Dear All,

How to know what is the device corresponding to a certain external disk? I would like to format it and avoiding any undesirable formatting of other disks.

Thanks in advance,

Paul

The traditional linux hacker way to be sure is to unplug the disk, then do a "tail -f /var/log/messages" and when that is running, plug the disk back in.

You'll see messages appear about /dev/sde (or whatever the name is).

lsscsi is a handy alternative to running dmesg or checking /var/log/messages.

You may have to:

yum install lsscsi

first

Thanks, Ian and Tom, for your help.
