Ubuntu :: Prevent External Drive From Sleeping?

Aug 26, 2010

I have a Hitachi SimpleDrive (LS-1000-EMEA) it has an "Auto-sleep" function which I believe is controlled by the enclosure itself.The problem I'm having is that when the drive goes to sleep Ubuntu does not seem to be able to wake it up again. I am running Karmic 9.10 as a stripped down install with XBMC as a front-end. I cannot access the drive at all when it does this.

I'm not sure if the problem is that the drive is formatted as NTFS. I notice that when the drive is connected to my Mac or PC it resumes no problem (with a slight delay as the drive gets out of standby) but with Ubuntu it just seems to stop responding. When I reboot the drive is not mounted by Ubuntu. Physically, the blue LED indicator on the drive is frozen (i.e. lit-up) rather than flashing as it normally would. I have to actually unplug (from the mains) and plug it back in for it to work.I have tried using sdparm, but as I say I think the sleep function is controlled by the enclosure and thus sdparm gives me no standby options.

Ubuntu :: External Harddrive Not Booting / Prevent This From Happening?

Mar 21, 2010

I installed Ubuntu on a portable harddrive so that I can use it independently of my computer (when I visit my parents or my g/f). I performed the installation using a bootable Ubuntu thumbdrive, everything went fine but when I unplugged the thumbdrive and rebooted I got a kernel panic. I was able to boot into Ubuntu on my external drive once (I think it might have been due to reordering boot order in BIOS). My guess is that the kernel panic occurs due to the drive letter changing (sdb -> sdc) depending on which external devices are plugged in, but I'm not sure how to make sure that's the case. And if it is, how would I prevent this from happening?

Ubuntu Installation :: Installing 11.04 On External Hard Drive Drive?

Jun 19, 2011

I would like to install Linux Ubuntu 11.04 on an external hard drive - its partitioned and ready for Linux.I've downloaded and burnt the .iso file to a DVD so its all good so far...First of all... is this possible without messing up my macbook? I don't particularly want to break into my macbook to disconnect the hard drive (I read on a tutorial for a previous version of Ubuntu that I'd have to do that... - does it still apply to 11.04?) - as it voids the warranty (I checked ).The reason I ask this is because I had a friend who partitioned their internal hard drive and installed Ubuntu on it. But after installation was complete they couldn't boot up Windows 7 or Ubuntu... and it resulted in them having to clean install Windows 7... - I don't want to end up in that situation

Second... If it is possible to install it without messing up my macbook... - Do I just follow the install instructions but just make sure that where possible I make sure that everything is installed on my external hard drive?...I really need someone to put my mind at rest that everything will run smoothly and that I'll be able to run Mac OS X as usual but also that I'll be able to boot from my external hard drive to run Ubuntu.

Fedora :: Prevent Mounting Of External Drives & CD / DVD Drives

I suspect this is not new but I just can't find where it was treated. Maybe someone can give me a good lead.I just want to prevent certain users from accessing CD/DVD drives and all external drives. They should be able to mount their home directories and move around within the OS but they shouldn't be able to move data away from the PC. Any Clues?

Ubuntu :: Seeing Folders - Plug In The External Drive And Get Error "format The Drive"

May 30, 2010

I'm not sure what to do, but I just rescued photos and documents using ubuntu live cd, gddrescue and photorec. The data carving went fine and I was able to move all of my recovered jpg's into a recovery/jpg folder, as well as my word doc's into a recover/doc folder. I also have recovery/video and recovery/audio. Now here's my problem...

I used the right-click "safely remove drive" from the ubuntu interface and then unplugged my external drive. I then tried to view the recovered photos, etc on my windows 7 desktop, but when I plug in the external drive I get an error and a prompt to "format the drive" so that windows can use it.

I plugged the external drive back into my failed laptop and with the ubuntu live cd can see the drive, but none of the folders display. I can cd "change directories" to all of the folders using a terminal, but still can't see them outside of the terminal. That is, with the ubuntu interface. I'm just trying to finish up recoverying these photos, which I thought I had done.

Red Hat / Fedora :: Reformatting External Drive - Error "drive Doesn't Show Up At All Via Df -k"

Apr 15, 2011

I need to re-format an external drive. All the instructions I have found start with figuring out where the drive is mounted (sda, hda, etc.). However, as soon as my RH Linux machine sees the drive's format (ntfs) it decides it won't even mount it in the first place. Gives me an error message. Also, the drive doesn't show up at all via "df -k". how to convince RHL to be a little more accepting?

Ubuntu :: Eee904hd Sleeping Randomly / Solution For This?

Apr 30, 2010

Yesterday, I clean installed the netbook remix of 10.04 , all went well, until I removed the power cable.

While off mains the netbook will randomly sleep, I really can't seem to find a trigger for it.

In the power settings I have changed various options to alter this but nothing seems to affect this.

This machine had xp on previously without a similar problem, so I am ruling out a faulty lid trigger. (Doesn't happen with powered on mains)

Ubuntu :: How To Name A External Drive

Aug 22, 2010

I have a USB flashdrive and when ever I plug it in it's named CORSAIR. This I like. Now I have some external hard disks that I use for back up. They are USB also, but they tend to get some random name that is mounted to /media like disk-1. How can I name a specific drive to something like "backup" and have it always be recognized that way even across different different Ubuntu boxes.

Networking :: Wicd Has Connecting To New AP's After Sleeping?

Jul 6, 2011

I was using wicd on a spotty network, the house blocked a lot of the signal from moving around, so wicd was having major issues with that AP. Later I was trying to connect to another AP but wicd couldn't connect plus it was saying the spotty network's name was the one it was connecting to. Although I didn't try before I left/gave up I'm sure a restart of the wicd daemon would have solved it.

But why is this even the case? is there something I could add to the scripts that would clear this issue up? (I also submitted a bug on wicd's launchpad project but haven't gotten any response... I hope this isn't a 'feature')

After rebooting the computer the USB external HDD I use for backup appears and is accessible at /media/OneTouch 4

A few minutes later I check and it's unmounted itself (apparently) because it's no longer there.

Restart the computer and it appears for a while once again, then disappears.

Ubuntu :: External Drive Won't Spin Up?

Jul 2, 2010

I come here as a technical PC user and fan of the Ubuntu forums ^^..I am the current owner of a Western Digital Portable HDD - Blue - 320 GB (Advertised).Recently, I have discovered I had bad sectors (Which were remapped I guess according to Ubuntu's Disk Utility-message that popped up in the upper right)... How is something I don't know because I have already had it replaced due to an internal busted USB port, and have taken really good care of it.Well, I right-clicked in My Computer on the drive (Windows XP) and ran Windows Error Checking on it. It took over a day and finally came up with a failure message. During the test, the drive made funky (yes, funky) noises and now is inaccessible. (It will NOT spin up, or show up as a drive in XP ANYWHERE (Including Device Manager) [but it does go into sleep mode o.0])

I do not have my files backed up, and this is so because this IS my backup =. (Or.. 'Temporary File Storage' for the critics out there.)I have access to WinXP, Vista, Ubuntu, Mac OSX, and Win7, and the bottom line is that I don't know what to do.. I bought it at Walmart (about $100) and also a replacement plan.. but the thing is, I'm not sure if it is dead, and whether or not I can somehow recover my files without disassembly..I'm thinking that maybe the Sata / USB internal interface is dead, but wouldn't putting it into another enclosure void the warrantee?Help? (I'm sorry in advance if this has been posted in the past... I would just like to know what I should do)I know this involves Windows, but from reading what I have, I have determined that this forum has more intelligent people than any other.
