file table. There is no way to tell the file table, to my knowledge, don't write anything to this particular 2.4GB of the disk, so that you could then pull it out. hope that isn't dissappointing to you. CEM
  3. There also is the issue of hydrogen pacification depletion, and a bunch of other rot... Charles
  4. :wink: Actually yes, but not one that was intended to be. I had a bad external cable (this is just a couple of days ago), and my IBM 36lZX U160 drive kept negotiating 8bit LVD (40MB/s) . narrow LVD is, to the best of my knowledge, a still born specification. It exists, but as you correctly point out, never saw the light of day. Charles
  5. Well, I finally took the plunge and ordered the PCPower and Cooling Silencer 400. Not cheap, but worth it. That about sums it up. $169 for 400W (actually 425, but it is listed at 400). BUT- Quiet, even under heavy draw, and tight tight tight regulation. How tight? Well, the hardware monitor in my bios used to read things like 12.25, 5.15 etc. with my old Enlight 300W. Now they read 12.01 and 4.99. That's tight. Glad I did it. I also plunged and ordered some good Panaflow L 80mm fans. Decent airflow and low noise. These beat the hell out of the buzzsaws they replaced. Two fans in my Antec 830SX seem to be keeping my CUV4X-D with dual 1GHz PIII's under 35degC under load! One fan blows in across the HD's (1 IBM 36LZX 9.1, 1 Quantum Atlas 10K II 9.1, and 1 WD600BB 60GB), and one blows out the back by the processors. Very happy. Another thing I ordered was a rounded 50pin scsi cable from plycon.com. The construction is ok (this is the beige type, not the silver), though not all that inspiring. It seems to be ok so far, though I'm going to test the burner a little more thoroghly and rip some audio and dvd's first before I pass ultimate judgement. What the rounded cables do, though, is improve airflow. Plus the Rounded is much easier to snake through my case than the huge flat ribbon, 7 position beast it replaced. :roll: Now I need to snag a rounded silver floppy and ATA 100 cable, and I'll be all set. Don't know if I'll trust the U160 roundeds, though. Seems a bit much to expcect.... Well, if anyone was waiting for a beta tester for any of the above.... your wait is over... Charles
  6. Actully, 8bit (narrow) LVD starts at 40MB per/second and 16bit (wide) LVD at 80.
  7. The two prevalent electrical specifications that you and I use (SCSI) are SE (single-ended) and LVD (low voltage differential). Those terms refer to the measurement method for voltages on the lines of the SCSI bus. Single ended most commonly refers to a two conductor arrangement (ground-signal) whereas LVD refers to a three conductor arrangement (signal-ground-common). In lvd, rather than measure the voltage between the signal ground pair, you measure the voltage between the signal common pair and the ground common pair individually, then look at the difference. The benefits of lvd are better common-mode-rejection, etc. The result you and I see is extended cable length, higher frequency transfers, lower drive voltages. BTW, there are other electrical SCSI specifications: HVD (high voltage differential) and FCAL (fiber channel), with the latter actually being a different physical spec (fiber optic rather than copper). Hope that helps, Charles
  8. Thnx all for the input. Charles
  9. BTW, please continue your critiques of the PCPower and Cooling PS's. The specs are really good, but it's always nice to know if the people buying them find that what's on paper matches what's in the box. :wink: Are there other brands with which PCP&C compete in this 'high-end' market segment? (other than other lables selling the same PS). Charles
  10. One question, and this is a subjective one: at what dB rating would you consider a fan to be considered quiet? The papst and silencers are at 20dB or so, and low 20's in CFM. Others weigh in at 30-35dB, and push closer to 30CFM. I've got 5 fans, apart from the PS in this Antec case, so I can go to lower dB fans with less CFM and still generate good airflow. Actually, maybe a better question to ask is: what is a dB rating where you think a fan starts to sound loud...
  11. I think that is a good point... I anticipate there are differences between 'cheap' and 'quality' lines. A good fan would have a lower dB rating at an equivalent RPM than a poor one. For a given fan, low RPM would produce fewer dB than at high RPM. So I guess my question could be boiled down to: Do you feel quality, low RPM fans (with a low dB output) provide a noticeable difference from a generic fan?
  12. Well, I'll broach this subject again, though it has been asked many times... My situation: Cases: Antec 830SX With 300W Enlight PS, and various (5)Adda and Sunon 80mm fans (nothing special, just cheapie fans). And 1 Antec KS004 External SCSI enclosure with U160 cabling, AT PS and 1 Sunon fan. I'm going to upgrand the PS in the 830. I'm considering a PCPower and Cooling supply. Question 1: are they still good? as good as their reputaion implies? Question2: if they are good, what is the real difference in the turbo-cool 425 and the silencer 400? the specs are identical, except one uses a quieter fan with lower CFM. Otherwise, the current outputs on all channels, as well as the regulation are speced the same. If so, it seems that the silencer would be a logical choice... (price is the same). Which brings me to the second part. My fan noise has started to bother me, for the first time ever. As such, I would like to upgrade to some quiter fans possibly even thermal sensing... especially if I opt for the quiter PS... Who here has tried the quite fan route, and does it help? Bear in mind I don't mind some sound, but lately it has been a bit much... I realize that 8 fans total are going to make some noise, but would quality fans such as high end sunon or papst or sanyo denki make a noticable difference.... Thanks, Charles
  13. i concur with your original plan.
  14. Your plan sounds good to me.

    ATI Radeon 8500DV under Linux?

    The DV card has vid cap capability? if so, does the linux driver set include vid cap?
