Windows 7: hdd crash need help to recover files

250 gb seagate with windows 7 pro. crashed and now it wont boot. hooked it up as slave and have tried several recovery programs, but no luck. says crc errors, or raw partition. I have it hooked up to a usb portal and would like any help to recover my files. I can feel the hdd spinning and no grinding noises. have tried Recuvra, easeus, Icare data recovery.

Now you have put that hard drive in an external casing and plugged it in into the USB port of another desktop/laptop. Am I reading correctly?

If your drive appears in the Disk Management, just take a screenshot and upload it.

it does appear in disk management, but it shows no size. cannot view properties....nothing

A picture can tell 100 stories which even a thousand words can't tell. Please upload the screenshot.

my usb reader not working now and when I connect hdd via sata cables, it is not recognized...does not show up in bios or anywhere else. drive is spinning

Sorry, but if the BIOS won't recognize the drive, there is probably nothing you can do. I've used RecoverMyFiles and GetDataBack to successfully recover files from failing hard drives -- but in all instances, the BIOS was able to recognize the drives.
