  1. Paul, I don't know where you get the info from, but I have an Extreme IV in my lab right now that works as a real HD running windows XP and is in UDMA IV. I am not familiar with Lexar's design, but the one with SanDisk with binary memory (Extreme IV, Industrial, and Ducati) can be used as a HD replacement to a certain extend. The difference between that and their SSD line product is the interface (SATA or CF, which needs adapter to work as PATA), and the wear leveling's robustness for desktop usage profile. Remember, the performance of Extreme IV's 40MB/S is for FAT file system, NTFS has a lot more writes for integrity reasons and that will not run at 40MB/S. The SSD from SanDisk is of M-System's design and it uses a different flash access engine that is more suitable for windows' main drive. You got to be very careful on what each brand's promise and reliability. A no name Taiwanese brand may work for 1 week at 300x, but it may not have enough wear leveling to last the warranty period, or it may have only 60x performance in random usage pattern. It is hard to tell without doing some real testing in a controlled lab. If I were you I would buy what Dell is ordering right now, they have very through acceptance test to protect them from bad design and poor quality. From what I understand, Samsung and SanDisk are both approved, but not Lexar yet.

    Bad sectors on HDD....

    The score of reallocated sectors at 180 and a raw value of 13C (316) means that it already has 316 bad sectors reallocated, it is getting close to the threshold score of 140. I would say you should replace the HD asap since there are probably not many spare sectors left. As far as useful life this drive is almost done. The value of Uncorrectable sector at 200 is score, the raw value is the one that counts, at 8, so it is not too bad. A drive in its prime condition should have 0 or almost 0 reallocated sectors.

    Fragmenting RAID volumes

    Fragmenting in logical disk is the same in RAID or multi disk volume. You want to maximize the continuous data in any single volume. This reduce software overhead, as well as seek within the same disk in the array. Unless you get the file to fragment exactly where the strip between disk split (almost impossible), a fragmented file will still be slower than a continuous one.

    Replacement

    If you by chance find a hard drive with the same firmware version on it, it will be very safe to swap the PCB. If you found one that has different firmware, but close in the ASIC silk screen (same chip) and manufacturing date, then it is probably safe too.

    What to do with old hard drives

    For something greater than 40gb, I would use them to upgrade other pcs. For something greater than 20gb, I would use them in external enclosure. For something greater than 10gb, I would give them away for free. For something smaller than that, take it apart and salvage the magnet, and put those magnet inside my car's engine or transmission drain pan to collect metal particles.
  6. 100 power cycle per month is very light duty. I would imagine the wear and tear on the drive by keeping it running would be higher than the 100 load/unload. If you are still worried, have a longer wait time before it goes into sleep as a compromise.
  7. Yes, that is the problem. Got it fixed now, thanks. Another question. When I slipstreamed the SP4, the new CD I created will prompt me to insert the SP4 disk if I use it to boot and install windows. I only slipstreamed the i386 directory. Do I need to do more?
  8. A related note: if you haven't already done so, create a slipstreamed SP4 installation CD and use that to install from. A whole lotta bugs were fixed between the original 1999 release and SP4. That's a great idea. Can I also slipstream drivers into the CD?
  9. Still have the Fast Ethernet PCI card? i am interested. Is it a small or large item?
  10. The configuration is as followed: 2 7200rpm PATA drives (recycled 120GB), connected to Promise FastTrak 100 as stripped 1 PATA cdrom connected to MOBO Secondary Master 1 1.44MB floppy connected to MOBO Try to boot Win2K installation CD to install, and press F6 for SCSI driver, but it couldn't find driver on the floppy. I tried downloading the driver again and again, from Promise, and still couldn't find it. The same driver works fine if I install windows on a single HD connected to MoBo, and have a stripped array connected to promise. Any suggestion on what may be wrong?
  11. There should be a spec for each standard, and manufacture should have those info on their website. Those standard are typically "worst case" consumption, so if you want to know which one consumes more/less, you really have to look up from manufacture. IMO the smallest card from the latest design usually use smaller processes on the NAND and that consumes less power, but make sure you get the plain vanilla low performance model, and smaller size, so you are not getting 2 or 4 chips version. Oh, name brand usually have better power management firmware than generic, so they usually consume less power.

    what's "BE" in smart parameter?

    Might have been a vendor unique value. Since you say it is fairly new and it is rapidly decreasing to threshold, why don't you call the manufacture's tech support and ask them?
  13. Eventually they will switch, but when?

    Not Enough Memory to duplicate

    Use another software that doesn't copy the whole thing to ram at a time. How "accurate" do you need it to be? If you are just copying partition to partition, I think any drive manufacture's utility burn onto a CDROM to boot will work.
  15. Sounds good, where are you located at?
