I don't think so. However this got me pretty paranoid. Ive systematically wiped the system partitions on all my phones, tablets, computers, routers etc. There are still a few computers left - the xpenology computer being one of them. As of now, what's the recommended version to go with? Google tells me that version 6.1 has an option of adding better data protection through the Btrfs type volume. Is this stable on XPenology? How about file compression? The server has a quad core CPU doing nothing most of the time, might as well utilize the processing power to save some space - unless it has some significant downfalls. Transfer speeds are not an issue, as I'm bottlenecked my network transfer rate. Also, is there an efficient way to wipe the system partitions on all drives? (this is a 16 drive array) At this point I'm not worried about the data. I'll probably have to start over to get the Btrfs feature anyway. Will the installer do this for me, or do I have to manually wipe everything from a Live CD before I proceed with the install? As for the original question: I think the main problem is that FTP file transfers are not checksum validated upon completion, combined with an unstable router. From what I've gathered, rsync verifies checksums on both ends, so I'll be using that from now on, and hopefully my file corruption problem will be solved.

1 - All drives are working 100% 2 - I will give this a try 3 - the files were already downloaded to an external system and showing corruption. I need to narrow this down to a storage problem or a file transfer problem. I will first try by adding an external usb drive, and see if those files gets corrupted, or if its only the files on the SHR array. The disks are configured as SHR with redundancy of 2 drives. This will take some time though. Just hours after posting this - my system got hacked. For now I have offlined everything. Have to focus on keeping the originals safe - even more now that my backup appears to be corrupted.

I'm on DSM 5.2. I have 16 drives set up, and I've been using the server as a backup server most of all. Yeah, I know it's an old version but at the point of the build I wanted the most stable version, and this is what I was recommended at that point. Last night I decided to use the server to transfer some rather large audio files to a friend by making him an account on the server and uploading the files. I uploaded the files using SFTP (in Filezilla) over my local network. No errors. He downloads the files, and every single file has been corrupted in the process. Still parts of the data is intact, but there are also sections of silence and sections of full scale white noise. First of all I just realized that I may not have a useable backup of any of my data at this point. This is bad. Second, I need to figure out if it's the file system or the file transfer protocol that is failing. Any ideas? The data stream goes through an Asus RT-AC66U (router) and an Asus RT-N66U set up as an access point for the server, located in the basement. What's really bothering me here is that I'm not getting any errors. Everything seems fine, except all files on the server is probably garbage. What would you do to fault find this? I'm tempted to just part out the whole thing and go for a cloud service - still that won't help if the problem happens as the files are transfered. I want to figure out what's going on here

I gave up and reverted to 5.2. Then I gave up on using IDE controllers, and got IDE to SATA converters for all my old drives. https://www.ebay.com/itm/3-5-HDD-IDE-to-Serial-ATA-SATA-Adapter-Parallel-To-Serial-Hard-Drive-Convertor/232195324527?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 They seem to work fine! Just as I got all my old drives up and running I realized I was out of power connections for my newer drives, so no I'm waiting for a few of these: https://www.ebay.com/itm/PC-ATX-4Pin-4P-IDE-Molex-to-4-SATA-Serial-ATA-Power-Supply-Cable-Cord-18AWG-Wire/272988657406?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2648 Hopefully in a week or two it will all be up and running. For my purpose, I don't think there are any advantages of using a newer version than 5.2, so I'll stick to what works for now.

I intend to use either DSM 5.2 or 6.0.2. I don't really need any new features, this server will mainly be used for keeping backups. For me, this is more about giving my old hardware a new lease of life than maximising performance. Power consumption is not an issue. I live in a cold climate and need heating most of the year anyway. Putting 10 older drives to use makes sense for my purpose, even though I'd never do this if I built a nas for a client. A larger number of drives also helps justify 2 redundant drives. I'm going to give 6.0.2 another try on fresh drives and a different psu/motherboard before I give up.

Hi again, thanks you your input Polanskiman. I did some more testing, and my SATA controllers are actually working. I have two silicon image SATA controllers, both supported by additional drivers included in the custom extra.izma, and they seem to work fine. The non-working IDE controllers are Marvell 88SE6102 (included in motherboard) and highpoint hpt372A (PCI). These are also supported by the custom extra.izma, but will cause the system to fail to boot, on 6.0.2. When I was using DSM 5.2 both these controllers would seem to work, but whatever configuration I made on them (RAID, single disk etc.) would get dropped whenever I reboot. If anyone can reccomend an IDE controller that is tested and fully working with any version of XPEnology, I'd be very grateful. I have quite a few medium and large capacity ATA drives with low hours. It'd be great to be able to put them to use. I'll leave the MAC adresses for now, as it doesn't seem to be related to the issues I'm having.

Now however, whenever I insert a PCI PATA or SATA card or enable the onboard PATA controller, it seems that the server gets stuck on boot, and I don't get ethernet. I think I'll give DSM 4.3 a try, guessing it might be more likely for older software to work with my old hardware.

sbv3000: Thanks for your help! I'm not sure if it was disabling the onboard NIC or moving to a different PCI express slot that made the difference, but at least now it works. I'm a bit confused though: the mac address in the grub.cfg is now incorrect, still things seem to work fine. What's the purpose of setting the mac address in this file? For now I'm just testing 6.0.2 to see if it solves my problem with IDE devices being dropped from all types of arrays on reboot. If this does not work, I guess the last thing to try is to roll back to DSM 4.x.x

Hi, I've been trying for a while now to get jun's loader 1.01 to work. The built in ethernet adapter (atheros) is not supported, so I bought an intel adapter that should work. I updated the mac adress and the vid/pid of the usb stick, but still can't find the server. I then purchased a realtek ethernet adapter, updated the files, still nothing. Bought another Intel (different model), and same thing. I then bought another pendrive, and updated vid and pid, still same thing. Is there any way to troubleshoot this? I'm getting tired of buying new hardware that leads me nowhere :/ Btw: on DSM 5.2 all four adapters work fine, but I'm having issues with my ATA drives. Partitions are lost on all ATA controllers whenever I reboot (SATA works). Which is why I want to try 6.x.x

I tried reinstalling the SIL 3114 SATA controller, and attaching a drive, and it works fine. Array is not lost on reboot. Maybe a stupid question but: Perhaps IDE support is broken? Has anyone here got it working properly?

winscp is much better than the telnet client, thanks for the advise! I tried making single volumes on the IDE drives, and they're still dropped at boot. I tried pulling both PCI cards, re-enabling the onboard IDE, create two single volumes. Those are also lost if I reboot. It seems the main problem may be that the PATA modules are not loaded yet at the point when it starts assembling the raid arrays. I've been loading the modules using a script called S05disks.sh in /usr/syno/etc/rc.d I'll try renaming to S00disks.sh now assuming that the scripts are loaded alphabetically, and we'll see if that helps. There's also a feature in the bios to disable moving PCI adresses above the RAM. I'll try that as well. How do I mask out the IDE drives? Is it in the same file that I enabled support for more than 12 drives?

well it's a 750W PSU, currently running 8 drives (6 SATA and 2 IDE as shr2), a low power consumption GPU and a mid range (in terms of power consumption) CPU. It should be enough. I guess I should get hold of an oscilloscope to check for ripple, but I find it strange that it only happens on IDE devices. There's still a few things left to try, but it would be great if there was some way to make the system log what happens, since dmesg only shows the last 3 pages or so... I guess I should try out the SIL sata controller, as it's also on the PCI bus. That would determine if this is a IDE issue or a PCI issue. I was not aware of cable select being a liability, trying with Master&slave now

So I deleted the array, made a new one, then let the system reboot. My IDE drives are still being dropped from the array.

I entered the BIOS and disabled everything I'm not using, and it did not help. I then tried googling the error message, and realized I was having an IRQ conflict. I then enabled PNP OS in the BIOS, and the error is now gone. Apparently Linux will try to allocate IRQs regardless of this setting, so you have to make the BIOS stop assigning IRQs, or you'll end up with IRQ conflicts. I believe the problem is solved, but I have not yet had time to do any testing. On to that now Thanks for your help, I was about to give up on using the PATA drives. EDIT: yes you're right about my setup, it is currently limited to 16 drives, and I've edited the config file to allow for up to 20 drives. I intend to start with 12 drives or so, and keep the SIL controller free so that I can migrate to SATA disks as the old PATA drives die. At the point when I have 2 PATA drives left, I'll replace the 4port PATA controller with another SATA controller.
