  • How to write image of a floppy disk to a flash drive?

    - by Usman Ajmal
    I have created an image of a floppy disk by executing: dd if=/dev/fd0 of=/home/myFloppy.img My floppy disk is no more working now. So I am thinking now if it's possible to write the image of that floppy to a flash drive and then i may boot my machine from the flash drive. My machine's BIOS has the option of 'Boot from USB'.

  • Mounting a usb floppy disk drive in Ubuntu 11.04

    - by Jocky B
    I have tried to mount my usb floppy disk drive in 11.04 Natty. So far I have managed to use the udisks --mount/dev/sdf command in terminal, but get a message that I have not stated a filetype "john@john-desktop:~$ udisks --mount /dev/sdf Mount failed: Error mounting: mount: you must specify the filesystem type" This is the result I get when trying to mount the usb floppy disk drive. Anyone know how to proceed Cheers

  • Need to get a file written to a floppy.

    - by dboarman-FissureStudios
    I asked this question over on SO. I have tried dd if=kernel.sys of=/dev/fd0 bs=512 seek=1 to get this file to write to the floppy. It is a kernel shell that must be written to the sector immediately following the bootsector of a disk to boot the PC. No matter what I've tried, for some reason, kernel.sys is not writing to the floppy. I know the bootstrap loader is being written and executed. However, it cannot find the kernel to load the shell. Any ideas on what I am doing wrong? I mean, really, how is it so difficult to get this file written to a floppy? OpenSUSE 11.2

  • Somebody knows why the sectors of the IBM floppy disk are named 1 to 8 (and not 0 to 7 )

    - by Olivier Briand
    I am now programming on a 8 bits Z80 computer with CP/M 2.2, (as a hobby) and the floppy disk format is IBM, 40 tracks, 8 sectors per track, 512 bytes per sector. free space is 154 Ko on each face of the disk. Why the sectors are indexed 1 to 8 (and not zero to seven, as usually is seen with computers)? The catalog of the floppy disk is on the track 1 (sector 1 to 4, 64 entries). I'm wondering is the catalog on track zero? Is the zero track reserved to included a system (as track 0 & 1 are reserved to the system on a CP/M floppy disk, and catalog is on track 2)?

  • Windows 2008 Unknown Disks

    - by Ailbe
    I have a BL460c G7 blade server with OS Windows 2008 R2 SP1. This is a brand new C7000 enclosure, with FlexFabric interconnects. I got my FC switches setup and zoned properly to our Clariion CX4, and can see all the hosts that are assigned FCoE HBAs on both paths in both Navisphere and in HP Virtual Connect Manager. So I went ahead and created a storage group for a test server, assigned the appropriate host, assigned the LUN to the server. So far so good, log onto server and I can see 4 unknown disks.... No problem, I install MS MPIO, no luck, can't initialize the disks, and the multiple disks don't go away. Still no problem, I install PowerPath version 5.5 reboot. Now I see 3 disks. One is initialized and ready to go, but I still have 2 disks that I can't initialize, can't offline, can't delete. If I right click in storage manager and go to properties I can see that the MS MPIO tab, but I can't make a path active. I want to get rid of these phantom disks, but so far nothing is working and google searches are showing up some odd results, so obviously I'm not framing my question right. I thought I'd ask here real quick. Does anyone know a quick way to get rid of these unknown disks. Another question, do I need the MPIO feature installed if I have PowerPath installed? This is my first time installing Windows 2008 R2 in this fashion and I'm not sure if that feature is needed or not right now. So some more information to add to this. It seems I'm dealing with more of a Windows issue than anything else. I removed the LUN from the server, uninstalled PowerPath completely, removed the MPIO feature from the server, and rebooted twice. Now I am back to the original 4 Unknown Disks (plus the local Disk 0 containing the OS partition of course, which is working fine) I went to diskpart, I could see all 4 Unknown disks, I selected each disk, ran clean (just in case i'd somehow brought them online previously as GPT and didn't realize it) After a few minutes I was no longer able to see the disks when I ran list disk. However, the disks are still in Disk Management. When I try and offline the disks from Disk Management I get an error: Virtual Disk Manager - The system cannot find the file specified. Accompanied by an error in System Event Logs: Log Name: System Source: Virtual Disk Service Date: 6/25/2012 4:02:01 PM Event ID: 1 Task Category: None Level: Error Keywords: Classic User: N/A Computer: hostname.local Description: Unexpected failure. Error code: 2@02000018 Event Xml: 1 2 0 0x80000000000000 4239 System hostname.local 2@02000018 I feel sure there is a place I can go in the Registry to get rid of these, I just can't recall where and I am loathe to experiement. So to recap, there are currently no LUNS attached at all, I still have the phantom disks, and I'm getting The system cannot find the file specified from Virtual Disk Manager when I try to take them offline. Thanks!

  • IBM Thinkpad 240 - Best way to boot from floppy to USB - Best Linux for 300 MHz 128 MB RAM 800x600 s

    - by zillion
    Mostly I still have that old 'ultraportable' laptop that is mostly like a pre-netbook era laptop and a friend and programmer needs a computer because the one he was using just broke and he has to wait until the new one arrive in 4-6 weeks ... This laptop has no LAN connection and CD-ROM so be prepared for a real challenge! All hardware is well supported on Windows XP (included drivers on the Windows XP CD) and on Linux out-of-the-box (but the screen need a special configuration.) Mostly any Linux that will work well with Skype (USB or regular headset), any MSN client and a text writer for code will do. What I have tested so far: Slitaz 2 don't boot because the floppy of GRUB4DOS don't see the USB drive (fully working and tested on my regular laptop), Damn Small Linux was working but was needing a special screen configuration that I don't remember (in the boot options of the floppy) and now I'm thinking about Puppy Linux that is seen to work totally out of the box with it but I will need an old Puppy version (1 or 2 I think) and the Wakepup floppy ... If you got some ideas to help or to try I'm open!

  • kickstart: reference floppy drive via %ksappend or %include

    - by virtualeyes
    Having trouble getting %ksappend or %include to work when referencing a local floppy drive. Booting off remote server's cd-rom drive I am able to load the CentOS 6 minimal install image, and then add ks=hd:fd0/ks-jvm.cfg to boot params to load kickstart init file from floppy disk. That works fine. The problem is that I want to load a streamlined generic init file off the floppy and then, within the init, %ksappend or %include specific config files relative to the type of server I'm building (JVM, MySQL, Apache, etc.) I do not have DHCP, networking needs to be specified statically, so %ksappend and %include both fail when attempting to reference http://some-LAN-IP/foo.cfg since networking has not yet been set. The kickstart setup only works when I glob in the entire config into a single file, which is great, but ugly and difficult to maintain when I return later, having forgotten the original setup. At this point I'd be happy if I could get %ksappend or %include working with a floppy drive reference in the %post section; that would consolidate a lot of common boilerplate that all kickstarts will rely on (sshd_config, rsync config, resolve.conf, and so on) Thanks for providing the magic floppy drive reference that is eluding me!

  • Can a Double-Density Floppy drive be swapped out for a High-Density drive?

    - by Ben
    I'm trying to fix the floppy drive in my Roland MC-500. The floppy drive inside is a Matsushita DDF3-1 which doesn't seem to be in production anymore. The DDF3-2 is still available, however it is an HD drive. Does anyone know off the top of their heads if there is any issue with simply swapping the two drives? Could the power usage be different on the drives? Since the machine is expecting a 720k DD drive, are there any jumper settings to have the HD drive function as a DD drive?

  • Software raid 0 with six disks performance

    - by user134880
    I have some problems with disk performance. I have 6 x WD 500Gb RE4 disks. Each disk gives 135Mb/sec throughput. All measurements are made with hdparm with options "-tT" (I know that it is just synthetic test, but I need some start point to make measurements). I have controller with Sil3124 x 4 ports PCI Express 1x So... RAID0 on controller with 2 disks gives 200Mb/s - ok, pcie limit. RAID0 on motherboard with 2 disks gives 270Mb/s - niceeee :) RAID0 on contorller with 4 disks gives 200Mb/s - ok, pcie limit. RAID0 on controller with 4 disks + 1 disks on motherboard = 340Mb/s ... :( RAID0 on controller with 4 disks + 2 disks on motherboard = 300Mb/s .... why? Any ideas? Maybe need more cpu power? Now there is Pentium D Dual core 2.8Ghz, 4Gb RAM. It is dedicated box for storage.. no other activity.

  • Strange Phantom Local Disks appearing in my drive list...

    - by Paul
    Win7 Home Prem 32 bit I seem to have several phantom Local Disks mapped to different letters, they are of 0 bytes in size? Strangely they do not show up when i view my drives through windows explorer but if i open an application such as ACDSee Pro or MS Word and then go to open a file i can see all these Local Disks mapped to different letters. This means when i plug in my external hard disk it ends up mapped to letter R instead of its usual G which messes up any programs i have pointing to it by default. How did they get there and more importantly how do i get rid of them please??

  • Windows XP Setup Fails to Recognize USB Floppy after formatting AHCI disk

    - by Strahn
    I am attempting to install Windows XP Professional x64 onto a HP EliteBook 8540w. I have downloaded both the latest Intel Rapid Storage Technology drivers and the Intel Storage Matrix drivers that are listed on HPs website and copied the drivers over to a floppy disk (two separate floppies, one for each version of the drivers.) Booting to my WinXP Pro x64 install CD, I go through the F6 process, load the driver and am able to see my HDD, delete, create and format partitions on it. When I go to continue the install, after checking the disk, the system asks me to enter the disk labeled "Intel Rapid Storage Technology" and press enter to continue. Nothing happens at this point when I press enter. This happens if I use the latest drivers or the older drivers. We have created a slipstreamed install CD using nLite that has the AHCI drivers integrated, which installs fine. However, we have identified a number of issues with the system that I believe are side-effects of using nLite for the slipstreaming and I am attempting to verify that. I have researched this issue and found a few examples of others having the same problem, but no solution. The USB floppy is a Lacie branded floppy, connecting it to a working XP workstation shows it to be the Y-E Data USB floppy drive that is supposedly 100% compatible with XP per MS KB 916196.

  • Apple IIe Software Disks

    - by Mike Grace
    I just got a working Apple IIe but I don't have any system or software disks. I did some searches on Google to look for sources for disks but haven't been able to find many resources that I could actually buy disks from. What are some good places to purchase disks for my Apple IIe? Are there some good groups on the web where others are using and restoring Apple IIes?

  • Existing Instance, Shiny New Disks

    - by merrillaldrich
    Migrating an Instance of SQL Server to New Disks I get to do something pretty entertaining this week – migrate SQL instances on a 2008 cluster from one disk array to another! Zut alors! I am so excited I can hardly contain myself, so let’s get started. (Only a DBA could love this stuff, am I right? I know.) Anyway, here’s one method of many to migrate your data. Assumption : this is a host-based migration, which just means I’m using the Windows file system to push the data from one set of SAN disks...(read more)

  • Removing mdadm array and converting to regular disks while preserving data

    - by Jeffrey Kevin Pry
    I have a 6 disk (2TB each) mdadm RAID 5 volume created in Ubuntu 12.04 Server. However, I'm moving to a different solution and want to "unraid" my disks but keep the data. Only 50% is in use. From what I can surmise I basically have to do this recursively for each physical disk. Fail the disk Format the failed disk Move a portion of files to the new disk. Reshape the array Shrink the logical volume md0 This seems like a very time consuming process. Is there an easier way to do this (automatically perhaps) without buying new disks to temporarily hold the data? I am also aware that during this processing my RAID volume will be degraded and vulnerable the entire time. I am not too concerned about this and will be using battery backup and moving the most important files off first. Thank you for your help!

  • Reconstructing the disk order in RAID 6 with 7 disks

    - by rkotulla
    a little background to this question first: I am running a RAID-6 within a QNAP TS869L external RAID/NAS system. I started with 5 disks of 3 TB each back in the day, and later added another 2 disks of 3TB to the RAID. The QNAP internals handled the growing and re-syncing etc, and everything seemd to be perfectly fine. About 2 weeks ago, I had one of the disks (disk #5, disk #2 has gone bad in the mean time) fail, and somehow (I have no idea why), also disks 1 and 2 got kicked out of the array. I replaced disk #5, but the RAID didn't start working again. After some calls to QNAP technical support, they re-created the array (using mdadm --create --force --assume-clean ...), but the resulting array couldn't find a filesystem, and I was kindly referred to contact a data recovery company that I can't afford. After some digging through old log files, resetting the disk to factory default, etc, I found a few errors that were made during this re-create - I wish I still had some of the original metadata, but unfortunately i don't (I definitely learned that lesson). I'm currently at the point where I know the correct chunk-size (64K), metadata-version (1.0; factory default was 0.9, but from what I read 0.9 doesn't handle disks over 2 TB, mine are 3 TB), and I now find the ext4 filesystem that should be on the disks. Only variable left to determine is the right disk order! I started using the description found in answer #4 of "Recover RAID 5 data after created new array instead of re-using" but am a little confused on what the order should be for a proper RAID-6. RAID-5 is pretty well documented in a number of places, but RAID-6 much less so. Also, does the layout, i.e. distribution of parity and data chunks across the disks, change after the growing of the array from 5 to 7 disks, or does the re-sync re-organize them in such a way a native 7-disk RAID-6 would have been? Thanks some more mdadm output that might be helpful: mdadm version: [~] # mdadm --version mdadm - v2.6.3 - 20th August 2007 mdadm details from one of the disks in the array: [~] # mdadm --examine /dev/sda3 /dev/sda3: Magic : a92b4efc Version : 1.0 Feature Map : 0x0 Array UUID : 1c1614a5:e3be2fbb:4af01271:947fe3aa Name : 0 Creation Time : Tue Jun 10 10:27:58 2014 Raid Level : raid6 Raid Devices : 7 Used Dev Size : 5857395112 (2793.02 GiB 2998.99 GB) Array Size : 29286975360 (13965.12 GiB 14994.93 GB) Used Size : 5857395072 (2793.02 GiB 2998.99 GB) Super Offset : 5857395368 sectors State : clean Device UUID : 7c572d8f:20c12727:7e88c888:c2c357af Update Time : Tue Jun 10 13:01:06 2014 Checksum : d275c82d - correct Events : 7036 Chunk Size : 64K Array Slot : 0 (0, 1, failed, 3, failed, 5, 6) Array State : Uu_u_uu 2 failed mdadm details for the array in the current disk-order (based on my best guess reconstructed from old log-files) [~] # mdadm --detail /dev/md0 /dev/md0: Version : 01.00.03 Creation Time : Tue Jun 10 10:27:58 2014 Raid Level : raid6 Array Size : 14643487680 (13965.12 GiB 14994.93 GB) Used Dev Size : 2928697536 (2793.02 GiB 2998.99 GB) Raid Devices : 7 Total Devices : 5 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Tue Jun 10 13:01:06 2014 State : clean, degraded Active Devices : 5 Working Devices : 5 Failed Devices : 0 Spare Devices : 0 Chunk Size : 64K Name : 0 UUID : 1c1614a5:e3be2fbb:4af01271:947fe3aa Events : 7036 Number Major Minor RaidDevice State 0 8 3 0 active sync /dev/sda3 1 8 19 1 active sync /dev/sdb3 2 0 0 2 removed 3 8 51 3 active sync /dev/sdd3 4 0 0 4 removed 5 8 99 5 active sync /dev/sdg3 6 8 83 6 active sync /dev/sdf3 output from /proc/mdstat (md8, md9, and md13 are internally used RAIDs holding swap, etc; the one I'm after is md0) [~] # more /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] md0 : active raid6 sdf3[6] sdg3[5] sdd3[3] sdb3[1] sda3[0] 14643487680 blocks super 1.0 level 6, 64k chunk, algorithm 2 [7/5] [UU_U_UU] md8 : active raid1 sdg2[2](S) sdf2[3](S) sdd2[4](S) sdc2[5](S) sdb2[6](S) sda2[1] sde2[0] 530048 blocks [2/2] [UU] md13 : active raid1 sdg4[3] sdf4[4] sde4[5] sdd4[6] sdc4[2] sdb4[1] sda4[0] 458880 blocks [8/7] [UUUUUUU_] bitmap: 21/57 pages [84KB], 4KB chunk md9 : active raid1 sdg1[6] sdf1[5] sde1[4] sdd1[3] sdc1[2] sda1[0] sdb1[1] 530048 blocks [8/7] [UUUUUUU_] bitmap: 37/65 pages [148KB], 4KB chunk unused devices: <none>

  • Very slow write access to SSD disks on some Asus P8Z77 motherboards

    - by lenik
    I have Asus P8Z77-V LK motherboard, that ran Mint 13 (based on Ubuntu 12.04) just perfectly, but recently I've tried to install Mint 17 and noticed abysmal write performance. Write speed on SSD disk was about 1.5MB/sec, when it's supposed to be in 150-250MB/sec range. For write testing I've used dd if=/dev/zero of=/dev/sda bs=10M count=10 while booted up from LiveCD. I have also tested the read speed with hdparm -tT /dev/sda and got about 440MB/sec -- that's normal. I can tell, the read performance has not degraded at all and is not an issue here. Since I had a few different SSD disks and few motherboards, I've tested and tested and here are results: Asus P8H77 works fine with Mint13, has very slow write speed starting from Mint14. Asus P8Z77-V LK works with Mint13, has very slow write speed starting from Mint14. Asus P8Z77-V PRO works with Mint13, and works just fine with Mint14, 15, 16 and 17. The only difference between "PRO" version and others is that it has extra SATA controller onboard (in addition to the Z77 chipset SATA controller) providing extra 2 SATA ports. SSD disks work fine with "PRO" version when connected to the native SATA ports as well as to the ports provided by extra SATA controller, so this does not look like a hardware issue. As far as I can tell, there's something changed in the kernel while going from 3.2 to 3.5, that affects the detection of onboard SATA controller for Asus P8*77 motherboards, that screws up the write speed for SSD drives. Could anyone shed some light on how to fix this issue or, possibly, give a pointer to a more suitable place to ask this question?

  • How to use more than 3 virtual disks in Linux using CentOS and XenServer

    - by 010110110101
    I've attached 5 virtual disks to a Virtual Machine in Citrix XenServer. The VM has the xs-tools installed. Initially it said that it couldn't add so many disks. After I installed the xs-tools, it let me add all the disks. But /dev doesn't show all the disks. It shows these: /dev/xvda /dev/xvdb /dev/xvdc /dev/cdrom Perhaps it is bound by the limits of an IDE bus? (3 disks + CD-ROM) If so, how does one change the VM to use SCSI? Edit: According to the documentation: 2.6.3. VM Block Devices In the PV Linux case, block devices are passed through as PV devices. XenServer does not attempt to emulate SCSI or IDE, but instead provides a more suitable interface in the virtual environment in the form of xvd* devices. It is also possible to get an sd* device using the same mechanism, where the PV driver inside the VM takes over the SCSI device namespace. This is not desirable so it is best to use xvd* where possible for PV guests (this is the default for Debian and RHEL). For Windows or other fully virtualized guests, XenServer emulates an IDE bus in the form of an hd* device. When using Windows, installing the Citrix Tools for Virtual Machines installs a special PV driver that works in a similar way to Linux, except in the fully virtualized environment. Still, with 5 virtual disks attached, I don't see the other xvd devices. Edit #2: (attached requested info) Host Machine: XenServer 6.1 Linux version 2.6.32.43-0.4.1.xs1.6.10.777.170770xen (geeko@buildhost) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-51)) #1 SMP Wed Apr 17 05:52:03 EDT 2013 Guest Machine: CentOS release 6.4 (Final) Linux version 2.6.32-358.6.2.el6.x86_64 ([email protected]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Thu May 16 20:59:36 UTC 2013 Output of 'fdisk -l' on Guest Machine: Note, the disk beyond the first 3 attached are not displaying -- there should be 4 100GB disks.

  • Migration of VM from Hyper-V to Hyper-V R2 - Pass through disks

    - by Andrew Gillen
    I am trying to migrate a VM which is using two pass through disks from a legacy Hyper-V Cluster to a new R2 cluster. The migrated VM cannot use the pass through disks though. The guest OS (2008 R2) doesn't seem to like the disk and eventually tries to format the disk instead of mounting it. The migration process I have been using for all my VMs is to export the VM to a new lun, then add that new lun to the new cluster, importing the vm off it in the hyper-v console, then making it highly available. I assumed I could do the same thing and just add the two pass through disks to the new cluster and then attach them inside Hyper-V. Is there a process I need to follow to migrate pass through disks that does not involve setting up new Luns and robocopying the data over?

  • NetApp FAS270 head doesn't see disks

    - by wfaulk
    I have an FAS270C. For months, I've been running it in a split-head manner (that is, with each head serving data totally independently, and without any clustering even being enabled) in order to facilitate moving some data around. I finally got everything situated, moved all the data to one of the heads, and was trying to get clustering set back up. Now when I try to install OnTap onto the "new" head, it cannot see any of the disks in the head shelf. (That is, the shelf into which the heads are inserted.) I've booted into maintenance mode, and it shows me that the 0b adapter, which should be the adapter that that shelf and its disks should be presented on, is in "OFFLINE (physical)" state. If I try to enable it with either "storage enable adapter 0b" or "fcadmin online 0b", it waits for about 30 seconds and then says: [fci.initialization.failed:error]: Initialization failed on Fibre Channel adapter 0b. [fci.adapter.online.failed:error]: Fibre Channel adapter 0b failed to come online. There is currently nothing attached to its external 0b port. I've tried it with and without an SFP plugged into it, and with and without its internal termination switch on. The currently active head can see those disks, and can see that two of them are assigned to the other head. Before I started reconfiguring, the "new" head could see disks on that shelf. They may even be the same disks that OnTap was installed on previously. Does anyone have any idea how to proceed?
