Restoring Deleted Files

You must specify the index number of a deleted file to identify the file to undelete. The index number
for each file appears in the first column of the dir command output. A file cannot be undeleted if a valid
file with the same name already exists. Instead, you must delete the existing file and then undelete the
desired file. A file can be deleted and undeleted up to 15 times.
To restore deleted files on a Flash device, perform this task in privileged mode:
Task
Step 1 Identify the index number of the deleted files on
the Flash device.
Step 2
Undelete a file on a Flash device.
Step 3
Verify that the file is restored.

Console> (enable) dir deleted
-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name
6 .D ffffffff 42da7f71
1213952 bytes available (3231989 bytes used)
Console> (enable) undelete 6
Console> (enable) dir

Verifying a File Checksum

To verify the checksum of a file on a Flash device, perform this task in privileged mode:
Task
Verify the checksum of a file on a Flash device. verify [[m/]device:] filename
This example shows how to verify the checksum of a file:
Console> (enable) verify cat4000.4-4-1.bin
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
CCCCCCCCCCCCCCC
File bootflash:cat4000.4-4-1.bin verified OK
