Playing a game of catch up, Samsung and Seagate have gone head to head with Hitachi’s big boy by each announcing their version of a terabyte drive. Both drives feature the SATA 3Gps interface. The Samsung offering has only 3 platters opposed to Hitachi’s 5 and Seagate’s 4 which would suggest that it is not only more reliable but may be the forerunner of a future 1.5TB drive (with all that extra space for platters!).
Here is a perfect example of why you should not attempt data recovery on a failing hard drive. This Maxtor 6Y160P0 drive was sent to us after being attached to a PC as a slave and then spun up and down repeatedly in a data recovery attempt. Needless to say the telltale crunchy spin-up was heard and we headed into the cleanroom to check out the damage. It was not a pretty sight. So much of the magnetic coating had been scraped off that there was a layer of soot on all of the components inside the hard drive enclosure. Even after a deep clean, debris and rough edges would wreck a new head mechanism in seconds, rendering any further data recovery attempts pointless.
We received an iPod containing a Toshiba MK6008GAH 1.8″ drive for data recovery recently. The iPod was rattling when inspected so we thought the ipod itself may have been broken. Upon removing the drive we observed that the rattle noise was in fact coming from inside the tiny drive.
We checked if the client wanted us to move into the cleanroom phase of recovery which is more expensive. The client said yes and so we took the drive in for its diagnosis.
After removing the cover the level of damage was very clear. The top disk platter was completely shattered leaving no chance of recovery. The other intact disk was scratched to pieces by the loose fragments of glass that were knocking around inside the drive enclosure. The read/write mechanism had not even left the ramp as you can see in the photographs although it would be clearly contaminated by the glass dust.
Looking at the severity of the damage it is difficult to understand the reasoning behind using glass disks inside such a portable hard drive. We do not know how much shock caused the disk to shatter but the fact that it is possible at all seems strange.
With drive capacity nearing the Terabyte mark, track density increases along with the gap between read / write heads and platters. Therefore are Hermetically sealed drives the the way forward for Manufacturers?

An article on Engadget today predicts that the cost of flash drives (or SSDs) are not going to overtake Hard Drives in cost per gigabyte for many years to come. It gives a nice chart that shows that with the fall in SSD prices, Hard drives costs will continue to fall.
