Talk:USB mass storage device class

message: Apple Computer's Mac OS 8.5.1 supports USB mass storage through an optional driver.  Can anyone provide any more information regarding this driver? Nerobert (talk) 20:23, 17 August 2010 (UTC)

message: Does it matter if you unplug a USB mass storage device without "Safely removing hardware" or the like?  What happens if you unplug one during a file transfer?  I've never noticed any problems, but these kinds of problems are subtle — Omegatron 03:30, 10 December 2006 (UTC)
replies: text: well, i unplug one after playing maple (i install it into my thumbdrive) and the next time i plug it in, the file is gone! the folder says it's empty, including my phone's backup! someone please help. Ragnaroknike 15:21, 28 July 2007 (UTC)

text: Windows 2000/XP uses Write Behind caching on removable media for some odd reason.  Pulling the usb cable or even pulling the card out of the reader before making it "safe" is a very bad idea.  It is in my experience Windows will write "most" of the data immediately, but last bits won't be written in much as a few minutes sometimes.  Safeing it will cause the write cache to immediately and completely flush.  Windows 98 doesn't use Write Behind caching on removable media by default and is generally safe the pull the usb after you "think" the data is written. 66.114.93.6 (talk) 12:42, 26 July 2008 (UTC)

message: Is the scale to the right of the first image correct, seems like a long device to me. Judging by the Quarter used in the  previous versions of the image, the length should be just above 80mm instead of 100mm. Bergsten (talk) 12:40, 17 November 2007 (UTC)

Since Windows's AutoRun feature works indiscriminately on any removable media, USB storage devices became
This is not true. Windows XP does not use AutoRun/AutoPlay on USB flash disks at all. And I believe Vista/7 also asks before starting anything.

thread_title:  Error in article regarding AutoRun 

message: Having used various external USB drives on various PCs / operating systems I have *always* found them unreliable on large, long-running data transfers.  By large / long-running I typically mean using something like rsync to synchronise changed data between disks, either both USB on the same computer, or both USB on different computers across ethernet or one USB external and one internal (IDE or SATA).
Without exception, various error messages and 'hangs' start to occur after a while and either the rsync fails on lots of files or else the transfer rate slows down enormously because of OS delays while waiting for time-outs or 'resetting' hardware.
I never experience such problems with two internal IDE drives.
The conclusion is that there is something unreliable about implementations of USB when used for large / long-running transfers.  Whether it is inherent in the USB protocol, or ubiquitous across operating systems' implementations (Windows 2K / XP / 7; various Linux) the effect is the same - USB is not reliable for large / long-running data transfers.
Why is this protocol problem never addressed in USB reviews?  Or discussed in articles about the protocol?  Such failures with primary, internal disks would be intolerable.  — Preceding unsigned comment added by 86.179.113.26 (talk) 07:57, 12 June 2011 (UTC)
