think I solved the problem (at least for my system):
with Hitachi Feature Tool v2.15 (actual version) changed on the HD's in
question the following settings:
- Max capable drive interface speed – changed from 3.0Gb/s to 1.5Gb/s
- Spread Spectrum Clocking – changed from nothing to Disable
My HD's are as follows:
HDD0: HITACHI HTS722010K9S (100GB) - the original one
HDD1: 2x Hitachi HTS545050B9A (500GB) and/or 1x Hitachi HTS54323232L98 (320GB)
System information:
Mainboard : LENOVO T60 200768U
Processor : Intel Core Duo T2500 @ 2000MHz
Memory : 2048MBDDR2-SDRAM
BIOS Version : 79ETE6WW (2.26 ) - the latest
ultrabay adapter: original Lenovo (but not 100% sure coz I bought it in China)
Symptoms before the change:
at least one time out of 4 cold-boots, I got the Initialization error on HDD1
for both the 500 and 320GB HD's but never with the original 100GB disk,
or with any of my old SATA 50 or 100GB (from my old T41p).
Details and tests:
- firstly I changed the settings on the one 500GB HD.
- after this change, i tried about 20 times to cold-reboot the ystem; no more
any hang or error-message -

- first time since i have this Thinkpad.
- then i inserted the 320GB HD in the bay - already at second cold-boot the
Thinkpad hanging on boot (as usual...)
- after changing the setiings, this disk also booted normally
NOTES:
- on the 100GB disk, the change-speed function is disabled in Feature Tools
- on ALL Hard Disks, the "Spread Spectrum Clocking" was not set.
- there is no difference between speed before and after (with HD Tune)
- I did not tested with other HD-brands. Don't have the means to do so.
CREDITS:
The idea came to me after reading the post from piit dated Nov 26, 2010. He
changed the drive interface speed by jumper - which I couldn't coz no such
jumpers on my HD's.
Thanks piit !!!
Hope this may help to someone...
Thanks!
