You ask :
1. " I'd like to buy a hard disk to a Toshiba Satellite model A105-S4104. This laptop is SATA 1 compatible (1,5Gb/s). However I’d like to buy a SATA 2 (3Gb/s) HDD and use it on other future machine. I’ve done some research and I know this is possible with desktop machines and HDDs of 3.5”. This is, use a SATA 2 HDD on a SATA 1 compatible desktop. I’ve read this is possible by setting jumpers… Is it possible with laptops? In other words, can I buy a 2.5” SATA 2 HDD to this Toshiba Satellite A105-S4104, and will it work? Are there those jumpers in this kind of 2.5” HDDs?
Regarding the jumpers; the jumpers for the Momentus models you are interested in, can be set, just as in a 3.5" drive, to 1.5 or 3.0.

Desirable Seagate’s HDD models: Seagate Momentus 5400.5 (ST9320320AS) Seagate Momentus 5400.6 (ST9320325ASG ou ST9320325AS) Seagate Momentus 5400 FDE.3 (ST9320322AS) "
Laptop computers have 3 main issues to address:
1) Physical compatibility. Seagate laptop models come in 9.5 mm height, or approximately .374 of an inch. Verify what your computer can support and select a model that meets that maximum height requirement
2) Addressing capability; Most SATA laptop systems employ a 48-bit addressing system for data transfer between the operating system, BIOS, the system chip sets and the hard drive. 48-bit LBA addressing, increases the drive capacity limit to 144 petabytes. Hardware and software solutions are required from your O/S, BIOS and Chip Sets to enable the 48-bit address feature set. Some laptop BIOS are set with a manufacturers own limitations and contacting the manufacturer regarding maximum drive capacity is recommended.
3) System compatibility. Some laptop manufacturer's designs were somewhat proprietary and would only work on certain model disc drives. This means the manufacturer had designed a system that has requirements beyond the SATA ANSI standards as determined by the American National Standards Institute, (ANSI) committee. Again, contacting the manufacturer regarding maximum drive capacity is recommended.
We believe the drives you selected will present no physical problems but you will need to confirm that prior to making your purchase. You will need to contact Toshiba regarding capacity limits. Operation in 1.5 and 3.0 environments is no issue. We have included the specifications of the selected drives for your review.
