Be careful not to drop the drive. Store the ST7050P in its protective case whenever it is not in use. Mounting the ST7050P --------------------- The ST7050P is designed to support the PCMCIA Type III standard for direct mounting. You can mount and operate the ST7050P in any orientation. To mount the drive, simply insert it into a Type III PCMCIA slot. You may have to power down your computer before changing PC Cards. See your computer manual for details. Software Installation Procedures --------------------------------- Before you can use the ST7050P on most computers, you must install the SystemSoft PCMCIA drivers using the SystemSoft installation. Then you must partition and format the PC Card. Generic installation procedure ------------------------------- The following pages describe a general software installation procedure that you can use on most computers. 1. Examine your Config.sys file. a. At the C:\ prompt, type type Config.sys. This displays the contents of your Config.sys file on the screen. b. If your Config.sys file contains: - a line that begins with device=emm386.exe or device=qemm386.exe, or - lines used to run previously installed PCMCIA drivers, then continue to step 2 below. 2. Modify your Config.sys file (optional). a. Make a backup copy of your Config.sys file. At the C:\ prompt, type copy Config.sys config.old. b. If you are using a memory manager (such as EMM386), you may need to edit your Config.sys file to reserve memory space for the PCMCIA drivers at addresses D000 through DFFF. For example, if you have a line in your Config.sys file that reads device=emm386.exe, you must add the following text at the end of this line: noems x=d000-dfff. c. If your existing Config.sys file lists device drivers for a PCMCIA ATA card, you may have to remove the lines that refer to these drivers. See your computer manual or documentation for any previous PCMCIA drivers to determine which device drivers are loaded at startup. d. If you modified your Config.sys file, reboot your computer before running the SystemSoft installation program by pressing the CTRL, ALT and DELETE keys simultaneously. 3. Run the SystemSoft installation program. a. If you are running Microsoft Windows, you must exit Windows before running the installation program. b. Insert the SystemSoft installation diskette into your diskette drive. c. Type a:\install and press ENTER. If your diskette drive is drive B, type b:\install and press ENTER. d. At each stage of the installation, the program prompts you for input. Follow the instructions on each screen using the options listed below. Most of these options are preselected. - Select first-time installation. - Select standard (not custom) installation. - Select 1 or 2 PCMCIA sockets as appropriate. (See your computer manual.) - Select to have the software installed on drive C. - Select to have the software installed in a directory named \CARDSOFT. After you press ENTER to confirm the directory, the instal- lation program copies files from the diskette onto your internal hard drive. Then, it notifies you that it is about to modify your Config.sys file. When it modifies your Config.sys file, it adds PCMCIA drivers that are loaded into your computer each time you reboot. The installation program also makes a backup copy of your original Config.sys file. If you have an EMM386 memory manager, you will see a warning to exclude the D000 to DFFF memory addresses. This message appears even if you have already excluded these addresses during step 2 of the installation process. Press ENTER to continue the installation. Remove any PC Cards when requested to do so. Then, press ENTER. Eventually, you see the message Procedure is now complete. You are offered the choice of exiting to DOS or running Setup for Windows. Do not run Setup for Windows at this point in the installation. Instead, select Exit to DOS. At the end of the installation program, you see the prompt C:\CARDSOFT. NOTE. The installation program refers to several SystemSoft utility programs (CONFIG.EXE, CSALLOC and SETUP.EXE). For detailed descriptions of these programs, see the SystemSoft user documentation included with your ST7050P. e. After the installation program has finished, remove the instal- lation diskette from the drive. (The software does not prompt you to do this.) Then, reboot your computer by pressing the CTRL, ALT and DELETE keys simultaneously. f. After the computer has rebooted, insert the ST7050P into the PCMCIA slot. After you insert the ST7050P, you should hear two beeps (first low, then high) as the software recognizes and configures your PC Card. If you hear these two beeps, continue to instructions on partitioning and formatting the ST7050P. AST Bravo installation procedure ================================= 1. Check your system setup.

Seek times shown here do not include controller or host overhead. All measurements are taken at 5.0V at sea level and 25*C ambient temperature. Track-to-track seek time is an average of all possible single-track seeks in both directions. Average seek time is measured by executing seek commands between random target tracks. Full-stroke seek time is one-half the time required for the drive to seek from track 0 to the highest-numbered track and back to track zero. Track-to-track read (msec) write (msec) 6/7 Average read (msec) write (msec) 18/20 Full-stroke read (msec) write (msec)<28/<30 Average latency (msec) 8.46 Spinup times ------------ Power-on to Ready (sec) 5 (typical) Standby to Ready (sec) 2 (max) Power-management mode descriptions ---------------------------------- The ST7050P features four power-management modes: Active, Idle, Standby and Sleep. These modes are available to the drive in either PC Card ATA and in 68-pin ATA mode. Active mode ----------- In Active mode, the drive performs all normal disc activities, including reads, writes and seeks. Idle mode --------- In Idle mode, the spindle remains up to speed, but the heads are parked away from the data zones for maximum data safety. The buffer remains enabled, and the drive accepts all commands. From Idle mode, the drive enters Active mode whenever disc access is necessary. At power-on, the drive sets the idle timer to 5 seconds (the drive enters Idle mode after 5 seconds of inactivity). In some computers, you can manually set the idle timer using the system setup utility. Standby mode ------------ In Standby mode, the buffer remains enabled, the heads are parked and the spindle is at rest. The drive accepts all commands and returns to Active mode whenever disc access is necessary. The drive enters Standby mode when the host sends a Standby Immediate command. If the host system has set the standby timer, the drive can also enter Standby mode automatically after the drive has been in Idle mode for a specifiable length of time. The standby timer delay is system-dependent and is usually set using the system setup utility. Sleep mode ---------- In sleep mode, the drive heads are parked and the spindle is at rest. The drive enters Sleep mode when a Sleep Immediate command has been received from the host. The drive leaves Sleep mode when the host sends a Hard Reset or Soft Reset command. After the drive receives a soft reset, it exits Sleep mode with all current emulation and translation parameters intact. Idle and standby timers ----------------------- At power-on, the drive sets the default time delay for the idle timer to five seconds. In most systems, you can manually set this delay using the system setup utility. Each time the drive performs an Active function (read, write or seek), the idle timer is reinitialized and begins the countdown from the specified delay time to zero. If the idle timer reaches zero before any drive activity is required, the drive enters Idle mode. If the host has set the standby timer, the drive begins the standby timer countdown as soon as it enters Idle mode. If the host has not set the standby timer, the drive remains in Idle mode. If the standby timer reaches zero before any drive activity is required, the drive enters Standby mode. In both Idle and Standby modes, the drive accepts all commands and returns to Active mode when disc access is necessary. Power consumption ----------------- Typical power measurements are based on an average of drives tested under nominal conditions using 5.0V input voltage at 25*C ambient temperature at sea level. Active mode power is measured with two spindle rotations between each operation and the drive in default logical geometry. Seek power is measured during one-third-stroke buffered seeks. Read/write power is measured with the heads on track. Typical startup currents for the ST7050P are 0.45 amps (0.50 amps maximum). Transient state changes may cause current peaks above the maximum level. PC Card ATA/68-pin ATA interface -------------------------------- The ST7050P supports the industry-standard ATA specification task-file interface and the PC Card ATA interface specification (Version 2.1). Pin 9 is used to select either 68-pin ATA or PC Card ATA mode. If the OE- signal is low during power-on reset, then the ST7050P configures itself as a 68-pin ATA drive. If the OE- signal goes high within the first 100 msec after power-on, the ST7050P configures itself as a PC Card ATA drive. If the OE- signal ever goes high after the first 100 msec following power-on, the drive enters an undefined state. NOTE. To operate the drive only in 68-pin ATA mode, pin 9 of the host interface should be permanently connected to a DC ground. Features of the PC Card ATA interface -------------------------------------- For a detailed description of the PC Card ATA interface, see the PC Card ATA Specification, available from: PCMCIA 1030G East Duane Avenue Sunnyvale, CA 94086 Phone: (408) 720-0107. The ST7050P supports all standard PC Card ATA registers and bits except the audio, power-down, write protect, and battery voltage detection bits. The ST7050P does not currently support twin-card addressing. System compatibility -------------------- A large number of new PCMCIA host systems are currently entering the marketplace along with various implementations of the PC Card ATA interface. For a complete listing of systems that have been tested for compatibility with the ST7050P, contact Seagate technical support. Features of the 68-pin ATA interface ------------------------------------ In general, the 68-pin ATA interface for the ST7050P uses the same basic ATA signals as Seagate's 3.5-inch and 1.8-inch AT drives. These signals are simply mapped to different pins. A detailed description of Seagate's implementation of the ATA interface is presented in the Seagate ATA Interface Reference Manual. Elements of the ATA interface that are unique to the ST7050P are summarized in the following sections of this manual. In 68-pin ATA mode, the drive supports both 8-bit and 16-bit data transfer and has no DMA capability. All data transfers are completed through programmed I/O. The ST7050P does not currently support master-slave handshaking. Remote LED ---------- The drive indicates activity to the host through the DASP- line on the ATA interface. This line can be connected to a drive status indicator driving an LED. ATA bus signal levels --------------------- Signals sent by the drive have the following output characteristics at the drive connector: Logic Low 0 to 0.4V Logic High 2.5 to 5.25V Signals received by the drive must have the following input charac- teristics, measured at the drive connector: Logic Low 0 to 0.8V Logic High 2.0 to 5.25V System compatibility -------------------- The ST7050P and SystemSoft PCMCIA drivers have been tested with DOS and Microsoft Windows on many computers, including those listed on the enclosed system compatibility sheet. For compatibility with the ST7050P, your computer must meet the requirements listed below. If in doubt, look in your computer manual. Your computer must have: - One Type III PCMCIA slot (10.5 mm high), or Two Type II PCMCIA slots (each 5 mm high) configured to accept a Type III PC Card. Your PCMCIA slot must be designed for a 5-volt PCMCIA device. Your computer must support a PC Card with a peak starting current of at least 0.5 amps. Your computer must support Version 2.0 or later of the PC Card Standard specification. NOTE. The ST7050P is a dual-interface card and can be used with a PC Card ATA interface or a 68-pin ATA interface. At startup the ST7050P automatically detects which interface is being used and configures itself appropriately. This User's Guide describes the installation and use of the ST7050P with a PC Card ATA interface only. Partitioning and formatting the ST7050P ---------------------------------------- CAUTION! Repartitioning or reformatting the ST7050P destroys all data on the disc. Make sure the you back up all data before repartitioning or reformatting the card. The ATAINIT pro-gram does not warn you if the PC Card has previously been partitioned or contains data. Partitioning the ST7050P ------------------------ 1. Insert the ST7050P into the PCMCIA slot. Listen for the two beeps that indicate the computer recognizes the card. 2. Determine which drive letter has been assigned to the ST7050P (usually drive D). If in doubt, type: c:\card-soft\ cardinfo and press ENTER. CAUTION! Make sure that you select the correct drive. You will destroy all data on the drive you select. 3. Type c:\cardsoft\atainit and press ENTER. Then, select the drive to partition. 4. The program should display the following drive parameters on the screen: Fixed Cylinders: 580 Heads: 9 Physical Sectors/Track: 16 If the parameters listed on your screen match those above, press ENTER to partition the disc. If the numbers do not match, restart your computer, insert the ST7050P, and run the ATAINIT program again. If given the option, do not select compact format. 5. Format the ST7050P immediately after you partition it. Formatting the ST7050P ----------------------- 1. Make sure the PC Card is inserted in the PCMCIA slot. 2. Determine which drive letter is used by the card (usually drive D). If in doubt, type: c:\cardsoft\cardinfo and press ENTER. 3. At the C:\ prompt, type format d: /u (assuming that the card is drive D). The FORMAT program then prompts you to enter a drive volume label. Type any name you want (up to 11 characters in length). 4. To make sure the PC Card is working and to see a display of available space on the card, type chkdsk d: and press ENTER. The output should show at least 40 Mbytes of free space. Inserting the ST7050P --------------------- Make sure that no other cards or protective devices are in the PCMCIA slot. Gently slide the ST7050P into the slot until it meets resistance. Then gently push on it to make sure the pins are fully engaged. The card should slide in easily. If you force the ST7050P into the slot, you may damage the pins. In some computers, you must insert the card upside down. If you are using the SystemSoft PCMCIA driver supplied with the ST7050P, your computer indicates that it recognizes a PC Card by emitting two beeps, the first beep lower than the second. If the computer recognizes but cannot configure the PC Card, it emits a single low beep. No beep indicates either that the PC Card has not been inserted completely or that it has not been recognized. When you insert the ST7050P into a slot, the drive motor takes about three to five seconds to come up to speed. If you try to access the PC Card while the motor is spinning up, you may see a message, General failure reading drive D. Abort? Retry? Fail?. If this occurs, simply wait a few seconds, then press R to retry. Hot Plugging ------------- Many computers allow you to insert or remove a PC Card while the computer is in normal operation (hot plugging). However, some computers must be turned off before you can remove or insert a PC Card, or rebooted after PC Cards are changed. CAUTION! If your computer does not support hot plugging, removing the PC Card while the computer is in operation may cause you to lose data. In addition, while in Standby or Sleep mode, your computer may not recognize that a PCMCIA card has been inserted or removed. Read your computer manual carefully to determine under what conditions you can insert or remove a PCMCIA device. Removing the ST7050P --------------------- Before removing the ST7050P, make sure all data has been saved. If your computer has an eject button or slide, gently push the button or slide. Then, slowly pull the card outward. Do not bump or drop the ST7050P as you are removing it from the slot. If you are using the SystemSoft PCMCIA driver, your computer should emit two beeps -the first beep higher than the second- when you remove the PC Card. If you have difficulty removing the PC Card, make sure that it is not locked in the slot. See your computer manual for details. CAUTION! The eject mechanism on some computers is strong enough that an ejected PC Card may slide completely out of its slot. This could damage the ST7050P if it falls out onto a hard surface. Before ejecting the ST7050P, always place your hand next to the slot to catch the card as it comes out. Saving safely -------------- Do not remove the ST7050P or turn the computer off while information is being transferred (for example, immediately after loading or saving a file). Wait a few seconds after saving your work to ensure that all disc operations have been completed. If you remove the ST7050P before all data has been saved, you will lose data. Some computers automatically stop disc activity when they enter Standby mode or Sleep mode or when their covers are closed. If your computer has this feature, be sure that all data has been saved before you close the cover. If your computer uses write caching, data that has apparently been saved may be transferred to the cache and stored there for a while before being transferred to the ST7050P. If you remove or power down the ST7050P before it has received this data from the cache, you will lose the data. For this reason, we recommend that you do not use write caching with the ST7050P. General information -------------------- After you partition and format your ST7050P, DOS or Windows can access the PC Card as drive D or E. If you remove the card and try to access information on it, you will see a Device not ready message.
