trouble with backups to external hard drive

[Guest]

Don't know if this is a Vista problem or a hardware problem: using the Backup
and Restore Center, I backed up my files (docs, etc.) and did a complete
computer backup to my new 250GB external hard drive on Oct 31. I then
scheduled a file backup only for every Saturday thereafter. I then turned off
the drive but left the usb attached.

On Saturday Nov 3, I turned the drive on just before the time for the
backup, and shortly the scheduled backup tried to begin, but the drive K:\
could not be found and thus the backup failed. I then turned the drive off,
rebooted the pc, then manually started the file backup from the Backup
Center. It worked this time. So, feeling pumped, I thought I'd try the
complete backup again, but once again the pc could not find the drive.

The drive came with a backup utility (Memeo AutoBackup) that I chose not to
install because Vista has a good backup utility. Does anyone out there have
any suggestions or observations on what is happening here? Mike

this problem has been solved. no need to reply. the external drive has a
switch on back which allows me to select Auto backup or Manual backup. i
switched it to Manual and was able to complete a full pc backup, and verified
it.
