External HDD - Seagate backup plus, no partition info.
Posted: 07 May 2017, 12:37
Hi all, I've tried quite a few Testdisk guides/other forum posts, but at this point I'm out of ideas, I suspect the disk is probably too far gone, but I thought I'd ask in case anyone has any further advice/steps to try.
Background: A friend has a 1TB Seagate backup plus that had stopped working and just made a beeping noise on powerup. I worked out it was likely a stuck head on the platter and with some careful encouragement got it off the platter and the disk spinning again. I didn't expect it to be recoverable, but at this point I was slightly shocked it was spinning so I just plugged the SATA cable from an external caddy straight into the powered up disk. I was actually able to read the entire structure, and very slowly copy off a lot of the files.
This was with disk connected via USB, attached to an external caddy.
At some point windows reported a cyclic redundancy check and the drive stopped reading. At this point I turned to TestDisk; the drive no longer shows up in Windows (although occasionally it will), although it can be seen by TestDisk/Photorec. I can't currenly attach/scan the disk with CrystalDisk.
With the disk in the caddy, the USB connection will be lost from time to time while attempting to run chkdsk/TestDisk, so I've now connected it straight to the motherboard with a SATA cable.
Partition search fails to find any partion, as does the deeper search; it creates a very large (~2GB) log file, with most of the lines reading "Readfile The specified network resource or device is no longer available):

file_pread(7,3,buffer,48(0/0/49)) ReadFile The specified network resource or device is no longer available.
etc...
Is the disk too far damaged to be read at this point? I was initially surprised to have recovered/be able to read so much data, so I assume it's still roughly in tact on the disk, although connectivity seems to be the current issue.
Any advice greatly appreciated.
