FileForums - Help! Not reading HDD

I have got 200GB Maxtor HDD in my PS2 and run it with HDadvance (PAL) ver 1

It was working fine just the other day but now after installing two more games via PC the PS2 cant see it, I have tired removing those two games but still no luck. I have checked all the connections and then seem to be good, HDadvance is loading to the boot screen and I can see the drive on a PC using winhiip 1.6.5 (48 bit LBA patch on)

It works fine with my 120GB Maxtor, I was told that even though I have version 1 of HDA by using the 48 bit LBA patch in winhiip I can using above 120GB even upto 2TB!!

Any ideas what might be wrong?
