SATA Unreadable!!!!!!!!!!!!

[Peter Langly]

Hi guys, I have a problem which I would like help on

Here is my machine's spec:

AMD Barton 2600+ CPU
Abit KV7 Motherboard (latest BIOS)
2x 512MB Pmi PC3200 400MHz ram
IBM 80GB IDE ATA-133 7200RPM HD (Has operating system)
Seagate Baracuda 120GB SATA 7200RPM HD (used for storage)
Asus Nvidia GeForce 4 Ti4600
Thermaltake GIANT III
Tagan 480W PSU
Coolermaster Aero 7+ heatsink/fan
Thermaltake Xaser III case
Sony CD-RW + DVD-R 52x32x52x16x
LG CD-R 52x

My master is an IBM 60GB 7200RPM IDE ATA 133 (ribbon cable) HD.


The slave is a Seagate Baracuda 120GB 7200RPM SATA HD.

The machine was working fine untill I overclocked the CPU. Everytime I overclocked it, the SATA will be unreadable but when I changed it back to default settings the SATA is readable again. I tried all different combonations for the SATA to be readable when overlcocked. After a few tries (15+) the SATA was unreadable even when the CPU was back to default mode :(

What has gone wrong and what do I do?

Thanls in advance :)

Lock your PCI/AGP to 66/33

[Peter Langly]

Sorry for the n00b question, but how do I do that?

[Peter Langly]

If I convert the dynamic drive to basic, will it solve the problem?

Also, if I format the drive, wil this solve the problem?

[I.M.O.G.]

Locking the PCI/AGP bus is something done through the bios on motherboards featuring the nforce2 chipset or newer chipsets that also feature locks (some nforce3 150's and the upcoming nforce3 250 GB). The chipset is essentially your northbridge and southbridge which basically control communication across the mobo and incorporate certain features.

If that motherboard has an nforce2 chipset then you have the option to lock the PCI/AGP bus at their rated speeds of 33mhz and 66mhz respectively. This means that changing the FSB will only affect the processor and RAM basically, instead of affecting all of your components like drives, vid card, sound card, and modems - all components are affected on a motherboard that doesn't have PCI/AGP locks.

If you look through your bios, you should be able to find an option for this - I can't tell you exactly because I've never worked on an nforce2 chipset... But almost everyone around here has so someone can tell you if you don't find it for yourself.

I forget exactly what the difference is between dynamic and basic, but I would appreciate if someone could remind me - I wouldn't mess with that for now as it won't have any effect on your problem AFAIK. Formatting will only fix things if the drive is corrupted but if there is data on it you'd like to save then you may be able to run system recovery on it and repair any errors.

witht the kv7 you have to use dividers, set the divider for the higest which will make your ratios good @ 200mhz. Its the 6/2/1 i think , its in the first menu in bios

Hi guys, thanks for the help, I will try out what you have said but I would like to say that the Abit KV7 does not have nforce 2 it is a KT600 board.

I would recommend using basic drives instead of dynamic anyways unless you are running a large raid configuration. Dynamic drives really don't benifit on a regular system. It also makes data recovery a real pain if you would ever have problems. I had it happen to me a while back while I was running dynamic drives. Needless to say I no longer use the dynamic drive configuration. You should be able to lock your agp on the same bios page where you changed your clock speeds.
