USB

I'm running Xubuntu and it was a challenge just getting Copy.com on there. (I installed the desktop app on both of my computers.) Now that I have it though, I don't really know how to use it.

I know this is kind of more a Copy.com question, but I don't know anything about Copy.com (besides having it--lol) and besides, I like you LQ guys.

So yeah, I installed the desktop app for Copy.com on both of my computers. I know that if I put something in the Copy folder that will be available to both computers.

But how Copy does the backing up I don't know.

When I change a file or folder do I have to plop that into the Copy folder every time or does Copy somehow update the file or folder in the Copy folder automatically? (It doesn't seem to.)

Okay, when I, say, take the Documents folder from one computer and plop it into the Copy folder that's that. Then I take the Documents folder from the other computer and plop that into the Copy folder, then all the files from both folders will be in the Copy folder (and the Copy cloud), right?

Now I just removed a couple of files from a folder and copied and pasted the folder into the Copy folder. But then when I looked at the Copy folder the files I'd deleted were still there. What's the process? How does it work?

I mean, how does this work as a way of backing things up AND organizing things? To me it seems like a decent way of throwing stuff into the Copy folder (and cloud), but how is that different than Google Drive? I mean, that's not really a backup, is it? It's like a flash drive in the cloud.

And when I combined the same folders (with the same titles anyway, but they each had different files within them) from the two computers I'd expected each folder on each computer to have all the same files that were cumulatively on both. Instead, they're the same. And the cumulative is only on the Copy folder.

I like the notion of just throwing the folders and files into the Copy folder. It's much quicker than Google Drive. But the backing up feature eludes me and the syncing feature makes me fearful that I'll lose data or that the files will become hopelessly less organized.

Thanks.

Lots of posts on internet about flash drives ending up read-only in Linux after using on a windows or mac systme. Gather it is a problem with incorrectly ejecting or the ejection being poorly done.

Usually I can go back to the box and re-eject and all is well. This time even GParted and the resident fedora 21 Disk Utility programs did not even see the drive (which Was visible under "files").

Using disk utility on the "offending" machine, it seems there were many files that were truncated (due to some eject issue? Note the ejection was done "according to Hoyle" ); regardless the flash drive was still read-only. Howeverk, re-trying GParted, which now recognized the drive, the drive was unmounted checked. Some repair was necessary. Currently, I can read, write and copy within the drive.

However, the drive itself is still only read-only for all but the owner (which is not even root). I cannot copy any file to the flash drive. Chmod does nothing (no matter if root or other user tries). I suppose I should be satisfied for the access there is, but if anyone has any more suggestions, it would be great.

Thanks in advance for any info/interest

Hi,
I am trying to write to usb flash drive using a C program. I have just created some files in USB device and doing my tasks using fopen,fread and fwrite on those files. I was just wondering what is the standard data rate that can be achieved using fwrite() on a file in usb. Secondly what is better way of transferring data to USB flash drive using C Program? Obviously I am a newbie

I recently bought a WD external hard drive for storing file of several types. Using gparted I made two partitions, one ntfs for windows files and an ext 4 for linux files. Strangely, I have complete access to ntfs partition from linux side of duel boot system, but do not have permission to access ext4 partition. My root password does not work when I use su to gain root access. It works fine on built in hard drive.

I was copying the contents of a flash drive to a folder. In the middle of it I got an error message:

'Error splicing file: input/output error'

and then it said 'do you want to skip or retry?' And the "all" button was there too. Anyway, I skipped. When I checked the folder, all my data seemed to be there.

Do you think it was?

I mean, what are the implications of the error message and of my "skipping" it?

Next up, when I looked at the contents of my flash drive all the folders and files have a lock icon on them. I can open the files but I can't edit them. And no, the lock switch on my flash drive is not pressed.

Any ideas?

Thanks.

Using a Kingston 4GB datatraveler for drive creation
Created using amd64 1.1.0a of the Kali ISO verified from Kali.org
Drive created using Ubuntu 14.04 on a Dell Latitude E5500

dd seems to create the drive with no errors. The drive boots to the error. Hard reboot into Ubuntu to search for solution has led me to a long series of issues that I have been trying to correct.

A possible fix for the failed to load error is to copy the file to the root of the USB drive (/dev/sdb1). Drive is created with a hidden HPFS/ NTFS fs. 0x17. Changed FS to HPFS/NTS (0x07). Drive now mounts, but when attempting to copy onto drive, I get an error that the file system is read only.

I try to correct the issue using nautilus and the properties menu. It does not allow me to change the view only to read/write even though it shows me as the owner.

I think maybe a command line thing would work, or who knows what else. Maybe an fstab entry? I am continuing to search the web, and hope to work this out.

Any help would be appreciated.

I created a persistent USB thumb drive boot with LUKS for drive encryption (250 MB /boot and then 7.5 GB ext3 root). There's no swap partition because this is just to store some private files.

I want to make two or three copies of this thumb drive to store apart in case one gets destroyed/lost.

When I am booted from that thumb drive, can I plug in a same sized drive and just do a

Code:

dd if=/dev/sdb of=/dev/sdc

command to make a copy of itself to another thumb drive without booting to another host OS? This way when I make changes to one (such as to update the OS, apps, or data), I could then just copy the entire thumb drive over to the other two while still booted in the original USB.

Or would I effectively have to shut down, boot to my normal host OS (or other), and then copy the thumb drives when not booted into them.

i have a few score of files (>50) in fasta format. these work fine in linux os
but i have to send these to a collegue who uses windows. and these files don't open properly in notepad or wordpad. executing save as to windows format does the trick

but i don't want to manually convert all of them

is ther a way i can accomplish conversion of multiple files and saving them in a format of my choosing using say terminal

I keep my Music on a USB flash drive. I do not have room on my laptop to store my mp3 library so this is not an option. Whenever, I remove the flash drive (or restart my computer, i think) my music player (rhythmbox currently) forgets where the music is stored. I have to go through reimporting my whole music library which is time consuming and tedious. I imagine that my music player can't find the files because the flash drive gets mapped to a different mount point or something after restarting or removing the drive.

TL;DR
How can I setup my laptop so that my music player can find my music library on a usb flash drive without needing to constantly re-import my library?

Also, I have the same question to syncing to cloud storage. How can I automatically sync flash storage to the cloud?

Hello.
How can I Convert FAT32 to NTFS without format? In windows I can use below command and it work very nice but how about Linux?

convert Drive: /FS:NTFS

Thanks.
