hi,

Finally my Ext HD is working normally. But I don’t use the step above. The Seagate FreeAgent is set up the STAND BY Mode by 1. I have to change it to 0 value with command :
#sdparm –clear STANDBY -6 /dev/sd?

And for checking it has been changed, use command :

#sdparm -a /dev/sd?

Ok thanks cherpec…..

OK I have put /scripts/usbhdfix permission to executable.

I’ll report to you again for the result. Thanks

ok This is my /scripts/usbhdfix file

#!/bin/bash

# USB FIX:
# http://ubuntuforums.org/showthread.php?t=494673

echo 1024 > /sys/block/sdd/device/max_sectors
echo 1 > /sys/block/sdd/device/scsi_disk:*/allow_restart

I have replace the sdd as your sugestion. What about the permission ? I have :
1. /scripts/usbhdfix = 644
2. /etc/udev/rules.d/85-usb-hd-fix.rules = 644

should I change the permition ? Many thanks

Check that you have execution bit on /scripts/usbhdfix.
You can try to execute script from command line:

# replace sdX with drive’s device name
/scripts/usbhdfix sdX

# verify
cat /sys/block/sdX/device/max_sectors
cat /sys/block/sdX/device/scsi_disk:*/allow_restart

Helo Cherpec,

Day 1st, it still failed to spin. The Ext HD was stop working again. Hmmm…. I wrote the script like this :

For file /etc/udev/rules.d/85-usb-hd-fix.rules :

BUS==”scsi”, KERNEL==”sdd”, SYSFS{vendor}==”Seagate”, SYSFS{model}==”FreeAgent Go”, RUN+=”/scripts/usbhdfix %k”

Is that correct ? should I change the permission for that file and the other file ? please advice and thanks

You should go with ’sd?’ as it will match all ’sd’ prefixed devices (’sda’, ’sdb’ …).

Hi Silver,

I have same problem with you on my 2 of seagate external drives. What I am asking is on the line :
kernel==”sd?”, should I replace the line of “sd?” with the real drive partition ? or just let it be ?

On my case, my Ext HD read as sdb1. Should I replace it to kernel==”sdb” or something ?

Thank you for your advice.
