View 4 Replies View RelatedGeneral :: Hard Drive - Driver Keep Saying 0 Bytes Free And Only Root Can Write?
Nov 26, 2010I have a very very insane problem with my ssd sata harddisk. I did fill the harddisk, and Thunderbird complained about "no space left on device". But even if I delete some files from the harddisk, df will still say 0 blocks free. But it will decrease the number of used blocks. So it looks like it is freeing the blocks and deleting the files, but it don't put the blocks back to the free pool.
But here is where things get insane: If I log in with my normal user, I get a "No free space" when I try to write to the harddisk. But If i log in as root I can write to the file system, despite the fact that df is saying 0 blocks free. I did try to run fsck -f but it just run its test and then say that anything is fine. But it run for less then 10 seconds, is this expected on a 40GB ssd partition?.

Programming :: Write USB Device Driver?
Oct 11, 2010I know, I know..."How long is a piece of string"?
I have one of these devices:
[URL]
Of course, it's Windows only, and XP only at that. However, the data that needs transferred between the device and the computer should be fairly basic, unless it offloads a lot of processing to the computer. I'm not a programmer, nor do I play one on TV, but I have written some fairly complicated microcontroller programs and some basic Java GUIs. Besides writing the actual code, how hard is it to do whatever needs done to make a Linux device driver, apart from the code to make the device work?

Jul 31, 2011I am building a midi synthesizer that I'd like to be able to control from linux. I know its a rather broad question, but, how do I go about this? At this point the hardware consists of a simple UART bridge, and I've already written a simple C++ program using termios to send the raw midi data to the device. Obviously I don't want to write a player/sequencer from scratch, so where should I start if I wanted to get this thing to work with, say, a sequencer like rosegarden? Do I write the driver for rosegarden, or hook into alsa or what?

View 1 Replies View RelatedGeneral :: Uninstall Print Driver To Assure Use Of New Driver?
Jun 21, 2011I would like to know whether an updated print driver has successfully replaced a previously installed driver.
I have a late model Lexmark Prestige Pro805 printer. Lexmark supplies a Linux driver which you download. No drivers appear on the Ubuntu Add Printer list. The Lexmark download also installs utilities, etc. Some stuff appears installed in synaptic. I don't know if uninstalling these only uninstalls the applications and not the actual driver. For some reason, I have had issues recently with this printer malfunctioning frequently with my Linux machines over wifi. They have pushed new firmware down to the printer, and this may be a cause. There is also newer Linux print drivers which I installed, but I do not have a clue as to whether the new drivers are actually in use. On a windows machine I would have uninstalled the printer prior to re-installation. Clueless how to accomplish the same on Ubuntu.
How do I make sure the newest drivers are in use?

View 1 Replies View RelatedGeneral :: Different Write Through Put On The Same Disk?
Apr 5, 2011I am using kernel 2.6.32.21, and my hard disk is West digital WD10EARS-00Y, 1TB. This disk is just for data, I made 2 partitions on it, each has half. And I have another small disk for system. I am using ext3.
this is my fdisk /dev/sdc
Device Boot Start End Blocks Id System
/dev/sdc1 1 60800 488375968 83 Linux
/dev/sdc2 60801 121601 488384032+ 83 Linux
[Code]....
I ran some dd to test the write throughput on /dev/sdc2. If I run it in /data2, I got around 70MB/s. If I create some directory, say /data2/dir/, and run dd again, I might get 60MB/s. Sometimes I still get 70MB/s, sometimes I get 60MB/s, differs for directories.
I wonder if this is because the allocation policy of file system, ext3, or this is from my hard drive?

View 2 Replies View RelatedGeneral :: How To Write Grub On Another HD
Feb 5, 2010I have XP on the boot HD, Ubuntu 8.04 on the other HD, and grub on the MBR of the Windows side. Then the Windows HD went bad and I need to get grub onto the other side so I can change the boot sequence to what was the second HD (the Linux one) and abandon the Windows side. Booting from a live CD is no problem, but I can't figure how to install grub onto the Linux side, which has been partitioned. I know where menu.lst is, and have backups of it as well.
Is this something that needs supergrub, or can a simple write to the proper place be done in a terminal window?
If switching the boot sequence is not enough (don't see why it shouldn't be) then I can also switch the jumper configurations on the two hard disks. But I don't think that should be necessary.
