Purchase at the end of 2008, Seagate 7200.battery for Toshiba PA3384U-1BAS battery
11 500GB drives use occasionally without undue loss of response, the system stuck a few seconds (time ranges), I did not care, that is the system reasons did not worry about, but two months later day, there has been a blue screen of death situation, restart the computer after the hard power, rotation, but can not be detected by the motherboard. Data lost, ask around friends have different opinions, some people say I used improperly, some people say it is my poor power quality (but my power supply is a serious domestic manufacturers licensed 450W), one may Seagate hard “invisible injury”.
Colleagues found similar symptoms in the days following, but the model is slightly different from his hard disk is 7200.11 640GB product. I think this is no coincidence, therefore please CFan detective firm to help me to investigate more thoroughly.

After receiving the case, Detective Alpha case analysis:
Doubt one of the hard drive under normal use conditions, high temperature or vibration will cause hard disk failure rate increased significantly, but only limited to the hard disk damage,Dell Inspiron 700M laptop battery loss of data, power does not recognize is almost impossible happened.
Doubt the two power supply problems are likely to lead to hard disk unusual culprit, but taking into account the reported use 450W authentic licensed power, and there are similar cases in the same period of time …
In any case, our first two points above questions to investigate, if the individual phenomenon to analyze the cause of the malfunction, but if it is the vendor’s “invisible injury” is not a small thing.

Stores unannounced visits to Make note of
“Boss, give me to block 500GB hard drive, you recommend a brand!”
“I recommend that you Western Digital 6400AAKS, compared to the 500GB price gap is small, the performance is very good, how you look like?”
Western Digital ah? I personally like Seagate, Seagate 7200.11 500GB you stock?
“… Be honest and you talk, Seagate’s failure rates are very high, the alleged problem with the firmware, I have temporarily stop the purchase, after all, do not want to take the risk.”
“Oh, like this, I still look to buy it, Xiela!
“There is need to keep you well!”

Official rhetoric
In the store unannounced visits, visits to businesses to reflect the Seagate hard drive failure rates high, but vague, can not make it clear why, it seems that this problem is not the case, so we have issues related to Seagate’s domestic distributor Jianda Grand stakeholders asked the official answer is: “a very small number of Seagate Barracuda 7200.HP Pavilion N5195 battery11 hard drive found a firmware issue that led to the on / off the power may not be able to access the data returned through the analysis of field data, can determine The risk is very low, Seagate believes that the affected hard disk can be used as usual, but Seagate will provide free firmware upgrade (service) “.

Forensics summary
