Data Recovery Glossary (Letter R)

RLL (Run Length Limited)
An encoding scheme used during write operations to facilitate data readback.

ROM (Read Only Memory)
Integrated circuit memory chip containing programs and data that the computer or host can read but cannot modify. The computer can read instructions out of ROM, but cannot store data in ROM.

RPM (Revolutions per Minute)
Rotational speed of the media (disk), also known as the spindle speed. Hard drives typically spin at one constant speed. The slower the RPM, the higher the mechanical latencies. Disk RPM is a critical component of hard drive performance because it directly impacts the rotational latency.

Radial Path
The straight-line path from the center of the disk to the outer edge of the disk.

Random Access Memory (RAM)
Memory that allows any storage location to be accessed randomly, as opposed to tape drives, which are sequential access devices.

Read Channel
Performs the data encoding and conversions the drive needs to write computer generated information onto a magnetic medium and then read that information back with a high degree of accuracy.

Read Verify
A data accuracy check performed by having the disk read data to the controller, which in turn checks for errors but does not pass the data on to the system.

Read/Write Head
See Head.

Recoverable Error
A read error that the drive can correct by ECC recovery or by re-reading the data.

Redundant Arrays of Independent Disks (RAID)
Groupings of hard drives in a single system to provide greater performance and data integrity.

Rotational Latency
The amount of delay in obtaining information from a disk due to the rotation of the disk. For a disk rotating at 5200 RPM, the average rotational latency is 5.8 milliseconds. See also Mechanical Latency.

2 Ways To Backup Your Laptop Data

Backup Laptop Data Creating a backup of any Windows Vista computer, including a laptop, is a safety measure in case the hard drive fails. Backups can be accomplished using several options, but the most convenient way to save data is either on a network drive or by burning the files to a CD-ROM or DVD disk. These two methods create full backups that are easily retrieved after a hard drive failure.

Backup laptop data to a Network Drive

  • Right-click the “My Computer” on the desktop and select “Map Network Drive.” Select the drive letter in the drop-down box labeled “Drive.” In the text box labeled “Folder,” click the “Browse” button and select the location of the network computer and folder. Once you’ve entered the information, click the “Finish” button.
  • Double-click the “My Computer” icon on the desktop and you’ll see the newly mapped drive. Double-click this icon and an Explorer window opens. Leave this window open.
  • Double-click the “My Computer” icon again to open a second Explorer window. Navigate to a location of the files you wish to back up. Highlight these files with the mouse and drag and drop them to the opened Explorer window from step 2.
  • Continue copying files to the mapped drive until you’ve copied all the applications and documents. Close both Explorer windows when finished

Backup laptop data to a CD-ROM Disk

  • Insert a blank CD-ROM disk into the drive. Windows automatically opens a new dialog window. Select “Open writable CD directory using Explorer” from the options and click “OK.” You may need several CD-ROMs to backup your hard drive. If you use more than one CD-ROM, these steps need to be repeated.
  • Double-click the “My Computer” icon on the desktop. Navigate to the location of the files you wish to back up to the CD-ROM.
  • Highlight each file and drag and drop them to the opened Explorer window from step 1. Once you have copied all the files, click the “Write to CD” button.
  • Wait a few minutes while the CD-ROM burner copies the files to the CD-ROM. This may take several minutes. You know when the process is complete when the CD-ROM drive door opens. Remove the CD-ROM backup and store it in a safe place.

Happy To Have Them! I would like to give my heartfelt thanks to the people at Computer Based Associates. Frankly I am an IT manager but I even did not backup my home computer. Suddenly, my 500 GB Western Digital hard drive did not spin up any more. I lost everything that was important to me. One of my co-workers gave me the phone number for them since he got data recovered there from a smoking hard drive. They fixed the hard drive, I don’t know how they did it, and got all my data. They have their own clean room and facility instead of sending hard drives to other locations.
