DeepSpar Disk Imager

DeepSpar Disk Imager is a professional hardware/software data recovery solution for imaging hard disks that have serious media corruption, bad sectors, unstable and degrading heads and other problems. DeepSpar Disk Imager was developed by DeepSpar Data Recovery Systems and was first released in November 2006.

Features

DeepSpar Disk Imager claims to have the following features

  • Maximum imaging speed for modern drives in UDMA mode up to 75 MB/second (4.5 GB/minute, 270 GB/hour).
  • Drive-to-drive imaging bypassing BIOS and operating system. DeepSpar Disk Imager works directly with the drive on the lowest register level preventing any interference from BIOS, OS and other hardware and software.
  • Configuration, sector map and logs are stored on destination drive. This allows imaging to be interrupted at any time with no data loss. Also it makes configuration, sector map and logs accessible using DeepSpar Image Viewer and other software for analyzing.
  • Control of sector read timeout. If sector or group of sectors takes more than specified amount of time to read DeepSpar Disk Imager instructs the drive to skip this sector immediately with Hardware or Software reset to process it afterwards on subsequent passes. This allows more gentle handling of bad areas and speeds up the imaging process.
  • Turn off auto-relocation (G-list mapping) and SMART operations. Special vendor-specific ATA commands are used that pre-configure the hard drive for imaging, reduce the number of read operations and the intensity of the operations, which cause disk degradation.
  • Data evaluation on the fly. Real-time reporting gives user a window on the type and quality of data you're imaging - while the process is still underway. You can even see the number and type of files or OS structure elements imaged so far.
  • Read ignoring error correcting code. Read bad sectors as raw data with Read Long ATA command. Each sector is read specified number of times and resulting sector is statistically calculated based on these readings. This is especially effective on degrading hard drives with unstable reading.
  • Multi-pass imaging. Apply different algorithms to effectively retrieve data from bad sectors of partially failed hard drives in multiple passes.
  • Ability to repower the drive. Hardware automatically repowers drives that become unresponsive to continue imaging process without rebooting the whole system.
  • Create or reset Host Protected Area (HPA) both on Source and Destination drives.
