Drives

What are these drives and what are they used for? I'm looking into upgrading my motherboard and don't know if I'll need all of those drives then.

    WINRE is the Windows Recovery Environment. PBR isn't a standard drive, you will actually have to tell us, what it is used for. – Ramhound Feb 29 '16 at 14:23
  • @Ramhound All of these drives where installed when I bought my computer so I have no idea :/ – LukaxH Feb 29 '16 at 14:25
  • I did a simple google search on PBR_DRV its purpose is well documented. – Ramhound Feb 29 '16 at 14:29
  • It's worth mentioning those are partitions not physical drives. – qasdfdsaq Feb 29 '16 at 14:56

As Ramhound noted, WINRE_DRV is a partition for Windows Recovery Environment.

I suspect PBR_DRV is a partition associated with the Lenovo One-Key Recovery software. It may be other vendors also supply something based on the same third-party software.

Both of these are probably relatively small partitions that are normally hidden from end-users. You should probably leave them alone unless you have, and know how to use, a full set of DVD/CD media to reinstall your operating system, drivers and vendor-supplied utilities.

Neither of these need "optimization" or defragmenting.

  • Its Dell but close enough, it contains the factory image, for restoration purposes. – Ramhound Feb 29 '16 at 14:29
  • When I upgrade my motherboard should I install this disc or should use throw it away? – LukaxH Feb 29 '16 at 14:31
  • @Ramhound Accidently hit enter button :P – LukaxH Feb 29 '16 at 14:34
  • @LukaxH - Install what disk? Neither partition is required for Windows to function. – Ramhound Feb 29 '16 at 14:35
  • @Ramhound The pbr_drv one – LukaxH Feb 29 '16 at 14:35
