Hi guys I need some help upgrading my thinkpad's hdd I'm confused Lenovo state that my thinkpad r52 type 1847 is sata and i've looked around my device manager and no sata controllers just a good old ultra ata one. The chipset in the laptop is a Intel 915GM with ATI Radeon x300 64mb dedicated graphics, I pulled my hdd out to have a look and the hdd is suppose to be a 5400rpm 40gb it's not it's actually 4500rpm also atop of the hdd it says it's ATA. As you can see i'm very confused by this situation can I use a sata hdd or does it need to be ata another thing I've heard it needs to be a hitachi travelstar used in IBM thinkpads with IBM/Lenovo firmware for the hdd to work is this true? so for example I couldn't put a 160gb 7200rpm 2.5' sata hdd in or even a 160gb 5400rpm hdd in from seagate for example. My Systems: iDEQ 200T, P4 3.4Ghz,1GB DDR400 Dual Channel,160GB SATA,19'' W/S LCD Monitor, IBM Thinkpad R52 What a Machine IBM/Lenovo Rule, Acer Travelmate 2305LCI

Detailed specifications - ThinkPad R52 ... according to Lenovo site. Lenovo specification sheet made no mention of the HD being SATA. ZDNet review indicates you have IDE. i_XpUser

Yeah, I don't know where you're getting your info from, but from the links provided by XpUser: * ATA Bus Interface * 4200, 5400 or 7200 rpm depending on drive size * Storage controller type = IDE * Hard Drive 40 GB - 4200 rpm
