I'm thinking about suggesting my boss to go for sata adapter and SSD, instead of buying new SCSI drives for SPARC.
out here, a brand new 70Gb SCSI drive is about 100euros, and 140Gb is 200eur! (for that price, one could probably buy the adapter.)
has anyone tried it?
how well do modern... (1 Reply)

Hello everybody,
I need to connect a laptop 2.5 SATA hard drive to a Desktop board (which uses 3.5' SATA hard drives). I've tried the connectors and they fit excellent in the 2.5 SATA connectors.
The problem is that the laptop hard drive uses 5v and the PC's power source sends 12v. So, my... (4 Replies)

I have an upgrade path in mind for a new computer that will be stocked with a 2TB SATA 300 hard disk. This is a choice based on information that SATA 300 is not necessarily faster than SATA 600. The upgrade path in a year time or so would then involve the purchase of an SSD that would contain the... (4 Replies)

SD(4) Linux Programmer's Manual SD(4)
NAME
sd - Driver for SCSI Disk Drives
SYNOPSIS
#include <linux/hdreg.h> /* for HDIO_GETGEO */ #include <linux/fs.h> /* for BLKGETSIZE and BLKRRPART */
CONFIG
The block device name has the following form: sdlp, where l is a letter denoting the physical drive, and p is a number denoting the parti-
tion on that physical drive. Often, the partition number, p, will be left off when the device corresponds to the whole drive.
SCSI disks have a major device number of 8, and a minor device number of the form (16 * drive_number) + partition_number, where drive_num-
ber is the number of the physical drive in order of detection, and partition_number is as follows:
partition 0 is the whole drive
partitions 1-4 are the DOS "primary" partitions
partitions 5-8 are the DOS "extended" (or "logical") partitions
For example, /dev/sda will have major 8, minor 0, and will refer to all of the first SCSI drive in the system; and /dev/sdb3 will have
major 8, minor 19, and will refer to the third DOS "primary" partition on the second SCSI drive in the system.
At this time, only block devices are provided. Raw devices have not yet been implemented.
DESCRIPTION
The following ioctls are provided:
HDIO_GETGEO
Returns the BIOS disk parameters in the following structure:
struct hd_geometry {
unsigned char heads;
unsigned char sectors;
unsigned short cylinders;
unsigned long start;
};
A pointer to this structure is passed as the ioctl(2) parameter.
The information returned in the parameter is the disk geometry of the drive as understood by DOS! This geometry is not the physical
geometry of the drive. It is used when constructing the drive's partition table, however, and is needed for convenient operation of
fdisk(1), efdisk(1), and lilo(1). If the geometry information is not available, zero will be returned for all of the parameters.
BLKGETSIZE
Returns the device size in sectors. The ioctl(2) parameter should be a pointer to a long.
BLKRRPART
Forces a re-read of the SCSI disk partition tables. No parameter is needed.
The scsi(4) ioctls are also supported. If the ioctl(2) parameter is required, and it is NULL, then ioctl() will return -EINVAL.
FILES
/dev/sd[a-h]: the whole device
/dev/sd[a-h][0-8]: individual block partitions
