Creo que sería bueno promover el uso del foro, pues no he visto mucha
actividad por ahí, es más se me acaba de perder la dirección del foro¡¡¡

>>  Buenos dias lista.
>> Este articulo lo tome de StorageReview.com, tiene que ver con el trato que
>> se le da a un disco duro y los problemas que esto trae. Tambien hay algunos
>> concejos locos para "talves" hacer trabajar un disco duro malo lo suficiente
>> para sacar la informacion. Esta en ingles, si alguien lo quiere traducir y
>> despues reenviarlo bueno, yo no tengo tiempo.
>> 1-Drive Bumps:
>> One of the most common causes of failures happens as soon as the
>> installation phase: the dreaded "bumps".
>> When you hit a hard surface (such as your case) with the harddrive (during
>> installation, for example), a "little" bump will very likely generate a
>> shock of several Gs (probably more than 100Gs!), making the head scratch the
>> disk surface and creating little indentations. The indentations and the tiny
>> material particle generated both *will* (not may) cause problems sooner or
>> later (maybe not noticeable before a year or more!).
>> 2-Drive Orientation:
>> Modern drives should suffer no ill effects from variable mounting
>> orientations. There is some consensus that it is best to mount drives with
>> at least one of the drive's sides parallel to the ground.
>> It is also safe to change the mounting orientation even after the drive
>> has been established in an initial orientation. In older drives, according
>> to StorageReview member Mickey, changing the mounting orientation once it
>> has been established can cause failure if there was uneven bearing wear.
>> Reasonably modern drives should not be troubled by this problem.
>> 3-Death Clicks:
>> Simply put, the "Clicks of Death" are a very bad sign for the health of a
>> HDD. They are loud clicks which appear mostly while the drive is seeking.
>> They most probably mean a failing drive, ready to develop bad sectors and
>> die. Start backing up your data and prepare for RMAing the drive if you are
>> still in warranty.
>> Some drives click once or twice when either powered up or powered down.
>> These are normal sounds. Sounds of your drive clicking repeatedly are cause
>> for concern.
>> 4-Data Recovery:
>> First, check the obvious: jumpers, power cables, IDE (or SCSI) cables are
>> firmly seated.
>> If you are sure that your drive has failed, shut down the drive. You need
>> to make an honest assessment about how much you value your data. If you
>> absolutely *have* to get the data back, do not attempt any homebrew
>> recovery methods. While some are not destructive, the more you use a failed
>> drive, the harder it becomes for professional data recovery firms to get
>> back your data (and thus, the more it'll cost). A good place to start for a
>> list of recovery firms is to visit your HDD maker's website. They usually
>> have a recommended list of firms; this ensures that your warranty is
>> preserved.
>> If I had to list a few of the more common tricks, they would be as
>> follows:
>> Drive refuses to spin up (no noises):
>> - Clean contacts between board and motor.
>> - Make sure the board is not shorting out against the drive.
>> - Check power cables, connectors, etc.
>> - Board swap, trying to match make, model, vintage.
>> Drive refuses to spin up (chirps or other noises):
>> - Tap drive (or firmly shake it) while it tries to spin.
>> Drive spins, but loudly clicks/chirps:
>> - Freezer trick: pack drive in ESD bag, tape shut, shove in freezer for a
>> few hours (or overnight). Remove from freezer and immediately plug into a
>> known working system as a slave drive, then hope it spins up and behaves
>> long enough to copy data.
>> These are the more generic "tricks" that are unlikely to further damage
>> your drive.
