I've installed 40 GB A-data S599 SATA SSD in Multibay but it's being shown as 9 GB and works only in MultiWord DMA 2 mode (about 30 MB/s).

How to correct this ?

I'm using Samsung HM160HC 160 GB PATA in HDD bay, and standard COMBO in DVD bay.

What does it say in Disk Management? The disk might be partitioned. –  imtheman Aug 16 '12 at 17:40
    
No. It says the same. Disk is 9 GB. –  Spacedust Aug 16 '12 at 18:07
    
Could you put up a screenshot of Disk Management? –  imtheman Aug 16 '12 at 18:13
    
This is not related to Disk Management. It's has something to do with SATA caddy. –  Spacedust Aug 16 '12 at 18:15

I've changed speed UDMA6 with hdparm for Windows:

hdparm -X udma6 /dev/sda

Now instead of 31/24 MB/s I'm getting 98/24 MB/s !!!

Now I need to figure out how to speedup write speeds with BAR-edit. –  Spacedust Aug 17 '12 at 11:10

It was disk issue only in this notebook. Installed Kingston V200 128 GB capacity is fine. Then installed A-Data S396 30 GB also fine.

Yes some SSD's have issues in notebooks because of mobile chipsets. –  ppumkin Aug 17 '12 at 10:23
    
I'm using 30 GB as a system disk and 160 GB as a storage disk. All is flying now ;) –  Spacedust Aug 20 '12 at 16:30
