Titolo: cambio hard disk smart failure

a volte succede che il pc non riconosce l'hard disk che, quando 
riconosciuto, funziona blillantemente. Quando è successo l'ultima volta 
ho tolto e rimesso i cavi ed ha rifunzionato. Ogni volta che accendo il 
pc il bios mi dice di sostituirlo perchè "smart failure".
con speed fan ne ho preso le caratteristiche (wui di seguito).
Essendo da 320 gb mi spiace cambiarlo. Cosa mi consigliate, stà per 
rompersi o sono falsi allarmismi?
Your hard disk is a MAXTOR STM3320820A with firmware 3.AAE.
The average temperature for this hard disk is 39C (MIN=30C MAX=48C) and 
yours is 41C.
Your hard disk's S.M.A.R.T. attributes are now being analyzed and a full 
report about the reliability, health and status of your hard disk is 
generated:
Error:	  	Reallocated Sector Count has reached its threshold. Current 
value is 1 and threshold is 36.
According to S.M.A.R.T. specifications, your hard disk is failing and 
needs to be immediately replaced. Backup your data as soon as possible.
Warning:	  	Reallocated Sector Count reached, in the past, its 
threshold. Worst value is 1 and threshold is 36.
Your hard disk is now being compared to real data used to define normal 
values for your specific hard disk model. This way, the analysis can 
automatically use proper operating ranges. The images give you an idea 
of how each attribute is within such range. Current and raw values are 
shown for easier reference for experienced users. There are 1742 hard 
disk models in the current archive.
	 	Attribute	 	Current	 	Raw	 	Overall
  		Raw Read Error Rate		117		131895242		Very good
  		Spin Up Time		95		0		Normal
  		Start/Stop Count		100		42		Very good
  		Reallocated Sector Count		1		51745		Watch
Warning: Reallocated Sector Count is below the average limits (100-100).
  		Seek Error Rate		41		1522 273 18415		Watch
Warning: Seek Error Rate is below the average limits (46-100).
  		Power On Hours Count		99		1128		Normal
  		Spin Retry Count		100		0		Very good
  		Power Cycle Count		100		62		Very good
  		Unknown attribute 187		1		65535		Watch
Warning: Unknown attribute 187 is below the average limits (90-100).
  		Unknown attribute 189		100		0		Very good
  		Unknown attribute 190		59		496 10534 41		Good
  		Hardware ECC Recovered		77		116939508		Good
  		Current Pending Sector		100		17		Very good
  		Offline Uncorrectable Sector Count		100		17		Very good
  		Ultra DMA CRC Error Rate		200		21		Very good
  		Write Error Rate		100		0		Very good
  		TA Increase Count		100		0		Very good
NOTE: not all warnings are reflected on fitness and performance overall 
values as relevancy is based upon the settings from the hard disk 
manufacturer who is the best entity deputed to define such relationships.
NOTE : your hard disk has 51745 reallocated sectors (this value is very 
large and your hard disk should be replaced). Hard disks do have spare 
sectors (usually from 256 up to 1024) used to replace bad ones. This 
remapping operation is transparent to the end user. Anyway, this can 
lead to degradated performances (because remapped sectors are in 
different places of the disk than the original ones and the head needs 
additional moving). If reallocated sectors grow over time, you might 
encounter some serious troubles. A backup of the most important data is 
suggested anyway.
NOTE : your hard disk has 17 pending sectors. Those are sectors that 
couldn't be properly read and that the hard disk logic is waiting for a 
write operation to try to remap to a spare sector (if available). 
According to the Reallocated Sector Count attribute, your hard disk 
seems to be either low or out of spare sectors. A simple disk surface 
scan won't be enough to force the remap operation. You need a read/write 
surface scan to remap the sector. The best option should be a tool that 
knows about what should be read from that sector so that it has some 
option to apply the best fix to the missing data.
NOTE : your hard disk has 17 offline uncorrectable sectors. Those are 
sectors that an offline scanning found as unreadable. Offline scanning 
is a process that can be automatically started by the hard disk logic 
when a long enough idle period is detected or that can be forced by some 
tool. Those unreadable sectors are identified and the hard disk logic is 
waiting for a write command that will overwrite them to try to remap 
them to spare sectors (if available). According to the Reallocated 
Sector Count attribute, your hard disk seems to be either low or out of 
spare sectors. A simple disk surface scan won't be enough to force the 
remap operation. You need a read/write surface scan to remap the sector. 
The best option should be a tool that knows about what should be read 
from that sector so that it has some option to apply the best fix to the 
missing data.
The overall fitness for this drive is 0%.
The overall performance for this drive is 62%.

Sulla predizione imho nulla può dirsi con certezza ma la prudenza
resta.
Cmq, l'Ali è sufficientemente potente ?
Cambia molex di alimentazione e sostituisci con uno nuovo il cavo Ide.
