Windows 9x/ME adds the following properties:
Int13 Drive Number
128 for the first hard drive accessible through Int13, 129 for the second one, etc.
0...128 for drives and other devices accessible through a Windows 9x/ME protected
mode driver, if their Int13 device option is disabled. R-Studio can use Int13 disk
access, and for some drive types, like SCSI devices, Int13 access is preferable. You
may consider enabling the Int13 device option in the Windows Device Manager for
such devices.
Int13 Extension
Version
Int13 Extension Version Support for hard drives. Extended Int13 support is necessary
for large drives. If this property is zero, Extended Int13 is not supported, otherwise, it
shows Extended Int13 standard version, the large, the better.
3.Properties controlling access to hard drives and logical disks
This section shows properties that control access (read and write) to hard drives and logical disks. They are
set to their optimal values and should be altered only if access problems appear.
More information...
Drive Control
Maximum transfer
Maximum data size that can be read or written during a single access to the drive. If
there are problems with drive access, decrease the value of this property
I/O Unit
Data size read or written during a single access to the drive is a multiple value of this
property. If there are problems with drive access, decrease the value of this property
Buffer Alignment
Drive data transfer buffer is positioned at an address multiple value of this property. If
there are problems with drive access, increase the value of this property.
These three properties are set by OS drivers. If the drivers set incorrect values, problems may appear during
data transfer operations. You can alter them until data transfer becomes stable.
I/O Tries
Number of read/write tries during access to the drive. If there are bad sectors on the
drive, increase the value of this property. This may help to successfully read those
sectors. Sometimes, if the I/O Tries parameter is set too large and there are some
unreadable sectors on the hard drive, the hard drive-controller pair may refuse to
perform any successive read/write operations with the entire hard drive when it fails to
read/write such sectors. In this case, set this parameter to zero.
The default value is specified on the Settings (Bad Sectors) panel.
