HDD GURU FORUMS :: View topic - Unable to clear SMP flags

You could try issuing the following Case Sensitive commands at Level T.

Code:

F"READ_SPARING_ENABLED",0,22
F"WRITE_SPARING_ENABLED",0,22
F"OFFLINE_SPARING_ENABLED",0,22
F"DAR_ENABLED",0,22
F"DISABLE_IDLE_ACTIVITY",1,22
F"BGMS_DISABLE_DATA_REFRESH",1,22
F"ABORT_PREFETCH",1,22
F"READ_LOOKAHEAD_DISABLED_ON_POWER_UP",1,22
F"READ_CACHING_DISABLED_ON_POWER_UP",1,22

, drive has same symptoms.

SMPs didn't get changed after issuing those commands. Didn't you apply wr protect patch by any chance?

When editing SMP flags on rosewoods you need to do it via ATA, not terminal in the drop down menu. It will trhow not supported by firmware. You use the normal "edit HDD ID" in the drop down. Alternatively you could read the module, edit it and write it back under work with rom.

Or you can issue terminal commands as stated above. Though if this is a rosewood SSHD you must disable flags via terminal commands otherewise you brick the drive.

Weak head can also cause this but there is probably more if this is a partial. May be really bad platter conditions or platter damage on that head.

Also when I check sysfile 93 all unchecked flags are not actually cleared. SMP Dbl: 0x3C001000 - 0x0001FFFF (0x0000000F) and MCMT not available error is also displayed i

Frustrated with drives behavior I outsourced this case & got a reply that Head 1 is weak & drive is having large TEC sectors , recovery will be partial & will need head transplant

I feel its better to use terminal commands each time.
