Jumper Settings for Toshiba 2.5" Hard Disk Drives

Articles / 2010-11-23

Toshiba’s 2.5″ hard disk drives can be configured as either master or slave units. Master configuration is used for all single drive applications, and master or slave configuration (only one of each per port) is used for two drive applications. Use the information in the following tables for information on how to set Master/Slave jumpers.

Jumper settings for Toshiba PATA drives

The following jumper information applies to Toshiba’s current line of Hard Disk Drives:
Master configuration is obtained by setting jumpers B, C & D open (no jumper). Slave configuration is obtained by setting jumpers C-D. When B-D jumper is installed, the drive is configured as cable select. If pin 28 = Low, the drive is master. If pin 28 = High, the drive is slave.

Cheap Hard Drive Recovery

Articles / 2010-11-18

Are you looking for a cheap hard drive recovery service? Data loss can occur on any device that stores data. Although any loss of data, even a simple misplacement, is by definition technically a loss, what we are primarily concerned with is the permanent loss of data that is important to your business’ ongoing success.

Let’s first take a look at people’s questions:

1. Cheap Logical Hard Drive Recovery

I have two USB externals drives. One is my backup drive. The other I just bought and was formating it to NTFS. The full format was taking a long time so I aborted the format and used the quick format. Everything went fine.
I then went to copy some stuff to the backup drive but it said it was not formated. My heart stopped then I said a few choice words. All my pictures for the last 1.5 years is on there. I could not do anything to the drive until I format, so I went ahead and did a quick formate. I am using Vista and the FAT32 option was not there so I formated to NTFS. I think the drive came formated to FAT32. I have no idea how the backup drive got formated. I guess I must of done something. Since the format I have not written anything to the hard drive.
I got a program form Diskinternals. It took about 4 hours to scan. It found around 350gig. It then took another 4 or so hours to copy to my new drive. All the files were corrupted.
Now for my questions:
1. Can the data still be recovered if the drive was FAT32 and then formated to NTFS?
2. Would it help if I formated it back to FAT32?
3. What would be the best software to try to recover my data?
4. Any other thoughts or ideas?

To solve this problem, the cheapest method is to purchase a advanced recovery software and recover it yourself. Connect your computer to a working PC and scan your HDD. In fact, if you know how to send an e-mail you can find all of the data from a crashed disk drive. With this powerful hard drive recovery software you can easily:

Recover files even if emptied from the Recycle Bin
File recovery after accidental format, even if you have reinstalled Windows.
Disk recovery after a hard disk cras
Get back files after a partitioning error
Get data back from RAW hard drives
Recover documents, photos, video music and email
Recover from hard drive, camera card, USB, Zip, floppy disk or other media

2. Cheap Physical Hard Drive Recovery

After moving, my backup drive no longer works. I’ve tried two enclosures and the drive isn’t making a sound so I assume it is an electronics problem not a mechanical problem. I also have a drive that fell off my desk, it does click so I assume it is a mechanical problem. Both drives contain my backups and photos. I would like to recover the data from both these drives. Both are Seagate 7200, one is .11 and the other is a .10. I think I have about 1TB of data between the two.
What is the cheapest method of recovering the data? Send it to a data recovery company (recommendations?) or try switching the platters myself in a makeshift clean room?

Logic board (controller) failures.

Broken power/data connectors (requires fine soldering).
Spindle/arm driver chip failure (requires replacement of either a logic board, or a chip; additional repairs may be needed depending on the true cause of the problem).
Head block pre-amplification failure (platter box must be opened).

Moving parts failures.

Head crash.
Spindle bearing seizure or spindle motor failure.

Firmware corruption (requires special software and sometimes special connection arrangement).

In case of the massive damage, there is no point in attempting the do-it-yourself type data recovery at home. There is little you can do to repair a physically damaged device without the special equipment. In this case, you need a data recovery lab.

Solid State Drive Vs Hard Drive Vs USB Flash Drive

Articles / 2010-11-18

Solid state drives (SSD): used in the enterprise are data storage devices that use non-moving fl ash memory technology rather than rotating magnetic disks or optical media. SSDs are compatible with traditional hard drive interfaces, such as SATA or SAS, and have a familiar hard drive form factor, such as 3.5-, 2.5- or 1.8-inch.

USB Flash Drive: consists of a flash memory data storage device integrated with a USB (Universal Serial Bus) interface. USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk. Most weigh less than 30 g (1 oz). Storage capacities in 2010 can be as large as 256 GB with steady improvements in size and price per capacity expected. Some allow 1 million write or erase cycles and have a 10-year data retention cycle.

USB flash drives are often used for the same purposes as floppy disks were. They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because of their lack of moving parts. Until approximately 2005, most desktop and laptop computers were supplied with floppy disk drives, but most recent equipment has abandoned floppy disk drives in favor of USB ports.

USB Flash Drives Vs Solid State Drives
Both USB flash drives and SSDs use NAND fl ash memory. However, it’s the quality of NAND used—as well as the controller and interface involved—that separates a simple USB fl ash drive from an enterprise-class storage device, like those found in blade servers and external storage systems.

Solid State Drives Vs Hard Drives
Today’s SSDs are different from hard drives when it comes to data storage. SSDs are sophisticated storage devices that use non-moving memory chips, mostly non-volatile NAND fl ash, instead of the rotating magnetic disks found in hard drives. Hard drives can take the data directly from the host and write it to the rotating media. In contrast, SSDs can’t write a single bit of information without first erasing and then rewriting very large blocks of data at one time (also referred to as P/E).

Because SSDs and hard drives have different strengths in terms of effi ciency, they complement each other and can co-exist. SSDs deliver ultra-fast random data access (inputs-outputs per second, or IOPS, performance), low power consumption, small size and high physical resilience (due to no moving parts)— but they cost more. Hard drives provide fast sequential data access with high capacity, endurance and reliability at a much lower price.

Samsung Solid State Drives Overview

Articles / 2010-11-16

A solid-state drive(SSD) is a data storage device that uses solid-state memory to store persistent data. SSDs are distinguished from traditional hard disk drives (HDDs), which are electromechanical devices containing spinning disks and movable read/write heads. SSDs, in contrast, use microchips and data is retained in non-volatile memory chips and contain no moving parts. Compared to traditional HDDs, SSDs are typically less susceptible to physical shock, quieter, and have lower access time and latency. SSDs use the same interface as hard disk drives, thus easily replacing them in most applications.

With faster boot-up time, file searches, app start-ups, and less downtime and power usage, you’ll know why Solid State Drives are the best choice, and where hard drives got their name.

Top 10 reasons why to choice Solid State Drives:

Speed Up Your Boot-Up
Zip through File Searches
Trim File Transfer Time by Almost a Third
Start Applications in Seconds
Double File-Compilation Power
Cut Downtime by Half
Reduce Power Consumption
Master Multitasking
Cut Video-Editing Time
Take it Anywhere

PRML
Partial-response maximum likelihood. Data is stored on hard drives as a tiny area of magnetism for each bit. As more and more data is squeezed on a disk, the magnetic areas become closer and closer and may affect one another. PMRL is a set of steps applied to data read from the disk. It removes probable errors and produces valid data from the tightly packed bits. PMRL allows an increase of up toe 30 % in the density of data on the disk
