Hard Drive And CD Drive Sharing The Same Bus?


A disk always has two passwords: A User password and a Master password. Even with older adapters without independent timing, this effect applies only to the data transfer phase of a read or write operation. Different computers come with different kinds and number of slots. SF 15, or the Fair Repair bill, guarantees our right to repair digital equipment like computers, refrigerators, cell phones and tractors. navigate here

Even today, hundreds of millions of PCs have ATA hard drives. The mode that a drive must use is often set by a jumper setting on the drive itself, which must be manually set to master or slave. x86 BIOS size limitations[edit] See also: Enhanced BIOS Initially, the size of an ATA drive was stored in the system x86 BIOS using a type number (1 through 45) that predefined HELP?! check it out

Hard Drive Interface Types

For example, ATA-4 supported Ultra DMA modes 0 through 2, the latter providing a maximum transfer rate of 33 megabytes per second. That is why someone put in a SCSI controller, and you are now putting in an IDE controller.As Jeff and others have suggested, once you get some confidence that things are Removal of a suitable optical device from within a sealed laptop (one with no facility to eject the device) will depend on the computer and the manufacturer’s specification. Find out who represents you in the Nebraska legislature.

RAID 1¶ RAID 1, also called disk mirroring, duplicates all writes to two or more physical disk drives. Pin 28 is not connected between the interface and the second drive position (the end connector on the cable). There is an effect, but the debate is confused by the blurring of two quite different causes, called here "Lowest speed" and "One operation at a time". "Lowest speed"[edit] It is Which Hard Drive Specification Has The Fastest Theoretical Bus Speed? The name PCMCIA comes from the group who developed the standard: Personal Computer Memory Card International Association.

what are the consecuences ?? There are two versions of SATA currently available: SATA/150¶ SATA/150 (also called SATA150) defines the first generation of SATA interfaces and devices. phoenix.com. http://www.tomshardware.com/answers/id-2772126/harddrive-bus-dvd-drive.html When your tractor breaks or your cell phone stops working, they want to be the only people who can fix it.

The downside of JBOD is that failure of any drive renders the entire array inaccessible. External Hard Drive Interfaces The optical drive negotiated for a lower speed but can handle faster on the bus. Byvexplorer Nov 15, 2008 hey all. If you agree with us, find out who represents you in the Massachusetts legislature.

What Technology Standard Is Commonly Used Today For Hard Drives To Interface With The Motherboard

Under ARMD-HDD, an ARMD device appears to the BIOS and the operating system as a hard drive. https://discussions.apple.com/thread/2344185?tstart=0 When these have been removed, attach the new drive cover – this will be narrower and designed to work with the housing. Hard Drive Interface Types Other convient features include providing power to low-consumption devices without the need for an external power supply and allowing many devices to be used without requiring manufacturer specific, individual device drivers Types Of Drive Interfaces Should my husband's business pay my business?

Only those of us with an eye for a trend, knowledge of Microsoft’s habit of borrowing ideas from Apple and recognition of the general move towards digital distribution might have seen check over here If it is the master on a channel that also has a slave installed, connect both the master and slave present jumpers. Instead, pin 34 of the host is grounded. It was eventually determined that these size limitations could be overridden with a tiny program loaded at startup from a hard drive's boot sector. Laptop Hard Drive Connector Types

They need to be firmly tightened, but keep an eye on the case for any signs of distortion or crystallisation of the plastic, and slacken the screws if you see this. It was first introduced with interfaces specific to certain CD-ROM drives such as Mitsumi, Sony or Panasonic drives,[11] and it was common to find early sound cards with two or three The Information for Your Computer Questions. http://vgvinc.com/hard-drive/hard-drive-noises-on-a-new-hard-drive.php Stevens; Paul J.

It requires manufacturers to provide owners and independent repair shops with access to repair information and replacement parts—so you have the resources you need to fix things quickly and affordably. What Type Of Expansion Slot Requires Extra Power So That 4 More Pins A video card also has a RAMDAC (Random Access Memory Digital-to-Analog Converter) which takes responsibility for turning the digital signals produced by the computer processor into an analog signal which can But if the hard drive in question is also expected to provide good throughput for other tasks at the same time, it probably should not be on the same cable as

Figure 7-5 shows an SATA data cable on the left and, for comparison, a UDMA ATA cable on the right.

They include a graphics processing unit (GPU) which is a dedicated microprocessor optimized for 3D graphics rendering. It may take half an hour or more, depending on the size of the disk. (Word 89 in the IDENTIFY response indicates how long the operation will take.)

Types Of Hard Drive Connections With Pictures Most disks support a Master Password Revision Code.

The SCSI commands and responses are embedded in "packets" (hence "ATA Packet Interface") for transmission on the ATA cable. tomshardware.com. For instance, as pictured above, there is often a locking screw that needs to be removed before the drive can be ejected. http://vgvinc.com/hard-drive/is-it-hard-to-just-replace-a-sata-hard-drive.php We also mentioned within that article that it is relatively simple to convert a laptop DVD drive into an external optical drive by way of an alternative.

A modern PC uses one or both of the following interfaces: Types of computer bus interfaces¶ Serial ATA (SATA)¶ Serial ATA (SATA) is a newer technology that is replacing ATA. Login now. Flash drives are usually USB ones either in the form USB sticks or very small, portable devices. Storage capacities range from 64MB to 32GB or more.

For the best preparation, find the technical guide for your laptop to confirm the correct procedure. The Serial ATA standard has supported native command queueing (NCQ) since its first release, but it is an optional feature for both host adapters and target devices. On the black connector, sockets 28 and 34 are completely normal, so that pins 28 and 34 of the drive attached to the black connector will be connected to the cable. Kozierok (2001-04-17). "The PC Guide: SFF-8020 / ATA Packet Interface (ATAPI)".

To protect against accidental corruption or deletion of files or loss due to fire, flood, or theft, you still must back up your data.

"VelociRaptor Returns: 6Gb/s, 600GB, And 10,000 RPM". Conversely, because the same data can be read from either drive, an intelligent RAID 1 adapter may improve read performance slightly relative to a single drive by queuing read requests for

These devices are not eSATA-compliant. Operating system compatibility¶ SATA appears identical to PATA from the viewpoint of the operating system. CSEL was introduced as a means to simplify ATA configuration. Otherwise, replace it with a DMA-capable device.

Use an Old Laptop Drive Instead! Most do not support hot-plugging. The remaining connector(s) plug into storage devices, most commonly hard disk drives or optical drives. Originally ARMD caused the devices to appear as a sort of very large floppy drive, either the primary floppy drive device 00h or the secondary device 01h.

Tell them repair is good for the environment, good for consumers, and good for businesses. But you can connect any ATA or ATAPI drive to any ATA interface with assurance that it will function, albeit perhaps not optimally. Both DVD and HD need each their own SATA cable to be plugged into 2 separate SATA connectors in the motherboard. Does the European number for emergencies (112) really work in Germany?
