/dev/sda is suddenly missing and how do I retrieve?
MAKEDEV is not under Darwin why?

Yann,
Thank you. We are addressing that issue.
Kind regards,

[solved] usbstick problem - how to make it /dev/sda

Hi guys,
I have a following issue: sometimes it happens that my younger sister pulls out my usbstick, this causes that it becomes /dev/sdb instead of /dev/sda. The only solution I know to return usbstick to /dev/sda it to restart the computer. Do you know any other solution?

There's this udev trick:
http://wiki.archlinux.org/index.php/Ude … SB_devices
it looks like it will automaticly mount the device to /mnt/usbX . If that won't work you can always modify it to create a symlink from /mnt/usbX to /mnt/usb, or just mount any /dev/sdX to /mnt/usb .
Happy Hacking

Auto Partion fails error = /dev/sda is mounted

I booted from the cd, ran /arch/setup then began going through the setup program
at the point it is going to auto partition my harddrive it fails with /dev/sda is mounted or busy.
I checked /mnt and its not showing anything mounted.
32M for boot
512M for swap
7500 for / and home

Correct me if I'm wrong...I'm stuck at work on a *cough* winbloze machine.
rw=read/write
auto=mount when it boots up
user=users can mount/unmount
sync=write data to the drive immediatly when saved. async writes the data whenever it gets good and ready.
0 0 means the drive will never be force checked.
Or at least one of the 0's does. can't remember for the life of me what the other means.

Cisco Security MARS 110 error - sfdisk:Cannot open /dev/sda for reading

HI when installing the MARS ver 6.0.1 we are getting this error sfdisk:Cannot open /dev/sda for reading, but found that this a bug for that ver BUG id : CSCso92379 - Cannot open /dev/sda for reading" error seen on installing Gen1 GC
So we tried installing the ver 5.3 now also getting the same error, pls let me know is this a hardware issue or a bug

It sounds like there may either be a problem with the RAID controller [configuration] or, though unlikely a hardware failure. You'd need to check the RAID controller BIOS to see if there's a hard disk drive problem or RAID configuration problem. Also check RAID controller is damaged as disks are not recognized at all.
Rebuild the Raid and reimage the appliances.

SATA2 HDD slow based on these hdparm -Tt /dev/sda numbers [SOLVED]

I have a EG45M-UD2H running BIOS F3 (latest one as of the time of this post). I'm noticing a pretty significant HDD speed decrease with this board vs. my old board. If I take the same Seagate 7200.12 (1 gig) HDD and benchmark it on another motherboard, the cached reads are about 7x higher.
For example, under the EG45M-UD2H:
# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 2692 MB in 2.00 seconds = 1346.47 MB/sec
Timing buffered disk reads: 386 MB in 3.01 seconds = 128.13 MB/sec
On another motherboard (DFI LP P35-T2R):
# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 14740 MB in 2.00 seconds = 7378.19 MB/sec
Timing buffered disk reads: 368 MB in 3.02 seconds = 122.04 MB/sec
The only relevant settings I see in the BIOS are:
BIOS settings: Integrated Peripherals>SATA RAID/AHCI Mode [AHCI] <-- I have also set this to disable and there is no difference
SATA Port0-3 Native Mode [Enabled or Disabled] <-- I tried both and there is no difference
Does anyone have any thoughts?
$ lsmod | grep ahci
ahci 34321 4

the 7000mbs cache read, way to high for a sata 3gb interface, so i think the first reading is a mistake.
i dont know of any other hdd test utils apart from dding to /dev/null. but some one will probably mention one soon
Thanks for the info, markp. Can you post the output from your P45 board once you have that system powered up? To answer your question, there's bonnie++ but it takes quiet a long time to run.
EDIT: This whole issue is a non-issue -- PEBKAC. Seems as though I was misusing the -T switch:
hdparm manpage wrote:
-T
Perform timings of cache reads for benchmark and comparison purposes. This displays the speed of reading directly from the Linux buffer cache without disk access. This measurement is essentially an indication of the throughput of the processor, cache, and memory of the system under test.

Dd to /dev/sda instead of /dev/sdb, how to restore /dev/sda

Hello,
yesterday I made a mistake, I did a dd to /dev/sda:
dd if=imagefile.img of=/dev/sda
Problem is my /dev/sda is my harddisk and it should have been /dev/sdb (usbstick).
Now my computer doesn't boot anymore.
How can I restore my harddisk without losing my data? The image file I copied was around 120MB.
Did dd than only overwrite the first 120MB or is there more?
Regards,
Roel

Thank You guys,
my arch-linux is up and running again in aprox. 1,5h time!!
First I tried to backup the harddisk with knoppix and saw my harddisk was empty, in gparted it seemed like it was never used... I was down, down, down... I didn't give up and downloaded systemrescuecd. Testdisk rstored my partition table and I saw it was my lucky day. The first partition on my harddrive was SWAP. All my files where intact and my stupid mistake only overwrote SWAP and MBR.
Reinstall grub would do the trick, i thought... but it didn't. Wy? Testdisk allocated my partitions to hda1 and hda2. In arch I had sda1 (swap); sda2 (/) and sda3 (/home). Now when I reinstalled grub the partition table didn't correspond to the ona in arch. A little bit fiddling in menu.lst, fstab and devices.map managed me to boot my arch system from fallback. My normal boot doesn't work though, I already changed everything to the right partitions but it keeps complaining about not finding my root partition. I already tried root=/dev/hda1; /sda1 and the whole rimram.
Can somebody tell me what's the problem?
It is probably my initrd file, isn't it?

[SOLVED] Arch is on /dev/sdb but I want to remove /dev/sda

Hi. I've got 3 drives in my tower: sda, sdb and sdc. Arch is installed on sdb, but I want to physically remove the drive at sda. When I unplug the drive I get the syslinux menu at boot, but it ends up saying something like
"Root device mounted successfully, but /sbin/init does not exist....You're on your own", and it doesn't boot. If I plug the drive back in, it boots fine.
I'm not sure what's happening here, but I think it has something to do with the fact that I'm unplugging sda, then sdb/sdc get re-mapped to sda/sdb, or something like that. Right now my syslinux.cfg looks like this (note the APPEND root=/dev/sdb1 rw)

I'm tempted to change sdb to sda in syslinux.cfg, and change the UUID=... to /dev/sda1 in fstab, but I don't want to screw with anything boot related since it's a really bad time for me to end up with a system that won't boot.
Am I on the right track here?
If I go ahead and make those changes, unplug the drive and end up with a system that won't boot, can I just go in there with a live-cd, change them back and expect it to boot as before...is that safe?

...by not reading the docs carefully enough...
So you're saying to change my APPEND root=UUID=54ece8c2-8998-4203-b2f8-66cb682e4bf0
in syslinux.cfg
And I should be able to boot with my other drives unplugged?

[SOLVED]ALSA sequencer(/dev/snd/seq) missing = broken midi

I get this error when attempting to start qsynth (frontend for fluidsynth)
fluidsynth: warning: Failed to pin the sample data to RAM; swapping is possible.
fluidsynth: warning: Requested a period size of 1024, got 940 instead
ALSA lib seq_hw.c:457:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory
fluidsynth: error: Error opening ALSA sequencer
It's right, /dev/snd/seq really does not exist on my system. I have the midi driver set to alsa_seq in the qsynth settings, and it's been working just fine up until now. I haven't tinkered with anything related to alsa, so I'm not sure how it disappeared. The only possible cause I can think of is that today I installed kernel26-lts and have been using it for a few hours. However, rebooting and switching to the standard kernel doesn't solve the problem, as /dev/snd/seq is still missing and I get an identical error message. Any ideas/suggestions/wild guesses?

Problems syncing SDA using Missing Sync; Mark/Space support is unhelpful...

I've had a nightmare of a time trying to get my TMobile SDA (smartphone running Windows Mobile 5) to sync using bluetooth (or even the USB!!!) with my MBP.
Can anyone help me?
The crazy thing is that it worked the first time I tried, and then once again in the million attempts I've made, but it won't work anymore, ie the phone and computer say that they're paired but then the phone says "use a computer with Active Sync installed" and the Missing Sync s/w does NOT register or otherwise acknowledge that my phone exists, is hooked up and syncable.
This is REALLY frustrating, esp since it won't even work with the USB connection!!
any suggestions or tales of great success with Missing Sync and the SDA??
MacBookPro 2.16 Mac OS X (10.4.8)
MacPro 2x2.66 // MacBookPro 2.16 Mac OS X (10.4.8) T-Mobile SDA with Windows Mobile/ Missing Sync 3.something

I have Missing Sync working fine with my Cingular Blackjack, which is a WM5 Smartphone based system. There is much written up on this at the Mark Space forums - the major reason why people are having problems is that the phone radio (aka flight mode) must be turned off prior to syncing. This has caused many problems and once you get in this habit, it works reliably every time. The folks at Mark Space are well aware of this and are working on a fix in the future using a different protocol that would alleviate this issue.

Arch Linux won't boot, "working on device dev/sda..."

Everytime I try to boot Arch there is a repeating message that pops up about every 3 seconds after the 'udev' events loads. My boot gets hung on the "working on device dev/sda6 (my linux partition on my laptop) and this message just keeps popping up every few seconds, repeatedly, non-stop:
ata1.00: exeption Emask 0x0 SAct 0x1 SErr 0x0 action 0x0

and after 3 messages like the one above this message appears:

I'm not sure if anyone could help me but I figured I would give it a shot. I might also mention that my HDD has been having tons of issues and has loads of bad sectors, I'm just saving up for a new one but for now I'm dealing with the one I have. My HDD also clicks when these messages start coming up.
Is there any way to fix this?

I might also mention that my HDD has been having tons of issues and has loads of bad sectors, I'm just saving up for a new one but for now I'm dealing with the one I have. My HDD also clicks when these messages start coming up.
LOL. That's like getting to the altar and saying to your soon-to-be-spouse "I might also mention that I'm sterile."
The ata1.00... are hardware errors. Probably drive problems, based on your belated exposition. If you haven't already run a bad sector reallocation tool, do so. The only other thing I would suggest is try the drive on another controller make sure it is only drive problems. I've seen issues on laptops that seemed to be fixed by a new drive, but the problems returned shortly after replacement.

/dev/sda for Arch but /dev/hda for custom kernel. Why?

My laptop does not have a scsi or sata hard drive. So why does Arch's kernel view the drive as /dev/sda1 while a custom kernel views it as /dev/hda like it should?

Hmm that does not at all seem like a good explanation.
Drivers/ide suffers from many ugly and obscure problems, and re-implementing it on top of libata has been much easier than fixing the unfixable drivers/ide mess
you don't think fixing broken and ugly code is a good thing? Let me guess, you think sdxX is somehow more ugly then hdxX?
btw, if you use persistent block device naming scheme, you wouldn't need worry about naming conventions. http://wiki.archlinux.org/index.php/Per … ice_naming

Where are /dev/sda 15 partitions?

I've got a PATA drive, and I installed arch64 half a month ago.
The problem is very easy to understand: my new ArchLinux installation can't detect /dev/sdaX where X>15.
So I can't load /dev/hda16,17,18,19.
How can I fix this?
Thanks

Improve /dev/sda performace

I have a Samsung SATA II HD with 80G.
Which utility should I use, hdparm or sdparm? If it's sdparm, what shoult I put on /etc/rc.sysinit to improve performace?

So? Thanks for the hint, I killed that section.
You don't need hdparm/sdparm at all. See, the kernel takes care of detecting the controller and loading the right modules. And those in turn will detect the drive, its capabilities and set it up accordingly. It worked like that for many many years.
Should your drive not run with DMA enabled after booting, that's most likely a driver bug or hardware issue and nothing hdparm could fix.
For special cases like adjusting power management settings or the like, use /etc/rc.local.

Here is an excerpt of wrong HTML code I see in a forum main page :

The effect is that a column is missing for that line (Subject : /dev/sda is missing in Mac OS X v10.4 Tiger

Yann,
