[SOLVED] Dolphin can't see external drive

[SAlineBoy]

Greetings all
Booted my PC up earlier, went into Dolphin to move some files from the back up external drive to the HDD. Problem is my external backup is not showing up? Where would I start to look for a reason for this?
Regards

[djennings]

plug in the drive, then in a terminal

Code: Select all

su
mount
dmesg
tail -n 50 /var/log/syslog

mount will show currently mounted drives
dmesg will show if the drive was detected and its device number
syslog will show if it got mounted or if an error was detected

Hi
Tried the commands you have suggested. Would have posted them, but too many characters. Having gone through everything I cannot see the ext HDD anywhere.

What else would you suggest?

Leave out the full output of the "dmesg" command, but post the rest.

You haven't said what type of external HDD it is - USB? - Network? - or what?

After plugging in my external USB HDD, the last line of output from mount is this:

Code: Select all

/dev/sdc1 on /media/BackUps_ type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096)

Do you see anything resembling that.

Hi
Drive is a USB Fujitsu Siemens Storagebird

Result of "Mount" is:

Code: Select all

/dev/sda1 on / type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)
[...]
/dev/sdb6 on /var type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)
/dev/sdb5 on /tmp type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered)
/dev/sda6 on /home type ext2 (rw,relatime,errors=continue,user_xattr,acl)
usbfs on /proc/bus/usb type usbfs (rw,relatime,devgid=43,devmode=664)

Unfortunately the latter doesn't have the required output, or you did it too long after pluggin the drive.

Please do the following:

• 1. unplug the drive
• 2. open a terminal, as root do tailf /var/log/messages
• 3. plug the drive, wait half a minute
• 4. post the newly added output from the terminal here

And please use code tags next time: ftp://ftp.mandrivauser.de/rpm/rpm/extra ... e_tags.ogv

What are code tags?

[isadora]

SAlineBoy, click the link doktor5000 provided.
It is presenting you a screencast explaining all about the use of code-tags.

[SAlineBoy]

.....clicking on the link just refreshes the page.......

[doktor5000]

Under which browser?

Apart from that, if you did exactly as i described, seems your computer is not detecting the external harddrive at all.
Are you sure it is correctly powered on and not in any powersaving mode? Did you try a different USB port? Can you try to connect another USB device, like a mouse or usb stick in the ports you tried? Does the harddrive work correctly when attached to another computer or operating system?

[SAlineBoy]

Hi
Chomium browser

Drive is powered up, not in powersaving mode, I can hear it humming, tried in all ports, all other devices work in all ports, unable to check in another pc.

Up until last night it was working. It sounds like it is trying to seek.

[doktor5000]

When was the last time you powered it on?

[SAlineBoy]

This morning, just before I powered the pc up

[doktor5000]

Well as you didn't access it in the meantime, why not unplug it from the computer and try to power it off and back up again, and then plug it in?

[SAlineBoy]

powered down pc, unplugged power and usb from external HDD. powered up pc, reconnected hdd and powered it up. Still not detected.

Must leave now. I will resume tomorrow am.
God bless

[SAlineBoy]

Powered up pc and external drive this morning. Both now working.

While I am delighted that all now works, I would still be interested to know what happened. As this is our back up drive, it is important to us to know it's reliable.

I may just bite the bullet and buy a new one, but if I could save myself some money all the better.

Anyone any ideas or opinions?

[doktor5000]

Yep, run gsmartcontrol over it and post the results here.

For reliable hard drives, i'd personally only recommend Western Digital, and only the Caviar Black ones as those get you 5 years warranty.
And if you use it as backup drive, bite the bullet and get a NAS which allows for a RAID 1 at least, so you have at least somee redudancy.
Although that shouldn't be your only backup solution for critical data ...

Many thanks
