Managing storage media

CAUTION:

To avoid file system corruption:

• On an MSR2000 or MSR3000, do not install or remove a storage medium while the system is repairin

or formatting a storage medium.

• On an MSR4000, do not install or remove a storage medium or card or perform active/standby

switchover while the system is repairing or formatting a storage medium.

If you remove a storage medium while a folder or file on the storage medium is being accessed, the

device might not recognize the storage medium when you reinstall it. To reinstall this kind of a storage

medium, complete one of the following tasks:

• If you were accessing a folder on the storage medium, change the current directory.

• If you were accessing a file on the storage medium, close the file.

Before you repair or format a USB disk, make sure the disk is not write protected.
