What happens when you delete a file? It depends on the storage media…
Subscriber Richard Fuller wrote this week with a problem.
I’ve discovered that deleting files from my DVD drive does not send them to the Recycle Bin. Is this normal behaviour for XP SP3? And is there any way to change it so that deleted files do not disappear from the system without the opportunity to restore them easily?
I see, too, that the DOS command Undelete of earlier versions of Windows is not recognised by XP. Is there an XP version of that utility masquerading under a different name, perhaps?
With continuing thanks for your outstanding service,
I wrote back to Richard to tell him that, unfortunately, the Recycle Bin doesn’t apply to removable storage, whether it’s a flash drive, CD, DVD. External drives, on the other hand, will make use of the Recycle Bin (at least, in Windows 7 they do).
A DVD is not a hard drive. Data is stored in a different manner – it’s actually burned into the medium between the two clear sides of the disk. A hard drive has magnetic platters and stores data by magnetizing and demagnetizing small parts of the drive to represent 0’s and 1’s. Re-using a hard drive is as easy as remagnetizing the spot. Deleting a file from a DVD, burns a part of the DVD to indicate that the file is gone (it doesn’t actually wipe/rewrite the file to burn it away, though).
CD’s and DVD’s are use-once items. The CD-RW and DVD-RW (whether + or – versions) are made in a special manner that enables them to breally use once, then completely wipe, then use again.
I’m puzzled as to why you might even consider deleting files from a DVD.
If you’re writing files to a DVD, I strongly recommend writing all files to the DVD at one time. Even though the drive manufacturers and software manufacturers enable “multi-session” burning to a DVD, think about the possibility of a power blip or computer crash — or disk-burning software crash — just as you’re writing something important like the file pointers on the drive. I’d hate to lose everything I’d already written to a DVD just because I’d been trying to write one more thing on it.
I’m pessimistic about using DVD’s and CD’s for multi-session. I’ve seen too many CD’s and DVD’s turned into coasters by CD-burning programs to trust writing to the same DVD or CD multiple times.
