Les plateaux tournent autour d'un axe entre et tours par minute dans le sens inverse des aiguilles d'une montre. En simplifiant, le disque dur s'organise en plateaux, cylindres et secteurs. On appelle cluster la zone minimale que peut occuper un fichier sur le disque. Pour pouvoir stocker toujours plus d'informations, il a cependant fallu trouver un autre moyen de stockage plus performant. Bref, c'est l'impasse. Sachez que MO par seconde suffisent largement pour toutes les applications.
Le Sata dispose cependant de nombreux avantages :. L'histoire du SCSI commence en Le processeur ne fait que dialoguer avec la carte SCSI. Pour pallier aux performances stagnantes des disques durs, les constructeurs leurs ont adjoint un cache. Le cache sert de relais entre le disque dur et le processeur. If not you will need to find the motherboards web site. It sounds like your computer is a very, very old one.
The problem of not reading the full capacity od very large HDDs was common going back 8 or more years ago. The problem was, or in this case could be , the computer does not have 48bit logical block addressing.
You'd have to enter BIOS and look around to verify this. Really, just LOOK, until you understand what you are doing. Updating the BIOS is a particularly risky operation, and you should avoid it unless absolutely necessary. Investigate your HDD makers website for a possible software workaround, it will be a free download. If you just bought this computer new the day before yesterday, please ignore all of the foregoing.
I went ahead before I saw your comment captain cranky and I update bios. Now I have blank black screen. Any suggestions? You can now justify the expense of purchasing a new computer. Put the new Gb hard drive in a USB caddy and you are all sorted. Tiger said:. Click to expand Captaincranky how could you be so rude as to suggest that the poster may be unable to pay for a new machine? I suspect the problem is that the partition was created with XP prior to SP1. Or was it SP? What I would have done is made it a gig partition, installed XP.
Done the updates to SP3, then used gParted to resize the partition to the full size. SNGX said:. An excellent point there.
It's rarely clear at the outset how experienced a poster is. When the BIOS update was proposed I'm sure we were aware this could be sudden death for the computer, particularly when attempted by a complete novice, but no one likes to immediately post, "No!
Don't do that. No one has been intensionally rude. I had my tongue in my cheek not sticking out. The really rude folks are long gone from forums and are presumably trolling on sites like Facebook.
What I should have said is that the situation is now so bad that it will take a lot of luck or technical expertise to get that machine up and running. Time really to buy another PC - new or used. A technical post mortem is likely to be little comfort to Tiger So, how could have any partition have been created with any version of Windows. If he created a GB partition upon install, there's no reason to start a thread.
Or, the thread would topically be more along the lines of, "I created a GB partition when I installed Windows, how do I get rid of it"? If this was only going to make a GB partition, it would have told you so. Actually, I think you are not totally correct. XP prior to whatever SP allowed you to go beyond GB just makes a GB one if the drive is larger, since the OS doesn't recognize anything larger, it doesn't even know there is more there.
We're both saying the same thing. The drive doesn't know the extra volume is there, and that's the 48LBA issue. My argument is speculative. You're saying the update takes away the GB? I'm reading now, with the update, 48LBA is functioning. Ostensibly, the computer should now know it's there Yeah, I figured out we were kind of agreeing a bit after I posted.
I can't test it to be sure, but I'm saying that if you let XP virgin install itself to a larger than GB hd, so a or greater going with common sizes it will make that entire disk GB. So then later if you upgrade to SP1, you are hosed, no new space is there because the entire platter s were used to create So the only way to get that back is to wipe everything and start anew. However, if you had choosen to make a GB partition and leave the remainder unallocated with XP no SP then upgrade to SP1, you will see the remainder of the real size of the disk in Disk Management.
