Carlitos i had "the not recognized problem" in my perc5 controller and i downgraded back to the original dell firmware for my perc5 and the device got recognized without any problem in win 2008 r2.

ps: I had previously updated the firmware to the latest LSI version. Worked perfectly in openfiler and vmware esxi but not in windows 2008

thank you.

I did downgrade the firmware to 2 updates ago and it worked.

the evga x58 sli still does NOT recognize it (yellow exclamation w/ code 10), but it WILL let me enter the perc 5i bios by pressing ctrl r!

the GIGABYTE GA-EP45-UD3L DOES recognize the card and installes the drivers but, I will NOT let me enter the perc 5i bios by pressing ctrl r

so to set up the raid i have to connect everything to the x58 mobo, enter the perc 5i bios, and set up the raid. Then I have to move everything to the GA-EP45-UD3L so that I can see the raid i created.

What a pain in the A$$!

Do you want to install system on PERC 5i?

Todays Bench with a 256 MB stick, the original that perc had, and with disck cache enabled seems to be no more slowdowns, i got a constant transfer from another drive connected to the motherboard of 114Mb/s...

For now i think the problem could be in the 512 MB stick from samsung ...
Gonna keep testing.

The cable is from a local retailer and are like those red ones from ebay...
The Samsung drives are brand new ... i tested them and all seemed to be ok ...

Thank you for your help
Hi UnknownDevice,

I'm not sure if you finally figured out what was causing your slowness but after trying to give you a hand with your array, my array pretty much did the same thing as yours.

i think i found the problem with my array by unplugging one of the drives in my array so it would be in a degraded state and then re benchmarking the array. It turns out one of my drives was causing the problem because i got better benchmark result when it was degraded.

just remember to power off and unplug one drive at a time and once you have eliminated that drive (i.e benchmark results are the same) power off and plug that drive back in and then unplug the next drive and so on until all your drives are tested.

optimal array with all 4 Samsung drives


Degraded array with only 3 Samsung drives


BTW all drives passed ESTool diagnostics and all drives individually benchmarked fine.

I need to install the perc 5i w/ 2 x samsung f4 in raid 5 on my server computer. (mobo is GIGABYTE GA-EP45-UD3L). For some reason with this motherboard I can not enter t Ctrl R so i can configure there raid 5 w/ the perc 5i. The GIGABYTE GA-EP45-UD3L does recognize the perc 5i with both win 7 x64 and server 2008 r2.

Since I can't configure the raid on the GIGABYTE GA-EP45-UD3L, I moved over to my evga x58 sli motherboard running windows 7 x64. I CAN enter the perc 5i bios but, the perc 5i is NOT recognized. So basically I can't see the raid 5.

So I basically configured the raid 5 on the x58 board and then put the perc 5i back in the GIGABYTE GA-EP45-UD3L and now i see my raid 5 setup.

One lets me enter bios only, and the other lets me see the perc 5i/see my raid 5 only!

edit. Its 4 x samsung f4 not 2 x. sorry for the confusion.

@Carlitos714

Not sure if that is a typo, but you need 3 or more disks for a RAID5.

have you done the tape mod on your PERC?

yes did the tape mod. I finally got this thing to work!!!!!!!!!!!!!!!!

i have 4 x SAMSUNG EcoGreen F4 HD204UI. dont you have the same setup? I think there are actually you and another guy with the same setup right?

I will be adding another drive here in the next two weeks. I will add some bench marks on my current setup later today.

Yeah i have the same setup.

sorry you wrote in the post above

you only had 2 drives.

Before you setup your array can you make sure that you update the firmware on your Samsung drives. you need to make a bootable USB key or Floppy and make sure the drives are plugged in to the SATA ports on your motherboard, it will detect and update any samsung drives that are connected automaticlly so you can plug in all 4 at once if you want.

Hi A_Man_Eating_Duck, your right i should reply but work didnt allowed it

After your suggestion i hadnt time to continue testing, but your difference in results is pretty wired, what have you done to that drive if she passed the test ?

I´m going to have some WD20EARS to create another array to test and match the differences and then i can eliminate the Samsungs arrays and test them as you suggest.

Did you updated your firmware on the Samsungs with the one in the link ?

Thanks for your help, will update asap
