Se poate instala un HDD SATA 2 pe o placa de baza care suporta doar SATA 1 ?

SATA 1.5Gb/s and SATA 3Gb/sSATA is designed to be backwards and forwards compatible with future revisions of the SATA standard.

According to the hard drive manufacturer Maxtor, motherboard host controllers using the VIA and SIS chipsets VT8237, VT8237R, VT6420, VT6421L, SIS760, SIS964 found on the ECS 755-A2 which was manufactured in 2003, do not support SATA 3Gb/s drives. To address interoperability problems, the largest hard drive manufacturer Seagate/Maxtor have added a user-accessible jumper-switch known as the Force 150, to switch between 150 MB/s and 300 MB/s operation.[2] Users with a SATA 1.5Gb/s motherboard with one of the listed chipsets should either buy an ordinary SATA 1.5Gb/s hard disk, buy a SATA 3Gb/s hard disk with the user-accessible jumper, or buy a PCI or PCI-X Sata Adapter.

Asadar adica daca ai o placa de baza care are SATA 1 si este facuta cu chipseturile de mai sus: VT8237, VT8237R, VT6420, VT6421L, SIS760, SIS964 … nu merge sa pui un harddisk SATA 2 decat daca HDD-ul are jumper manual pentr SATA 1 … Daca chipsetul este diferit de cele de sus atunci e OK, se poate Instala un HardDisk SATA 2 pe o placa de baza care suporta doar SATA 1 si va functiona ca si SATA 1!!!

Btw:
- SATA 1 = SATA 1.5Gb/s

- SATA 2 = SATA 3Gb/s
