4. Click Save.
Compression files are downloaded. To decompress the compression file, you will obtain binary
files containing the results of the shredding operation and text files containing contents and
results of the shredding operation.
The name of the binary file indicates LDKC, CU, and LDEV numbers of the shredded volumes,
and the number of times dummy data have been written to the volumes. For example, if a
binary file is named 00-01 11 03.bin, the LDKC number is 00, the CU number is 01, and
the LDEV number is 11. The filename also indicates that dummy data have been written to
that volume three times. A binary file contains the first 512 bytes of data of a shredded volume
(LDEV).
The file name of a text file is displayed as follows;
shred_the-finish-time-of-shredding-operation.txt
The compressed file is saved with the time zone setting of SVP. If the compressed file is
decompressed on the Remote Web Console computer, the time stamp of the decompressed
file is displayed with the time zone setting of the Remote Web Console computer. Therefore,
the time stamp of the decompressed file might be different from the actual finish time of a
shredding operation.
The text file contains the following summary information of a shredding operation:
• Results of a shredding operation
• Contents of the dummy data
• Shredded volumes
• Start and finish time of a shredding operation
