If there is data on the drive that you cannot afford to lose, then do not try to fix the drive yourself. I would also suggest that you do not even try to power it back on after it has been dropped, as this is what usually causes the most damage. Whether your drive is an external desktop drive or a small portable one, they all work in the same way. Broadly speaking the inside of a hard drive is a bit like a record player with a mechanical moving needle reading the vinyl record. I can remember the times when playing old vinyl records, once you got scratches on them they never really worked the same again.
So I recommend not to panic, decide on what the value of the lost data is to you. Sometimes it may not be money value but a sentimental one. Once you have decided, then carry out some research online and look at data recovery company reviews. From our experience with dropped drives, the amount of work involved in overcoming the problem would not be covered by the low initial cost that some data recovery companies advertise and therefore the cost would soon escalate.
There is always hope of recovering data from a dropped drive but as you have read, it depends on your actions as to the eventual outcome.
This is a video of a functional Toshiba laptop drive. Using a macro lens, we are able to see what happens when you read or write data to or from a hard drive. You can also see how the hard drive parks the heads off the disks when the power is shut off. This is to protect the hard drive from shocks during transportation.
It’s my first one of these videos so you can see my reflection in a couple of places, when I lean over to send different commands to the drive.
Western Digital want to buy Hitachi Global Storage. The FTC will only allow this if WD sell of some manufacturing capabilities to Toshiba. This seems to be due to some anti-competition type laws. The strange thing is that Toshiba don’t currently make 3.5″ drives, so perhaps we will see some strange Toshiba branded WD drives? Who knows.
Maybe it will be like when Maxtor were bought by Seagate and brought out the STMXXXXXXXXX drives, which were simply Maxtor branded Seagate drives.
Toshiba have recently announced the new GSX series of hard disk drives. With 200GB per platter these 5400rpm drives should see the light of day by the end of the year. There are other notable features such as the new acoustic technology which aims to silence seek operations.
In addition to increasing areal density to 308 gigabits-per-square-inch, the 400GB MK4058GSXincorporates acoustic techniques that make the 5,400 RPM HDD nearly inaudible during seek operations.
Tosh have also announced the new GSY series of drives which will be a touch less spacious at 320GB but spin at a whopping 7200rpm with fast data throughput of 1020 megabits per second.
Toshiba has just announced the 1.8″, 160GB, 5400rpm MK1617GSG drive. Apparently designed for netbooks and other such small machines, it’s a shame that this drive is a tad on the bulky side. at 8mm thick, this drive would be bulging out the sides of a current iPod or MacBook Air. With a SATA interface though, this drive could make for some fun embedded type devices or mods. I would personally love to see one squashed into an eeepc. I also bet that this little baby will be far cheaper than an equivalent solid state drive.
Toshiba announced some breakthroughs in magnetic storage that could theoretically see the 1.8″ hard drives pushing 240GB using two platters. Using a new process which adds grooves to the disc surface, Toshiba have been able to get 120GB per platter. Apparently this process is best suited to small drives such as 1.8″ & 2.5″ drives. Although this would mean a nice fat drive in our iPod, this process is expected to reach the manufacturing process in 2009.
We recently received a white 5G iPod for repair. The problem with this iPod seemed fairly simple. After loading tracks from a windows version of iTunes, the songs would appear in the list as usual, but after playing one or two songs the iPod would stop playing and appear to skip through the rest of the songs. We have seen this sort of issue before, when songs have gone into the iTunes Library but never copy correctly over to the iPod. We confirmed that this was not the case as we were using a fresh iTunes install with only one album in the library.
Another issue we see is when the iPod’s system area becomes corrupt and therefore causes problems playing music. We removed the Toshiba hard drive from the iPod and performed a complete write process on the drive to remove all partition and data information. As a matter of interest we decided to restore the iPod on a Macintosh computer. When we added the sample songs, all was good. They played correctly and we thought problem solved. We had to restore the iPod on a Windows PC to give back to the customer, so we carried out the restore and added some sample tracks. Unexpectedly we were back in the same situation again. The songs would initially start to play but then skip around all over the place. Next on our list of possible fixes were iPod diagnostic modes. These are accessed on this iPod using the following process:
Toggle hold switch on (red) then off (white)
Hold down the menu and center (select) button for a few seconds to reset the iPod
Once the white apple logo appears, press and hold center (select) button and previous (<<) button
From this secret menu we tried a full test (be aware that testing the SDRAM took around 20-30 minutes and shows no activity until it is finished)
These test all passed with flying colours so it was back to the drawing board. Thinking back to the fact that the iPod worked fine when it was Macintosh formatted we decided to try a firmware downgrade. All we had to do was choose a firmware from the list and load it onto our iPod. We tried 2005-11-17 which contains firmware version 1.0 for the 5G iPods. We did have to plug the iPod into the PC and then eject it from the taskbar before the restore utility would work.
Since downgrading the iPod it has worked flawlessly and been playing music non-stop. Apple appears to be ignoring this problem instead of providing an update or even recommending this downgrade option. Hopefully this little guide will save a few iPods from the scrap heap and maybe even provoke a response from the big A. We will have to wait and see what Firmware 1.3 brings.
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.
