HDD may refer to:
A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device used for storing and retrieving digital information using one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. The platters are paired with magnetic heads arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile memory, retaining stored data even when powered off.
Introduced by IBM in 1956, HDDs became the dominant secondary storage device for general-purpose computers by the early 1960s. Continuously improved, HDDs have maintained this position into the modern era of servers and personal computers. More than 200 companies have produced HDD units, though most current units are manufactured by Seagate, Toshiba and Western Digital. As of 2015, HDD production (exabytes per year) and areal density are growing, although unit shipments are declining.
Directional boring, commonly called horizontal directional drilling or HDD, is a steerable trenchless method of installing underground pipe, conduit, or cable in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. Directional boring is used when trenching or excavating is not practical. It is suitable for a variety of soil conditions and jobs including road, landscape and river crossings. Installation lengths up to 2000 m have been completed, and diameters up to 1200 mm have been installed in shorter runs. Pipe can be made of materials such as PVC, polyethylene, polypropylene, Ductile iron, and steel as long as it can be pulled through the drilled hole. Directional boring is not practical if there are voids in the rock or incomplete layers of rock. The best material is solid rock or sedimentary material. Soils with cobble stone are not recommended. There are different types of heads used in the pilot-hole process, and they depend on the geological material.
Directional drilling (or slant drilling) is the practice of drilling non-vertical wells. It can be broken down into three main groups: oilfield directional drilling, utility installation directional drilling (horizontal directional drilling), directional boring, and surface in seam (SIS), which horizontally intersects a vertical well target to extract coal bed methane.
Many prerequisites enabled this suite of technologies to become productive. Probably, the first requirement was the realization that oil wells, or water wells, are not necessarily vertical. This realization was quite slow, and did not really grasp the attention of the oil industry until the late 1920s when there were several lawsuits alleging that wells drilled from a rig on one property had crossed the boundary and were penetrating a reservoir on an adjacent property. Initially, proxy evidence such as production changes in other wells was accepted, but such cases fueled the development of small diameter tools capable of surveying wells during drilling. Horizontal directional drill rigs are developing towards large-scale, micro-miniaturization, mechanical automation, hard stratum working, exceeding length and depth oriented monitored drilling.

In today video I am going to share three awesome ideas about what can be made from an old HDD at home. All too often people are used to getting rid of old staffs, not thinking that they can be given a second life. An old hard disk drive can be useful as a fossil)) I mean if you take it to pieces, you can find lots of useful such as expensive and powerful neodymium magnets, rustless steel washers, nuts and so on. All of that will one day be useful for your DIYs. My piece of advice to you is to hold back getting rid of old staffs because one day you may need it. Along with that it doesn't cry and ask for food. That's why put it into a box untill better times. FB: https://www.facebook.com/romanursuhack INSTAGRAM: https://instagram.com/romanursu Main channel: http://www.youtube.com/user/ro...

Trenchless technology is a type of subsurface construction work that requires few trenches or no continuous trenches. It is a rapidly growing sector of the construction and civil engineering industry. It can be defined as "a family of methods, materials, and equipment capable of being used for the installation of new or replacement or rehabilitation of existing underground infrastructure with minimal disruption to surface traffic, business, and other activities."

Does your hard drive make a buzzing noise when you turn it on? Or does it make clicking noises or not spin up? Well, in this video I will show you how to fix this fairly common problem which is caused by the drive's heads getting stuck on the platters. You'll definitely need this before starting: http://amzn.to/2mO5DRB In some cases, data recovery software may have to be used. Here is a good one to check out: Stellar Phoenix Windows Data Recovery - Professional http://bit.do/stellarphoenix Want to be extra safe? You can build a clean air enclosure. Here's a video all about that: www.youtube.com/watch?v=xPEa0Wc9iUc
This is how you tell if your harddrive is dead or on it's deathbed. Also Linus walks through what to avoid in order to prolong the life of your hard drive. Finally, we suggest that users use SMART in order to test and keep up to date on the status of their drives. HD Sentinel is a great way to keep track of this automatically and it can warn you when something is wrong, or about to go wrong. It can even give you an estimated lifespan remaining on your drive, listed in number of days.

If your hard drive or a computer is beeping, it may have heads stuck on a platter. Just take it apart and move heads off the platter. Drive will work again and you can recover your precious stuff from it FOR FREE! Carefully turn the Disk platters in the normal spin direction and move heads carefully out and into park position. No clean room necessary, no special tools. I get one question asked a lot: What is the USB SATA board and where can it be purchased?

How much faster can a new HDD make your games load? Tonight on GHGtv, we aim to find out. Tonight's testing is simple. We are putting a 5 year old WD Caviar Blue up with over 400GB of stuff on it up against a Brand New WD Black that manufactured in June this year. The results are impressive. We test load times in: GTA V, Fallout 4, Doom and Left 4 Dead 2. Why did I go Western Digital? ( I am in no way sponsored ) I trust their drives everyday, and they are yet to let me down. I hope you'll enjoy tonights show, I am certainly enjoying my new hard drive. ---- GHGtv ep44
Simple operations performed by a hard drive with no cover, so that you can see what it looks like inside. This experiment was performed on an old hard drive, DO NOT try this with newer expensive hard drives, it is a bit risky. Details & Specifications ■ Model of drive: Samsung WU32543A 2.5GB ■ Test performed in Windows XP ■ Disk died about three months after being opened Joshua Marius www.letheonline.net

[Chorus: Lil' Mo]
Kissed the girls, made them cry
Thuggin life, and gettin high
Why you gangsta, all the time?
That's a thug's nature
Though sometimes, I can deal with it
I realize, that I'm feelin it
It's a love and hate relationship
but that's a thug's nature
[add to line four of Chorus first time:] "That's a nigga nature"
[2Pac]
I'm probably too nice at first, I let you kiss me where it hurts
Me and you gettin busy, slingin dick in the dirt
Met you at a pool party it was cool to kick it
See us, tounge-kissin, you was truly with it
Little ecstacy, Hennesey, mix with me
Picture me pay for pussy when the dick's for free
Hey now, where my niggaz at? Tell these hoes
Before I pay; I jerk off, word to Moses
Visions of you sittin there sweaty and wet
Pointin to the places that you want me to hit
Give me room all up in the womb, call the cops
Nigga, hittin walls 'til them bastard drop
Label me Makaveli - thug nigga with bite
Livin life like a rock star's Friday night
Make money, get pussy, always keep a pager
Cell phone in the ride to complete my nature now!
[Chorus]
[2Pac]
Haha.. started as a seed from the semen; straight outta papa's nuts
Lustin for creamin - bitches with big butts
Curves make a nigga cry, tits and shit
When I'm locked down beggin you for porno flicks
Sneak weed in, help a nigga pass the time
Put my name tattoo'd so that ass is mine
Tell everybody; 'Pac put it down for good
A local legend through the whole hood, follow me
I got a gun on me, goin for none on the run baby
You know a nigga need some, is my son crazy?

Picture a nigga in heaven, high off weed I fly
Got me missin dead homies wishin phonies would die
