经过测试4G downsize 到 2G 可用。4G不能直接用。
How to downsize a 4GB compact flash card to 2gb
Instructions for reducing the partition size of a compact flash (CF) card:
- Open a command Window (Windows-> Start -> cmd)
- Type diskpart
A new window will open up with a “diskpart>” prompt - list disk
- select disk n (where n is the number of your CF card)
- list volume
- select volume n (where n is the number of CF card volume)
- clean all (this completely reformats the disk – it will take a while and appear to hang but be patient)
- create partition primary (this gives the newly formated CF card a partition so it can be resized)
- shrink querymax
This will tell you how much space is currently on available on your CF card. Subtract this from the filesize in MB you want for the final disk than add 1.
For my 4GB disk, shrink querymax returns:
“The maximum number of reclaimable bytes is: 3824MB”
I wanted a final disk size of 2GB which a google search told me is 1954MB so 3824 – 1954 + 1= 1871 - shrink desired = 1871 (This tells diskpart to try and shrink the disk by 1871 MB)
- Now that the disk is the right size, you can format the partition…
format fs=fat label=”volumelabel”
That’s all it takes.
