• Some SSDs and NVMes available on Apple machines do not implement any firmware-based erasure command. Therefore, these data storage devices cannot be purged but only cleared via normal overwriting methods.
  • The known models were this happens:
    • MacBook9,1 , MacBook8,1 , MacBookAir7,1 (all with NVMe drives)
    • MacBookPro11,1 (with OWC Aura SSD)
  • This appears to be an Apple customization. Since the commands are simply missing, there is nothing Blancco can do about it.
• On rare occasions, saving a report (normal report or issue report) on a USB stick can take longer than expected (up to several minutes). We suspect this problem is connected to the USB stick were the report is saved, feel free to replace the USB stick if you witness this problem. The report saving works in the end, so this is more of an annoyance.
• Some ATA SSDs that implement the Sanitize Crypto Erase command fail the erasure when handled with "Blancco SSD Erasure" if the verification percentage is below 100%.

  • This is a known issue that is going to be fixed in the 6.2.1 release coming before the end of October 2017.

  • There is a workaround: setting a verification percentage of 100% will prevent this from happening.

• Some ATA SSDs that implement the Secure Erase command fail the erasure when handled with "NIST 800-88 Clear" if the verification percentage is between 11% and 99%.

  • This is a known issue that is going to be fixed in the 6.2.1 release coming before the end of October 2017.

  • There is a workaround: setting either a verification percentage of 10% (or less) or equal to 100% will prevent this from happening.
