Windows 7: Purpose of Local Drive (partition) on GUID Drive - Do I need it?

Purpose of Local Drive (partition) on GUID Drive - Do I need it?

I have a home built PC about 4 years old running Windows 7 64bit

My boot drive (C) has always been a SSD drive and my system is running fine.

I had a hard drive failure about 30 days ago, that corrupted my boot drive when it failed.

I have recovered from backup using Shadow Protect Desktop and a Bare Metal recovery

I am in the process of replacing my older drives that are out of warranty so I don't have any further issues.

All of the new drives are either 3TB or 4TB. I am formatting them as GUID drives and so far have had no problems.

My question is what is the purpose of the Local Disk partition that I see on each of my drives. Is it necessary and why would a drive have two local drives. I have one 4 TB Drive (Seagate Hybrid) that has a 128 MB Partition and a 100 MB Partition (both say Local Drive) plus the active partition of 3725.7, formatted NTFS.

Not a hugh issue, but I wanted to know if it could create any problems or prevent them in the future.

The 128MB partition is an MSR - Microsoft System Reserved - partition.

For an explanation please see my post here Weird hard drive partitions

I still do not know what is that 100MB partition and wherefrom it came.

Take a 4TB drive. Using Partition Wizard, delete all the partitions including the 128MB and 100 MB partitions and then format it again as a GPT drive.

After format completion, post a screenshot of the drive as it appears in Partition Wizard.

Hi all; Maybe this's just a simple question for experts in storage sharing. Why are SAN drives recognized as local drive while NAS drives aren't? I knew that SAN uses block level transfer to transfer data while NAS uses file level transfer. Does this has anything to do with why SAN drives and...
