Hi I am having a SATA 250 Gb Segate Barracuda harddisk,
Wanted to connect it to my laptop, so i bought a SATA to usb converter.When i connected it to usb port, opensuse 11.0(with latest kernel image) detected it, but it hardly showed the drives for 2 or 3 minutes! The drives unmounted automatically !!!
And the same is happening over and over.
Hard drive is having approximately 200 Gb of data.
What exactly is causing the problem?
Any suggestion!!!
Hi papadam
The first thing that springs to mind is the external HDD power requirements vs the available power of some usb ports (especially laptops). I’ve seen external drives that start then stop before the OS even gets to mount them properly. (Please disregard this if I’m on the wrong track here).
I have a seperate adaptor for supplying the power to the hard drive.
Not powering the hard drive from the +5 & -5 of USB port.
Sorry to break bad news, but seems like a known problem with some Seagate hardware. Check this link out:

As a workaround, you could keep the drive active with a small cron job.

Issuing the command: (as root)
sdparm --clear STANDBY -6 /dev/sd[Your device]
Often helps, I bought one of these drives since it was cheaper than the
others. Of course, now I know why.
The command clears the preset ‘idle shutdown’ table in the controller.
I pulled the drive out, put it in another enclosure, I use the enclosure it
came with to do troubleshooting on laptop drives and such… but it’s not in
use on the main system anymore. {Grin}

I think I remember reading that you have to hook the drive to a Windows box, install the software and then turn the power management off (set it so the drive won’t go to sleep). After this it should stay hooked up. I haven’t tried it so I can’t verify the fix works.
I hate WINDOWS!!! :
I think that not using that hard drive would be a good option rather than switching to WINDOWS!

I agree. I would also communicate my unhappiness to the manufacturer.
On the tehcnical side, I would be interested in looking at any ‘udevadm montior’ (or dmesg) usb output generated when the device goes to sleep.
I didn’t recommend switching to Windows.
Do you know anyone running Windows? All you have to do is do this one time and then you can hook it back up to your Linux box.
I do think it sucks, however, that there is no Linux support for this function.
HI
I have attached it to my desktop computer,And transferred the data using LAN.
I m going to sell this 5|-|!7 to a potential buyer.
