Now forrepparttar transfer rates you're going to need to do some searching,repparttar 107754 best way to find these numbers is to go torepparttar 107755 manufacturer's website and look at specification sheet forrepparttar 107756 model you're looking to buy (actually this isrepparttar 107757 best way to get allrepparttar 107758 information I've talked about so far). One thing to look out for is that you may read something that says 133MB/s or ATA/133 or SATA150 or 150MB/s, and these are notrepparttar 107759 numbers you are looking for, those numbers describerepparttar 107760 bus connectingrepparttar 107761 hard drive torepparttar 107762 motherboard, and are theoretical peak numbers, which tell us virtually nothing. Also, if you are buying a Maxtor, don't bother looking up actual transfer rates, as Maxtor is apparently afraid to release such information. Not to say Maxtor's are bad drives, actually Maxtor has risen torepparttar 107763 top in terms of technical support and they are much more willing to replace broken drives than some other companies, which is important since some ridiculously large amount (something like 10 or 15%) of hard drives are either dead on arrival or die withinrepparttar 107764 first few weeks of use. As withrepparttar 107765 last two points, when looking at transfer speeds (if you can find them) always try to pickrepparttar 107766 one withrepparttar 107767 highest numbers you can afford.

Notice thatrepparttar 107768 first three ofrepparttar 107769 4 major aspects were all speed related? That was done intentionally to give you a sense ofrepparttar 107770 importance of speed inrepparttar 107771 hard drive, because they are very very slow creatures, and for your gaming experience you don't need an enormous hard drive so much as a fast one. To increase speed substantially more you can set up a RAID, which is a network of hard drives which (in RAID0 mode) share portions ofrepparttar 107772 same data, such that accessing data takes 1/n time (n = number of hard drives attached) compared to 1 hard drive. To do this you really need a hardware RAID chipset, which are commonly included on higher-end mainboards.

Finally, capacity is an unnecessary nicety. The smallest hard drives you can buy today that are still within those higher speed classes are all about 30GB, which is more than enough for your games. But since games are not everything, and if you happen to be an iTunes member or like to download anime then you will really want some extra space. So I would recommend getting something between 60 and 120GB, any more and you're going to be paying through your teeth, any less and you might be looking to buy a supplementary hard drive in a couple years. And, oh yeah, 300GB hard drives from Maxtor are out, but they are comparatively slow, so I wouldn't recommend getting one for gaming, I like to stick to single platter drives (40-100GB usually), as they produce less heat and are less likely to break down on me.

That is really all you need to know in order to make a good choice when upgrading your hard drive or buying one for a new computer. Of course there are many other resources onrepparttar 107773 web if you would like more detail onrepparttar 107774 inner working of hard drives.

Turn offrepparttar PC,but do not unplug it,openrepparttar 107753 system unit. Setrepparttar 107754 multimeter to read DC volts inrepparttar 107755 next range higher than 12 volts.Locate a power connector similair torepparttar 107756 hard drive,or cdrom drive connector that is unused and turn onrepparttar 107757 PC.

You can also unplug a drive connector and use it as well.Turn onrepparttar 107758 PC and insertrepparttar 107759 BLACK probe intorepparttar 107760 power connector on one ofrepparttar 107761 BLACK wires.Touchrepparttar 107762 RED probe torepparttar 107763 YELLOW wire onrepparttar 107764 power connector.

The multimeter reading should be +12 volts Now touch repparttar 107765 RED probe torepparttar 107766 RED wire andrepparttar 107767 reading should be +5 volts.If no readings or different readings occured,you'll have to replacerepparttar 107768 power supply.Ifrepparttar 107769 readings were correct,you should checkrepparttar 107770 P8 or P9 connectors atrepparttar 107771 motherboard. These connectors may also be named P4 and P5.To check these connectors,performrepparttar 107772 following...

Insertrepparttar 107773 BLACK probe into P8 at one ofrepparttar 107774 BLACK wires. Insertrepparttar 107775 RED probe intorepparttar 107776 P8 connector atrepparttar 107777 RED wire. The reading onrepparttar 107778 multimeter should be +5 volts

Checkrepparttar 107779 power going torepparttar 107780 Motherboard connections by insertingrepparttar 107781 RED probe into P8 atrepparttar 107782 YELLOW wire and you should get +12 volts.Leaverepparttar 107783 BLACK wire touchingrepparttar 107784 black wire atrepparttar 107785 P8 connector.Checkrepparttar 107786 BLUE wire andrepparttar 107787 reading should be a -12 volts.

Now moverepparttar 107788 BLACK probe torepparttar 107789 BLACK wire onrepparttar 107790 P9 connector.Testrepparttar 107791 WHITE wire by insertingrepparttar 107792 RED probe and repparttar 107793 reading should be -5 volts.Checkrepparttar 107794 RED wires onrepparttar 107795 P9 connector and you should get +5 volts on each red wire.You won't get exactly 5 or 12 volts butrepparttar 107796 readings will be very close, such as 5.02 volts.

Ifrepparttar 107797 Power Supply is a couple of volts off,in either direction,such as whenrepparttar 107798 RED wire should be reading -5 volts but it reads -8 volts,or if there are no readings,replacerepparttar 107799 power supply.

DO NOT removerepparttar 107800 power supply fromrepparttar 107801 system unit case when performing these tests.DO NOT perform these tests if you do not feel comfortable.Be sure to remove any and all electrical static build-up from your clothes and body BEFORE touching any parts insiderepparttar 107802 system unit.And NEVER openrepparttar 107803 power supply case for any reason,since high voltage may be present.
