for solution how to find physical position/block of specified file on FAT32 partition. I have damaged hdd (I can mount partition and I see files) and im using gddrescue to make 1:1 copy, but i need only specified file. So I would like use gddrescue with -i pos switch, but I dont know how to get that position for specified file.
Code:
-i pos
--input-position=pos
[code]...
How can I retrieve the block number(s) of a certain file in a file system (the blocks the file is using on the harddisc)?
I'm using the gentoo linux based SystemRescueCD, so I got plenty of tools installed which might get that information for me.
I'd like to improve my computer's performance by storing files' system location (e.g.: /home/user/speech.odt) and HD position (head, sector, etc) and do the computer use that info from ram memory.I have a directory with several files and when I cd and ls it, it takes a while to the computer answer me. Plus, it would return immidiate find results.
View 2 Replies View RelatedI have a Windows 7 partition, a fat32 partition that I use for moving data between Windows and Linux, and an Ubuntu partition. On the Ubuntu partition, I can right click on a text file and the top of the menu says "open with 'gedit'." On the fat32 partition, the same action says just "open," and the "open with" submenu doesn't include gedit.
If I right-click and choose properties on the same file, the "open with" tab shows gedit as the default file association. So that's weird... anyone else seen anything like this?
I love how totem handles using mousewheel up/down to change position in a media file. VLC doesn't do it the same way by default so I've been trying to find a way to replicate that feature. I found the appropriate actions and assigned mousewheel up/down for both the hotkey and global options. Unfortunately when I try to seek it only works if I mouse over the position bar or lower half of the application. If I am moused over the actual video the hotkeys don't work. In fullscreen the hotkeys don't work at all and I can only seek by holding my mouse over the position bar.

View 1 Replies View RelatedI have just recovered my desktop Ubuntu system, thanks to SuperGrub, and Larryfroot, who pointed me to it. It had crashed due to an incomplete install to a pen drive, but prior to this I had made some changes to my partition layout, and now if such moves could cause the problems I'm having now.I wanted to be able to access my pictures, music, and projects while testing different Linux distros from CD or pen drive (DreamLinux looks much like the Mac interface, which I like, it's rated for speed, gotta try), but I've not been able to do that from any which I've tried yet. I learned somewhere that replacing the unused bulk of the OS partition with a big FAT32, and moving your files to that drive should make them accessible to most systems. I just viewed my files from the DreamLinux distro CD, so it seems to be working. I knew the action on this type of partition would be slower, and it really is when I move files to it, so is there a better way to get what I want than this?I have since had the following annoyances from Ubuntu's Nautilus file browser, and am wondering if the drive changes had anything to do with the following:
1. I am getting error messages when I try to move files to this drive through the Nautilus GUI file browser, but then these errors are wierdly negated when the file transfer is performed anyway. Well, I should be happy that it does what I ask, but where are these false error messages coming from?
2. It gets even more strange - when viewing files on Fat32 through Nautilus, in my Ubuntu hard drive partition, the file window has a banner which states "These files are on a Picture CD". Huh??? I know where I moved my files to, and they are not on CD! What is a "Picture CD" anyway?
Can anyone find a logical explanation for these weird messages, or does it look as much to you like corruption damage?
What is the vim command I have to use when I want to perform a text substitution not on the current line or on the whole document or on lines from number x to number y but just from the current cursor position down to the end (or up to the beginning) of the document?

View 9 Replies View Relatedi needed to change my external hard drive's file system from ext3 to fat32, to use it in windows, which i did the simple way: i shrunk the ext3 partition, made a fat32 partition, copied the files over, removed the ext3 and made the fat32 bigger. unfortunately, while gparted was making the partition larger, my computer shut down. i lost all my files and the partition messed up immediately. i made a new fat32 partition, after deleting the old one, but noticed that gparted was showing 100 gigs already in use (???). so now i have a 300 gb hard drive with only 200 gb i can use; i ran df to make sure gparted wasn't messing up, but indeed it shows the partition as being only 200 gigs in size. i haven't tried making any other kind of partition yet, such as ext3, for fear of losing my files again, and because it wouldn't be permanent anyway, because i need those files in windows and stupid microsoft won't make their OS ext3 compatible.

algorithm:breada
input: file system block number for immediate read
file system block number for asynchronous read
output:buffer containing data for immediate read {
if(first block not in cache) {
get buffer for first block
if(buffer data not valid)
initiate disk read }
if(second block not in cache) {
get buffer for second block)
if(buffer data valid) //line 1
release buffer else
initiate disk read //line 2 }
if(first block was originally in cache) //line 3 {
read first block
return buffer }
sleep (event first buffer contains valid data)
return buffer }
Here is an algorithm for block read algorithm. I have problem in
line 1: If buffer data is valid why is it releasing the buffer?
line 2: If buffer data valid why is it initiating disk read. It should have read directly from buffer?
line 3: It should be the first condition as if it is there in cache then it should return it without delay?
I'm looking for a write one, read many file synchronization, file system or similar technique. In fact I want a to imitate a zfs_send/zfs_receive similar behaviour on Linux. My requirements are pure local (or in terms of distributed file systems: rack-aware) file handling with remote synchronization. Some random features/requirements I want to achieve are (I use the terms file and "file system" here interchangeable, as I don't care wheter I have to synchronize file based or use full file system supporting that):
Access on files from a specific host is pure local, i.e. the node has a full copy of a file, no parts are distributed. Read and write access is local, the remote side gets synchronized with write changes only Write changes on the remote side are non-blocking and asynchronous No need for concurrent file access, concurrent, distributed locking and so on Every file is changed by a single node only, other nodes have read access The file "owner", thus the node allowed to write files must be changeable Similar techniques (some as technology concept, not usable for me) exist, among those DRBD, MySQL Replication or even pure rsync.
I don't care whether I'm referring to a pure local solution (i.e. between two block devices) or a client/server mode. DRBD won't fit because its a peer to peer solution, I need to synchronize a lot of clients with a central storage through that way where DRBD just mirrors from peer to peer among two nodes and doesn't allow another node to take over the role of the primary node (i.e. node A is master, storage B secondary, I want to change to a thrid node C which becomes master and receives hence a full update from storage B.
Just as a guess, I'd make a local LVM volume on every node where write access happens. In the same time there exists a iSCSI target with multipath to a remote hosts which is shared with every node, again providing a clustered LVM. So I'd need to synchronize a local LVM volume with a remote LVM image. The question is just by which technique I could achieve that (i.e. as RAID 0, where every read and write goes to one node only and doesn't wait the other node to succeed). I could achieve this with rsync by a cyclic push to the remote host, but the problem is, that rsync isn't block based thus I'd need to synchronize every time the whole file, not only changes.
