Why does MS-DOS BACKUP introduce CHKDSK errors?
#47

	I just performed a full hard disk (10 MB) backup using MS-DOS
BACKUP command  (BACKUP C:\ A:/S) on my Compaq Plus.  Before doing the
backup, CHKDSK told me that my directory structure was in order.  After
doing the backup, CHKDSK told me that I had an allocation error in one small
file in a subdirectory; adjusted the size; then told me that I had one lost
cluster in 1 chain and that that file was now cross linked to another in a
different subdirectory on cluster 512 (in both files).
	Well, I tidied all that up, but what I want to know is:  How and why
did it happen?  I would have thought that making a backup involved only
*reading* directories, not fiddling with them, so how did things get
changed?  Also, are my backup disks likely to be in order?  How can I tell?
(I'm not about to reformat C: and restore just to find out!)
	Thanks in advance for any help.
