Comparing SSD And Compact Flash Memories

Hello, I have a system that uses a compact flash with a windows os and some other files on it, also somewhere is some sort of encrypted licensing information. I have several of these machines and can use the cf from the others just fine in this machine. But when I take one of those cards and try to copy it with dd, somehow the machine can tell the difference. It's nothing illegal, it's just too old to buy the replacement. Someone has told me they copied successfully in linux with the dd command, but mine aren't working. I also can't tell the brand or type of cf since all the labels have been removed. All i know is that it's a 256mb card. So is there any other options besides dd, or is there a deeper level of dd that i can use to copy this info. I'm using something like:

sudo dd if=/dev/sde of=/home/folder/cfcard

then to copy from my hard drive to the blank cf:

sudo dd if=/home/folder/cfcard of=/dev/sde

I'm using a usb cf reader, and when i have my finished cf everything looks good. Even the machine can read it, it just gives me an error that the cf card isn't a licensed or corrupted.

I have a machine with two drives a Compact Flash card (CF) and a Solid State Drive (SSD). Recently I have been experiencing failures of both the SSD and the CF.

When I sent these back to the manufacturer for analysis, they reported that the SSDs and CDs are healthy - but that it appears that the partition table has become corrupt.

Using a Kickstart I created my Linux machine with the partitions split over the CF (to hold the operating system) and the SSD (to hold my data):
/ on the CF
/boot on the CD
/usr on the CF
/home on the SSD
Would Unix have an issue with using the CF to boot and run the operating system and using the SSD to store files?
Has anyone experienced any issues of this kind?

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?

Firefox is blocking the Flash plugin installed on computer because it says it is out of date

I currently have this plugin:

Shockwave Flash

Path: /usr/lib/flashplugin-installer/libflashplayer.so
Version: 11.2.202.440
State: Enabled (STATE_VULNERABLE_UPDATE_AVAILABLE)
Shockwave Flash 11.2 r202

MIME Type Description Suffixes

What shall I do???

(Note: Before I restarted my computer, there was an Update Information tab open and it read "Restart Nautilus Required", and when I would click on the Restart Nautilus button, nothing would happen. ...I restarted my computer and the tab has not appeared...)

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

Booted my computer with 2 USB flash drives inserted. One of the drives turned out to be an MS-DOS boot drive. The PC booted in DOS and wiped out the partition table of the other flash drive with my data on it. This second (64Gb) drive had a single 64Gb type 83 (Linux) primary partition (ext4 file system).

Is there a way to recover the data that's on the second stick?

I've been told that all I have to do is repartition it exactly as it was and my data will be there. But I'd like to have advice from the pros here before I start messing with it.

For the time being, I dd-ed the entire stick, as is, onto a blank partition of my hard disk (dd if=/dev/sdb of=/dev/sda14). The process completed without errors but /dev/sda14 is unmountable for the moment.

Thanks for any help.

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.

(BTW I'm running Xubuntu 15.04)

I'm starting to understand Luckybackup. And gold_finger said:

Assuming your Xubuntu filesystem is Ext4, example of doing initial backup would be something like this:

* Spare USB with large partition formatted as Ext4 and labeled "BACKUPS"
I know the EXT4 is more friendly to Linux but all my flash drives are FAT32 (and I'll be backing up to those flash drives) and I'd really like to keep them that way (because sometimes I do plug them into Windows machines--and I know FAT32 works with both Windows and Linux). So is there any reason I would have to use Ext4 and not FAT32 in backing up stuff in LuckyBackup?

I confess to great ignorance about the difference between the EXT and FAT formats. Like if I do format a flash drive to EXT 4 and want to plug the flash drive into a Windows computer it just doesn't work? Like, what's the advantage to using EXT4 then if FAT 32 works with Linux and Windows? What are the disadvantages to using EXT4?

Thanks.

Hi guys,

I'm new to this forum and linux too.
I thought of installing a lightweight distro of linux and did some research on the net where I found people recommending Puppy Linux. Plus it is (theoretically speaking) possible to run it from a USB (flash) drive which I decided to try out but it seems like it's not that simple a task as a lot of people (all over the internet) say it is.

What I tried so far is this: installing it into a thumb drive using unetbootin follwing a youtube tutorial (which basically showed how to download an iso of puppy, use unetbootin to make the thumbdrive bootable and install puppy on it). It didn't work. The USB wasn't recognized as a bootable device. I know for sure it can be booted from it since I tried ubuntu from the same USB and the same Laptop (which is able to boot from USB).

I thought that something with the Flash Drive not OK so I tried to use a windows installer to install puppy like other windows programms but this didn't work either. This time Puppy was recognized because there was an option to boot either Puppy or Windows 7 but when I chose to boot from Puppy nothing happens just a screen flash, some letters in the top left corner saying something like NTSC or NTSF (I can't read it properly because it goes away too fast) then after the screen flash the whole thing again (boot from win 7 or Puppy I choose Puppy again the flash... basically a loop).

Any ideas what I'm doing wron or what the problem is?

Thank You for any replies.

Hey All,

Is there a way to present a path or other block device to a USB port on a Linux server then have that port connected to a USB port of another device (ie USB to USB) and have it look like a flash disk?

I can plug a USB flash disk to a router just fine. But if I wanted a device to access a path off of another device int he absence of NFS or CIFS capability, that would be handy.

In other words, anyway to assign storage to a USB port in Linux? It would be akin to something like SAN with a target and source just with USB.

Cheers,
DH
