  • Does the FAT filesystem have a signature?

    - by DxCK
    Given the following BPB: The "MSWIN4.1" string is just the "OEM ID" field, and by Microsoft documentation it should not be used to identify FAT volumes. The "FAT32 " string is the BS_FilSysType field, and by Microsoft documentation it should not be used to identify FAT volumes either. So how do i identify that the volume is formatted to FAT? Is there any reliable signature I can relay on?

  • Check for type of file system in an MSI package

    - by Hugo
    In my MSI package I need to set user rights to a directory using cacls.exe. It works fine in an NTFS environment but fails when run on a Fat32 file system. Is there a method to determine the type of file system of the drive the software is installed to? I'm using WiX 3 to create my MSI package but any hint pointing to the MSI database would help as well. Many thanks in advance.

  • How do I debug this FS error on a flash device?

    - by abc
    I have console access to an embedded linux device. This device has flash memory part of which is partitioned as a FAT filesystem. Its running linux-2.6.31. However I am seeing these errors on the console these days and the FAT file system becomes read only. 111109:154925 FAT: Filesystem error (dev loop0) 111109:154925 fat_get_cluster: invalid cluster chain (i_pos 0) 111109:154925 FAT: Filesystem error (dev loop0) 111109:154925 fat_get_cluster: invalid cluster chain (i_pos 0) I cannot understand why this happened? What is the root cause? And what is the fix? I would appreciate answers that can point me how to investigate the possible root cause of this issue on the device.

  • Best undelete tool for NTFS/FAT?

    - by Vinko Vrsalovic
    What is the best tool for file undeletion in your experience? Google shows a gazillion of them, but I'd like to hear about good (or bad) experiences with any of those. Objective: Restoring 500.000 audio (WAV PCM) files. Doesn't matter if it's commercial, free or open source, it matters how quick and reliable it is.

  • Why can't windows see mmcblk0p3? [closed]

    - by jacknad
    The partition is created on the embedded linux target like this # n - new # p - partition # 3 - partition 3 # 66 - starting cylinder # <blank> - maximum size for the ending cylinder # t - set file system type # 3 - partition 3 # c - set to windows vfat # w - write partition table and exit echo -e "n\np\n3\n66\n\nt\n3\nc\nw" | fdisk /dev/mmcblk0 The file system is then formatted on the embedded linux target as MS-DOS like this # -n volume-name # -F FAT-size mkfs.vfat -n DB -F 32 /dev/mmcblk0p3 A linux host can mount and access files in mmcblk0p3 without issue. Why can't windows? Edit: Although the default number of FATS is 2 I tried adding -f 2 [number-of-FATs] since this is actually being done by busybox on an embedded platform but this didn't help. I understand the Linux MS-DOS file system does not support more than 2 FATs but there are only 2 on this target (the boot is also FAT which is visible), along with and EXT3 (on p2) for the root file system.

  • Autounmounting USB keys with FAT filesystem on Linux (RHEL5)

    - by niXar
    For security reasons, I have two workstations i front of me, and I can only transfer data between them through a USB key. As you can imagine, it can get quickly tiresome, but the most annoying is having to unmount the things before removing them. Not umounting them results in missing files most of the time, even if I remove them a while after having last written to them. Now, since they're only used for transferring smallish files, and each are basically written once and read once, I don't need the fancy pansy caching infrastructure that makes clean unmounting a necessary step. And since the data is always a copy of something I have at hand, I don't care if the filesystem croaks from time to time. But anyway the system doesn't need to force that on me, it could simply make sure everything is committed with a second, and works synchronously. Then when I remove the key, nothing is lost. Is there a way to do this? I would appreciate any other tips on handling this situation. Edit: it appears the situation has changed between RHEL5 and Fedora up to F11 on one hand, and F12 on the other. The latter use DeviceKit-disk, and I haven't quite figured out how to do this. The method provided below in gconf does not work anymore.

    FUSE filesystem list show some FuseFat and FatFuse. One is 404 not found, others is old, not buildable and probably depends on glib. Now I'm using mountlo for the task (mounting USB drives in generic way without root access or suid things (except of fusermount itself), but it looks too big for such task. Is there good vfat FUSE driver?

Now I'm using mountlo for the task (mounting USB drives in generic way without root access or suid things (except of fusermount itself)), but it looks too big for such task. Using FUSE to mount external storage devices is good both for security and for flexibility reason: the kernel sees only block reads and writes while actual code that deals with filesystem details runs with user privileges, allowing user to use custom filesystems and preventing from kernel filesystem exploits. Is there good vfat FUSE driver?

  • Setting Mercurial's execute bit on Windows

    - by Joe
    I work on a Mercurial repository that is checked out onto an Unix filesystem such as ext3 on some machines, and FAT32 on others. In Subversion, I can set the svn:executable property to control whether a file should be marked executable when checked out on a platform that supports such a bit. I can do this regardless of the platform I'm running SVN on or the filesystem containing my working copy. In Mercurial, I can chmod +x to get the same effect if the clone is on a Unix filesystem. But how can I set (or remove) the executable bit on a file on a FAT filesystem?

  • Copy File Contiguously to Disk from OSX/Unix/Linux to FAT32 FS?

    - by alharaka
    So the Sysinternals guys have that cool contig.exe utility that allows me ensure a file is contiguous. I need to copy overs ISO files to a FAT32 USB flash key. Grub4DOS requires the files be continuous, but I do not have Windows access at the moment. Is there a way to copy a file so it is contiguous on the target drive, or a tool like the aforementioned that will make an existing file contiguous. Again, I need it on FAT32, and there lies the rub.

  • Is there a limit for the number of files in a directory on an SD card?

    - by jamesh
    I have a project written for Android devices. It generates a large number of files, each day. These are all text files and images. The app uses a database to reference these files. The app is supposed to clear up these files after a little use (perhaps after a few days), but this process may or may not be working. This is not the subject of this question. Due to a historic accident, the organization of the files are somewhat naive: everything is in the same directory; a .hidden directory which contains a zero byte .nomedia file to prevent the MediaScanner indexing it. Today, I am seeing an error reported: java.io.IOException: Cannot create: /sdcard/.hidden/file-4200.html at java.io.File.createNewFile(File.java:1263) Regarding the sdcard, I see it has plenty of storage left, but counting $ cd /Volumes/NO_NAME/.hidden $ ls | wc -w 9058 Deleting a number of files seems to have allowed the file creation for today to proceed. Regrettably, I did not try touching a new file to try and reproduce the error on a commandline; I also deleted several hundred files rather than a handful. However, my question is: are there hard limits on filesize or number of files in a directory? am I even on the right track here? Nota Bene: The SD card is as-is - i.e. I haven't formatted it, so I would guess it would be a FAT-* format. The FAT-32 format has hard limits of filesize of 2GB (well above the filesizes I am dealing with) and a limit of number of files in the root directory. I am definitely not writing files in the root directory.

  • What is a good FAT file system for ARM7-TDMI

    - by Seidleroni
    I'm using the ARM7TDMI-S (NXP processor) and I need a file system capable of reading/writing to an SD card. There are so many available, what have people used and been happy with? One that requires the least amount of setup is best - so the less I have to do to get it started (i.e. write device drivers to NXP's hardware) the better.

  • i have xp partitioned and formatted fat32 it says it needs to be bootable to install ubuntu how do i do that? [duplicate]

    - by Rob Bailey
    This question already has an answer here: How do I install Ubuntu? 4 answers I have partitioned the hard drive and formatted it fat 32 as it is only 16gig. I have just read that I should not partition the hard drive so I have deleted the partition, I noticed that if i re-partition it my options would be NTFS, Fat32 or exfat. I tried to install ubuntu 12.10 but it flashed up something along the lines of the partition is not bootable and it must be for ubuntu to install. I know my copy works as a friend installed it over his copy of windows and it works perfect, I have ubuntu on my flashdrive, I want to run it along side xp.

  • Samba issue with sharing directories on NTFS/FAT32 (Mounted Drives) ???

    - by Microkernel
    Hi guys, I have some strange problems with Samba server. I am using samba Version 3.5.4 on Ubuntu 10.10. I have two windows-xp machines, one on VirtualBox on Ubuntu and another office laptop. Windows machine on VBox has no issues in accessing the shared folders, but the laptop is not able to access all the shared content. The issue faced on laptop is = Shared folders on Ext3 drives have no issues in accessing, but the contents shared on NTFS and FAT32 drives (mounted ones) are not accessible. When I try to open the shared folder, it asks for user name and password, but doesn't accept when I provide it. (even if I provide admin login details!!!). I changed workgroup value to the domain_name in office laptop, but still the problem persists... Here is the smdb.conf I am using... [global] workgroup = XXX.XXX.ORG server string = %h server (Samba, Ubuntu) map to guest = Bad User obey pam restrictions = Yes pam password change = Yes passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . unix password sync = Yes syslog = 0 log file = /var/log/samba/log.%m max log size = 1000 dns proxy = No usershare allow guests = Yes panic action = /usr/share/samba/panic-action %d guest ok = Yes [homes] comment = Home Directories [printers] comment = All Printers path = /var/spool/samba read only = No create mask = 0700 printable = Yes browseable = No [print$] comment = Samba server's CD-ROM path = /cdrom force user = nobody force group = nobody locking = No Workgroup Was defined as "HOMENET" before, changed it to domain name on the office laptop thinking it was the problem, but for no avail Thanks in advance Regards, Microkernel

  • I recently converted my ex HDD from FAT32 to NTFS. now my pc doesn't find or pick up my NTFS HDD

    - by Jason Haniball
    I recently converted my external hard drive from FAT32 to NTFS using the Command Prompt. Everything was working fine, I copied a 7GB file to it and everything worked. The next day I switched on my PC, I couldn't and still can't find my external 1.5TB hard drive by my computer. I have about 500 to 800 GB of data on it that I really don't want to lose. Its a Iomega Seagate Freeagent HDD. Has no switch, it switched on automatically, don't know if that helps.

  • Some info about SD card patitions after the use of the dd statment and some oiters doubts?

    - by AndreaNobili
    I am not very experienced using Linux and I have the following situation that cause me some doubts. I have wrote RaspBian (the RaspBerry linux distribution) on an SD card using Ubuntu dd statment: sudo dd if=2014-01-07-wheezy-raspbian.img of=/dev/sdb bs=1024 So if now I perform the fdisk -l statment I obtain that I have 2 partitions related to my SD card, that are the followins: Dispositivo Boot Start End Blocks Id System /dev/sdb1 8192 122879 57344 c W95 FAT32 (LBA) /dev/sdb2 122880 5785599 2831360 83 Linux And now the first doubt: the dd statment create on the SD card two partitions: 1) /dev/sdb1 that is a litle FAT32 partition (what it means (LBA)?) 2) /dev/sdb2 that is a larger Linux ext3 partition Ok...the doubt is: why it also create to me a FAT32 partition and not only a Linux ext3 partition? Ok...if I go into my computer resource I can see a device (related to my SD card) into the devices list that contains some RaspBian file, following a screenshot: And if I see the property of this device I obtain this: So, looking at the previous screenshot it seems to me that this is the small FAT32 partition, and now I have the followings doubts: If it is the smallest FAT32 partition, what contains? The RaspBian boot or what? Why, in the devices list, I have only the FAT32 partition and not also the Linux one (/dev/sdb2), to see it have I to mount it? how? Tnx
