ssd alignment with Ranish PM

Post by bmaamba » Thu Jun 13, 2013 10:27 pm

Hello,
I have bought a Plextor ssd (m5s-120GB) and I need some help in partitioning it in Ranish Partition Manager for win xp sp3.
Found this thread- viewtopic.php?t=55530 ; wherein cmthompson says " ....a program on the Ultimate Boot CD, called Ranish that will create a partition on an arbitrary C/H/S boundary. The correct values to use are 0/16/17, which equals 512 KB....."

Then below CTT replies as "I think MS recommends a 2048-sector alignment (1 MB) and Windows Vista also aligns at 1 MB by default during installation (if you have an unpartitioned drive) so I would also go for this value "just in case" - a 1 MB aligned partition is also 512 KB aligned, but not the other way around; seems that the erase block size for most flash chips is 512KB."

Now my questions:

1. What are the C/H/S values for 1mb alignment (instead of 0/16/17) ?

2. This 0/16/17 is, I suppose, the 1st 3 numbers in RPM i.e. the start of a partition. What should the last 3 numbers in RPM i.e. end of the partition (rather, what should be the last 2 numbers, as the 4th number will depend on size of the partition?)?

3. Has my system (c) partition to be the 1st partition in RPM, compulsorily ( i prefer to have a small dos/fat16 24mb partition as 1st partition in RPM)?

4. After getting the partition offset number (of the partition) in xp, what is the number to divide it with ( so that result is a whole number), so that it confirms I have a 1mb aligned partition?

Thanks

Did some experimenting (savepart, latest mini partn. tool wizard 7.8, AS program).

Q1 & 2) 0/65/2.

here are my 1st 3 rows (had to use F4 also in RPM).

0 0 1 0 0 1 0
0 0 2 0 65 1 2047
0 65 2 892 254 63 7,.....

Checked with AS benchmark program.It shows green-ok. But it says BAD for pciide (have a 300 GB ide seagate disk and a samsung sata 40GB disk). While installing winxp sp3, only Plextor was connected to the MB(GA41m-es2l). Hover balloon shows intel 82801GB/GR/GH sata controller and 27C0. While installing xp (not on aligned partn.), bios option was on enhanced sata mode.
How do i solve this pciide problem?
Thanks
