Scanning Flash Cards

You can find both structural errors in the data in NVS and physical errors in the flash card. You can also remove files with errors, and attempt to repair structural or physical errors.

check-disk

Use to find and repair structural inconsistencies and damage in the DOS file system in NVS on the primary SRP module.
If the router contains primary and redundant modules, only NVS on the primary SRP module is scanned.
On the E120 and E320 routers only, you can use this command to check and repair a second flash card installed as disk1. You can issue this command in Boot mode for either flash card. In Privileged Exec mode, you can use the disk1 keyword to access the unmounted second flash card while the router is in an operational state.
This command is available for disk1 in Privileged Exec mode only on SRP 320 modules. This command is not accepted for disk0 in Privileged Exec mode.

flash-disk scan

Use to find and repair files with physical errors in NVS. These errors are created if the router is not powered down or reset correctly.
If the router contains primary and redundant modules, only NVS on the primary SRP module is scanned.
Use the repair keyword to fix nonfatal errors found on the disk. If the repair fails, the router no longer uses the corrupted areas.
On the E120 and E320 routers only, you can use this command to find and repair files on a second flash card installed as disk1. You can issue this command in Boot mode for either flash card. In Privileged Exec mode, you can use the disk1 keyword to access the unmounted second flash card while the router is in an operational state.
This command is available for disk1 in Privileged Exec mode only on SRP 320 modules. This command is not accepted for disk0 in Privileged Exec mode.

Example
In this example, the user scans NVS and finds one file with an error. The user then issues the flash-disk scan with the repair keyword to remove the file. Finally, the user scans NVS again, and finds no files with errors.
