SubjectRe: FW: PDC202XX DMA loss in 2.4.21-pre3-ac4
his is the help from smartctl:

smartctl version 2.1 - S.M.A.R.T. Control Program
useage: smartctl -[opts] [device]
Read Only Commands:
a Show All S.M.A.R.T.
Information (ATA and SCSI)
g Show General
S.M.A.R.T. Attributes (ATA Only)
v Show Vendor S.M.A.R.T.
Attributes (ATA Only)
l Show S.M.A.R.T. Drive
Error Log (ATA Only
L Show S.M.A.R.T. Drive
SelfTest Log (ATA Only)
i Show S.M.A.R.T. Drive
Info (ATA and SCSI)
c Check S.M.A.R.T.
Status (ATA and SCSI)

Enable / Disable Commands:
e Enable S.M.A.R.T. data
collection (ATA and SCSI)
d Disable S.M.A.R.T.data
collection (ATA and SCSI)
t Enable S.M.A.R.T.
Automatic Offline Test (ATA Only)
T Disable S.M.A.R.T.
Automatic Offline Test (ATA Only)

Test Commands:
O Execute Off-line data
collectioni(ATA Only)
S Execute Short Self
Test (ATA Only)
s Execute Short Self
Test (Captive Mode) (ATA Only)
X Execute Extended Self
Test (ATA Only)
x Execute Extended Self
Test (Captive Mode)(ATA Only)
A Execute Self Test
Abort (ATA Only)

Off-line data collection has nothing to do with the
SMART data collection. You enable the offline test,
then run the test and collect the offline data.

I agree with the fact that we have the lower 24 bits.
However, SMART attributes displayed is appropriately
collected from the drive. Look at the sequence below:

bash# ./smartctl -a /dev/hda
Device: ST380021A Supports ATA Version 5
Drive supports S.M.A.R.T. and is disabled
Use option -e to enable
bash# ./smartctl -e /dev/hda
bash# ./smartctl -a /dev/hda
Device: ST380021A Supports ATA Version 5
Drive supports S.M.A.R.T. and is enabled
Check S.M.A.R.T. Passed.

General Smart Values:
Off-line data collection status: (0x82) Offline data
collection activity
completed
without error

Self-test execution status: ( 0) The previous
self-test routine completed
without error
or no self-test has ever
been run

Total time to complete off-line
data collection: ( 422) Seconds

Offline data collection
Capabilities: (0x1b)SMART EXECUTE
OFF-LINE IMMEDIATE
Automatic
timer ON/OFF support
Suspend
Offline Collection upon new
command
Offline
surface scan supported
Self-test
supported

Smart Capablilities: (0x0003) Saves SMART
data before entering
power-saving
mode

auto save timer

Error logging capability: (0x01) Error logging
supported

Short self-test routine
recommended polling time: ( 1) Minutes

Extended self-test routine
recommended polling time: ( 57) Minutes
