    Bios Acer 5750G doens't recognize SSD in Optical bay caddy


    Hi, my first post here but I've been reading a lot on this forum and always found the solution to my problems. Except now, I can't find any post related to my problem:

    I've been improving my girlfriend's Acer Aspire 5750G (i7-2630QM - 8GB RAM (upgraded from 4GB) -NVIDIA GeForce GT540M - HD: WD6400BVPT @5400rpm) and I wanted to install a Kingston SV100S2/256G (version: SSDNow V100) with Win7 Home Premium on the SSD of course.
    Roadmap to my problem:


    The SSD doesn't fit in the normal HDD bay: There are 2 plastic pins above the SATA connector so the SSD doesn't fit in there (the SATA connector of a normal 2,5" HDD isn't covered by the casing like the SSD). I found someone on the webs who just broke these pins off but I don't want to lose the warranty on the laptop... yet.


    Solution 1: I bought an optical HDD Caddy for the SSD so I could reinstall Windows with the Acer erecovery program which gave me the next problem: The stupid program doesn't let me choose where to install Win7!


    Solution 2: I downloaded all drivers seperatly from the Acer site and installed a second Win7 (from a USB stick) on the SSD. Next problem: I tried to install the 100MB partition with the bootmgr on the SSD but that didn't work when I only booted from the SSD without the normal HDD in it. I realised then that the BIOS didn't recognize the SSD in the optical bay. The BIOS only 'sees' the WD HDD.


    Solution 3: I deleted the 100MB partition on the SSD, reinstalled Win7 on it and used EasyBCD 2.2 to only boot from the SSD. I wanted to delete the windows on the original HDD (C: drive) but I couldn't (tried with disk management, diskpart and Easus Partition Master). I ended up shrinking the Windows partition on the normal HDD (with Easus) and making a new partition for extra data. I could remove the asigned drive letter from the 100MB partition but not from the windows partition (= C: ). The windows partition on the SSD is asigned to drive letter A:.


    So far my system works... Until I tried the WEI just out of curiosity and it gave me an error that it couldn't find a place to store the results (My windows is in Dutch so I didn't translate the whole error message). I'm just wondering now if I have a stable system and if everything is going to keep on working properly.


    Is there anybody that can tell me if I made some serious errors? Is there something I should do or shouldn't have done?


    Thing I'd like to fix if possible:
    - Make the BIOS recognize my SSD.
    - Change the drive letter of the SSD to C: and remove the windows partition on the normal HDD.


    Overall I've been pretty disappointed with Acer: No place for an SSD upgrade in the normal HDD bay (this mobo should have 2 SATA III interfaces and none of them is used) and their software is not upgrade-friendly at all... .


    Anyway, tips & tricks are very welcome... .

    I also posted this message on the microsoft technet forum... This is what I found out in the meantime (some thing I repeated because the next text is a combination of 2 answers to 2 replies on the technet forum).

    I already updated the BIOS to the last version (1.20). In the 75750G's BIOS the AHCI controller is already enabled (only SATA-ports on this laptop, no IDE). In the BIOS menu the SSD doesn't show anywhere. It should be on the ATAPI CD-ROM but nothing to see there. If I change the boot priority to the ATAPI CD-ROM, it doesn't work (with or whitout the WD HDD in it). It didn't even work when the bootmanager was still on the SSD.

    I guess the only option I have is to wait until my warranty is over (october 2013) and then try the SSD in the normal HDD bay or hope that eventually Acer releases a BIOS update that will recognize the SSD.I asked Acer if they could help me with the BIOS problem so I'll see if they can help me out in any way... I'll let you know.

    I know the problem is not in Windows. It's just that I have a strange system built up now. I just wanted to be able to boot from the SSD without having the bootmanager on the normal HDD and change the SSD drive letter to C:\.

    I tried this now:
    A different SSD and a normal HDD in the optical bay caddy: nothing recognized in the BIOS. I also tried the optical bay caddy in my Sony Vaio and no HDD to see there either.

    So the only conclusion is that the BIOS isn't programmed to look for a HDD in the optical bay... too bad. I think I just have to wait until my warranty's expired so I can cut of the plastic pins to fit the SSD in the normal HDD bay.

    First of all, you will not void your warranty if you change HDD, RAM or Wifi card ( I have the same notebook ).

    Secondly, can you read/write on SSD from Windows, or it's not recognised at all?

    Thanks for the reply but you're questions were already answered in my problem description.

    Anyway, problem solved: I cut off the plastic pins (=probably voided my warranty) and put the SSD in the normal HDD bay. Result: BIOS recognised SSD, reinstalled Windows and a smooth system...
