1.Hard disk fit IBM T30
2.Hard disk fit all laptops

What is the difference between this two hard disks?
The first one hard disk fit IBM T30,that means this hard disk only can used on IBM T30 laptop.for those customer who do not have IBM T30 laptop,if you want to use this hard disk,you have to purchase one IBM T30.The version for this hard disk is DIS V57,SSS V32.
The second hard disk is fit all laptops.The advantage is it do not have much demand on laptop,only require your laptop support USB 2.0. But this one software installation need pay a little bit attention.the installation maunal you can download from our website. The version for this hard disk is DIS V55 SSS V32.
Compare this two version hard disk,the hard disk fit IBM T30 speed may more fast and stable.We suggest this one to those who have IBM T30.

Item specification:
On vehicle models from the E65 on, BMW is for the first time using fibre-optic cables as standard for communication between control units.
The optical buses are notable for their high data transmission rate and they are not susceptible to electromagnetic interference. The optical buses in question are the MOST bus, primarily used for in-car entertainment electronics, and the byteflight bus, which serves predominantly safety-critical functions.
OPPS has been designed for encoding, individualising and programming ( CIP) via the Software Service Station (SSS) and envisaged for use as part of the BMW diagnostic system (DIS) from DISPlus and Group Tester One (GT1). It is intended for testing and programming tasks from the E65 series, taking the place of the diagnostic head.

OPS is intended for rapid programming of control units.
When operated at the SSS, no diagnostic or technical measuring pro-cedures are possible, as no measuring technology is incorporated; in this instance, OPPS / OPS is used predominantly for programming control units (flashing). Communication with the vehicle can be performed both via the MOST and via the OBD interface. The OBD interface is required for the power supply to the OPPS / OPS and has communication properties via which the vehicle can be identified and the data to be programmed can be determined. From CIP version 7.0, it is possible to delete fault code memories via OPPS / OPS.
