Hi Everyone, new to forum please let me know if I violate any rules with this post and Ill try to correct.

I have seagate NA882WB9 external harddrive

WHAT HAPPENED
Possibly:
Linux computer shut down without properly unmounting drive?
bad i/o?

CURRENT STATUS
I cant get my linux computer to see drive at all. After downloading SeaTools I was able to get a windows 10 PC to show the drive. It shows as having 44gb of space remaining. I can click into the drive and see my top level directories. However if I try to copy and paste or click into second level of directories the drive gets hung up.

Plugging in drive the blue light comes on. Every once and a while (usually when doing SeaTools scan) the blue light will blink (usually a good sign). That usually means that the drive is about to get discovered.

Add remove hardware (device manager) from control panel shows drive (seagate expansion) but without details like how much storage space.

Recently I have had trouble getting any computer to see the drive besides showing up in Device Manager and unmount.

WHAT I HAVE TRIED SO FAR
-Windows 10 drive properties, check disk
Says no reason to scan, drive operational. Scan anyway freezes.

-Update driver says firmware is up-to-date, provider windows. However its dated 2009?

-Chkdsk on CMD, windows 10 and windows 10 bios CMD (advanced restart - advanced options - CMD)
can see drive, chkdsk /f and chkdsk /r freeze or fail

-testdisk on windows 10
can see drive, scans but says unable to find partition
quick scan says 48 bad sectors (?)
unable to get to step to write to IMG or preview files

-SeaTools on windows 10
sometimes SeaTools cant find the drive. It takes a few scans, unmounting drive, different usb port, scan again, restart computer, before I can get SeaTools to see drive.

Fix All, Short and long scans fail pretty much immediately.

-SeaTools bootable
pretty much same results as SeaTools on windows 10
{cool, tiny core linux!]

WHAT STEP TO DO NEXT?

other details:
The drive has had alot of read/write, mainly with running a bitcoin full node (not for very long though, maybe a week total). Twice I have downloaded the whole blockchain, about 170gb.

The drive has always made, what Ive thought of as a bad sound, when disconnecting after unmounting, similar to the sound of hard-shutting down a computer by holding power button. Otherwise the drive sounds fine, I feel vibration of spinning, no clicking or anything.

thank you!

Hi there !!! Do you need to recover the data from the drive or do you want to re-use the drive only ?

Re-using the drive is a BAD idea ! You should replace the damaged drive by a new one.

If you only have the bitcoin node software installed + the full blockchain you can simply download that again.

By the way that reminds me that i do have to update mine as well ... It grew very fast in the last years ... I still remember when the full block chain would take just 10 or 15 GB .... At any rate unless you have a wallet key that you do need to recover if what you have on the drive is just the blockchain and the software to run the node you can simply re-download to a new working drive ...

If you do need to recover data on the seagate .... STOP all that you are doing and consider the use of a professional data recovery service.

If you want a do-it-yourself sollution (you can't pay a cent to a dr firm) you will need at least to check the drive model (inside the enclosure) DO NOT OPEN THE DRIVE ITSELF and you will need at least a TTL adaptor. The procedure assuming the drive is a F3 ARCH would be to patch sysfile 93 and clone the drive to a working one. Then extracting the data with something like R-Studio to another drive ....

Good luck.

Thanks for your response Spildit,

I have other data besides the bitcoin that id like to recover. I understamd that professional recovery it at very least $300+? Id like to recover the data but it isn't worth that much. Id risk losing it with a DIY solution rather than spend 300+, unless shopping around for DR will bring the price down substantially.

Anyway for me to discover if the harddrive is software problem vs hardware problem?

I will look into the DIY stuff you mentioned.

Well ... This might be a VERY BAD decision but it's your data after all .... and yes even if you were to have justa firmware problem the price wouldn't be "cheaper" than $300 ...

For DIY :

Open the CASE - NOT THE DRIVE - and post a full model of the drive inside the enclosure - there will be a label on the drive with it's full drive model - not enclosure model.

AGAN, DO NOT OPEN THE DRIVE ITSELF !!!!

Now get something like this :

Connect it to the drive like this :

http://www.hddoracle.com/viewtopic.php?f=6&t=193

When you do have the terminal software opened power up the drive and post the log that the drive does produce. DO NOT ISSUE ANY COMMAND ON TERMINAL. YOU WILL KILL THE DRIVE FOR GOOD ... AND DON'T USE THE POSTED SOLLUTION FOR 7200.11 DRIVES AS WELL ... JUST CHECK WHAT LOG THE DRIVE OUTPUTS AND POST IT HERE.

If the drive does have firmware issues you might be able to get your data for less than $300 ... I know "someone" that can help you out for way less than that. If your drive does have head(s) issues do expect to pay at least $600 for a recovery assuming there are no media damage, etc ...
