To help determine your system’s USB capabilities you can download a free USB evaluation utility from the following site: www.usb.org
This program will examine your system and inform you of your computer’s USB capabilities.
For a general rule, if your PC was manufactured before 1996, it probably does not include USB. If the machine was manufactured in 1997 or later, it may support USB 1.0 . Most computers manufactured after 1998 support USB 1.0. Systems available since 2001 probably support USB 2.0.
With some PCs, you may need to connect an adapter (PCI or CardBus) to connect USB peripherals. Read your system documentation if you’re not sure there is a USB port.
Usable storage capacity
Disk array capacity that is usable for data storage (vs. for mirroring or parity data). For example, under mirroring (RAID 1 and 0/1), usable storage remains a constant fifty percent (half of storage is always used for redundancy). This is in contrast to other RAID levels such as RAID 5, in which usable storage capacity is determined by the formula of “n-1”. “n” is the total number of disk drives and “1” is the number of disks worth of capacity used for parity (redundancy) overhead. So, as the number of disks in the array grows, the usable storage capacity percentage increases in relation to parity (redundancy) information.
Is there any program that logs the CPU usage of all programs? I want to know, over a period of one month, which programs use the CPU more intensely. Solution: Windows has this built-in. It’s called the Performance Monitor. Create a data collector set to start collecting performance data.

With the holiday season quickly approaching, many of us are looking forward to spending time with our family and friends. These special times, which used to be captured on film, are now recorded digitally on a video recording device or a camera. It has revealed that the top causes of memory card disasters from digital camera users desperate to recover their memories.
1. Reformatting
Users often forget that reformatting a memory card will remove all the files stored on it including protected pictures and print orders. This data can only be retrieved by experts so Ontrack advises users to think again before you reformat.
2. Overwriting
A common mistake is the accidental overwriting of images held on camera memory cards with new photos. It’s easily done. So check, check and check again that you’ve successfully transferred your images onto your PC, laptop, CD or DVD before taking new pictures.
3. Cracked and damaged media
Packing memory cards into overstuffed suitcases can result in them becoming bent or damaged on the journey home, making them unreadable. Wrapping cards in clothes and placing them in the middle of your case offers some degree of protection in transit and helps ensure the safety of your pictures during your return trip.
4. Burnt media
Leaving memory cards in an elevated temperature environment – close to a heat source such as a radiator or oven – will increase the chances of failure. Heat is unlikely to cause damage to the digital photos on the memory card but may stop the card from being recognized in a card reader.
5. Holiday injuries
For those of you that opt for a tropical vacation instead of a snowy week with the in-laws, digital cameras often get dropped in the sand or splashed with water around the pool, damaging smart media to the extent that photos can’t be viewed. Only an expert can recover digital images from smart media damaged in this way, so users should be careful to keep digital cameras in padded and watertight cases to keep them safe.
Many hard drive failures are caused by problems with the PCB(HDD can’t spin; PCB board/chip be burnt; PCB interface broken; etc). If your hard drive does not spin when powered on, PCB replacement may allow you to recover your data. PCB replacement will not fix all hard drive failures, however, and like most other do-it-yourself repairs, it may void any remaining warranty on the drive. This process should be used only as a last resort after all other options have been exhausted. If you are not comfortable performing repairs yourself, many data recovery companies will perform this task — for a fee.
Before Repairing Hard Drive PCB Circuit Boards You Should Know:
Instructions of Repairing Hard Drive PCB Printed Circuit Boards:
1. Confirm that the PCB actually needs to be replaced. If your hard drive spins when powered on or makes clicking noises, the fault is mechanical and will require professional data recovery. If the drive does nothing when powered on or shuts off intermittently, the PCB may be at fault.
2. Locate a suitable replacement PCB. To do this, you will need the model number of the PCB, which is usually etched somewhere on the board itself. To remove the PCB, simply remove the screws that fasten it to the drive and carefully disconnect the ribbon cable. Many hard-drive manufacturers use specially shaped star or hex screws, so be sure to use the appropriate screwdriver to prevent stripping. Tearing the ribbon cable will render the drive unrepairable, so be gentle; it should come free with minimal force.
3. Purchase a replacement PCB. These can often be difficult to find, though many online resellers offer a wide variety; be sure to contact as many vendors as you can. You will need an identical board, both in physical shape and size as well as model number; substituting different boards may cause permanent data loss.
HDDZone.com is recommended, they provide all kinds of hard drive PCBs including Seagate, Maxtor, Western Digital, Samsung and others with worldwide free shipping.
4. Connect the replacement PCB. Gently connect the ribbon cable; make sure that it’s fully connected before mounting the PCB to the drive with the screws you removed before. Be sure to mount the PCB exactly as the original was mounted.
5. Test that the new PCB is working by turning off your computer and connecting only the power line to the drive. When you press the power button to turn the computer back on, the drive should spin. If it appears to be spinning properly, turn the computer off again and connect the hard drive as it would normally be configured to recover your data.
6. Cut the power and disconnect the drive if the hard drive fails to spin or makes any unusual noises when powered on. Ensure that you connected the PCB properly and that it is mounted securely. If you have performed these steps as stated and the hard drive still fails to spin, the problem is likely mechanical and will require professional data recovery.
