M5-481---questions about hard drive partitions.

lithp — Wed, 25 Sep 2013 00:21:34 GMT

I accidentally overwrote my boot sector when installing Ubuntu a few months ago. Just recently I ran the factory reset. Everything's working fine, but looking at my drive partitions has raised some questions.

1. At the end, I have a 16.5 GB recovery partition. All well and good. However, I also have a 400 MB "recovery partition" at the very beginning of the drive. This seems odd to me, as a) I already have a recovery partition, b) 400MB seems very small, and c) as far as I know, Microsoft wants the EFI partition (300MB, also present on the disk) to be first on the drive.

So---should it be there? What's it for? If anyone doesn't know, but has a machine the partitions of which haven't tampered with, I'd love it if you could open "Disk Management," take a screenshot, and post it here.

2. I noticed that I have TWO drives, one of which is about 18.5 GB and an SSD. What is on this drive? Can I safely format it and expose it to Windows? EDIT: The SSD is apparently used for fast booting.

I have deleted all partitions from my 120GB M5 but I did make a note before I removed them:

A: 400MB Recovery Partition

B: 100MB EFI Partition

C: 100.63GB NTFS Partition

D: 18.00GB Recovery Partition

It is also possible that other partitions could exist that are not visible to Windows.

Yes, the SSD is cache and I don't believe it can be used for data.
