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 MK4058GSX incorporates 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.
Finally. A 7200rpm drive with 1TB of storage from Western Digital. (Didn’t we already have one of those?) Anyway, they are touting this as the fastest 3.5″ SATA drive on the market. It does have a 32MB cache and a 5 year warranty so it may be a good choice for those wishing to up their storage capacity. I am starting to warm to Western Digital as their recent offerings seem to be stylish, fast and stable. (And I have one in my iMac that i would hate to have a failure!)
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.
Fujitsu’s new 80-320GB “MHZ2 CJ” drives come with a nice added feature. Not only do they spin at a reasonable 7200rpm, they also have the ability to totally lock you out of your data (And throw away the key). With AES-256 encryption you you can be sure that a forgotten password would wave bye-bye to your data. Currently, AES has yet to be broken in a feasible way, leaving a lengthy brute-force attack as the only option. I question the implementation, as we have seen a number of problems with hard drive passwords which are stored on the drive in the service area. Quite often the passwords become corrupt leaving the user locked out of their drive. The only way to overcome hard drive passwords is by low-level firmware repair, effectively removing the password. This is likely not an option with disk encryption as you would expect a much more robust system.
Whichever way you look at an encrypted drive, it could cause major problems to people needing data recovery. Is it just a clever marketing scheme in a paranoid market or is there some really secure basis for the new technology. I can’t wait to get my hands on one and find out.

What happens to your hard drive once it is replaced under warranty?
This is the question we are being asked by our customers once we have recovered data from their hard drive. Is there a process in place which is used by resellers or drive manufacturers, that ensures your data does not fall into the wrong hands?
Watch this space for further information……..
Disk warrior has long been a favourite utility used by mac support companies and enthusiasts to analyse and repair Macintosh disks. It is favoured mainly for it’s simplicity and many features including data recovery.
As a data recovery company we have received many mac hard drives from clients who had previously used Disk Warrior to attempt to gain access to their data. In some cases the particular hard drive being examined was too severely damaged for Disk Warrior to be of any use. In other cases Disk Warrior was used but the data left afterwards was corrupt and not accessible.
The problem is not so much the utility itself, but the lack of a users understanding of how powerful this utility is. This is a quote used on Alsoft’s website that can be misleading.
“ Simply click the rebuild button and Disk Warrior goes to work ”
In any data loss situation writing to the hard drive that has your lost data is something that should never happen, as it is this writing process that can do more damage than good. If you allow DiskWarrior to write a repaired structure to your disk, you lose any chance of getting back data what was missed out. If the rebuilt data is damaged, the disk will be in a worse state than the original failure.
We recommend that you read the documentation that comes with the utility carefully and fully understand its capabilities.
The next battle in the war on SSDs may have just begun. Apparently Seagate are convinced that SSD makers such as Samsung and Intel are violating some of Seagate’s (and Western Digital’s) patents. The wizardry which relates to the way a storage device communicates with a computer is at stake, even though Seagate themselves don’t appear too taken with an SSD based future. CEO Bill Watkins is quoted as saying, “realistically, I just don’t see the flash notebook sell.” I would have to agree with that at the moment. Cost per GB, reliability and speed are among the many drawbacks currently facing solid state drives when compared to traditional hard disk drives. Once these issues are resolved then the need for regular backups will become all the more important in my eyes at least. There are currently many ways in which we can resurrect a failing hard drive but next to no ways to recover a failed SSD.

It seems the backlash may have already begun. As we expected the current batch of SSDs are no match for the long perfected hard drives. Reports of customers returning solid state laptops are apparently hitting the 10-20% mark. I would like to think that a new revolutionary data storage medium gets into the market place before SSDs really take hold. I have an SSD in my EEE pc which is fine but I can’t help thinking a 30GB 1.8″ drive would have been far more versatile. Let’s see what developments appear in round 2. Will the SSDs fight back? (I think not…)

According to Engadget, BiTMICRO have announced a new solid state drive which packs in 1.6TB of storage into a 3.5″ form factor drive. The E-Disk Altima E3S320 promises sustained data transfer rates of up to 230MB per second and are also expected to be available in more modest 16GB varieties. Engadget suggest remortgaging your house which may not be too far wrong if current SSD costs are anything to go by.
