CautionĪlways back up your software before you run a low-level format or secure erase. If the Intel SSD is the boot drive, a fresh installation of the operating system is recommended after the low-level format or secure erase. Keep in mind that a low-level format or secure erase will remove all data contained on the Intel SSD.
If there are suspected issues with data integrity on the Intel SSD. 
If errors seen during a regular format/initialization or partition on the Intel SSD. If failures seen during read or write diagnostics. If errors seen during installation of an operating system. If the operating system experiences slowness or freezing. Refer to the following message from Ubuntu's mailing list if you want to learn more.The following are some possible problem scenarios when you run a low-level format or secure erase on the Intel® Solid State Drive (Intel® SSD): Warning: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes.Īll these warnings are safe to ignore, and your drive should be able to boot without any problems. Try making a fresh table, and using Parted's rescue feature to recover partitions. Is this a GPT partition table? Both the primary and backup GPT tables are corrupt. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Perhaps it was corrupted - possibly by a program that doesn't understand GPT partition tables. However, it does not have a valid fake msdos partition table, as it should. dev/xxx contains GPT signatures, indicating that it has a GPT table. Ubuntu images (and potentially some other related GNU/Linux distributions) have a peculiar format that allows the image to boot without any further modification from both CDs and USB drives.Ī consequence of this enhancement is that some programs, like parted get confused about the drive's format and partition table, printing warnings such as:
