Camcontrol not changing modepage

[Tuc at T-B-O-H.NET]

Hi,

	I have a disk thats doing :

THE FOLLOWING DISK SECTORS COULD NOT BE READ: 1131461,

	So I 

himinbjorg# camcontrol modepage da0 -m 1
AWRE (Auto Write Reallocation Enbld):  1
ARRE (Auto Read Reallocation Enbld):  0
TB (Transfer Block):  1
RC (Read Continuous):  1
EER (Enable Early Recovery):  1
PER (Post Error):  1
DTE (Disable Transfer on Error):  1
DCR (Disable Correction):  1
Read Retry Count:  191
Correction Span:  250
Head Offset Count:  204
Data Strobe Offset Count:  5
Write Retry Count:  70
Recovery Time Limit:  3880

	I want to turn ARRE on, which is supposedly
able to be re-written :

himinbjorg# camcontrol modepage da0 -m 1 -P 1
AWRE (Auto Write Reallocation Enbld):  1
ARRE (Auto Read Reallocation Enbld):  0
TB (Transfer Block):  1
RC (Read Continuous):  1
EER (Enable Early Recovery):  1
PER (Post Error):  1
DTE (Disable Transfer on Error):  1
DCR (Disable Correction):  1
Read Retry Count:  191
Correction Span:  250
Head Offset Count:  204
Data Strobe Offset Count:  5
Write Retry Count:  70
Recovery Time Limit:  3880

	I do the "-e" and insert in my editor :

ARRE (Auto Read Reallocation Enbld):  1

	And I get back :

camcontrol: modepage entry "ARRE (Auto Read Reallocation Enbld)" is read-only; skipping.


	Am I doing something wrong?
