Disk Sanitization Service

Disk Sanitization Service


First of all the basics of the disk sanitization process helps you understand what Process involved during the sanitization process and after when it is complete.

The disk sanitization process uses three successive phases or user-specified byte overwrite patterns for up to seven cycles per operation. The random overwrite pattern is repeated in each cycle.

Depending on the disk capacity, the patterns, and the number of cycles, the process is time consuming. Sanitization process runs in the background. You can immediately start, stop, and display the status of the sanitization process.

The sanitization process contains two phases:

1. Formatting Phase

  • For capacity of HDDs (SATA, BSAS, FSAS, MSATA, or ATA) the formatting phase is skipped.
  • For performance of HDDs (SAS or FC), the formatting phase consists of a SCSI format operation.
  • For SSDs, the formatting phase consists of a SCSI sanitize operation.

2. Pattern Overwrite Phase

  • The specified overwrite patterns are repeated for the required number of cycles.

  • When the sanitization process is complete, the specified disks are in sanitized state. They are not returned to spare status automatically. We can make the sanitized disks to the spare pool before the newly sanitized disks are available to be added to another aggregate.

    We provide secure solutions to data wiping & degassing services for complete data erasure at the end of hard disk life cycle.So that no one can misuse your data.
