You have the flexibility to do anything you want with the hard disk. What do you want to do with it? I don't prefer pre-installed systems of any sort because if I ever need to replace the drive or have a disaster I may want to re-install. I would rather know how the system was created. If I install it then I know I can re-created it. If it is pre-installed and there are special needs to it then I may never be able to admin it. Of course if they give you all of the special configuration information then that is good. And it is likely that they are selecting hardware which does not need any special configuration. That latter is always best. > It is a very high-end laptop, and God forbid that anything happens > to the SSD. No. If the SSD dies then simply replace it and restore from backup. Because backup is always a good idea regardless of the media. Backups save people from people mistakes. :-) > Every article I look up in my research says that you must be going > on a safari in your fstab and partitioning your SSD and HDD for > certain file directories. Most of those articles are quite old now. After a couple of years all of that special handle migrated into the partition tools. If you install using the debian-install from a netinst, CD#1, DVD#1 disk then the partitions will be set up correctly aligned. > In short, I hope what you're saying is right, but I need to see a > second opinion or a personal account that supports what you're > saying before I make any changes to my storage devices. Then let me give a second to Andrei's report. You should be fine. What Andrei said sounded completely reasonable to me. But it doesn't sound like you are needing to partition the SSD at all. You said it was the hard disk that wasn't partitioned. Therefore it would be the HDD that you would need to partition and use. And you said you did that already. Most new spinning hard disks are also coming with Advanced Format partitioning with 4k sectors. Basically it means that spinning hard disks have about the same issues with partition alignments as SSDs do. So you should check that the partitions are aligned with hard disks too these days. > My SSD specs are: > 120 GB Intel 525 Series mSATA SSD > And my HDD specs are: > 500 GB 7200 RPM SATA II Sure. Rather than very vague essays it would be better if you have a specific question to just ask it. For example you could post your partition table and ask if it were aligned. sfdisk -d /dev/sda Bob
