Bullshit. Its 99% NOT the users "fault." First off, these stupid ext-USB hard drives are effing GARBAGE. And, it is standard fare that they start chirping when they begin failing. And boy do they fail. They are also USB-port-'partial', if you will; behaving sporaticly on one port, only to be [more] consistent on another. But, in my experiences, when they start becoming more particular in their port-preference, its indicative that they are on the decline.
Its particularly annoying that MS has removed from the right-click menu of drives to "Safely Remove" ... requiring that you now find it in the safely remove sys-tray item, which is probably hidden, then to, hopefully, identify the correct device to remove by name or drive letter, in which the latter changes.. Why it's omitted from the menu options when its actually QUITE required is stupid. I say this because although many people are correct in assuming this is acceptable use (and is not stated overtly by mfg to not do it) there is good evidence to suggest its absolutely damaging over time:
1. your write may be corrupted without warning (i.e., stated to be 100% complete within the GUI)
2. removing sans 'safely-remove' and inserting in a ubuntu system will result in the drive being unreadable, 100% of the time. You'll have to re-insert it in a win system and safely remove for it to again be readable by the NTFS viewer (I forget what its called).
More off topic still, switching back and forth with an external enclosure that has firewire and USB, (or possibly just doing the following with just firewire) has resulted in total loss of data (or MBR) on more than 2 occasions for me, resulting in LONG data recovery exercises, and substantial loss.
The bottom line is, the implied "acceptable use" by platter-drives with write cache seems a great degree less reliable than what an end user would expect.
Final note, sata may be hot swappable in nature, however, when I reinserted a dvd-rom back in to my system yesterday, which albeit, is not necessarily a good idea.. (I knew better when I was removing it, less 'wrong' than re-installing it) upon inserting the power cord, my system shut down. It was NOT in the middle of a task.. completely idle. Upon rebooting, my OS drive had failed, to which, I had to do a low-level format to regain usable status (good thing I have multiple systems at home, I feel bad for people who have to trouble shoot without a backup system or two for formatting, getting drivers, or burning my Win7 disc to bootable USB given that Win7 notoriously doesn't read DVD-roms properly during installation).. Once I was back up in running, to my further surprise, my RAID-5 array (ICH10R) had been degraded! And, autonomously was rebuilding - which I thought was nice... at first. After 90 minutes, it showed that it was in a degraded state with a FAILED drive! Meaning, not only did this haphazard act of putting my ROM drive in fail my OS-drive.. but also, literally killed a drive in my raid array! Failing a recovery, I will next do a low level format to it, and try again, which I'd expect to work.
While on my soapbox of shitting hardware.. lets talk about wireless-N. In having tested 3 wireless-N routers in the last 10 days with no other protocols on the network (B,G or A).. I have consistently gotten speed tests that show my old G router has better performance! Better range, better speed! Translation, N fails to deliver in the two arenas it touts as the reason to shell your cash out for. I have gotten slightly better performance of my G router adding hi-gain antenna.
Yup - all anecdotal.. but I HIGHLY doubt that my disappointment of these precise things are the exception.
