USB storage media – data integrity issues on linux

I’ve always been somewhat paranoid about verifying data backed up to removable media, so after copying stuff to a USB flash drive or portable HDD, I invariably unmount the drive, remount it and diff -q the stored files with the originals.

Years ago I discovered that (at least with the equipment I’ve got), I was seeing bit errors at something on…

What is the replacement of the floppy

While CD (and to an lesser extend DVD) disks have reached the price-point of the floppy, they have one significant downside, it is WORM (Write-Once Read-Many) media, allowing it to be used only one single time, and you need to be explicit in writing the data to the actual media (you need to burn it.)

While CD-RW solves the “use only once” problem, it is…

Ubuntu – How to automount an external drive at a preconfigured mount point?

Normally, when I attach an external USB drive to my Ubuntu system, the filesystem on it are automounted to /media/label. However, I’d like the filesystem to be mounted at a mount point of my choosing. I’ve added a line like this to my /etc/fstab:

Is it bad to defragment a USB Flash Drive?

If I defragment my 8 GB Kingston flash drive, will it decrease its lifetime?

Answer [by Zds]: Is it bad to defragment a USB Flash Drive?

If you have not yet done it, the answer is, “yes it does, don’t do that”. However, most likely one defragmentation cycle consumes just 1-5% of the lifespan of the USB stick, so you’re hard pressed to notice. The exact…

What is the danger of inserting and browsing an untrusted USB drive?

Suppose someone wants me to copy some files to their USB stick. I’m running fully-patched Windows 7 x64 with AutoRun disabled (via Group Policy). I insert the USB drive, open it in Windows Explorer and copy some files to it. I do not run or view any of the existing files. What bad things could happen if I do this?

What about if…

Booting Linux off USB pendrives

Booting a Linux system off USB Pendrives is one of my favorite things.

On a laptop we have the following advantages,

The Harddisk can be shutdown and that reduces power consumption (hdparm)

The system heats lesser and the fans are triggered less frequently

The system can take more shocks (a bumpy backseat taxi ride)

With old workstation hardware,

Can be used for…

Is there a way to power down a USB device using software?

Is there a way that I can power off a (specific) USB device completely using software from a Linux machine?

I want to use this to power off (so that the LED is off) a (single) USB stick.

Do you know any method to achieve this? E.g. using /sys/bus/usb or the like?
