    my hard drive is no longer appear in the bios

    You tried this drive on 4 different systems and got the same result on all of them?? I still have no idea what you mean when you say that "mother board say there is a hard drive in this sata slot but no other info". My experience has been that if the BIOS detects a drive it also reports basic info about it. If the BIOS is unable to get the drive to respond to a basic ID sequence on four different systems then I expect the drive is dead. Or at least it is dead enough to be replaced if the drive is still under warranty. If the drive is not under warranty then I have no other suggestions for you. As for where to get the firmware ... assuming there is an updated firmware ... that would be Western Digital. Talk to/email their support reps again. If you download and try to install firmware from anywhere else on the net, &deity. only knows what you will be getting/using. OTOH, chances are you would completely brick the drive so it would not respond in any way. That would be a problem resolution of some kind. -irrational john

    my hard drive is no longer appear in the bios

    I agree with the previous post. Installing firmware to a hard drive is always a last resort. I would never even consider it unless I was able to download the firmware directly from the manufacturer, Western Digital in this case. There are lots of other reasons why your drive may not be properly detected by your system but the most likely cause is simply a bad connection of either the data or power cables. It's hard to make suggestions when you have provided so few details about what is not working. In particular I am not sure what you meant by "now it cant be seen in the bios but the bios say that there is a hard drive in this sata slot". Just what is the BIOS saying about this drive? What motherboard/CPU combo are you using? Have you tried the drive in another system/motherboard or in an external enclosure? What operating systems are you using? Is this WD your primary drive? If not, what other drives are in the system. Are you using RAID? -irrational john

    Seagate Promotes SmartAlign Software

    I doubt that Seagate would want to do anything as implementation dependent as reading a partition table. That requires too many assumptions about how the drive might be used. I think Seagate would want to keep SmartAlign as dumb as they could. My guess ... and since I can't find any info anywhere guessing is all I've got ... is that Seagate just added extra smarts to their caching algorithms to ensure that they do as few "read & modify & rewrite" writes as possible. But I have to wonder if it were so "easy" to "fix" things why wouldn't Western Digital have also done that? So I'm probably missing something ... -irrational john

    Seagate Promotes SmartAlign Software

    Yes, of course. But again the question I would like asked is how does Seagate's SmartAlign do this? I'm familiar with the utilities that Western Digital makes available and in that case I understand that they essentially relocate partitions so that they are properly aligned. However, Seagate appears to claim that this separate step does not need to be done with their SmartAlign thingee. For example, Seagate's SmartAlign technology automatically manages misaligned partitions in real-time inside the hard drive without the need for any software utilities. So, what's up with that? Nobody seems to bother to ask ... What exactly is Seagate claiming? Just plug one of their 4K drives into a Windows XP system, format it, and it "just works"? -irrational john

    Seagate Promotes SmartAlign Software

    The truly amazing thing to me about Seagate's magical SmartAlign Technology is how many times they can mention it without ever saying a bloody thing of any consequence. Has anyone anywhere said anything about how SmartAlign works? What does it actually do? If so, will you please step forward and share? It as though all tech reporting boils down to now is rewording press releases. Sheesh. -irrational john

    New HDD burn-in routines?

    I am also not comfortable letting my drives get "too hot". But I also remember that one of the unexpected results from Google's drive study was that there was not a clear connection between higher operating temperatures and higher incidences of drive failure. Higher utilization of the drive also did not imply higher failure rates. Go figure. BTW, I believe this Google report also indicates that Google doesn't use so-called "Enterprise class" drives. Or if they do use them, they also use a large number of regular comsumer class drives. The excerpt below is from the beginning of section 2.2. I added the emphasis. More than one hundred thousand disk drives were used for all the results presented here. The disks are a combination of serial and parallel ATA consumer-grade hard disk drives, ranging in speed from 5400 to 7200 rpm, and in size from 80 to 400 GB. -irrational john

    newbie questions - where to start

    It would probably help clarify things if you gave a little more detail on how you plan to connect these internals drives. Are you going to mount them internally in all the Macs? Or are they going to be in USB connected (??) external enclosures? Or something else yet again? The reason I ask is that typically you can pay more to get a higher performing large capacity drive. But paying extra for performance is not really the way to go if your performance will always be limited by how the drive is connected. (IMO paying extra for performance in a large backup drive doesn't make sense either since typically you just start the backup and "walk away". But to each their own ... ) I intend to take a look at that thread in a bit. But out of curiosity, would one be able to find info on burn in routines that would work on a Mac there? -iJohn
