Seagate external

Why does my seagate 3tb external not show up for a long while and then get message saying "you need to format the disk in drive F: before you can use it", and sometimes very rarely i can access the external and copy files at a very slow speed

The drive shows under disk drives but disk management does not load up.

Your Seagate 3 TB external drive is a GPT drive.

I shall straight away get into Data Recovery mode using Test Disk. You must have an empty formatted drive of adequate capacity connected to copy all data into it. If that drive does not have sufficient capacity then you have to select only the important files and copy those to it when we come to that ( and if we come to it . Yep, Data Recovery is a dirty job with results unpredictable,except in most simple cases.)

Read Part 1 and Part 2 of my guide here Regain a lost drive using Test Disk - An Illustrated Guide

Download TestDisk Windows version 6.14 TestDisk Download - CGSecurity , extract it to your C drive. Right click on testdisk.exe in Testdisk-6.14 folder and run as administrator.

Ready to go?

First screen - No Log [ENTER]

Second Screen: You must be seeing three drives. Your system drive , your faulty drive and your destination drive to copy from your faulty drive.
( As a matter of fact you can go upto this stage without a destination drive connected just to make sure that your faulty drive is visible to TestDisk. If it is visible then close TestDisk by clicking on X on top right corner, connect your destination drive and start TestDisk all over again.)

Select your faulty drive , Proceed [ENTER]

Third Screen :Here you will select [EFI GPT] [ENTER]

Fourth Screen: Analyse [ENTER]

Fifth Screen: 1. If TestDisk is able to find the valid Partition Table, the partition/s will be indicated followed by the message No partition is bootable.
2. If not, you will get only No parttion is bootable message.

In either case,[Quick Search] [ENTER]

Sixth Screen: If 1. above (partitions found), you will straight away get a screen saying Structure
OK ......blah, blah...

If 2. above(no partitions found) you will get a question "Should TestDisk search for partition
created by Vista or later? [Y/N] (answer yes if you are unsure) Press [Y]. If TestDisk finds
the partition/s, these will be indicated in the next screen saying Structure OK.... blah blah

When you come to this screen saying structure OK ..... blah blah, halt halt halt. if you read it carefully it says 'P- list files" and that is what you will do. It is capital P.So select the partition and press Shift+P and all the files will be listed.

Select the files you want to copy and copy it to the destination drive.

How to copy the files to your destination drive: My external hard drive suddenly became unllocated:

You can also try to use "Partition Copy" in Partition Wizard Home Edition Free download Magic Partition Manager Software, partition magic alternative, free partition magic, partition magic Windows 7 and server partition software - Partition Wizard Online

If your faulty drive is visible in Partition Wizard you can select the partition and use "Copy Partition" in it to copy to the destination drive. Ideally your destination drive should be the same Seagate, same model 3 TB drive or any drive greater than 3TB say 4 TB.

I dont know if my external is GPT

Is TestDisk Windows safe to use? Does it write over the data thats already on the external?

Reason im asking this is because for now whenever i have the little chances to save data from the external i can at the slowest of speeds. I hope testdisk does not prevent me from saving data after its finished.

I havn't tried the test disk yet but im trying to find a way to get access the external again .

Yesterday i was using EaseUS data recovery and i was about a day into the recovering process and my external just came alive and let me access it however it did not show in disk management. This is the strange behaviour of the external, the data is still definetly on there. Just difficult to access it.

Now im trying to get access to the drive again

I tried running the testdisk guide but this is what happened:

Fifth window (in testdisk guide): After analyse, it says "Partition: Read Error". and No partition is listed.

To answer your queries, TestDisk is safe to use and will not write anything to the drive as long as you do not give the [Write] command somewhere down the line. Some new users in their anxiety go overboard and that is why I took all the pains to delineate the step by step procedure telling you where to stop.

Anyway since TestDisk now gives a read error, we will put it into cold storage now and see what Partition Wizard says.. The one thing I want to make sure is that you selected [EFI GPT] and not Intel.( All drives over 2TB will have to be in GPT format.

Did you change the USB cable and see? A faulty cable can play tricks. Keep recovering whenever it shows up.

Now run Partition Wizard and post a screenshot of how your external looks like it. Run Partition Recovery Wizard, by clicking on it in the left Pane. Select the faulty drive and do a Quick Scan. If everything goes fine, after the Quick Scan you will get a screen showing the partition/s. Post a screenshot, If that happens double click on the partition/s shown as indicated in that Window. If it shows all your files then select those partition/s by putting tick marks in the box. Watch the preview map at the bottom. If right, it should turn from Unallocated to what it was before with the file system shown. At this stage post a screenshot of that for me to examine and instruct further.

I know your night is approching so do it in the next one or two hours and then you can retire. (Do not close Partition Wizard till you get further instructions.)

If quick scan takes a long time leave it running overnight and look into it in the morning.

OMG, I missed to see your post No.5 that followed #4 in quick succession..

See, you overshot and tried to write instead of Shift+P as instructed to copy files.Exactly what I did not want you to do.

My post #2:

"When you come to this screen saying structure OK ..... blah blah, halt halt halt. if you read it carefully it says 'P- list files" and that is what you will do. It is capital P.So select the partition and press Shift+P and all the files will be listed"

Anyway no harm done since it failed to write. Repeat Test Disk. Do it and if files are shown select and copy.

I think i must have followed the wrong steps maybe?

I followed the steps listed in Regain a lost drive using Test Disk - An Illustrated Guide. Where it said Select partition type, Intel Intel/PC partition thats what i selected. Now i realise im suppose to select [EFI GPT].

I dont think any harm is done like you mentioned.

So i tried following the right steps as you mentioned and i get to the 5th screen as you can see in the prtscn picture. I then hit enter to quick search so far its not doing nothing. I will keep you updated jumanji. Thak you for your time and patient for helping me.
