Hello,
I’m face a problem with many of my old LTO Tapes that was backed up using lto 3 and lto6 drives. The magority was backed using a software called Archiware P5 and the rest using Ltfs format.
Most of the tapes suffer from unrecoverable read errors when trying to restore them after a while. I tried different drives to read the tapes but I reach the same result.
The only way I found to get the data on the tapes other than a data recovery company.
After many searches I’m trying to find a way to take an image of the tape as a raw image with skipping all the read errors to a hard disk or a device to duplicate the tape to another new one.
Is there any other way or better way I can restore data from these tapes without sending them to recovery service.
Best Regards
Hi all, need some advice:
My DS220j has failed and cannot boot (suspect hardware/Bay issue). It was running RAID1, and one of the drives should still contain valid data.
I’m planning to upgrade to a DS224+. What is the safest way to recover and transfer the data to the new NAS without risking initialization or data loss?
The old drive has not been initialized or modified.
Any advice would be appreciated. Thanks!
Hello everyone,
I would like to ask for your advice regarding a possible migration of a data server to TrueNAS. I am part of a research group focused on atmospheric and climate studies, and we currently have a couple of powerful servers (EPYC, 128 cores / 1 TB RAM each) with their own local SSD storage. In addition, we have a separate data server with larger capacity, which we use to share a large folder via NFS.
At the moment, this is the only intended use for the server. We do not run virtual machines or databases on this storage—only data files, which we occasionally process directly without copying them locally.
The server specifications are as follows:
Chassis: Gigabyte S452-Z30-00
RAM: 64 GB (8 × 8 GB ECC DDR4 3200 MHz)
RAID controller: LSI MegaRAID SAS-3 3108
Disks: 18 × 14 TB drives in RAID 6
Network: Dual 10 GbE with LACP
Two sata SSD’s for OS.
Since the disks were approaching 5 years of use, we decided to replace them with 26 TB drives, and we have purchased a total of 29 disks. The issue is that I had originally included 4 × 64 GB RAM modules (for a total of 256 GB), but the order has been delayed and now the price has increased to over €1000 per module (procurement in the Spanish public sector is not exactly straightforward).
As an HBA, I have an AOC-S3008L-L8E, which allows me to avoid using adapters since the SAS expander cables use the same SFF-8643 connectors.
My current plan is to create 3 RAIDZ2 vdevs with 9 disks each (27 disks total) and leave 2 disks as spares. The server is located in a data center with limited physical access, so having spares available is important (especially since hardware procurement at the university can be slow).
The main concern I have is the amount of RAM. I am aware that 64 GB is quite low for this kind of setup, but at the moment it does not seem feasible to obtain more. I could take RAM from the other servers (it is the same type), but that would leave them in asymmetric configurations and would involve mixing modules.
Would you recommend any changes to this setup?
Thank you very much.
I’m hoping someone with more technical knowledge can help with my issue. my Ugreen NAS got briefly unplugged during use. I have about 4.5 TB of data on one drive with a RAID 1 backup on the second drive.
When the NAS got turned back on, I got an alert that my storage pool is degraded even though both of my drives are fine. It is telling me to repair my storage pool via Hard Drive 1. However, when I tell my drive to begin the repair storage pool function, it attempts before saying my request has timed out and to try again.
Does anyone know how I get the “Repair Storage Pool” task to actually run? I’m a little freaked out, because I don’t want to lose all my data. Please respond if you know what’s up!
Look for an Android data recovery software that also has a photo repair option, or a dedicated image repair tool. Some of them use a reference image to rebuild corrupted ones.
Just don’t expect 100% recovery. But you might still save a good chunk of those photos.
That makes sense. I do see parts of the image in most of them, so maybe there’s hope.
Any specific type of tool I should look for?
If the photos show half gray or partially visible, there’s a decent chance repair might work. I’ve had some images come back usable that way.
If they were totally blank, then it’d be a different story
Exactly. Think of it like this:
– Recovery = getting files back
– Repair = fixing broken files
You’re already in the repair phase
Nah, once the files are already recovered, other recovery tools won’t magically improve them.
You’re past that stage. Now it’s more about fixing the corrupted files themselves.
This has now happened twice in short time. A HD fail and the Synology server enters a state of horriblis. GUI does not work, but I can SSH to it. Most commands does not work, ie. neither restarting nginx nor sudo reboot. But I can navigate the file system, get htop to run (hardly any processes are running).
A forced restart (button) is the only way I have got to work. I have users requiring the server to be online, so not too much time with experimenting and diagnosing.
Server is rs18016xs+ running 7.2.2. It is in a VMM cluster with two other similar servers. All VMs also crash when this happens with a storage failure error.
RAID is RAID-6 with 17 x 12TB harddrives. It has a assigned spare drive with “automatic rebuild” checked. Disks are WD SAS He drives in expansion module. Two Intel 1TB SSDs as cache.
The server recognizes that the drive is dead, but instead of blocking the dead drive and start automatic rebuild on the designated spare disk it just goes bonkers. Why is this? A failing drive in a RAID-6 should not make anything fail; just log, alert and automatic reallocate data to spare.
Which logs should I take a look at now in retrospect to get any clues to what is going on?
Got it. So recovery won’t improve anything now? I was thinking maybe try another recovery app.
At this point, running recovery again won’t help much. You already got what was left.
What you can try now is a photo repair tool. Those can sometimes rebuild the image if enough data is intact.
Not ideal, yeah. Once overwritten, that data is basically gone.
But since your photos are partially opening, it means some data is still there. That’s actually better than completely dead files.
OS: Windows 11
I wanted two hard drives to mirror each other., so RAID 1 seemed good.
I had some software that came with the external caddy I have for these hard drives, which made the RAID 1 array.
Everything seemed to work fine.
I just went to back some stuff up to it and it seemed very, VERY slow at writing to it.
I tried to “safely remove hardware” but it wasn’t having any of it, so I just powered off the external caddy.
After plugging it in again, Windows 11 now says “The disk structure is corrupted and unreadable”.
I have tried each disk individually but I get the same error.
Where do I go from here?
I am happy to get rid of the RAID as it seems more problems than it’s worth.
If I delete the RAID (using the software), will it also delete the data?
Looked in Disk Management and it shows as a RAW volume.
Doing a chkdsk on it now.
Hi everyone, I’m really stressed right now. I have an important MP4 video that got corrupted after my camera battery died mid-recording. It won’t play at all. Has anyone dealt with this before?
