Installation problems: I/O erro: dev sr0

Hello,

last week I wanted to reinstall Arch on my Laptop (Lenovo Ideapad G580). First I’ve downloaded the ISO and burned the Live CD.
After I choose ‘Boot Arch Linux (x86_64)’ I got this:

Probing EDD (edd=off to disable)... ok

I burned the CD two times and tried it, on a friends laptop. It worked. But my PC doesn’t want to install it.
Now I have Lubuntu on my Laptop
Pls help

Re: Installation problems: I/O erro: dev sr0

Did you check the hash sums of the Arch ISO?

How did you prepare / what medium did you use to install Lubuntu?

Re: Installation problems: I/O erro: dev sr0

I am a bit concerned about those I/O errors. You say the same CD works on your friends machine?
What media are you using? You might try a CD-R instead of a CD+R or a CD RW. Avoid DVD media all together.

Is booting from USB an option? Is booting from PXE (network boot) an option?

Re: Installation problems: I/O erro: dev sr0

There is a similar thread about this. (https://bbs.archlinux.org/viewtopic.php … 3#p1516893
I’m wondering if there is a wider problem to this. As the I/O errors appear on exactly the same sectors I doubt that two people have exactly the same CD or CD-Drive with exactly the same error. This would be rather unlikely.
Or is there another explanation for this?

I put at button on it. Yes. I wish to press it, but I’m not sure what will happen if I do. (Gune | Titan A.E.)

Re: Installation problems: I/O erro: dev sr0

Thank you for the answers. The hash sums are ok. I’d install Lubuntu from USB, but I didn’t tried it with Arch, because I had a few Problems when I tried it the first time and so I installed it with the CD. The CD I used a year before (when it worked) and the CD I used this time are identical. The CD from the first install, doesn’t work anymore, too >.<
I will try to install debian from another live cd. Only for a try.
After that, I will try to install from USB. Perhaps it will work.

Is this disk you will burn yourself or disc from the front of a magazine? (for example)

There are several possible scenarios going on which would be nice to resolve before it comes back to bite you later

1) CD drive faulty or failing
2) CD discs faulty, incompatible or inconsistent
3) ‘Current Arch ISO is failing to write correctly on some hardware/software combinations… unlikely as the board is not flooded with the error you are reporting but not impossible…

Would be nice to know as the other post linked above left quite a few questions unresolved

Re: Installation problems: I/O erro: dev sr0

I’m having the same I/O Erro on exactly the same sector.

ISO md5sum was checked after download.
ISO was burned to a CD using Brasero
The disk is labeled ARCH_201504

Trying to install on a fairly standard HP laptop from the last 3 years.

So, looks like it could be option 3 in the previous post?

Re: Installation problems: I/O erro: dev sr0

I also had this I/O error yesterday. But for me it was sector 1227352

My steps were as follows:
1. Downloaded archlinux-2015.04.01-dual.iso
2. Verified MD5
3. Burned CD-R (with a verify after burning) selected x86_64 from the bootmenu and had these I/O errors on dev sr0.
4. Burned DVD-R and it worked fine.

Which rather points the blame at the media/software/hardware/user not the ISO itself.

Re: Installation problems: I/O erro: dev sr0

Update: I encountered this myself this weekend. I obtained a new laptop with Window 8. After checking everything for proper operation, I downloaded and burned Arch to a CD-R from Windows 8 on my new machine. When I tried to install using that disk, I encountered the exact same problem described here. As a control, I tried a second disk. Same thing.

Went to my old machine running Linux. Downloaded and burned using Linux. Moved the disk to the new machine and it worked perfectly. Installed Arch on the new machine and then used the new machine to burn a disk using Arch Linux. The disk worked just fine.

Looks like a Windows bug. I’ll not be filing a bug report with Redmond.

Re: Installation problems: I/O erro: dev sr0

Having the same error.

Downloaded the archlinux-2015.04.01-dual.iso via torrent. Checked the MD5 sum. «burned» it on a brand new blank USB with Unetbootin.
Have gone over the process of formatting the USB twice and «buring» the iso on it with unetbootin twice. Same error.

Your problem is different: the OP is referring to a CD/DVD whilst your situation involves a USB stick.

Try transferring the ISO image using the `dd` command (as per the Beginner’s Guide) rather than unetbootin

If it still won’t work you should open your own thread and link back to this one.

My bad. The `dd` command solved it. Thx and sorry for the trouble.

Not unless the ArchISO is created on a windows box???????? At least one of the posts above mentions burning with Brasero… which has always been pretty random IMHO…

Re: Installation problems: I/O erro: dev sr0

You are right. There were some postings to the mailing list about issues with Brasero as well. I don’t understand what you mean by «Not unless the ArchISO is created on a windows box?» What I am saying is that when I downloaded the binary and burned it using Windows 8’s intrinsic tools I encountered the problem. When I used wodim on the same computer and drive, I was able to burn a usable disk. My assumption is that I am not the only one who has tried to burn a disk using Windows — most desktop and laptop Linux machines are born-again Windows boxes.

I see the same CD errors trying to use archlinux-2015.04.01-dual.iso to reinstall Arch in an old P4 (Celeron) machine:

MD5 and SHA1 sums checked.
ISO burned in two CDs at different speeds via Brasero under LMDE: unable to boot from both disks.

BTW: archlinux-2015.03.01-dual.iso works fine for me…
Booting from 2015.03.01-dual.iso, I’m able to arch-chroot in the previously installed Arch and perform commands as root (including full update).

Seemed to be a bug in archlinux-2015.04.01 ISO creation.

Any suggestion?

Re: Installation problems: I/O erro: dev sr0

EDIT:

@ewaller: you’re right!

It’s a Brasero related bug
Using wodim (command line) to burn archlinux-2015.04.01-dual.iso makes a fully bootable CD

Best regards,

Re: Installation problems: I/O erro: dev sr0

Hi, sorry for bumping this relatively old topic but I’m running into the same issues on two separate machines.

ISO: archlinux-2015.10.01-dual
HASH: MD5 verified
Burn application: https://cdburnerxp.se/en/home (using data verification mode)

I’ve burnt the disc twice to make sure the disc itself wasn’t to blame.

The I/O error occurs on the same sector between both discs on both machines!

To me this indicates a burn / media issue, but data verification completed perfectly?

Dumping the exact same image to USB and booting off that throws no issues.

Inserting the CD in a booted live environment instantly throws the same I/O error. Inserting some other burned discs also result in I/O errors, though not all. Non-burned media seems allright.

Re: Installation problems: I/O erro: dev sr0

Switched to http://www.imgburn.com/ and suddenly both systems boot perfectly off the newly burned media.

Going to do some more verification, check discs against each other and the like. The burner application seems to have been the cause.

*edit*

Odd, the install media has the exact same MD5 sum. I’m at a loss for words here.

Re: Installation problems: I/O erro: dev sr0

Hi all,

I realize this is an old post. Yet, trying to burn the latest iSO — having md5sum-checked the iso after download — having burt with both brasero and wodim, I have the same problem.

Same error messages as below, just a different sector number.

I am side stepping this problem now by trying to install from a knoppix live distro — which boots perfectly by the way — even if burnt with brasero.

Burning on Ubuntu 15.04

Anybody knows what I causing this?

Regards

Frank

Re: Installation problems: I/O erro: dev sr0

I’d just like to confirm that after an identical problem trying to install from a CD, Lone_Wolf and LK’s solution of burning the disk using SAO(DAO) mode worked for me. Many thanks; I don’t think I would ever have sussed that one out on my own.

Recently, I’ve been seeing error messages in my syslog saying «Buffer I/O error on dev sr0». This has happened around the same time my game emulators are running worse, so I think they’re related.

It could slow startup times however, if the software is waiting for the bad reads to come back… Could see if it’s any different with a disk in the drive, but there likely is a rogue blkid command scanning all your mounted disks and tries to read the optical drive… at least that’s what’s happening on my machine. _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD What am I supposed watching?

Well, after some updates and removing some unused packages, and leaving a disc in the tray, I can safely say this issue is fixed.

TBH leaving discs in the tray is a nasty workaround but if you just don’t want to see that error, good enough. BTW another possibility is lvm scanning your disks. Though it’s possible to use a CD or DVD or BR disk, it’s probably not a good idea and perhaps it should be told not to scan them. Then again I think I’ve heard people making a RAID of floppy disks drives… _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD What am I supposed watching?

I’ve just realised that I’ve seen this problem before — over a year ago, this thread. The fix that Red Hat claimed to have made doesn’t appear to work. The trick with a disk in the drive looks to be a useful bypass. But I just ignore the problem…. _________________ Greybeard

Hmm… interesting. I have removable media drives in many of my machines and recall just one that has this issue. The only thing special about that machine is that it has a «part time» RAID on it (as in, I have RAID disks attached to it but don’t use it all the time, generally leave it unassembled.) I did realize on that machine that «blkid» triggered a read on an empty drive, but it might have been the floppy drive that it was trying to read and causing errors, not an optical drive…come to think of it, that machine doesn’t even have an optical drive… Since the OP is seeing this 150 seconds after powerup it’s likely that it’s due to the desktop environment file manager or perhaps even wine with udisks, for whatever reason, wanted to peek at the optical disk. Perhaps an old link to the drive somewhere it’s trying and failing to read. _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD What am I supposed watching?

Hmmn, my machine has a RAID array, always assembled, calls mdadm to create it during the initramfs. I wonder if RAID support is enumerating potential members or something. I’ll have to check my desktop machine’s mdadm.conf to see if it’s scanning or something. LemonadeLlama, does your machine have RAID? _________________ Greybeard

Are you asking me if I have RAID support in my system, or if I am currently using RAID storage?

Как правильно задавать вопросы

Правильно сформулированный вопрос и его грамотное оформление способствует высокой вероятности получения достаточно содержательного и по существу ответа. Общая рекомендация по составлению тем: 1. Для начала воспользуйтесь поиском форума. 2. Укажите версию ОС вместе с разрядностью. Пример: LM 19.3 x64, LM Sarah x32 3. DE. Если вопрос касается двух, то через запятую. (xfce, KDE, cinnamon, mate) 4. Какое железо. (достаточно вывод inxi -Fxz в спойлере (как пользоваться спойлером смотрим здесь)) или же дать ссылку на hw-probe 5. Суть. Желательно с выводом консоли, логами. 6. Скрин. Просьба указывать 2, 3 и 4 независимо от того, имеет ли это отношение к вопросу или нет. Так же не забываем об общих правилах Как пример вот

С очень большой вероятностью, тут проблемы с диском на аппаратном уровне. В гарантию/ремонт/мусорку. В любом случае, сначала нужно проверять железо.

Отнести в сервис. Особенно, если на диске есть что-то ценное.

Но если удается загрузится в какую-нить линукс-систему, можно предварительно глянуть SMART:

smatrctl -a /dev/sda

(Вместо /dev/sda — имя диска в системе.) В ответ будет большая простыня из которой, в принципе, можно извлечь много информации о состоянии диска. Но тут в двух словах не расскажешь — оно комплексно анализируется.

Или запуститься с флешки в live режиме и в консоле выполнить команду: sudo fsck -M -y

Для диска с подозрениями на аппаратные проблемы — совет откровенно вредительский.
Не в коем случае, никогда не пытайтесь лечить структуру файловой системы если нет уверенности что аппаратно диск полностью здоров. А то потом вам данные с такого диска даже в сервисе не спасут.

Только начинаю устанавливать, как появляется водопад таких сообщений:
…Buffer I/O error on device sr0…
До этого ставил Ubuntu 8.04 — всё работало.

Gigabyte P35-S4
Жесткий диск SATA, привод IDE.

Проверял на старом ноутбуке — всё установилось.

asashnov

sr0 это CD-ROM:
ls -l /dev/sr0
lrwxrwxrwx 1 root root 4 2008-11-29 15:37 /dev/sr0 -> scd0

Попробуй «Check Media» из загрузочного меню.

С этим разобрался. Поставил noapic и загрузился с LiveDVD.
Потом с LiveDVD установил Ubuntu на жесткий диск, но после установки при перезагрузке системы (окончательный этап загрузки) появляется окошко с ошибкой драйвера nVidia. Закрываю это окошко, и система зависает с черным экраном. В логах x.org в самом конце написано что то типа этого:

(EE) NVIDIA(0): Failed to load the NVIDIA kernel module!
(EE) NVIDIA(0): *** Aborting ***
(II) UnloadModule: «nvidia»
(II) UnloadModule: «wfb»
(II) UnloadModule: «fb»
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found

Lirck

Вообще странно, когда поставил noapic пошла установка. Сейчас проделываю тоже самое — опять эта ошибка Buffer I/O error…

Lirck

Попробуй «Check Media» из загрузочного меню.

Не вижу в этом смысла, так как на другом компьютере всё установилось без проблем.

У меня была такая проблема, причем на нескольких компах.
Это что-то связано с компоновкой CD-образа.

Решилась это проблема просто. Я взял тот же самый образ CD-диска, но записал его не на CD-болванку, а на DVD. Все заработало на отлично.
Откуда этот глюк — не знаю до сих пор.

Вроде должно помочь, но нав всякий случай проверь вначале на DVD-rw болванке.

Можно еще попробовать установить с флешки, если есть. 1 Гб хотя бы флешка нужна.
UNetboot софтинка, которая под виндой или linux закидывает файлы из .iso образа на флешку.

Всем привет! все жизнь сижу на Винде. наслышан и линуксе и решил всетаки перейти на линукс. скачал с офф сайта ubuntu 8.10 также взял у знакомых ubuntu 7.10. ставлю на ноут hp compaq nc6120. при установке любой из версий вылезает Ubuntu 8.10 Buffer I/O error on device sr0…
я так подозреваю что это из за привода. хотя работает он исправно.
наставьте новечка на истинный путь ) подскажите может есть какой то другой метод установки линукса.
ЗЫ хочу поставить его на винт на котором было 2 лог. раздела и стояла винда. снести все к чертям и поставить ubuntu. к сожелению нечего не получается(((
ПОМОГИТЕ.

Была у меня такая проблема.

У меня в системном блоке стоит два винта (sata) и два cd-rom один IDE второй SATA. Выскакивал такой глюк Buffer I/O error on device sr0… иногда система даже не загружалась и падала в {DRDY error}. Я отключил в БИОСе IDE CD-ROM и теперь все работает как часы (кроме одного привода соответственно )

Дело в том что ставлю я на НОУТБУК HP compaq nc6120.
вот описание железа:
Чипсет   Intel 915GM
Процессор    Intel Pentium M processor 750 1.86 ГГц
Оперативная память    512 Мб DDR333
Жесткий диск 80(5400 оборотов)
привод встроеный DVD-RW

OH

Можно еще попробовать установить с флешки, если есть. 1 Гб хотя бы флешка нужна.
UNetboot софтинка, которая под виндой или linux закидывает файлы из .iso образа на флешку.

нашел софтину, загрузился с флашки. вышло консоль где написанно (initframs) и ждет команды. что туда вводить чтобы установить линукс??7

asashnov

вряд ли что поможет туда ввести
Это означает, что мизерная система на initramfs не смогла отыскать раздел с указаным UUID (он пишется в самом начале, booting from … ).
Версия ubuntu 8.10, не ниже?

Talk is cheap. Show me the code. (c) Linux Torvalds.

I have Ubuntu Server 20.04 installed in virtual machine on my Windows Hyper-V host.
I’d like it to get IP address from my Windows DHCP-server in local network
But it doesn’t work and I don’t know why. Virtual machine with Windows with same configuration works fine.

[SOLVED] Buffer I/O error on device sr0

Buffer I/O error on device sr0

Let me see if i can best explain my dellima. Long story short, it all started when i typed «sudo rm -rf /lib» in the wrong ssh session.

After this mishap I went to reinstall ubuntu from the live cd, *the same cd i did last install on this machine with*

The live cd opens up, lets me select ‘Install Ubuntu’ Then… i get this madness.

[4.370442]end_request: I/O error, dev sr0 sector 40
starting system log daemon: syslogd, klogd

After this message the installer loads and I follow through prompts and I have gotten several errors «Kernel Panic, Must restart», «Unable to mount CD-Rom», «CD does not contain a valid ‘release’ file».

Ive been reading forums all day long and have tried a ton of things, the following.. all have failed.

1. Downloaded fresh copy, verified md5sums, burned cd, verified md5 — fail
2. pressed f6, tryied with noacpi — fail
3. pressed f6, tryied with all_generic_ide=1 — fail
4. pressed f6, tryied with noacpi=off — fail
5. Switched drives — fail
6. Switched IDE cable — fail
7. Took HDD out and formated drive, retried — fail

Anybody know what else I can try?? Oy vey!

Re: Buffer I/O error on device sr0

Hi mattgyver83.

Your CD may be scratched, etc.

Try burning a new one, and burn at the slowest possible speed.

Re: Buffer I/O error on device sr0

Thanks for the reply. I actually have done this and made 3 different copies, the slowest my burner can burn is at 16x, same problem with those as well

Are you using rewritable disks?

Re: Buffer I/O error on device sr0

maybe your drive is starting to fail?? For two weeks I tried burning some dvd’s, all failed and I didn’t now why. After thinking about it, the disks looked and worked ok on other PC’s, but wouldn’t mount on mine. Changing the drive did the trick. Seems mine wasn’t OK anymore.. I don’t use it much and it has a year or so. I had bad luck I guess
Re: Buffer I/O error on device sr0

Yes, i am using rewritable discs, and they are Sony discs there not just cheapo discs. Just a side note i am not trying to re-write over any existing cds, these are all fresh burns.

As well this machine has 2 cd-rom drives and to test if it was a bad drive I switched the other drive to master and still had the same problem.

Whats puzzling is that I have other live cds that will work in the drives :

I’ve had some problems with CD+RW discs, but CD-RW usually work very well.

Re: Buffer I/O error on device sr0

I have one copy on cd-rw, that was a reburn copy after i downloaded the image again. The first cd I used (original) was just a cd-r, so are 2 other cds that I freshly burned.

Just to humour myself I went out and bought a brand new dvd/cdrom drive. I will try these with this drive and see if they work, even try a dvd burn.

Ill keep posted, thanks for your comments.

Re: Buffer I/O error on device sr0

Well, this can gladly be marked as solved. The new drive works and the OS has been reinstalled.

I guess my drives were just beginning to fail, they are rather old. If anyone is able to offer information as to why some CDs would work with these 2 drives until now that would be great, id like to answer that enigma.

Well, to all those who responded thanks a lot, and to every one else reading this…. moral of the story.. Check your SSH sessions at the door sudo rm -rf /lib = bad.

Until i break something else… fin.

I got a Thinkpad R61 with a Matshita drive and, as the title says, I cannot play audio CDs. After inserted a CD, syslog shows:

I did’t know if this is an hardware issue so I tried an external dvd drive but I got the same errors.
To play CDs I tried different programs: xmms2, cdcd, mplayer and sound-juicer and different cds (all original if this matter) but without luck.

I also tried a different kernel version, actually I’m using a custom one, using a debian precompiled ones (package linux-image-2.6.32-5-amd64) but again without luck.

Here a relevant kernel configuration:
