I had to take out the HDDs from the NAS as i had some network connection problems, so I've put them in my computer to copy some files over while i was tinkering with my router.
That's when i discovered a strange thing.
I have 2 HDDs, one is a 2TB Western Digital Green, the other one is a 1TB Western Digital Green.
On both of them i have 4 partitions divided like this :
1st - 500Mb EXT3 (probably for the NAS software)
2nd - 500Mb SWAP
3rd - most of the drive as EXT3
4th - 1Gb unallocated space.
Now, the first 3 partitions I know what they are for (the first 2 are for the proper work of the NAS and the 3rd being the space "seen" by the user), what i don't get is why both of the drives had the 1Gb unallocated space.
I know it's not much, after all it's just 0.1% of the 1Tb drive and 0.05% of the 2Tb drive, I'm not exactly complaining, I'm just curious.
P.S. both HDDs where partitioned as "standard" partition, I'm not a big fan of the RAID and i make my own backups so i prefer to have 2 drives where i know what's on which drive.
P.S.2 i had another 2TB drive which died in the NAS (had it replaced under warranty) and it had the exact same partitions, didn't pay attention then.
