WipeOS current limitations

List of WipeOS current limitations

  1. TCG locked drives:
    • TCG locked drives cannot be verified. Depending on how they are locked, we will either not let the user start the verify (because the drive is not readable), or the verify will fail when it gets to sectors it cannot read. Drives should be unlocked before attempting to verify them
  2. Drive hidden areas:
    • We support restoring hidden areas on SATA drives. These are Host Protected Area (HPA), Accessible Max Address, and Device Configuration Overlay (DCO) which are all the options listed in the SATA spec. We do not handle proprietary or vendor specific hidden areas (nor do we check for them).
    • For NVMe drives, we support only drives with a single attached namespace. We do not check for detached namespaces, multiple namespaces per controller, or shared namespaces.
  3. Drive firmware logs:
    • We only examine the pattern on the drive when we verify, and we do not look at any firmware logs.
    • We do not support verifying wipes that leave random bytes on the drive. This includes wipes like a NIST Random wipe and (some) cryptographic purge methods. Drives wiped this way will fail our verify with an error of "No pattern found". This does not say that they were or were not wiped, only that we cannot verify if they were wiped.
