Re: External USB hard drive "loosing" connection [Maxtor onetouch]

I also suspect that its due to sleep mode. Could it have something to with
the fact that I reformatted the drive to ext3 from NTFS?

Was the hard drive not mounted? What did the program mkfs.ext3 end
with after it quit?


I found this article claiming that there is no problem with Maxtor drives.[
http://www.engadget.com/profile/1588927/].


Maxtor has a long history of failure. I will never buy one. I buy
only Western Digital because I have a giant 40 MB one I bought in 1985
and it is still good. All the newer ones are good.
Here are the errors I see in syslog.

.


localhost kernel: [174463.681864] sd 1:0:0:0: Device not ready.
localhost kernel: [174463.681885] end_request: I/O error, dev sda, sector
4655

This looks bad. Ubuntu doesn't use sda, it uses hda.

localhost kernel: [174463.687888] Aborting journal on device sda1.
localhost kernel: [175036.945142] ext3_abort called.

Hi,
I recently bought a Maxtor onetouch extenal USB drive 500GB for backup

for

my ubuntu dapper system.
Every morning the backup script fails because it has problem in

accessing

the drive. Once I manually remount(sudo umount /dev/sda1; sudo mount
/dev/sda1) the drive and restart backup it works fine.
Has anyone seen this problem before? Any workarounds for this?

I'd simply start the script with "sudo umount /dev/sda1; sudo mount
/dev/sda1" That is, if it is a bash script. Other types of scripts
would need other commands, or a new script with that and the command
to execute the original script.
If you run the script as root (in the root crontab) it shouldn't even
be necessary to use sudo.
It might even be useful for the harddrive to shut down with the power
consumption.

just my 2 cents

Neil
