Backup device creation problem

I have an issue while taking a backup into a device. It
throws out as below
" Cannot open backup device 'D:\MSSQL7\BACKUP\xyz.bak'.
Device error or device off-line. "
Can anyone who has already experience this help me out ?
Thanks,
Raghu1. Is D: a local drive?
2. Is xyz.bak writable?
3. Does the account under which the SQL Server service runs have permissions
to access the file?
