Access my data on the disks after QNAP Firmware recovery?

[Birlago]

I have a QNAP TS219P+
version: 4.0.1.20130604 (after rcovery)
it crashed on firmware update , qnap finder could not see it anymore
i made the firware recovery removing both drives before doing it , using this link
https://wiki.qnap.com/wiki/Firmware_Recovery
it worked -Yeah!

Now:
qnap finder find it and tell me hard disk missing and it i put one in it will wipe all my data. so im scared to put back my disk and have all my data wiped
how shall i do to pass the initialisation and keep my data ?
(if i only put and wipe 1 drive will the second one be able to be restored after?)

Hard Drive Missing
Install and format at least one hard drive before using the NAS. A hard drive can be inserted to an empty disk bay without turning off the NAS. For the hard disk compatibility list, please visit http://www.qnap.com/go/compatibility_hdd35.html
Note: All the drive data will be cleared upon hard drive initialization.
Please make sure the hard drive(s) are installed correctly and the hard drive cable(s) are securely connected.


thanks for your help

read externally as explained a couple of days ago...

start doing external backups or you WILL loose all your files !

Thanks for your quick answer.
i start to understand that NAS are not secure (Raid was why i bought it in the first place , i was not counting on NAS firmware update failure - i was expecting QNAP to be able to read back the disck after firwqre recovery - i guess it is not a feature)

i tried to use your software but none of the disk is showing up ( i right click + "run it as administrator" as it ask)
(the disks on the HDD are G: I: J: )

do you know what i should do?

[dolbyman]

Has nothing to do with QNAP ..RAID is NEVER a backup

if that software does not work, use a linux distribution of your choice

[Birlago]

For the people that maybe still in my case :

i understood ( probably basic for most of you)
NAS is linux based file system EXT that cannot be read directly by windows so we need software to do so : here below 3 methods

- including Ext2explore mentionned by dolbyman , which does not work for me | but thansk to him to point me in the right direction! and i will try to learn what are and how to do backups :p
https://sourceforge.net/projects/ext2read/

- and Ext2 File which works for me , i can see them in windows and copy the data to another drive
link to ext2 File https://sourceforge.net/projects/ext2fsd/

Good luck to all of you

used raid5 qnap for many years, it worked fine. though when a drive is reported failing, i replace and it resyncs raid, and everything fine.

but regardless, still kept a backup just in case

if you don't have backups, then the fault lies on u :/ highly recommend u have a backup strategy

For the people that maybe still in my case :

doesn't matter their situation, it doesn't change the fact, you must have backups especially is the data is important to you. there is no other answer than this, other than expensive data recovery (if at all possible) or whatever mcgyver hail mary recovery u can find, but why go through that headache just get a proper backup plan.

i start to understand that NAS are not secure

the thing about this is, as long as you don't expose your nas online, don't upnp router/nas, and you regularly update, and you don't download malware to your network/devices, then you'll be fine. people that don't do their due diligence and the the opposite, those r the people that get hit then complain why they got hit also good idea to have backups.

if remote access is a requirement, usually vpn server on router is the way to do that. and also requires further diligence to maintain a clean/secure network. people who aren't up to the task are better of not doing that if they plan to stay safe

It is not only the EXT filesystem, but if you used a raid (i.e. raid0) reading data from a disk is not possible.
With disks set as "single disk" or "raid1" you can be lucky and get data back. For raid0, raid5, raid6 and other raid levels you need to rebuild the raid.
Either by adding all disks to PC at same time or by imaging every disk each after each, which needs finally a large storage capacity to store the images.
For such an external raid rebuild a special software is needed, which is not for free (i.e. u f s e x p l o r e r). I do no not have any experirence by myself with this, just read some posts about it.
The the most important protection are backups, backups, backups and...
more backups!

In case of newer NAS models the raid recovery is not all, LVM settings must also recovered which makes it more complicated to regain the data.
Solution here is ...
backups as well!
