Post-Test Configuration:
 ========================
 <none>

• DiskPurge-long.seq – this test does three write passes of the entire drive, using three different data patterns. After each write pass an entire read pass with data compare is done to verify the data overwrite. Note: These read passes are not required to meet the DOD 5220-22m spec
• DiskPurge-short.seq – this test does three write/verify passes of the entire drive using three different data patterns. It will run in half the time of the long test
• DiskErase-Speedy.seq – this test does on complete overwrite of every block on the drive, using a random data pattern.

1. Writes entire drive with alternating 0/1 data pattern
2. Reads entire drive doing data compare
3. Writes entire drive with alternating 1/0 data pattern
4. Reads entire drive doing data compare
5. Writes entire drive with random data pattern
6. Reads entire drive doing data compare

The test will fail if any WRITE or READ command fails, or if any data compare fails. This is the same process done on DOD certified tests.

1. Writes and read with data compare. 1000000 blocks at beginning, 100000, and 2000000 blocks into drive.
2. 2 minute random access write/read with data compare
3. Records P and G defects to log file at beginning and end of test

1. 2 minutes of random access write/read with data compare, with FUA set on to force access to the drives physical media (rather than cache access).
2. 2 spin down/spin up cycles
3. 2 minutes of butterfly access write/read with data compare and FUA set on
4. 2 spin down/spin up cycles
5. 2 minutes of random access write/read with data compare and FUA set onAll data patterns use random with LBA overlay

1. 2 minute random access read, 128 blocks/transfer, FUA set off
2. 1 spin down/spin up
3. 2 minute butterfly access read, 128 blocks/transfer, FUA set off
4. 1 spin down/spin up
5. 4 minutes random access read, as above
6. 1 spin down/spin up
7. 4 minute butterfly access read as above

1. The same functionality as the original STB “Disk Confidence Test 1”
2. 1GB sequential write, incrementing data pattern
3. 1GB sequential read with data compare
4. 5000 random access seeks (1 block read)
5. 4 spin down/spin up cycles

1. Make sure blocksize is 512 bytes/block
2. Make sure there are no more than 1 grown defect
3. Spin up all drives
4. Clear drive LOG pages
5. Sequential write 1000000 blocks, LBA data pattern
6. Sequential read 1000000 blocks with data compare
7. 5 minute butterfly write/read with data compare
8. Log number of primary and grown defects to log file

1. 11 minutes of write, 4 minutes of read
2. Incrementing data pattern with LBA overlay
3. Data compare on reads

1. Test to simulate a data server application
2. 15 minute random write/read, random transfer lengths, data compare

Tape Manufacturing Module (TMM)

Sequence Files – Open these files in the Tape Manufacturing Module

1. Writes and reads 2GB of 2:1 compressible data with compress set on and off. Clears LOG pages before each test, records LOG pages after each test.
2. Writes 3 files marks at beginning of tape, and skips over them during testing – to help test using a tape that is worn at the beginning of tape.
