Top of page Surprise removal of hardware is a common end-user scenario that has always been a challenge for Windows. During the development and testing of Windows 95 and Windows 98, surprise removal of hardware was often found to result in system instability or even hardware damage. System instability was still seen in Windows test labs early in the Windows 2000 product cycle, although hardware damage resulting from surprise removal has become much less common in recent years because hardware vendors have taken steps to prevent this problem. Late in the Windows 2000 development process and in the current Windows XP development process, Windows testers are encountering only minimal problems associated with surprise removal. Microsoft has generally viewed surprise removal of hardware as an issue that can only be solved by hardware vendors. Therefore, Windows development has progressed under the assumption that hardware vendors would address this issue. As technologies like PC Card, CardBus, and docking increased in popularity, Microsoft encouraged system and device manufacturers (OEMs and IHVs) to include physical interlocks in slots and connectors to prevent surprise removal of these devices. However, the hardware community has consistently expressed concerns about this approach because of the additional cost of locking mechanisms.
Reviews: After-Market Floppy Disk Drives Reviews AfterMarket Floppy disk drives. Professional FD-1, GTS-100, GTS-100X. Installing the FD-1 is easy; just remember to turn off all hardware http://www.atarimagazines.com/startv4n1/floppy_drives.html
Extractions: START ASSOCIATE EDITOR If your ST has only one disk drive then you've experienced the frustration that comes with copying disk files- the constant disk swapping when you want to copy even one file can be maddening. A RAM disk can help streamline things, but that eats up the ST's memory, memory that's better used for other things. After a printer I have found that an external floppy disk drive is the most important peripheral to have. Two new 3 1/2-inch floppy drives have recently entered the ST market that will make accessing and copying disks easier at a price that is in line with typical ST hardware: the Professional FD-1 from PCM Industries and the GTS-100 from Future Systems. Both drives are double-sided/double-density and support up to one megabyte of storage. The Professional FD-1 The Professional FD-1, from PCM Industries, is a 720K drive that will read/write up to 83 tracks and is compatible with all STs and Megas. The FD-l's design is modest but attractive, and the drive itself is very, very quiet. The drive is housed in a compact metal case that measures 1 1/2 by 4 1/8 by 7 7/8 inches, and its extra-long cable lets you position it along either side of your ST PCM has capped its product with a one-year warranty.
Extractions: Linksys Network Storage Link for USB 2.0 Disk Drives pagina: Sneldelen door Johan Zwiekhorst Als je een grote externe USB-schijf hebt en in een netwerk zit, zou het wel handig zijn als je die schijf gemakkelijk kon delen met andere netwerkgebruikers. Linksys biedt met de NSLU2 een oplossing daarvoor. Beoordeling Een grote externe USB-schijf kun je natuurlijk delen in een netwerk door die aan een pc te koppelen en de inhoud van die schijf dan gewoon te delen over het netwerk. Dat betekent dan wel, dat die pc altijd moet aanstaan als iemand anders gebruik wil maken van de USB-schijf. Bovendien kan de netwerktoegang erg traag zijn, afhankelijk van wat er precies gebeurt op die pc. Probeer maar eens zonder storingen mp3's af te spelen, terwijl de pc-gebruiker een grafisch schietprogramma zoals Doom 3 aan het spelen is! Net zoals een breedbandrouter veel handiger is dan een pc met internetdeling, is ook een netwerkopslagsysteem veel handiger dan een pc met volume- en bestandendeling. Nu kun je natuurlijk wel kleine netwerkopslagsystemen of NAS'en (NAS = Network Attached Storage of netwerkopslagsysteem) kopen, maar waarom zou je dat doen als je zelf al externe USB-schijven hebt liggen?

Peripheral Components Introduction to the 82077, Floppy Disk Controller The evolution of floppy is marked in little over a decade by a significant increase in capacity accompanied by a noticeable decrease in the form factor from the early 8 inch floppy disks to the present day 3.5 inch floppy disks. This decade will also be remarkable as OEMs adopt "Super" dense floppies. The most commonly seen floppies today, are invariably one of the form factors - the 5.25" or the 3.5". Each form factor has several associated capacity ranges. The 5.25" floppies available are: 180 KB (single density), 360 KB (double density) and 1.2 MB (high density). The 3.5" floppies available are: 720 KB(double density) and 1.44 MB (high density). The emerging super dense floppies will evolve on the installed base of 3.5" floppies. The latest member of this set is the 2.88 MB (extra density) floppy, pioneered by Toshiba. The corner stone of market acceptance of newer drives is compatibility to the older family. The 2.88 MB (formatted) floppy drive allows the user to format, read and write to the lower density diskettes. As programs and data files get bigger, the demand for higher capacity floppies becomes obvious. There are several 3.5" higher density drives available from various vendors with capacities well into the 20MB range. NEC has introduced a 13 MB drive and companies such as Insite has introduced 20 MB drives. Both drives require servo-mechanisms to accurately position the head over the right track. NEC"s drive has the standard floppy drive interface whereas Insite"s interface is a SCSI based. The market for these floppy drives will remain a niche unless they receive more OEM support.

These components each have a special job and they all work together to make your computer operate. Some components are hidden inside the computer, where you can't see them. Others can be seen partly from the outside. Every computer needs a power supply , to take electricity from your house and convert it into a current that works for your computer. The electrical cord that comes out of your computer, comes out of the power supply. When it is plugged into the wall, electricity travels from the electrical wires in your house into the computer's power supply. When your computer is turned on, the power supply allows the converted electricity to travel to other components inside the computer. The motherboard gets its name because it is like a mother to all of the other circuit boards. Found at the bottom of a desktop case or the side of a tower case, the motherboard is the largest circuit board and has many smaller boards plugged into it. It holds all of the most important parts of the computer.

This behavior occurs because the USB external floppy disk drive or LS-120 drive that is attached to the computer does not support this feature ("soft eject"). To eject the disk, press the Eject button on the drive.
High Performance SCSI & RAID: What Is RAID ? This paper described various types of disk arrays, referred to by the acronym Additionally, this array of drives appears to the computer as a single http://www.staff.uni-mainz.de/neuffer/scsi/what_is_raid.html
Extractions: What does RAID stand for ? In 1987, Patterson, Gibson and Katz at the University of California Berkeley, published a paper entitled "A Case for Redundant Arrays of Inexpensive Disks (RAID)" . This paper described various types of disk arrays, referred to by the acronym RAID. The basic idea of RAID was to combine multiple small, inexpensive disk drives into an array of disk drives which yields performance exceeding that of a Single Large Expensive Drive (SLED). Additionally, this array of drives appears to the computer as a single logical storage unit or drive. The Mean Time Between Failure (MTBF) of the array will be equal to the MTBF of an individual drive, divided by the number of drives in the array. Because of this, the MTBF of an array of drives would be too low for many application requirements. However, disk arrays can be made fault-tolerant by redundantly storing information in various ways. Five types of array architectures, RAID-1 through RAID-5, were defined by the Berkeley paper, each providing disk fault-tolerance and each offering different trade-offs in features and performance. In addition to these five redundant array architectures, it has become popular to refer to a non-redundant array of disk drives as a RAID-0 array. Data Striping Fundamental to RAID is "striping", a method of concatenating multiple drives into one logical storage unit. Striping involves partitioning each drive's storage space into stripes which may be as small as one sector (512 bytes) or as large as several megabytes. These stripes are then interleaved round-robin, so that the combined space is composed alternately of stripes from each drive. In effect, the storage space of the drives is shuffled like a deck of cards. The type of application environment, I/O or data intensive, determines whether large or small stripes should be used.
