Hoy día Seagate ha comprado la división de HD de Samsung y en mi opinión ya no tienen la misma calidad.

This is my attempt to help those contemplating over the upgrade. During my research I simply couldn't find a thorough description of the procedure. These hard drives (HD-s from now on) are exceptionally well engineered, so the effort is definitely worth it!
Why should end-users upgrade the firmware? The answer is simple; using them with the old firmware might result in serious data loss later, as described by Samsung. (Certain people believe that drives with manufacturing date later than February 2011 dont have this issue; mine was manufactured in 03/2011 and I still did the upgrade, just to be safe.) Fortunately Samsung released the improved firmware on its website called F4EG (a zipped up exe file):
[Hah, links don't work on Amazon. Do a web search for F4EG on Samsung's site]
But the real hurdle is that you have to boot in DOS to perform the update! You could do so using a floppy drive, but not many of us have those lying around anymore, therefore my guide gives pointers on how to perform the upgrade using a USB thumb drive.
Updating the firmware leaves the existing data intact on the drive; also, the drive comes unformatted; best to do the formatting on a Windows 7 computer, or use a modern formatting utility instead of Windows XP-s built-in one. Then, you can use a freeware utility such as SpeedFan or HDDScan or HDTune Pro to check for bad sectors/issues. The executable firmware file works automatically and only selects the correct drive, no user direction required. Also, the Samsung firmware upgrade MIGHT not run if your drive has the latest firmware installed already by the factory.
The updating procedure using external hard drive dock connected through either USB2.0 or eSata to my PC did not work... I had to disassemble my Dell Zino HTPC: remove the Blu-Ray ROM, HD caddy w/ orig. HD) and connect the Samsung HD directly to the motherboard (Before disassembly I booted into the BIOS by hitting F2 on keyboard of my Zino, changed boot order to "USB first". There might be other steps needed for other PC-s.)
I used one of my newer USB drives (my 16GB Kingston DataTraveler), I installed unetbootin on my PC. Then using unetbootin I installed FreeDOS onto the USB stick, downloaded and copied the Samsung firmware (exe file) into the same folder with FreeDOS (that is, into the root directory called "freedos").
Download software mentioned above and follow instructions from these two links:
[Do a web search for unetbootin. You'll find it on sourceforge.net] (click "Download for Windows" on top of page).
[Do a web search for freedos. You'll find it on freedos.org] (fdbasecd.iso is what you'll need to download).
Boot your PC up with the Samsung HD installed; repeatedly hit F12 on keyboard to access boot order.
Navigate to the "USB (name of USB stick here)" line with the arrow keys, hit ENTER
Next screen is the "Unetbooting" screen, select fdos, hit ENTER ("freedos" can't be selected, ironically...)
Select the "Freedos Safe Mode (don't load any drivers)" line from the next screen, hit ENTER
Check the exact DOS name of the firmware file by typing "DIR" after "A:\" first. (This came handy to me, since the firmware file I originally named "F4EG.EXE" was renamed to F4EGEX~1 in DOS!)
If you can't see the F4EG file in the "A:\" directory, switch to the C directory by typing "C:" following the "A:\" and hitting ENTER
Next, type the DOS name of your firmware after "A:\" (or "C:\"...), hit ENTER
There will be a few messages displayed:
"Now updating code"
"Please wait for a while"
"Download completed successfully" (followed by the S/N of the HD in brackets)
Reboot PC to finalize upgrade. You can run the firmware patch repeatedly on new drives if you power off and reboot. The update itself takes less than a minute.
Important: the "Download Completed Successfully" message is pretty much the ONLY confirmation on a successful firmware upgrade! Based on Samsung's own update instructions, the firmware version number does not change at all (Samsung dropped the ball on this big time...).
I hope this helps someone out there! :)
It sounded like an airplane taking off and crashing abruptly. I turned off power immediately and didn't want to risk damaging my other components. This whole order not only wasted my precious time, but also put me in a precarious situation. To make a long story short, let's just say thank god Amazon got a great return policy, but my problem is still not solved since now I have to source another drive.
All in all, very dissatisfied with the purchase. If there is just a thin layer of bubble-wrap and using a smaller box like 1A, we would be all happy.
Either the two "defective" drives are actually *good* but have bad (or badly calibrated) internal sensors, or they're bad and are more likely to fail soon. I'm not taking the risk. If you buy these drives, I suggest running a S.M.A.R.T. check on them before and after you format them.
--- EDIT ---
Now I've bought 5 of these drives and returned 2. Of the 5:
* 2 have zero SMART errors (I kept these)
* 1 had a G-Sense Error Rate in the tens of thousands after I formatted it (and had a Program Fail Count Total in the hundreds); returned this one
* 1 had a G-Sense Error Rate in the tens of thousands after a format; returned this one
* 1 had a G-Sense Error rate of 15 after a format and a ProgramFailCountTotal of 349; kept this one
I got tired of returning these drives that have SMART errors, so I kept the last one. Hopefully it won't fail (or fail out of the RAID array because of the increasing SMART error counts). Either the G-shock sensors inside the drive are too sensitive and the drives really are "OK" or the drives will indeed fail quickly. I'd appreciate some comments by Samsung. If the two error rates I mentioned above don't indicate premature drive failure, then I'd like a firmware update to the drive (or a utility that can disable those two attributes) so that my RAID array won't think it's failing prematurely.
These disks have been functioning quietly and flawlessly since purchased over six years ago!
