The drive isn't reading discs. Dmesg says PIO255(auto-tune) requested, PIO4 selected, UDMA33MHz.
An inexpensive drive with many failures noted on Google.
What command would I enter in grub following "ro quiet" to change the mode?
Installed Ubuntu 10.10 this morning from CD, downloaded all the latest updates. But when I put a CD or DVD in the drive, I can't access any of the data. Disk utility recognises that the drive is there, but it says "No medium detected".
Disk utility recognises it at /dev/sr0 so I added a line to fstab
/dev/sr0 /mnt/dvd udf,iso9660 user,noauto,exec 0 0
but made no difference
I've installed libfuse2 and ntfs-3g. Now when I reboot, the drive shows up in fdisk. In Gnome File system, the folder shows up in /media as /media/Storage. I didn't issue the mount command, it went there automatically. In terminal, I can access Storage and read/write to files on it. BUT, if I double-click the folder in Gnome, I get a brief glimpse of all the folders in Storage, then they disappear and the drive unmounts. The desktop icon goes away, and I can't see it when I issue sudo fdisk -l. I can get it back with a reboot. I've tried an entry in /etc/fstab, but that makes no difference. I didn't find anything specific to address this on this forum or after Googling.

Another thing is that after reading from the server's HDD, it seems to write on the desktop's SSD. It does this intermittently.I really want to know how can I stop this. It's very annoying and I bet I don't need it since, using previous versions of Debian, I could go well without this activity.

I know the drive is hooked up via SATA.
It has worked before, and I have no idea why it isn;t working now. And I have made no BIOS changes since it worked once. The only change is I installed the newest kernal, that I can think of.
I ran accross someone asking someone with a similar problem to run:
ls /dev | grep cd
so I did and I get: andrew@andrew-desktop:~$ ls /dev | grep cd pktcdvd
seen this or have suggestions on how to fix this. I can read the original disks but I cannot read the backup. The backup disc was burned on Window$ using Nero.I am trying to read the disc using both VLC and Totem but you can see in /var/log/messages there is an issue with reading the disc. This disc is readable in the Window$ box and on all DVD stand alone players.

1) When it gets to the "reading and comparing" phase, it seems to complete in <1s. I see other posts where people say this takes them as long as it took to write to the drive. I don't see any mention of this being quick, so I'm just afraid that badblocks is being denied read access or something.. Anyone familiar with this behaviour?
2) Obviously since it is on a sixth pass, badblocks thought that it found new bad blocks on the second pass (or later). When I check SMART, though, the drive has not re-allocated anything (despite having plenty of spares)... Doesn't this seem odd? Is there some reason why the disk would not step in upon a write fail? In fact, I thought a write fail should be transparent... Which makes me wonder if question 1 (above) is causing this...
I just downloaded the Fedora11 LiveCD and booted it......it boots, but when it starts to load KDE, it takes a very long time, and it never ends. It just keeps on reading from the CD-ROM drive. I can see the GUI is loading, but the loading time is so long that the mouse sometimes freezes. My Config is 512MB of RAM and 2 IDE Hard Disks. Also note that I verified the image with SHA256, and even burnt the CD at two different speeds, one at 48X and the other at 16X. Still nothing. There has also been severe kernel panics on EXT4.
View 2 Replies View RelatedI need to read some data from a hdd that belongs to an old SCO Unix system. The SCSI card is PCI so I unplugged it from the old SCO unix box and stuck it in a new computer and booted using a Fedora 14 USB pen drive. The SCSI card was recognized and so was the hdd but it was not mounted. I then went into Applications, Disk Utility, and found the hdd. Under 'Edit Partition' the type was blank. I was tempted to set it to 'Extended' but was not sure whether that could damage the data on the disk. Does anyone know whether I would be able to read this Hdd by setting the type to 'Extended'?
View 5 Replies View RelatedI decided to install Maverick on another PC in the house. I downloaded and burnt the 10:10 live CD three weeks ago and installed it on my laptop without problem.
Now when try to install on this it read the CD as first boot device, goes to the language selection, and then the "try without installing/Install/check disk" etc. I select either "install" or "try without installing" and after s few seconds the drive spins down and thats it...nothing more happens.
I know the CD's fine as I already installed with it and the PC in question currently has a working version of Karmic on it. PC is an Acer L100 and the CD is the 32 bit version.
Update: After posting this I've played around a bit more. It seems most attempts it doesnt want to read the Live CD at all. After trying to boot from it and displaying the copyright line "isolinux..." it jump straight GRUB and boots my present OS. I've just tried the Karmic CD too and the same thing is happening. So maybe points to a problem with the CD drive??
I wish to read the Manufacturer data and other details such as Device ID, Serial number on a USB drive.
1. Could anyone help me out with information on the memory structure of a USB drive? (which location is the mnfr data stored?)
2. Are there are any commands in Linux that will help in reading/accessing this data?
I wanted to check the first sector of my USB stick, and so I issued:dd -if=/dev/sda -bs=1024 -count=1It showed me all the weird characters from the data, then after it executed my bash prompt became corrupted with the same kind of characters! Also, everything I typed was like that. (see the picture)Luckly, it was just that tty that became like that.How can I fix the fonts after something like that happens, and how to prevent it from happening whenever I use dd again?

I have been backing up onto a 60G ext2/3/4 partition on a 1TB external USB hard disk for a year or so now and have built up a few folders of .thunderbird, .mozilla, and other assorted files - using this as my standard "backup system" - but suddenly all the files and folders in this partition seem to have disappeared.
In Gparted and KParted the partition shows up as the correct size with the correct amount of "used space" (= yellow coloured portion), as it does when running offof any CD/standalone OS. And the small bars under the volume names in Dolphin show about the right amount having been "used" too.But however I try to access this partition (or, to be correct LVM I spose:-)) it still always comes up as empty - ie 0 files in it. After months of working just fine.The NTFS partition on the same external USB sdd reads and writes quite OK/normally and also shows the correct amount of "used space" - but even from root I can't see any of the old files in, or read/write to the linux one. It comes up with "Denied"/"Can't Write to.." errors when trying to write anything to it.
I ran a freeware utility called DiskInternals Linux-Recovery from winDoze which, after half an hour, came up with a list showing all the folders and files in the partition. It said that they would be written back onto the hard drive that they were "retrieved" from - but no change happened - still no contents showing when booting up in any linux.

I don't understand the results of a simple performance test I ran using two basic scripts (running on a high end server):
perfVar.zsh :
#!/bin/zsh -f
MYVAR=`cat $1`
for i in {1..10}
[code]...
Performance test result:
> time ./perfVar.zsh BigTextFile > /dev/null
./perfVar.zsh FE > /dev/null 6.86s user 0.32s system 100% cpu 7.177 total
> time ./perfCat.zsh BigTextFile > /dev/null
./perfCat.zsh FE > /dev/null 0.01s user 0.10s system 91% cpu 0.118 total
I would have thought that accessing a VARIABLE was way faster than reading a FILE on the file system... Why this result ?Is there a way to optimize the perfCat.zsh script by reducing the number of accesses to the file system ?

I am using a backup system with cron + tar. Since the server is very busy, I get often the cron-email: "The file XYZ has changed while reading". This message is a bit annoying and I see it as critical point in my backup system. I believe that this file is then not in my backup. (Is that correct?) Let's imagine the hard disk dies and I have to recover the system and my personal data, and in the night the mysql-table XYZ was not in the backup, because it was in read-usage. I would then have lost this table forever. Is there any way to tell TAR, that it should force the file to be included (if in read-usage, then wait 2 seconds and try again)?

View 6 Replies View RelatedI've installed Lenny a few times before, but something is going wrong here this time. I couldn't remember the exact method I used to put an image on a disc, but I tried over 10 ways, and every time, after starting up, it says something along the lines of please select different boot device or insert bootable disc and press a key. There's a bunch of options to make these images in Windows apps, but I did one solid way that should have worked i believe.
This was to zcat boot.img.gz > /dev/sdx and so on, then copy the mini.iso to the usb drive (instead of previously making cds). I thought maybe my cd drive wasnt working, but the usb drive, when selected as primary boot drive had same issue. I didnt see any errors in its creation on the usb drive either. Running AMD64, have three hard drives plugged in, thought maybe the newest drive had an issue, so I tried different combinations of unplugging power and data cords of each and once all hrd drives. Using this computer right now, actually, XP is running. A command prompt version of squeeze is installed, its having some difficulties, thats why i would like a new install.
