rel="noopener" target="_blank" href="https://www.r-studio.com/Unformat_Help/diskimages.html">Linear imaging:</a></b> The drive is read from beginning to end by large blocks of disk sectors. When even one sector in the block appears bad, the entire block is treated as bad and either discarded or read sector-by-sector with significant loss of speed. The entire disk is imaged as a result. It's also possible to scan the drive during its imaging.</li> <li><b><a rel="noopener" target="_blank" href="https://www.r-studio.com/runtime-drive-imaging.html">Runtime imaging:</a></b> R-Studio Technician writes data obtained from the source object to the target object in parallel to other actions, including the opening of partitions, disk scanning, etc. All further access to the read data is performed from the target object. Only the necessary disk areas are imaged as a result.</li> <li><b><a rel="noopener" target="_blank" href="https://www.r-studio.com/Multipass-imaging-damaged-drives.html">Multi-pass imaging:</a></b> The data is read in several phases while trying to process good sectors first and saving the slow or <a rel="noopener" target="_blank" href="https://www.r-studio.com/What-are-Bad-Sectors.html">bad sectors</a> for later. The maximum amount of good data is imaged as a result. If there are no bad sectors on the disk, it works like linear imaging. Drive scan is also possible during this imaging.</li> </ul> <p class="text"> The following Table presents the advantages and disadvantages of these imaging types and our recommendations. </p> <table style="border: medium none ; border-collapse: collapse;" border="1" cellpadding="5" cellspacing="0"> <tr> <td style="border:solid windowtext 1.0pt" valign="top"> </td> <td style="border:solid windowtext 1.0pt" valign="top"> Linear </td> <td style="border:solid windowtext 1.0pt" valign="top"> Runtime </td> <td style="border:solid windowtext 1.0pt" valign="top"> Multi-pass </td> </tr> <tr> <td style="border:solid windowtext 1.0pt" valign="top"> Advantages </td> <td style="border:solid windowtext 1.0pt" valign="top"> Fast for healthy drives.

May get stuck on large bad block areas. </td> <td style="border:solid windowtext 1.0pt" valign="top"> Images are incomplete. </td> <td style="border:solid windowtext 1.0pt" valign="top"> Slow for faulty drives.
