2. Traditional Internal Technologies
PATA (IDE/EIDE)
SATA
SCSI

3. PATA (IDE/EIDE) molex power connector 40 Pin Cable
Red wire is Pin 1
Pin 1 will be on side closest to power
Older motherboards had 2 controllers
Primary and Secondary
Each controller was capable of supporting two devices (Master and Slave)
The role (Master or Slave) was determined by jumper settings on the drive (Single, Master, Slave, or Cable Select)
Slow and inexpensive

4. PATA (cont)

5. SATA SATA power connector 1 device per controller
Replaces PATA on modern workstation
Fast and inexpensive

6. SATA (cont)

7. SCSI Variety of power and cable types Requires SCSI controller (HBA)
Original SCSI chain supported 8 devices
each device must be assigned a unique ID (0 – 7)
0 is the lowest priority
7 is the highest priority
HBA is assigned the highest priority (7)
Boot device is assigned lowest priority (0)
(cont)

8. SCSI (cont) Both ends of the SCSI chain must be terminated
Device ID conflicts and improper termination are the most common problems
Fast and expensive

10. Partitioning
Partitioning is the process of dividing a drive into one or more usable units
Each drive may contain up to 4 primary partitions: one of which can be an extended partition
Extended partitions cannot be used until logical drives are created within the extended partition

11. Formatting Before a partition can be used it must be formatted
Formatting is the process of installing a file system to a partition or logical drive
Formatting is destructive and renders any existing data unusable
(cont)

12. Formatting (cont) Windows supports 3 different file systems: FAT FAT32
NTFS
Support for all OS’s
No NT 4 or Windows 95 support (pre OSR2)
Supported by Windows NT, 2000, XP, Vista, Windows 7
2 GB Max
32 GB max on Win2K and XP
16 EiB max file size
No Security
Features include built in security, compression, encryption, and quotas

13. Notes
A Fat32 file system can be converted to NTFS using the convert command
This is 1 way and cannot be reversed
Head crash occurs when a system or drive is jolted or dropped and the read/write heads come into contact with the platter(s)
This can cause permanent damage to the drive
Use of some advanced disk management features (spanning, RAID) require the disks be change to dynamic disks
This will make the disks unusable to Windows 98
