hi ..... i have posted a new post regarding this issue as it has progressed a bit.
see my original post a few days ago - http://forums.buffalotech.com/t5/Storage/Buffalo-Drive-Station-Issue-lights-on-but-nobody-is-home/m-p/110078#M52346
I started off being unable to access the drive, which i believed was either the controller or the hdd drive itself .... i purchased a new external case and opened the case and connected the seagate barracuda which was inside the buffalo case to the sata connectors on the controller for this.
Now although it still remains sporadic I am able to access the drive, sometimes it locks up ... but i can currently access the drive and in my computer it shows the correct amount of space used in my computer, but the folders show as empty in properties and in the folders itself.
chkdsk wont work as it says the disk is RAW although in computer management it shows as healthy active primary partition, test disk keeps coming up with read error, whilst it is checking the disk
the only available option seems to be to format the drive, do you think if i did this, i would be able to recover the data afterwards????
if anyone has any suggestions i would be very interested in hearing them
thanks
