The Dell Diagnostic partition is a feature that comes pre-installed on some Dell computers and contains tools for diagnosing hardware issues. It is not necessary for the normal operation of the computer, but it can be useful in identifying and fixing hardware problems. If you need to replace the SSD drive on your Dell Precision workstation, you may lose the Dell Diagnostic partition that was on the old drive. However, this should not affect the normal operation of your computer. If you do need the Dell Diagnostic partition, you can try creating a recovery USB drive using the Dell OS Recovery Tool. This tool allows you to create a bootable USB drive that can be used to restore your computer to its factory settings, including the Dell Diagnostic partition. Alternatively, you can try using the Dell SupportAssist tool, which is available for download on the Dell website. This tool can diagnose hardware issues and suggest solutions, and does not require the Dell Diagnostic partition to be present on your computer. Ultimately, whether or not you need the Dell Diagnostic partition depends on your specific needs and use case. If you are not sure, it may be worth keeping a backup of the partition just in case, but for most users, it is not essential.
I have a 3570 Precision workstation running Ubuntu.  I need to replace the SSD drive with a new drive.  I was told that the Dell Diagnostic partition on the current drive would be lost and I would need to reinstall it. All I can find is very old discussions about the Dell Diagnostic partition (newest is 2011). Also, the Dell site states if you do not have it on the drive, too bad, you cannot activate it. Do I need to worry about this partition? I have found some recreation instructs based on CDs but this information is so out of date. Does anyone know how to install, or update the SSD and still have the Dell Diagnostic partition on the drive? I have never used it.  Do I need it?
