Does anyone think there is a problem with below partitioning? I haven't done it myself and I can see that partitions 0 & 4 are the same. I am having a hard time figuring out why it appears twice and what having 3 primary partitions mean. My hard drive is a 500GB HDD.

Partition ###  Type              Size     Offset
-------------  ----------------  -------  -------
Partition 1    Primary            500 MB  1024 KB
Partition 2    Primary            148 GB   501 MB
Partition 3    Primary            151 GB   148 GB
Partition 0    Extended           165 GB   300 GB
Partition 4    Logical            165 GB   300 GB

This is a standard for MBR partitioning scheme.

MBR scheme was originally limited to 4 partitions. This limitation turned out to be inconvenient, so a workaround was invented: you can turn one of 4 primary partitions into an extended partition. This partition can't contain data directly, but it can hold an unlimited number of logical disks.

You have three primary partitions and an extended partition containing a single logical disk, which takes up entire extended partition.

MBR is a bit dated and was since superseded by GPT, but if you don't need UEFI boot (see this question for a list of benefits) it's fine.
