Hi , I’ve got a 1T my passport USB 3 and im using it for about 2 years without any problem , but since 3 months ago I got that my hdd gets disconnected and reconnected when im coping or cutting a file from it to my PC or laptop or what ever device it is , I asked and searched a lot till I used HD Tune Pro to see if all the Health Status were OK or was there a problem with it , as it was expected I found out that so many options were either red which meant failed or yellow which meant warning , so I used Hard Disk Low Level Format Tool and format it and it took about 28 hours ( forgot to say , the transfer speed is so so so low its about 4 mb/s )
after that I checked it with HD Tune Pro again to see if the problems were solved or not , I saw that so many of them got solved and were OK except these 2 :
1.Reallocated Sector Count (Description : Number of retired sectors : 561 - Status : The drive has damaged sectors)
2.Reallocated Event Count ( Description : Number of sector replacement operations : 58 - status : OK)
the first one was red which as I said meant failed and second one yellow which meant warning
so I searched and searched and searched again to see how to solve bad sectors and I found that HDD Regenerator is a good thing as they said , so I got it and used it , there are there options available when you chose your drive:
1.Prescan (Show bad zones)
2.Normal Scan (with / without repair)
so I chose the first one and started scanning and after a delay my hard got automatically disconnected and after a while connected again , I continued the process and saw that after the disconnection and reconnection the program had found a bad sector , I continued some more times and saw that every time that a new bad sector is detected the hard reacts that way so I thought maybe its better to go for second option and normal scan it so I chose it and there were 3 options there :
1.scan and repair
2.scan , but do not repair ( show Bad Sectors)
3.Regenerate All Sectors in a range (even if not bad)
I gone with the first one and the same thing as prescanning happened so I thought maybe my drive gets hurt from this much connecting and disconnecting and I stopped the process , I gone with the 3rd option but it takes 350 hours ( LOL) I don’t really know what to do to repair this bad sectors
I’d appreciate to get your help
and something else , is this low transfer speed because of bad sectors or there is a problem with the speed of spinning ?
I used Western Digital Data Life Diagnostics and in the Quick test it fails and also it is shown fail in the smart status too before testing it , the error that appear when quick test fails is :
06-Quick Test on drive 2 did not complete! Status code = 04 (Unknown failed test element), Failure Checkpoint = 96 (Unknown Test) SMART self-test did not complete on drive 2!
Should I go any further for testing I mean , Extended test and Write Zeros?
