Backing up laptop to 500gig Hard Drive.

Last night, another weird thing happened.
Every time I import a new or customized disc in the laptop e1505, using the ext. Plextor, I use a backup program to compare the C drive Hoster song folder to the backup hoster song folder in the HD, then it adds the newly added files to the HD and keeps it exactly the same as the laptop's C drive's Hoster songs. I do this with two backup HD's, exactly the same model and size.
When doing this last night, I imported 18 new songs from a customized disc and also edited two other songs that were already in there. When the backup compared the C drive with the F backup ext HD, it found that 20 new songs need be added, which is correct, 18 + 2.
However, when I did the exact same process with the other ext. backup "E" HD, it saw there was only 18 songs to update. Why? I do not know? So essentially i had to find those two songs from the F drive and copy over to the E drive in order to get the edited songs in both drives.
Could there be any explanation for this? I think this may have been happening for some time and I'll need to go back and compare F and E ext HD's song for song to get two identical HD's copied correctly.

I've read some posts on permissions. Would this have anything to do with this deal?

To summarize the above, in essence, one ext. HD does NOT recognize files that have been modified with a new date, it only recognizes NEW files.

The other har drive recognizes "edited" filenames and such, AND new files added.

Any ideas on what stupid thing I am doing here?

The fact that you can move them manually suggests to me that you have permission and I believe with XP you have permission by default, Though it wouldn't hurt to open the properties of those drives and compare them for differences that mght seem applicable.

Another thought would be that perhaps in your backup program you have to set the parameters for what is to be backed up. Perhaps one drive is set to copy over anything newly created or modified, whereas the copy parameters for the other drive might be set to ignore modified files and just copy over new ones...Just a thought.

I'm not familiar with backup programs so I can't think of anything else to suggest.

Thanx, I've checked the program parameters (I thought) and they were pretty basic and comparable). I'll double check the drive properties and compare precisely.
