What color or stripe down one side of a cable marks this side of the cable as pin 1?
Usually an arrow pointing to it, or a number 1 on the connector. It's also on the side with the red wire. And most boards are keyed with a slot on the side of the female part, and extrusion on the male connector... so it can only be inserted the proper way.

How do you remove Toshiba satellite m200 hard drive?
ok here's the deal, i want you to know that removing the harddrive from a laptop is not the best thing to do. you can injure the computer or the HD it's self. But if you want to know, on the side of the computer there should be the batery, and other ports, now there will be a piece of the computer that looks like it can be pulled out, it can be. however, you must first unscrew it from the motherboard. it is very easy to do this, simply turn the laptop over and look for a screw that looks like it was holding it in, unscrew it and turn the laptop back over again. now, usually the HD is on the opposite side of the computer as the battery. when the screw is out and you are sure you have it, give the piece a good pull. with a few good tuggs it should come out.
AnswerReplacing the hard drive in a Toshiba 1625 is very easy to do, and no more risky to your computer than dropping in a memory chip. It should take less than 5 minutes. On the bottom of the 1625 are three screws with the letter K embossed next to them - those are 3 of 7 screws that hold the keyboard in place, The other four screws are accesed by snapping off (no screws) the narrow ridge of plastic spanning the screen hinges - it's the piece with the 7 little leds and icons. Yes, it really does snap off (swing the screen way back). Remove the other 4 screws and lift the keyboard out. The hard drive is the 10x7cm box you see in the middle. Removing the two screws on the right side will enable you to lift (using the plastic tab) that end of the harddrive up just to the level that you can slide it out to the right (the HD socket is at the other end). DON'T ATTEMPT TO LIFT IT STRAIGHT OUT - IT HAS TO BE UNPLUGGED FROM THE SOCKET BY PULLING TO THE RIGHT. You may have to rock it back and forth while pulling. When installing a new hard drive, you'll obviously do the reverse, but be careful to hold the drive up with one hand as you plug it in so you can lower it gently into place.How can a Mac remove a partition on external hard drive?
Built into Mac OS X is an application called Disk Utility, which can format and partition any internal or external volume. It's located in /Applications/Utilities/. Additionally, there are some third-party utilities that can work with partitions on-the-fly: iPartition, DiskWorks, and VolumeWorks all claim to do this.
This depends on your expertise and preference. Typically I suggest setting your optical media drive (CD/DVD/ETC) as your first boot device, but this tends to slow down your boot time ever so slightly as the drive seeks in order to figure out if the disk in the drive is bootable media or if there's even a disk in the drive. It makes installing boot-level media far easier, however.
If you know what you're doing and know how to manually open the boot menu without going into setup, then set your hard disk as your first boot device, followed by your optical media drive, then finally any other medium such as floppy drive, removable media, etc.
How do you resize a partition?
You have two ways to resize a partition:
1. Use the built-in Disk Manager in Windows7/XP. However, with it's help, you can only increase your system partition e.g. Drive C:, but can't shrink the size of partitions.
2. Use a third-part software. I recommend all the users of Windows OS to download a third-part freeware for managing your hard drive. An excellent partition assistant is suggested: Aomei partition assistant Home Edition. It's totally free and simple to use, you can read the guideline below to know more details about this partition magic.
---------------------------------------------------------------------------------------------
1. Resizing partition with the Partition Manager on Windows 7
You can resize directly to the desired size for your partition. Clink Resize.
At the opening of the window you can then indicate with precision the size of your new partition.
You can reduce the size quickly and change the partition size by dragging the double-headed arrow (circled in red). Then click OK.
Your hard drive will appear in two parts: A partition with operating system Windows 7 (in blue) and an Unallocated Partition (in gray).
To validate these changes simply click on Apply.
2. Create a partition with Partition Manager Assistant Home Edition 2.0 on Windows 7
Once you have completed the resizing your partition, create the partition so that Windows 7 will recognize it and can use it. This is the same to right click on the unallocated partition and click on Create.
Otherwise, you can also select the unallocated partition and click on Create.
In both cases, you will get this dialog box telling you the settings to create your partition.
In the partition label (partition name) enter a name easy to remember and easy identification. We chose to use the name of Disque_6GB. While this is optional, we recommend that you define then a letter to your reader. For our part we have chosen the letter E. It's your choice and identify that the letter of your future hard disk partition. Then click OK.
All parameters for the partition management are now complete. It remains only to apply for that Partition Assistant Home Edition 2.0 makes these changes and recognize them in Windows 7.
To validate these changes simply click on Apply.
3. Apply changes all partitions to take effect
Once you have clicked on Apply, you will confirm these changes by clicking on Proceed (Continue).
Note: In the Resizing Partition (partition resizing) in blue you have an instruction required reboot (restart required) which means you'll have to restart your computer for the changes being made. Save your open documents before you click on Proceed (Continue).
Then click Restart Now.
Windows 7 is going to restart.
At this stage it is always possible to undo the changes by clicking on any key on your keyboard. Otherwise, the partitioning assistant will launch after 8 seconds...
The changes are being ... Partition Assistant 2.0 Home Edition is currently conducting the required changes ... It will take time Partition Assistant Home Edition 2.0 transforming. Attention these ends, it is important to be patient and do not restart your computer until the process is not completed.
Conclusion
In this tutorial we saw how Windows 7 change a partition, the resize or shrink partition with application Partition Assistant Home Edition 2.0. It free provide for personal users or home users. The Partition Manager has the functions which the Windows "Disk Manager" doesn't have, such as resize system partition, extend/shrink partition and move partition. These cannot be handled via the Windows built-in partition manger, so the 3rd party partition software, Partition Assistant is needed to you. Yes, you will free enjoy all features of the partition manager.

How do you free up space on your hard drive?
You could try some of the following: - Deleting files you no longer need. - Uninstalling programs you no longer use. - Clearing your cache and deleting your cookies and temporary internet files. - Defragmenting your hard drive. - Emptying your recycle bin. - Reducing the size limit of your virtual RAM. - Removing any partitions on your hard drives.
Describe how hard drive store data?
The average Hard Drive uses magnetivity to turn tiny segments of a large plate to either magnetized, or demagnetized. Computer information is processed and stored as 1's and 0's, so magnetically, magnetized would be a 1 and demagnetized would be a 0. For example, an F in binary is 01000110. So, on a hard drive, 8 tiny switches would be set to "off, on, off, off, off, on, on, off" to store a single letter "F" (as well as more code to decide WHERE to store the letter f).
How many pins on a Sata hard Drive?
Parallel ATA connectors use a 40 pin female connector with one pin removed for keying.
Is software saved on a hard drive?
Normally, your software is saved on your hard drive once. It is either put on there by the original manufacturer or when you put on a new program. Updates are also saved on your hard drive. All your software is saved on your hard drive. Normally, nothing happens to this software when you use your computer. When you use it, you simply put a copy of what exists on your hard drive into your computer. When you are through with it, you erase the copy in your computer. Nothing happens to the copy on your hard drive. In the future, it is possible that programs will come over the internet and remain in the computer until it is turned off. A major company will soon have something like this available free. It has a word processor, spreadsheet, and database. The software and data will be stored over the internet. This answer is correct today. It might be wrong tomorrow.
What is the difference between Sata and ESata?
SATA and eSATA are electonically the same, but the construction of the cables and the terminals is different. The major difference between the two is that SATA is designed for use inside a computer system while eSATA is for use externally.
What is meant by low level formatting?
Low-level formatting is the process of outlining the positions of the tracks and sectors on the hard disk, and writing the control structures that define where the tracks and sectors are. This is often called a "true" formatting operation, because it really creates the physical format that defines where the data is stored on the disk. The first time that a low-level format ("LLF") is performed on a hard disk, the disk's platters start out empty. That's the last time the platters will be empty for the life of the drive. If an LLF is done on a disk with data on it already, the data is permanently erased (save heroic data recovery measures which are sometimes possible).
If you've explored other areas of this material describing hard disks, you have learned that modern hard disks are much more precisely designed and built, and much more complicated than older disks. Older disks had the same number of sectors per track, and did not use dedicated controllers. It was necessary for the external controller to do the low-level format, and quite easy to describe the geometry of the drive to the controller so it could do the LLF. Newer disks use many complex internal structures, including zoned bit recording to put more sectors on the outer tracks than the inner ones, and embedded servo data to control the head actuator. They also transparently map out bad sectors. Due to this complexity, all modern hard disks are low-level formatted at the factory for the life of the drive. There's no way for the PC to do an LLF on a modern IDE/ATA or SCSI hard disk, and there's no reason to try to do so.
Older drives needed to be re-low-level-formatted occasionally because of the thermal expansion problems associated with using stepper motor actuators. Over time, the tracks on the platters would move relative to where the heads expected them to be, and errors would result. These could be corrected by doing a low-level format, rewriting the tracks in the new positions that the stepper motor moved the heads to. This is totally unnecessary with modern voice-coil-actuated hard disks.
More input from FAQ Farmers:
- The only time you could low level format a new voice coil hard drive if it you would have bad sector that are not being taken care by the hard disk logic. Most of the time you will have a utility to do this task that comes from the manufacturer of the drive and it will not work with any other brand. Maxtor and late quantum has a utility called Max blast plus and power max and others. They are used to diagnostic but also to fix at the low level.
- Those utilities can many times restore an unstable drive by reformatting at the low level and blocking out bad sector. Of course if the RLL (magnetic data) is low because the read write hardware is defective it will do no good. If the surface was damaged it could give the drive a new life.
- There is also an application called Spinrite (by Steve Gibson) It's not a low level format in itself but it reads and rewrites the data (at the low level) while analyzing the disk. Spinrite is over 17 years old and has been updated to the new technology ever since version 1 (current version is 6). I's a very respected software by all the hard disk service technician around the world. Steeve Gibson is one (if not the best) of the best hard disk low level white hat hacker in the world.
- No software of any sort can truly low-level format today's modern drives. The ability to low-level format hard drives was lost back in the early 1990's when disc surfaces began incorporating factory written "embedded servo data". If you have a very old drive that can truly be low-level reformatted, SpinRite v5.0 will do that for you ( But this is only possible on very old non-servo based MFM and RLL drives with capacities up to a few hundred megabytes. You can still read and write from that "so called" low level but not in the same way it was original;y possible then with old drives.
Primary storage is volatile; meaning it cannot retain data values indefinitely. In other words, when power is turned off, all contents are lost.
Secondary storage is non-volatile.
What is the best hard drive available?
They have this hard drive now that's 10TB. it costs around 1,500 to 2,500 dollars for the different makes of it.
However, the largest single consumer HDD available in the U.S. (as of June 2010) is 2TB.
If a magnetic drive has four platters how many heads does it have?
Each platter on a hard drive has 2 heads.
Every Additional Platter you can multiply x2
Example:
1 Platter x 2 = 2 Heads
2 Platters x 2 = 4 Heads
3 Platters x 2 = 6 Heads
4 Platters x 2 = 8 Heads
5 Platters x 2 = 10 Heads
ETC...
At least until some new hard drive Architecture comes into place.
What does 2tb mean in a hard drive?
1TB stands for 1 terabyte which is 1,099,511,627,776, bytes (aprox 1100GB). Hard drive manufacturers use a different table corresponding 1TB to 1000GB which is just not true. So a 1TB hard drive usually gives you around 930Gbytes of storage capability.
How do you use a disk clean up?
Disk cleanup works on the basis that it is cleaning up old or unnecessary files. One of the sectors that it cleans is the temporary internet files. To do this, it simply goes to the temporary internet files folder that can be accessed from Microsoft internet explorer by clicking on tools - going to internet options. The next bit depends on the browser that you are using but after this click settings - view folders. This then brings up all of the temporary internet files and cookies. This is basically what disk cleanup is doing.
Unplug the power cord
A hard disk or hard drive is the place on the computer where files are magnetically written to. The disk uses a metal head to read, write, create, copy, move or delete files on the spinning disk. It is usually located at the front of the computer. Don't turn off your computer while the disk is doing anything. Otherwise, data could be damaged!
How much can you put on the xbox 360 20 GB hard drive?
that depends on the size of the files you put on the hard drive. 20 GB(gigabyte) is 20 thousand bytes, so if each file you put on your hard drive is 10mb(megabyte) you could fit 2,000 files. The smaller the file size the more you can fit on the hard drive.
*More Technical for the less brain dead: 1GB is 1024mb so realistically 20480mb is the actual Size of the Drive, however there is file structure allocation, there is firmware, and any preloaded software (Microsoft does have special software preloaded on the 360 hard drives) unfortunately the space taken up by those things is unknown to me, and as such I can't give you an accurate answer. ESTIMATED SPACE: 14GB or 14336mb of free space, and to go back to "10mb" per file... you could put 1433.6 files on that hard drive.
What is the primary hard drive letter?
Default drive letter for a hard drive is C
On my computer there were two hard drives installed, and the second was D
CD drive is E
USB ports are F, G, H, I, J, and K on mine
Why hard disk is a magnetic disk?
Common hard disks with read/write heads are magnetic storage.
The newer SSD (solid state drive) hard disks are not magnetic because there are no read/write heads. Solid state means no moving parts.
SSD drives are labeled as such so you know what you are buying.
Hich type of drive is installed in a 5.25-inch bay?
These bays contain CD Drives/Burners, or DVD Drives/Burners. Although Hard drivers typically go in one of your 3.5 bays, there are braces you can buy to fit one in a 5.25 bay. There are also some Audio pre-amps that can fit into these bays.
