Strange new HDD behaviour :(

i have a similar problem with my seagate 500g hdd. use it as slave and every now and then it just disappears from explorer until reboot. when all the issues with these drives was going on, i checked to see if mine was one of those affected and it was not. i also use it as my default download drive and occasionaly my download aborts , because it can't find the drive. running win7 ult 32bit.

You probably looked at the wrong list like many other people. What is the model & serial number?

actually , I went to the seagate website and had to enter my model details and received reply that my drive was not identified as having a firmware issue.
will get back to you on the exact details of my drive (at home).
 
Also have a 1.5 Seagate. Same issue and my firmware is fine. In my case the problem seemed to be the external casing I was using. The drive is now inside my PC and the "klunking" and 5 sec delay for spinning up has stopped. Perhaps plug it in directly and see if it acts the same?

EDIT - That is if the drive is in an external casing ...
 
well its definitely the drive.. unplugged 2 other drives and the dvd rom so its not the power... and started a few unrars to make the disc busy... oh and the drive is in the pc.. not a casing...

lol and behold watching the performance graphs, you see the reads drop right down to nothing as it clunks.. and then comes back up again.. so its going back to pc international this week :)

thanks for all your help!!

That does not always work, seen other cases here on the forum where people thought the firmware was fine according to that site but it was not.
 
SD1A is the latest firmware for the ST3500320AS... i only know this because i updated the firmware on one of my drives yesterday :)

yep. i went to the site as well yesterday just to check if there was any later firmware. no luck:cry:

there was something wierd about the seagate tools that i downloaded and installed yesterday. it picked up two instances of the seagate drive in question but my other drives all appeared once:confused:

Ya i think the seagate drive diagnostics is buggy.. i had the same thing.. duplicates of the drives showing up in it.. lol i wish i had that much hard drive space :)
 
dinkd,

Try booting with a linux livecd and see how the drive behaves then.
 
had the same problem with a 500gb seagate 1 month after starting to use it. had the drive in my machine with about 2gb stored on it for 3 weeks and all was fine. i then decided to get rid of my ide aand save everything to the sata, it almost filled it up. thats when the auto power off started. solution: i deleted the whole partion, partioned it to 65gb for os and 400gb for data and it never gave me anymore problems. dont fill it up to the brim. use wd to store data and seagate for system use.

wierdly enough, mine was fine when it was the master. when i got my 1.5 tb wd, i put this as the master and used the seagate as data and that's when the problem started. i also have another wd 200g ide (2 partitions) for data which gives no problems. starting to think like ponder - win 7 issue?
 
hmm not for me.. the problem occurs when in the bios so not even windows.. and the drive had all of 100gb on it so it was no where near full! going to try play around with it tonight.. failing that, its going back tomorrow :)
 
I have identical drives and motherboard and the identical issue. The drives spin down after a while; when I access the array they do the klunk noise while they spin up. I've only noticed this behaviour (I don't consider it a problem) since upgraded from Vista to Win7. I suspect it's a new setting on the sata controller driver implemented recently by Intel. Install the Intel Storage Matrix thingy and look around for power-down options in it.
 
the problem i have is the drive spins down in the middle of intensive reads...

check the attached graph from the perfomance view... the green being constant activity.. the drop in it coincided with one of the "klunks"
