Re: Bad Sectors on SSD?

But can not, then, say anything sensible at this point. Might be cause for a forum-wide poll/call for experience with a non-zeroing secure erase. And/or: can you hook up the old SSD as an extra and run the ADATA tool from the Windows 7 partition on the new one against the old SSD? It mentioned to a...

Re: Bad Sectors on SSD?

Have experienced nor ever heard of anything of the kind with the secure erase, on SSD nor HDD, SATA nor PATA -- and am unfortunately also coming up blank trying to think of any possible reason. The "5 seconds" is not unheard of; my Samsung 850 EVO 250G does about the same and certainly the hdparm -...

Re: Bad Sectors on SSD?

Mentioned "firmware-level reformatting" -- which I would do -- would of course necessitate you reinstalling the system on the SSD. You'd boot into a Live system from USB or DVD and run sudo hdparm --security-set-pass password /dev/sdz sudo hdparm --security-erase password /dev/sdz in which of cours...

Re: Bad Sectors on SSD?

Unfortunately I have very little time so I hope someone else can step in if this becomes involved... but certainly one difference I see is that your swap partition used to be of the correct type 82 and is now of type 83. If the UUID for the swap partition DOES in fact match this shouldn't I believe...

Re: Bad Sectors on SSD?

As to your last point: I expect you wouldn't have issues with plain dd : you mentioned a badblocks run finding everything hunky-dory. But feel free to use ddrescue . Certainly it's useful on actually damaged disks. My new SDD arrived today, but I can't quite figure out how to clone the disk. My pro...

Re: Bad Sectors on SSD?

As to backing up: although it can be a bit of an investment, I'd advise a NAS. With a 2-bay one you have in the form of RAID0 versus RAID1 (or 5) the choice between two-disk capacity or one-disk capacity with automatic backup on the other. And yes, certainly those disks can give out as well -- but ...

Re: Bad Sectors on SSD?

Last night that HDD officially broke down: Mint refused to boot, giving me drive-not-ready errors and such. It really paid off, that I set up my system to be able to run from SSD exactly for cases like that. So, all I had to do was comment out one line is fstab and everything works again - minus my ...

Re: Bad Sectors on SSD?

If as you say the drive is "full to the brim" this may be all the explanation you need for seriously degraded performance. Well, 1.2 TB of the drive are taken up by the win7 data partition alone, which isn't even mounted by default and should have no impact on performance. In any case I decided to ...

Re: Bad Sectors on SSD?

Can't for now say anything specific about general problems but note that your 2T drive will do just fine to store backups. Actually no, it won't - the 2T drive contains my /home filesystem and my win7 data partition ... it's always full to the brim, despite all my efforts to backup and move away da...

Re: Bad Sectors on SSD?

First off, thanks for the quick reply and the useful hints, it's appreciated. You have a lot of "Unknown_Attribute" SMART attributes so let's first of all update the smartctl database. You're running 6.5 so grab https://www.smartmontools.org/browser/b ... /drivedb.h and save it somewhere Hmm, that d...

Bad Sectors on SSD?

Hi, last summer I replaced my faulty 2TB system drive with a combo of a 250GB SSD (for the OS) and another 2TB HDD (for those large video files, games and stuff). Back then the drive started to behaved strangely, like video playback stuttering, checksums on single files failing and eventually refusi...

Re: SD Card Problem

Hmm ... from the dmesg and lsblk output I would guess that your computer doesn't recognize any partitions on that card. Can you read that card on another computer, maybe a windows machine? You could try to mount the block device manually without a partition: sudo mount /dev/sdc /mnt (this might need...

Re: SD Card Problem

Hi, I very much doubt, that forgetting to unmount your flash card would render it unreadable. Maybe the card reader or the card just isn't connected properly. Can you check if the operating system recognizes your card at all? Do the following: open a terminal and after you plugged in the card type d...

Re: How to mark bad blocks unusable?

jackcq, It is strange that you got different results from fsck and when running badblocls directly I'm befuddled myself and have no explanation for the disparity. Have you run smartctl on that device to see what it has to say as far as recorded errors and its overall health assessment :?: If you're...

Re: How to mark bad blocks unusable?

I never used badblocks directly so I was under the impression that it was badblocks that wrote to the bad block inode, but it's now apparent that it's fsck that does that :? Thank you, that seems to have worked. However, I am confused because the result seems different compared to running badblocks...

Re: How to mark bad blocks unusable?

2. Run fsdisk with the text file as input: sudo fsck -C -t ext4 -l ~/badblocks.txt /dev/sdd1 I would probably wait for a second opinion though before running this. I checked the fsck manpage, and while this looks correct I've never used fsck before and I might be wrong. Cheers! Fred This looks real...

Re: How to mark bad blocks unusable?

As far as I know the list displayed should have been written to the bad block inode so they will not be allocated to a file or directory. However you should double-check that with the dumpe2fs -b option. Thanks for the hint, but as I feared, badblocks only displays the bad blocks and does not actua...

How to mark bad blocks unusable?

I have this old faulty 2TB disk, which I want to use as a data dump. Yes, I know it has some bad blocks and I know, it can completely fail anytime. That's why I don't plan to write anything important to it, at least nothing I haven't backed up anywhere else. My question is how do I manage to blackli...

Re: hide user list in Mint 18.2/lightdm?

Well, yeah, that blog also says it's cross-distribution. And seems like Fedora also uses it (see https://apps.fedoraproject.org/koschei/package/slick-greeter?collection=f26). In the end it doesn't matter, if I'd have to to tweak the greeter or the lightdm config itself, I just remember that it used ...

Re: hide user list in Mint 18.2/lightdm?

I think the change you're referring to is mainly for the configuration tool. I've used lightdm on Fedora a few years ago (before I switched to Mint), it did not come with a configuration manager, but even back then it was possible to remove that user list by changing the configuration files directly...
