External HDDs are not recognized

Hi Geeks!

i have a big problem...

i have several external sata HDDs, which have all decided to become invisible and are not showing in 'my computer' they are in the disk management window but are described as 'unallocated' and not initialized.

this is what my toshiba satellite running win7 home reports!

when i try them in my older satellite (win xp) they report they are RAW format?

i have 2 types of external caddies 1 is esata and usb2 the other is usb2 and 3

they were working fine till i tried to access them via the usb3 connection which i bought as a pcmi (?) card for the later model satellite.

there is valuable data on these disks which i have stored on them....

any suggestion please!

Julie :cry

 

Forgive me for suggesting the obvious, but some times the obvious is overlooked. Try unplugging the external drive, then update your computer's drivers by going here: http://www.majorgeeks.com/Driver_Collector_d3982.html and try installing the drive after that.

 

Thanks for the suggestion... i will try later, still can't understand why when its on both pcs running different os.

i have another external drive that works fine?


a friend suggested check the boot space on the disks or the partitions?????
