But before that, open 'Disk Utility' and check whether the pendrive is present. If present you could format and partition from that application itself. If the device is not found in 'Disk Utility', you will have to format using the command: dd if=/dev/zero of=/dev/sd(x) where (x) can be b, c, d etc. Care is to be taken as selecting the wrong device can even endup formatting your harddisk. If your pendrive have a led indicator, it must indicate that the device is busy when the above command is executed. share|improve this answer edited Feb 10 '15 at 2:12 muru

-bash: /etc/profile: Input/output Error Ssh
a seagate 250 GB hard drive.I have been trying to install Ubuntu Netbook 10.04 from my flash drive ( tried with CD too...no luck ).The boot order is set to detect USB first. http://askubuntu.com/questions/423853/cannot-create-a-partition-table-on-dev-sdb This is the error message I get "Input/output error during read on /dev/sda" while installing Ubuntu 10.04 on my hard drive. On clicking Retry, The installation shows 15 % completed and returns another error " The ext4 file system creation in partition 5 of SCSI (0,0,0) (sda) failed. The Ubuntu runs perfectly from the pen drive and the disk utility which I ran from Ubuntu showed my disk https://forums.techguy.org/threads/solved-input-output-error-during-read-on-dev-sda-on-installing-ubuntu-10-04.977983/ as healthy ( the utility was not able to format the hard drive either... ). I was able to install windows XP on the same hard drive later after formatting it.It seems there is nothing wrong with my hard drive as even running chkdsk didnt bring out anything.I am not sure if I missing out anything here...any help would be much appreciated.

Ubuntu 10.10 (Maverick Meerkat) is the latest version available until April when a new release 11.04 is scheduled. Prior to attempting to install Ubuntu, it is necessary to create a partition on your disk. If you entire disk is already formatted for WinXP on an NTFS file system, you need to repartition the disk and create at least say a 10-20GB or more partion for EXT4 in which to install Ubuntu. If you don't setup the EXT4 partition prior to attempting to install Ubuntu - that could be the cause of your I/O problems. From what you describe, I would boot up from your USB, and then use the GParted partition editor to repartition your 250GB harddrive to

I couldn't copy anything to it (copy operations hung indefinitely then ended with IO error), so I tried reformatting it via the GUI. It now appears to be formatted as EXT4. Unfortunately, I still couldn't copy things to it. It formatted suspiciously fast (a few seconds; it's a 1TB drive). So I figured maybe it formatted wrong. So I tried: $ sudo fdisk /dev/sdb1 and got: fdisk: unable to read /dev/sdb1: Input/output error What do fdisk unable to I do?! I'm in Ubuntu 12.10 in case it matters. linux ubuntu hard-drive share|improve this question asked Jul 4 '13 at 12:26 Hut8 158128 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote fdisk works on disks, not partitions. On Linux, a disk is referred to as e.g. /dev/sdb, whereas the partitions on it are referred to as /dev/sdb1, /dev/sdb2 etc. Note that old-style (/dev/[hs]d?, /dev/[hs]d??) partition specifiers always end with a digit, whereas disk specifiers always end with a letter. If you just format the disk (no bad blocks checking etc.), then a format time of a few seconds is not entirely unreasonable. All you did was write the initial file system metadata structures to disk, and while I don't have any exact numbers to cite, those are fairly small, and USB is pretty fast for writing such relatively small amounts of data. If you didn't get any errors, the format process probably did its thing. The first thing you should do is run fdisk on the proper device. In your case, it sounds like that will be sudo fdisk /dev/sdb, but note that in some cases the device name can change with time. I recommend using one of the entries in /dev/disk/by-id instead, as those will not change. You can see what the disk shows up with there by running, immediately before you connect the disk: diff <(ls /dev/disk/by-i
