  • Data transfer is extrem slow after partitioning extern usb drive

    - by user125912
    I bought an extern usb 3.0 drive with 500 gb capacity. OS is Windows 7. I use it with an usb 2.0 slot, no prob. Initially I used it without making several partitions and it was fast as hell. Then I had the great idea to make partitions, one for programs, one for data and one for backup. I chose the free EASEUS Partition Master 9.1.1. and ended up with these partitions: F:Apps, primary, NTFS, 100gb H:Data, logic, NTFS, 250gb B:Backup, logic, NTFS, 150gb THE PROBLEM: When I copy files from C: to F: I get a transfer rate of about 100 KB/S ! When I copy files from C: to H: I get a transfer rate of about 4 MB/S ! thats all muuuch to slow, slower then before. What can I do to speed the shit up? Thanks in advance!

  • Logitech USB keyboard driver not found on Windows 7 x64

    - by AngCaruso
    I have a Logitech Internet 350 Keyboard which has been working fine on my Lenovo T400 laptop for well over three years. Just within the past week or so, Windows 7 can no longer find the driver for it. There is no custom driver from Logitech for this device -- it uses the generic Windows USB HID driver. The keyboard works just fine from the BIOS (and Linux which I dual boot this machine), but Windows 7 cannot find or load the driver for it. Any ideas? I smell a Windows update problem, but have no idea how to fix it, and I really am not interested in rolling back updates. New Info: I just tested a generic Dell USB keyboard and it worked just find, with Windows immediately recognizing the device and installing the HID keyboard class driver. So, it seems that Windows has decided not to recognize my specific Logitech keyboard device. I still suspect a Windows update issue, but I would love to hear other suggestions.

  • Copying large file from SD to HDD via USB failing on Ubuntu

    - by Kent Boogaart
    Hi, I'm attempting to copy some large files from my camera (Canon EOS 500D) to my laptop, which is running 64 bit Ubuntu 9.04. I am using USB to connect the two devices. For most files, it is simply a matter of control-C and control-V. I have done this successfully many times with both photos and small movies (eg. 180MB). However, when I attempt to do this with very large files (eg. 3GB), the copy seems to start with a lot of activity both on the camera and laptop, but after 10 minutes or so the camera is automatically unmounted and the copy fails to complete. I have read that this might be due to the device not mounting as a mass storage device, but I cannot see any obvious way for me to change this behavior. Can anyone offer any direction here? I'll get a USB card reader if necessary, but I'd prefer to be able to just plug my camera in. Thanks

  • Windows 7 - all usb devices go to sleep im idle mode

    - by dvdx
    A strange thing happened after a few updates to the system: Intel rapid storage SSD firmware update Intel Ethernet adapter update GPU Intel update When the computer turns off the screen (after 5 min), an unknown time later, all the USB devices stop working. Sound card Mouse Keybord etc. I can't turn them back on, so I can't wake up the screen or do anything except turn the computer off and back on. I checked my power save profile and all is OK there. I changed in the Device Manager, the Allow USB to sleep in all the hubs. How can I fix this??

  • Linux (lsusb) not showing String Descriptors of a USB device

    - by tzippy
    I have an embedded device that when plugged to a linux host, shows up with vid and pid that are not in the usb.ids file (proprietary IDs). However I provide String Descriptors that do show up when plugged into a Windows Host. But not on a Linux Host. lsusb -v shows only iManufacturer 3 iProduct 2 iSerial 1 But on the device side, when processing the setup requests, I see that the Strings are actually requested by the Host. By Windows and also the Linux Host. The USB Device Tree Viewwer under Windows shows this output: iManufacturer : 0x01 Language 0x0409 : "My Manufacturer" iProduct : 0x02 Language 0x0409 : "MyProduct" iSerialNumber : 0x03 Language 0x0409 : "My Serial" I feel that lsusb does not show all of the information. Is there a more informative tool?

  • WD 1TB Passport Essential not working on some USB ports

    - by user143863
    I have a strange situation here. I got a new Toshiba P850/04P laptop, there are 4 USB 3.0 ports, 2 on the right and 2 on the left. When I plug my WD 1TB Passport Essential into the 2 ports on the left, the drive keeps disconnecting and then connecting again, on and off. Sometimes it works well for 1 hour and then disconnects and even shows the "please format your drive" message. What is odd is: this WD 1TB Passport Essential works perfectly on those 2 ports on the right side. It has been working fine on all other PCs and laptops. Another 500 GB WD passport can work with the USB ports on the left (the ones 1TB can not), also all other devices can work with all 4 ports. I am really confused! Does anyone know what the problem could be?

  • How to fix a Corrupted USB

    - by Help
    My USB stick has suddenly stopped working. It's a Busbi 4GB. My USB used to be G:/ but as soon as I plugged it in, I used to get a pop up box showing that it was plugged in. Now, when I plug this in, it shows as I:/ and no pop up box appears. It shows in my computer as I:/ and when I click to open it says I:/ is not accessible the disk structure is corrupted and unreadable. I have tried to change the file name back to G:/ but nothing happened (this was under disk management). On disk management, it shows Volume as I:/ Layout simple Type Basic File system RAW status Healthy (Active,Primary partition) Capacity 3.42GB. I've tried right clicking properties then the tab tools and click error checking (this option will check the volume for errors). When I click "check now" it comes up with the disk check could not be performed because Windows cannot access the disk.

  • Linux (Ubuntu) USB Auth

    - by themicahmachine
    I want to be able to authenticate with PAM using a USB drive with a file on it. I've read about how to do this with a PAM module that reads the specific USB hardware ID of a device, but if the device malfunctions or is lost, there would be no way to authenticate. I would prefer to use the method BitLocker uses, requiring a particular file to be found on the drive in order to authenticate. That way I can keep another drive in a secure location as a backup. Any other suggestions are welcome. I just want to require a higher level of security that just a password.

  • A script so that you don't forget your usb drive on a public computer

    - by Ava Gailliot
    So I have a problem because I'm an idiot. I seem to always leave my usb drives in public computers at school and the like. I unmount them and log off leaving them still in the pc, and of course I then lose my information and my drive which can be costly. Is there a small script somewhere that I can install to my drive that prompts me to take out my usb stick when I log off of a computer? Since this is mostly for use with public computers I can't put anything on my drive that will later need some sort of admin permissions. I guess if all else fails I'll probably put my drive on a lanyard and keep it around my wrist. lol. Does anyone else have this problem?

  • USB 3.0 Not Working

    - by senzen
    I bought an Asus A43E laptop which comes with one USB 3.0 port. In Windows 7 it was working just fine, but after Windows 8 has been installed the USB doesnt work anymore. When I insert any flash drive windows has no reaction. I have been trying to find a driver but I couldnt find one that fits. I know this port works cause I am able to boot windows throw a flash drive. It might be some driver missing. You guys have any idea how can I solve this?

  • PCI function number for SATA AHCI controller

    - by Look Alterno
    I'm debugging a second stage boot loader for a PC with SATA AHCI controller. I'm able to enumerate the PCI bus and find the hard disk. So far, so good. Now, lspci in my notebook (Dell Inspiron 1525) show me: -[0000:00]-+-1f.0 Intel Corporation 82801HEM (ICH8M) LPC Interface Controller +-1f.1 Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) IDE Controller +-1f.2 Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller \-1f.3 Intel Corporation 82801H (ICH8 Family) SMBus Controller My question: Is SATA AHCI Controller always function 2 in any PC? If not, how I found? I don't pretend to be general; booting my notebook will be good enough, without compromise further refinements.

  • Ubuntu 11.10 loads from live usb fine, but boots to black screen from harddrive. Why?

    - by Estel
    A few days ago I had a hard drive failure, which was running Windows XP (32-bit) just fine. The second hard drive in my computer held a few unimportant files, so I formatted it in the Ubuntu setup and installed 11.10 without a hitch. I had been using it for about a week, but decided to install Windows 7 (64-bit) in order to utilize Networking with my home server (running Windows Server 2000). My system is 64-bit based, and thus I had no problems installing other than a basic RAM error that required me to remove my RAM down to a single stick. I played with the settings in Windows 7 for around an hour before I shut down. After reinstalling the RAM, Windows 7 would not boot. In this, I then assumed that something about my system was rejecting Win7 and I reinstalled Ubuntu. However, now Ubuntu (11.10) boots into black screen, and I've already attempted activating the grub menu with the shift key, and following steps listed here: https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen but nothing seems to work. I've reinstalled twice now, with the same result each time. Now, the very odd part about this whole scenario is that the USB I installed from has no problems booting as a live USB. This puzzles me greatly, because the hard drive boots straight to black screen and the live USB loads normally. At this point, my only theory is that the boot sector of the hard disk was somehow corrupted with Win7, and that Ubuntu was unable to completely write through. I used Darik's Boot n Nuke to wipe the drive, but was met with an error, this also puzzles me because the hard disk has no promblems reading or writing. Any suggestions/comments are appreciated. If you have a theory, I will be more than happy to oblige.

  • A Dozen USB Chargers Analyzed; Or: Beware the Knockoffs

    - by Jason Fitzpatrick
    When it comes to buying a USB charger one is just as good as another so you might as well buy the cheapest one, right? This interesting and detailed analysis of name brand, off-brand, and counterfeit chargers will have you rethinking that stance. Ken Shirriff gathered up a dozen USB chargers including official Apple chargers, counterfeit Apple chargers, as well as offerings from Monoprice, Belkin, Motorola, and other companies. After putting them all through a battery of tests he gave them overall rankings based on nine different categories including power stability, power quality, and efficiency. The take away from his research? Quality varied widely between brands but when sticking with big companies like Apple or HP the chargers were all safe. The counterfeit chargers (like the $2 Apple iPad charger knock-off he tested) proved to be outright dangerous–several actually melted or caught fire in the course of the project. Hit up the link below for his detailed analysis including power output readings for the dozen chargers.

  • Putting and configuring grub on an external drive

    - by HisDudeness
    I want to put a bunch of minor emergency operating systems (such as GParted Live, DSL, Puppy Linux and so on) on a partitioned USB pen drive, with a dedicated grub boot loader on it, which I want to start when I select the drive in the BIOS to boot. The problem is: when writing grub boot options I must tell where kernel and initial ram files are located, but the USB drive can have different letters depending on when I did plug it in, if some others external drive were mounted. So, how can I write appropriate options which automatically refer to the drive grub is installed on without having to specify absolute paths, which might change (I mean, like (hd1,msdos1) ot /dev/sdb1)? And, while we are at it, can I have grub working on a device without an operating system on it to which it can refer? I mean, I want to address the command sudo grub-install /dev/sdb from the LMDE system I'm on right now, but I won't have LMDE on my pen drive. Is that a problem? And installing grub on another device, will I keep the grub I have right now on my HDD?

  • How to Create Shortcuts to Programs on USB Drives

    - by Lori Kaufman
    If you work on multiple computers, you probably use a USB drive to take your favorite portable software with you. Portable application suites like PortableApps.com, CodySafe, or Lupo PenSuite, each have a main menu providing access to the programs installed into the suite. However, there may be reasons why you need to create shortcuts to programs on your USB drive. You may be using a program that does not integrate into the suite’s main menu. Or, you may not be using an official portable application suite at all, and just placing portable software in a folder on your USB drive. Maybe you prefer using shortcuts on the root of the USB drive, like a portable desktop. Whatever your reason, you can’t just create a shortcut to an application on the USB drive and place it in the root of the drive. The shortcut will always refer to the full path of the application, including the drive letter. Different computers assign different drive letters to USB flash drives, so you would have to change the drive letter for your shortcuts when it changes. You can assign a static drive letter to the USB drive. However, if you would rather not do that, there is a way to create shortcuts to programs on a USB drive using relative paths. Because Windows does not support relative paths in shortcuts, we will show you how to create a “shortcut” on the root of a USB drive by creating a batch (.bat) file and converting it to an executable (.exe) file.

I also added the last four lines. Anyway, what can I add to this so that I don't have to reconfigure them each time I restart? Currently, I have to open Sound Settings, then under the hardware tab, select Analog Stereo Output, and then unplug my USB speakers and plug them back in. This makes them pop up so that I can see them. Otherwise, it will not show my Z-5 speakers as a device that can be configured.

  • Can I prevent an IDENTIFY PACKET DEVICE command to a specific device at boot?

    - by Brian Spisak
    This is related to a previous question related to installation that is now resolved. I'm opening a new question, because I still need to get my DVD drive working. Problem: Failed boot when my ASUS DRW-24B1/ST DVD drive is attached to my asmedia ASM1061. Symptom: ata8.00: exception Emask 0x52 Sact 0x0 SErr 0xffffffff action 0xe frozen ata8: SError: { blah blah } ata8.00: failed command: IDENTIFY PACKET DEVICE ata8.00: cmd blah blah res blah blah (ATA bus error) ata8.00: status: { DRDY } ata8: hard resetting link Background: The ASM1061 is a PCIe to SATA bridge providing 2 x 6Gb/s ports and is supposed to be fully compliant to SATA specs. I just discovered in the fine print of my ASUS P8Z77-V pro motherboard that "These SATA ports are for data hard drivers only. ATAPI devices are not supported." However, I have already installed Windows 7 using this drive and I can run the Ubuntu 12.04 installer from it as well. The only time I have a problem is during Ubuntu boot when it tries an IDENTIFY PACKET DEVICE which seems to be an ATAPI command. I can't simply switch this device to another SATA port because they are already allocated to other devices. (My chipset's 2 x 6Gb/s are connected to my boot SSD and a fast HDD while the 4 x 3Gb/s ports are running a RAID 5 array.) If this can't be fixed or worked around, I suppose I'll have to go buy SATA add-in card. Blech. Thoughts: If indeed this is a device specific issue (that it doesn't support ATAPI discovery) then I can't expect - is it udev? - to work with it. But, it seems that Windows and even the Ubuntu installer work just fine. So why does udev have a problem? At the end of the day, it would be nice to have the DVD working under Ubuntu, but I can live without it. But, as this is a dual-boot machine, I can't physically disconnect it because I want it to work with Windows. (And physically disconnecting it every time I want to boot Ubuntu is NOT an option. ;-) Questions: Should this be considered a bug? My feelings are that if it works with other OS that it should probably work with Ubuntu as well. How can I work around this problem? I have a limited knowledge of linux internals, but it seems I should be able to somehow tell udev (or whatever is doing the discovery) to ignore that device. Is there a way?

  • Hard Drive problem: is it the SATA controller or the HDD itself?

    - by Drooling_Sheep
    I have a Samsung 1.5TB hard drive hooked up to an ECS H55H-I mini-ITX motherboard. I have XBMC 10 (modified Ubuntu 10.04) installed for use as an HTPC. The hard drive encounters occasional errors during normal use which cause it to be remounted read-only. I have updated the BIOS on the motherboard, changed the SATA cable and moved it to different ports on the motherboard, installed and re-installed the OS (including different versions of XBMC and generic ubuntu), all to no avail. I recently ran tests both with badblocks -sv and smartctl -t long. Both reported no errors. This makes me think the motherboard or SATA controller is probably the issue. Does anyone know of any further tests I can do to help narrow this down? The processor is a Core i3. I forget the model number but it's one of the 32nm ones with on-package graphics. There's no discrete video card or optical drive. The power supply is a 150W Rosewill (pretty sure) that came with the case.

  • How can a single disk in a hardware SATA RAID-10 array bring the entire array to a screeching halt?

    - by Stu Thompson
    Prelude: I'm a code-monkey that's increasingly taken on SysAdmin duties for my small company. My code is our product, and increasingly we provide the same app as SaaS. About 18 months ago I moved our servers from a premium hosting centric vendor to a barebones rack pusher in a tier IV data center. (Literally across the street.) This ment doing much more ourselves--things like networking, storage and monitoring. As part the big move, to replace our leased direct attached storage from the hosting company, I built a 9TB two-node NAS based on SuperMicro chassises, 3ware RAID cards, Ubuntu 10.04, two dozen SATA disks, DRBD and . It's all lovingly documented in three blog posts: Building up & testing a new 9TB SATA RAID10 NFSv4 NAS: Part I, Part II and Part III. We also setup a Cacit monitoring system. Recently we've been adding more and more data points, like SMART values. I could not have done all this without the awesome boffins at ServerFault. It's been a fun and educational experience. My boss is happy (we saved bucket loads of $$$), our customers are happy (storage costs are down), I'm happy (fun, fun, fun). Until yesterday. Outage & Recovery: Some time after lunch we started getting reports of sluggish performance from our application, an on-demand streaming media CMS. About the same time our Cacti monitoring system sent a blizzard of emails. One of the more telling alerts was a graph of iostat await. Performance became so degraded that Pingdom began sending "server down" notifications. The overall load was moderate, there was not traffic spike. After logging onto the application servers, NFS clients of the NAS, I confirmed that just about everything was experiencing highly intermittent and insanely long IO wait times. And once I hopped onto the primary NAS node itself, the same delays were evident when trying to navigate the problem array's file system. Time to fail over, that went well. Within 20 minuts everything was confirmed to be back up and running perfectly. Post-Mortem: After any and all system failures I perform a post-mortem to determine the cause of the failure. First thing I did was ssh back into the box and start reviewing logs. It was offline, completely. Time for a trip to the data center. Hardware reset, backup an and running. In /var/syslog I found this scary looking entry: Nov 15 06:49:44 umbilo smartd[2827]: Device: /dev/twa0 [3ware_disk_00], 6 Currently unreadable (pending) sectors Nov 15 06:49:44 umbilo smartd[2827]: Device: /dev/twa0 [3ware_disk_07], SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 171 to 170 Nov 15 06:49:45 umbilo smartd[2827]: Device: /dev/twa0 [3ware_disk_10], 16 Currently unreadable (pending) sectors Nov 15 06:49:45 umbilo smartd[2827]: Device: /dev/twa0 [3ware_disk_10], 4 Offline uncorrectable sectors Nov 15 06:49:45 umbilo smartd[2827]: Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error Nov 15 06:49:45 umbilo smartd[2827]: # 1 Short offline Completed: read failure 90% 6576 3421766910 Nov 15 06:49:45 umbilo smartd[2827]: # 2 Short offline Completed: read failure 90% 6087 3421766910 Nov 15 06:49:45 umbilo smartd[2827]: # 3 Short offline Completed: read failure 10% 5901 656821791 Nov 15 06:49:45 umbilo smartd[2827]: # 4 Short offline Completed: read failure 90% 5818 651637856 Nov 15 06:49:45 umbilo smartd[2827]: So I went to check the Cacti graphs for the disks in the array. Here we see that, yes, disk 7 is slipping away just like syslog says it is. But we also see that disk 8's SMART Read Erros are fluctuating. There are no messages about disk 8 in syslog. More interesting is that the fluctuating values for disk 8 directly correlate to the high IO wait times! My interpretation is that: Disk 8 is experiencing an odd hardware fault that results in intermittent long operation times. Somehow this fault condition on the disk is locking up the entire array Maybe there is a more accurate or correct description, but the net result has been that the one disk is impacting the performance of the whole array. The Question(s) How can a single disk in a hardware SATA RAID-10 array bring the entire array to a screeching halt? Am I being naïve to think that the RAID card should have dealt with this? How can I prevent a single misbehaving disk from impacting the entire array? Am I missing something?

  • Create a Persistent Bootable Ubuntu USB Flash Drive

    - by Trevor Bekolay
    Don’t feel like reinstalling an antivirus program every time you boot up your Ubuntu flash drive? We’ll show you how to create a bootable Ubuntu flash drive that will remember your settings, installed programs, and more! Previously, we showed you how to create a bootable Ubuntu flash drive that would reset to its initial state every time you booted it up. This is great if you’re worried about messing something up, and want to start fresh every time you start tinkering with Ubuntu. However, if you’re using the Ubuntu flash drive to diagnose and solve problems with your PC, you might find that a lot of problems require guess-and-test cycles. It would be great if the settings you change in Ubuntu and the programs you install stay installed the next time you boot it up. Fortunately, Universal USB Installer, a great little program from Pen Drive Linux, can do just that! Note: You will need a USB drive at least 2 GB large. Make sure you back up any files on the flash drive because this process will format the drive, removing any files currently on it. Once Ubuntu has been installed on the flash drive, you can move those files back if there is enough space. Put Ubuntu on your flash drive Universal-USB-Installer.exe does not need to be installed, so just double click on it to run it wherever you downloaded it. Click Yes if you get a UAC prompt, and you will be greeted with this window. Click I Agree. In the drop-down box on the next screen, select Ubuntu 9.10 Desktop i386. Don’t worry if you normally use 64-bit operating systems – the 32-bit version of Ubuntu 9.10 will still work fine. Some useful tools do not have 64-bit versions, so unless you’re planning on switching to Ubuntu permanently, the 32-bit version will work best. If you don’t have a copy of the Ubuntu 9.10 CD downloaded, then click on the checkbox to Download the ISO. You’ll be prompted to launch a web browser; click Yes. The download should start immediately. When it’s finished, return the the Universal USB Installer and click on Browse to navigate to the ISO file you just downloaded. Click OK and the text field will be populated with the path to the ISO file. Select the drive letter that corresponds to the flash drive that you would like to use from the dropdown box. If you’ve backed up the files on this drive, we recommend checking the box to format the drive. Finally, you have to choose how much space you would like to set aside for the settings and programs that will be stored on the flash drive. Considering that Ubuntu itself only takes up around 700 MB, 1 GB should be plenty, but we’re choosing 2 GB in this example because we have lots of space on this USB drive. Click on the Create button and then make yourself a sandwich – it will take some time to install no matter how fast your PC is. Eventually it will finish. Click Close. Now you have a flash drive that will boot into a fully capable Ubuntu installation, and any changes you make will persist the next time you boot it up! Boot into Ubuntu If you’re not sure how to set your computer to boot using the USB drive, then check out the How to Boot Into Ubuntu section of our previous article on creating bootable USB drives, or refer to your motherboard’s manual. Once your computer is set to boot using the USB drive, you’ll be greeted with splash screen with some options. Press Enter to boot into Ubuntu. The first time you do this, it may take some time to boot up. Fortunately, we’ve found that the process speeds up on subsequent boots. You’ll be greeted with the Ubuntu desktop. Now, if you change settings like the desktop resolution, or install a program, those changes will be permanently stored on the USB drive! We installed avast! Antivirus, and on the next boot, found that it was still in the Accessories menu where we left it. Conclusion We think that a bootable Ubuntu USB flash drive is a great tool to have around in case your PC has problems booting otherwise. By having the changes you make persist, you can customize your Ubuntu installation to be the ultimate computer repair toolkit!

  • "Could not claim interface on camera: -6" when trying to connect usb camera (Kinect)

    - by rzetterberg
    I have installed the freenect library from openkinect.org. With that library there is a demo application which you can run from the terminal to test out the Kinect. However when I run this command I get the following output: richard@behemoth:~$ sudo freenect-glview Kinect camera test Number of devices found: 1 Could not claim interface on camera: -6 Could not open device This particular error is thrown by the library libusb by the function libusb_claim_interface and the error -6 corresponds to the LIBUSB_ERROR_BUSY. So my guess is that it has something to do with mounting the usb, rather than specifically the freenect library or the Kinect itself. So my question is how can I find out what resource is using this interface and how can I free it so that I can access it? Edit: What I have tried so far (just to be sure): Rebooted Plugged-out, plugged-in Tried different usb ports Restarted udev Additional information that might be useful: /etc/fstab: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda1 during installation UUID=1c73f217-ac8d-451b-8390-7a680628a856 / ext4 errors=remount-ro 0 1 # swap was on /dev/sda5 during installation UUID=bb49bd29-07ec-45a0-bbab-46fb8362b06b none swap sw 0 0 sudo uname -r: Linux behemoth 3.0.0-14-generic-pae #23-Ubuntu SMP Mon Nov 21 22:07:10 UTC 2011 i686 i686 i386 GNU/Linux cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=11.10 DISTRIB_CODENAME=oneiric DISTRIB_DESCRIPTION="Ubuntu 11.10"

  • Windows 7 cannot view FAT32 formatted bootable usb drive

    - by NaimK
    I'm having some issue where when I run bootsect with a command line of "bootsect.exe /nt52 : /force /mbr", then Windows 7 (the comp I'm running bootsect on) can no longer view the contents of the usb drive. Explorer tries to look at it, and then fails, and I can't even correctly eject the drive, when I try, it does nothing until I yank it out, and then I get some errors. Bootsect reports success on writing the volume and the drive data to make it bootable, but it doesn't boot after copying on the necessary files (files from a created ISO, it works when it is created on XP). But this may be that I'm not following the same instructions as when building it on XP since some of the command don't seem to always work correctly. The drive is formatted to FAT32 (necessary I think, cause I'm installing a custom version of Win XP embedded). Any ideas? Or perhaps a good or automated way to load a usb with a custom version of win xp and make it bootable from Win 7? I am having some issues, for instance, "ufdprep.exe" rarely works when I'm running it from Windows 7, I don't know why.
