D Drive is Too Full

Dear Elizabeth,

I am runing Vista with 64 bit and intel processor.

I have a constant message that my D drive is full. I looked at it and it has a huge file called MediaID.bin in it. That is 14.9MG ad is taking up all the space.

What is it and what can I do to get rid of it?

It is safe to delete?

thank you, Louise


Dear Louise,

While you did not mention what brand of computer you are using, I feel that it is a pretty safe guess that they “D” drive is probably a recovery partition, only big enough for the system recovery files, and not meant to be used for any other purpose.

What is a recovery partition? It is a special section of your hard drive that is set aside with files that can recover your computer to its original factory condition if you ever need to.

A recovery partition is a good thing, but it can also give you a false sense of security.

Most computer manufacturers now build computers with this recovery partition instead of including recovery disks with the computer. This makes the computer less expensive to build. In an ideal world, you, the computer owner would use that recovery partition to create your own recovery disks, and then store those disks in a safe place.

If you have created those recovery disks, you will at least have them in the future should the need arise.

If you don’t create recovery disks, you still have the recovery partition to restore from UNLESS your hard drive dies. Since the recovery partition is located on your hard drive, if it goes, you lose not only your operating system and files, but also the ability to restore. You would at that point have to purchase not only a new hard drive, but quite possibly a new Windows disk.

You asked if it was safe to delete. Yes, it is probably safe to delete the files, but I don’t think it is a good idea. Even if you have created recovery disks, I still prefer to have that extra insurance in the event of a system crash or malware infection.

    My MSI laptop Vista keeps sending me messages my C drive is too full. I moved everything I knew was safe to drive D. I was able to free up a few things but I rarely use that laptop. The other laptop I do use all the time is only half full. What could be filling up that C drive?

    Would it make any sense to copy D drive data to a CD for backup? Could it be used as a boot up disc?

    When I bought my Dell Inspiron notebook computer a year ago it did not come with the recovery disks, or disks for the software installed on the computer. Later I read somewhere that if you send a request to Dell they will send you the disks for the computer, FREE! I went to the Dell web site and, after digging a little, found the link to request the disks. Dell quickly sent me the system recovery disks and the disks for all the software installed on the computer, at no cost, not even shipping!
    I routinely do image backups using Windows Backup so I doubt I will ever need the recovery disks, but I feel safer having them.
