How to delete "System Volume Information" folder from external drives?

"Use

RMDIR /s /q

This is for removing a directory in Windows 7. It's the same as DELTREE in DOS."

"The Solution I found to work - after trying innumerable numbers of commands- was this (from the linked Forum):

there's a simple way to do so : (the quotation marks are NOT needed,
except if specified before)

considering you have Total Control on the folder ""System Volume
Information"" :

Step 1 : click on ""Start"" type ""run"" and press Enter
(or step 1 :Win+R)

step 2 : in the command prompt window called ""Run"" type ""cmd"" and
press Enter

Step 3 : type the drive letter and a semicolon and press Enter (eg:
""I:"" and press enter)

Step 4 : the quotation marks are needed for this step type : rmdir

"I found a folder on my drives called System Volume Information which took up 280 GB of disk space and i could not delete the contents of this folder.
Even when taking ownership of the folder or trying to delete via Administrator Command Prompt, it didn't work.
Not even with the method directly mentioned above via Sevenforums.com, Unlocker didn't work either.
I had system recovery disabled because the certainty of having system recovery points was uncertain,
as they disappeared on a regular basis even though enough disk space was allocated.
What i did was, i connected the drive to another PC ( in my case HP Pavilion with Windows XP ),
opened the System Volume Information folder on the drive and noticed that there was only 2 mb data in there.
I also have to mention that System Restore was enabled on the Windows XP PC.
After connecting the drive back to my Windows 8 PC the System Volume Information folder contained approximately 2 mb data,
and freed up 280 GB data on the disk.
I also did this with other external disks and every time the System Volume Information folder shrunk to just a few mb.
Hopefully this information can help others with the same problem."
