ST31000333AS bad behavior after a resurrection

Hi all!

 

A couple of months ago my 1Tb hard drive died (i heard loud head clicking and OS stopped responsing, after a reboot it happened again and again). I restored almost all files (when I booted with Acronis Disk Director, it was possible to copy the data about a half an hour before head clicking began). Then I had no time to manage with it, so the drive just lay on the shelf about a month. Then I was going to take it to the service center, but decided to try to connect it once again. I formatted it - and my new OS saw it. I ran some surface tests and they came through. So, it's not dead... But there are many slow blocks (about 200 with 200-600 ms access time and more than 2000 with about 100 ms access time, needless to say about average access speed - it's about 60Mb/s in the middle and in the end of disc) and SMART parameter HighFlyWrites rises when writing (it's value is 1 now, threshold is 0, raw value is about 2500). As I know, this parameter shows how much times head was too far from disc's platter when trying to write. Maybe it's not so bad, but in case that earlier there was a disc crush because of head malfunctions... So I took my drive to the service center - and they said that it's totally ok after testing so they won't change it for the new one. Are they right and such a behavior of the hard drive is really within normal limits? If yes - i would be glad any advices, maybe any stress test for the drive to make it show it's real face...

 

Sorry for such a large post. I'm just very upset with this situation...

If you can get the drive to fail SeaTools, then you will have a valid Test Code that will qualify for an RMA.

Otherwise, try HDD Regenerator:

If any head is weak, then this will be a torture test for it. If OTOH you need to recover any data, then you should clone your drive as quickly as you can. In such cases you should avoid utilities such as HDD Regenerator or Spinrite. These utilities repeatedly hammer away at bad sectors, potentially accelerating the failure of a weak head.
