Disk Test/Clean

This test causes the file system to scan the disk for bad sectors and
remove these blocks from the addressable space. This test destroys
all data on the disk and should not be attempted on a good disk.
Normally this test will only be used when the disk contains bad data
and is therefore unusable.
The test is actually executed in two distinct phases: a writing or
cleaning phase and a verifying or testing phase. During the cleaning
phase, the printer writes a 0x00 to each byte location on the disk.
During the testing phase, the data written is verified.
This can be an extremely lengthy test; however, the test length
depends on the disk size. For example, each phase of this test
executed on a 540MB hard disk takes approximately 14 minutes to
complete.
This test leaves the disk unformatted. The servicer or user must
reformat the disk using the Format Disk menu operation.
To run this test, select Disk Test/Clean from the DEVICE TESTS
menu. The following message is displayed to warn the customer that
all disk contents will be lost. To continue on with the test, press Go.
To exit the test immediately and return to the DEVICE TESTS
screen, press Return or Stop.
Once Go is selected, the following screen is displayed to indicate the
cleaning phase of the test has begun. This screen is periodically
updated to indicate the percentage of the cleaning phase which is
complete and number of bad blocks which have been found. The
Power indicator also blinks while the cleaning phase is in progress.
When the cleaning phase of the test is complete, the following
screen is displayed to indicate the testing phase of the test has
begun. Again, the screen is periodically updated to indicate the
Files will be
Lost. Go/Stop ?
