Description:

The shadow copies of volume F: were aborted because of a failed free space computation.

在32 bit作業系統中non-paged pool最大是256MB

There is a limitation with the 32 bit windows Server 2003 with volumes greater than 5 TB on which shadow copy is enabled (i.e on a single volume), a very basic chart is 1 TB of drive uses ~ 24MB of non-paged pool; so a 10tb drive would need 240mb

With 64-bits this isn’t an issue as the paged pool and non paged pool memory can grow to a maximum of 128GB

目前看來x86 OS的設計

目前可建議做法如下

1.重新安裝成x64版本

或是

2.將目前的F槽資料備份,磁碟分割成較小的size
