Ignore errors in batch files?

I am trying to write a batch file that will start at Drive A, search for files with the extension of FDB and make a list of those filenames and paths, and save to a text file. If there is no disk or flash drive, I prefer it continue, not stop with a fatal error.
Example:
A:
cd\
DIR *.FDB/S/B > C:\FDBDATA\ADATA.DAT
B:
cd\
DIR *.FDB/S/B > C:\FDBDATA\BDATA.DAT
C:
cd\
DIR *.FDB/S/B > C:\FDBDATA\CDATA.DAT

...and so on until Drive Z.

At the end of creating the files, I can combine them to make one data file. This is the file I am looking for.

My efforts fail when there is no floppy, flash, or pen diskette/drive in those letters. When there is no floppy/pen, I would prefer it just try the next letter and keep on going.

After creating those files, I can combine them and use them for a genealogy program. It would be nice if this would run minimized so a new user won't get stressed at seeing all the commands.

Any ideas please?

Thank you very much.

Try something like (for drive A)

Dir A:
If NOT errorlevel 1 Dir A: *.FDB/S/B > C:\FDBDATA\ADATA.DAT

This should only execute the Dir A: *.FDB/S/B > C:\FDBDATA\ADATA.DAT command if the drive exists. May need some tweaking.

Hope this helps
