Ubuntu :: Reads Only One File On D Drive After 10.10 64 Bit Install

Dec 26, 2010

Due to crash of 10.04 grub, I installed it again from a live CD on D drive "C drive has windows 7", then immediately after install, I upgraded to 10.10 64 bit. Need to change the boot to Windows loader and not directly to Ubuntu as it happens now. I see "windows loader as an alternative option" and it works when I select it. when I boot to windows, my computer icon reads only one file on D drive "bootsqm.dat". from Ubuntu computer option, I can access all windows files.

General :: Difference Between Buffered Disk Reads And Cached Reads?

Jul 13, 2011

I was analyzing the Disk read using hdparm utility. This is what i got as a result.


# hdparm -t /dev/sda


Timing buffered disk reads: 108 MB in 3.04 seconds = 35.51 MB/sec


# hdparm -T /dev/sda


Timing cached reads: 3496 MB in 1.99 seconds = 1756.56 MB/sec I m not sure what does Cache read and buffered disk read mean.

#~ Open socket.

General :: Program That Reads Multiple Pipes / File Descriptors And Writes To Standard Output

Feb 23, 2011

Is there already a program that reads multiple pipes or file descriptors and writes to the standard output (not splitting lines).Like cat, but reading all files simultaneously and preserving lines.It is needed to avoid coding of select/epoll loops or using multithreading in simple programs. Like "select loop for bash".

OpenSUSE Install :: Every Boot Message Reads "previous Installation Failed"?

Nov 22, 2009

I finally did it. I took the plunge and moved away from MS and installed openSuSe on my system. I have a Gateway 650 with 160 MB of ram and yes it did install! To top it all off it also boots to Windows XP. This was all working fine until I < me < myself < yes I am a gonna admit >>USER ERROR<< booted the system into windows and I decided to see if my system needed to be DEFRAGGED. Yup I did.. I ran the defrag on the system and when it was all said and done my NTFS file system was all nice and pretty no more fragmented files.

So I decided to reboot the system to see that wonnerful boot loader of openSuSe and I chose the 11.2 to boot to and I get the message that the previous installation failed and it starts to run the script to "fix" the installation. It hangs on around 4% the installation. I hit ctrl alt del and it boots into the openSuSe partition and it seems to be working, but I have that durn annoying screen of the "previous installation failed". Are there any ideas on how to as my GF 4 yr old daughter says "flix it"? Or do I have to go through the PAINFULLY SLOW installation again?

OpenSUSE Install :: Grub Error 18 - Unknown File System - Running From External Hard Drive

Jan 11, 2011

It started when I wanted to dual boot Windows 7 and Opensuse off of my netbook (No DVD/CD drive) I tried install suse from an external hard drive and I botched it. I ended up erasing EVERYTHING off of my internal netbook hard drive. Windows and all.

Well, I had a couple of other computers so I studied up and eventually successfully installed OpenSUSE 11.2 on my external hard drive (11.3 being the one that I accidentally erased everything with, so kinda scared of it) and now I want to install openSUSE 11.2 on my internal netbook hard drive.

I can not use disks

I can not use a flash drive (For some reason, even if I make it bootable, it will not load up, this could be because it's actually a 8GB microSD card that is placed in a USB card reader.)

I can not use an external hard drive because that's what I'm running suse off of.

I've tried reading up on how to install suse on another drive off of the hard drive and I've gotten as far as whenever I boot up the netbook with the suse external hard drive connected it will ask to boot into OpenSUSE, the Fail Safe, or to install OpenSuse. When I select to install it it gives me the Error 18 Unknown File system.

I've tried formatting the internal hard drive twice. One as NTFS and again as EXT4. Neither seems to effect it other than when it's ext4 I can open it and it contains a Lost and Found folder.

When I interrupt the boot sequence by pressing c and going to the terminal and I use the root (hd +TAB command it tells me I have a hd0 and a hd1. The hd1 only has 1 partition which is ext4, which I'm assuming hd1 is the internal hard drive (I'm not sure how to check) and the hd0 is the external hard drive, which has three partitions. One with an unknown file system and two with ext4. When I try to enter the set up from the terminal it gives me the same error for any thing I put it (e.g. root (hd0,0) gives the same error as root (hd0,1), or root (hd0,2) and root (hd1,0)

Something like it cannot locate these two files I'm assuming it needs to boot. If anyone finds this relevant I'll retry it and post the files its missing.

I've been searching for awhile and can't find any threads that can solve my problem. From other threads, however, I have noticed that I should probably include my menu.lst, listed below


I have also ran the boot info script and received the RESULTS.txt file it generates. Listed below

Ubuntu Multimedia :: 10.04 VUmeter Reads Ok But Still No Audio

I used to have audio working. Now it's silence while the vumeter reads as if all streams are outputting okay. I have a Radeon HD 4670 with audio out the HDMI as well as audio out the motherboard simultaneously. This all works in windows 7 and used to work in ubuntu until some point, not exactly sure when, it all went silent. Also, fyi, I started with a clean 9.10 and upgraded to 10.04.

Ubuntu :: RAID6 Writing Faster Than It Reads

Ok first off the write speeds are off the hook, 210MB/s on 5400RMS disks (5 disks in a RAID 6). However, read speeds are 68MB/s. I wondering first off, why? and secondly could this be an indicator of something not properly setup that might cause harm to my disks?

Ubuntu Installation :: Sony Vaio Reads Only Original Cds?

Aug 14, 2010

i'm trying to install ubuntu on a sony vaio. Unfortunately i cannot boot from a cd on which i have burnt the .iso file of ubuntu. The only way i managed to install ubuntu was by creating a usb bootable stick, but here also that doesn't work so well. My workaround was to use virtual clone drive which is freeware to simulate a cd rom in windows and get the iso file started. By leaving the bootable usb stick in the computer in this way it worked...

So in the end i have grub and can load ubuntu and win xp, but then by trying to format the harddrive i kind of messed things up and had to reinstall windows. Because the DVD drive only reads original cds. So from there i will attemp to reinstall ubuntu again. But how can i get rid of win xp afterwards ? If that CD Rom would only read burnt cds or if it would habe been possible to boot from usb then i wouldn't have this trouble.

Ubuntu Multimedia :: Which Gnome Part Reads Mp3 Librarys?

Feb 3, 2011

Maybe a simple question, im not sure what is running behind the curtain.


are doing the same thing with my 14k mp3 library. They all dupe exactly the same files with every full rescan of the existing music library. So i guess they all use a gnome system part for this job and there is a bug inside this part. I want to file a bug against this part but don't know the name.

Ubuntu :: Samba Slow Writes To Server But Fast Reads

Jul 1, 2010

I have a fileserver running 10.04 server 64bit and samba. I connect it to my desktop which is 10.04 desktop 64bit.I have the server mounted on my desktop in fstab as:// /media/share cifs guest, uid= 1000.Up until 30 June 2010 it was all fine. Now when I write the server it is very slow e.g. 2Mbps though when I read I get >100Mbps so I think my network is still ok. If i use nautilus smb:// I can write at >100Mbps and also read at >100Mbps...So any ideas why the write speed via the fstab mount samba has started to go really slowly in the last couple of days?

Ubuntu Servers :: Raid1 Reads At Single Disk Speed?

May 3, 2011

im on 10.10(desktop) and mdadm was v2.8.1 from 2008, very out of date so i tried 3.2.1 -> no change. mdadm raid1 read speeds are the same as single disk. note i used the tests in the disk utility benchmarking tool at first --these showed raid 5 atleast to be much better but when i tried dd reads raid5 dropped off with larger data to almost the same (slow) speed as raid1. compare:


using two partitions will be enough to show raid1 performs at single disk speed. I dont really want to use a 4 disk raid0 just to get the read speed i should be able to get with raid1 as i dont really care about the size loss. I would of course use raid10 but i have found this suffers from the same problem (achieve same read speed as 2 disk stripe). So whilst im shocked others aren't reporting this, unless there is some obscure reason why my system would give these results i think raid1 in not behaving as it should.

OpenSUSE Multimedia :: Amarok Reads Media But Does Not Play It / Fix It?

Nov 23, 2009

It isn't that I don't get sound. It just won't play. If I click a file, then click play it quickly goes through an amount of songs. Too quick to give a good number. For example, if I have 100 songs on my library, I want to play one. Obviously I click play and such to make it play but instead of playing it acts as if it can not read the file (even though all my songs are in the library). Got any help/tips/whatevers?

Hardware :: HP Printer Still Reads Ink Level Empty Even After Replacements

Jan 25, 2010

My father has an HP PSC 1510 All in One Printer - Scanner - Copier. I have recently managed to convert him over to Linux, his current distro of choice is Fedora 12.Everything was going surprisingly well until recently: the message came up on his screen saying that the ink levels were low. After replacing the cartridges the message continued to appear. However the main nuisance is that it will not allow the printer to print at all now.

The cartridges are working as he still has vista on his system and logged in and printed out from there without hassle. Is there a way to reset the memory of the printer in Fedora? I am not much help to him here as I know nothing about printers.

I got a CD with a book - doc files.When I look at it with nautilus or with wine notepad it tells me that the CD is empty. capacity 49.4 MB. It does show the name of the CD BOOK2XTRAS - so at least the name field in the first sector is where it is supposed to be.When I boot to my 2nd drive - an old win98 sys - it sees all the files on the CD. Same CD drive in each case. I go to another fedora computer I have and it does n.ot see the contents either.

Programming :: Bash Script That Reads Lines In While Loop

May 26, 2011

So I need to write a bash script that can read lines and column 3 from a file. It needs to start on line 16 and read every 20th line starting from there. But the value that it reads needs to be checked, should it be too great I need it to shut the program down.I'm pretty new to bash, but my ultimate goal is being able to safely run a program on a GPU for an extended period of time with out worrying about it overheating. I have a command that outputs information from the GPU every second, and I can save this to a file. So all I really need is something to read and check that file, I played around a bit with the awk command and can't get it to work within my for loop with dynamic variable.
