Aligning sectors for an SSD?
location: linuxquestions.com - date: August 3, 2010
I have an Acer tiny desktop using laptop components and I want to replace its small laptop hdd running Vista with a Kingston SSDNow V Series Boot Drive 30GB and install Ubuntu, since it will support TRIM. I am aware of the current issues on some new hard drives with 512 vs. 4k sector sizes and the necessity to align sectors for those drives. And I know I've seen some posts or discussion of aligning sectors for SSD's.
I'll be doing more searching for info on this, but my previous searches on the 4K sector alignment issue for the new WD hdd's on linux were confusing. Does anyone have definitive information on the necessity of aligning 4k sectors on current Linux kernels, or on whether aligning sectors is necessary for SSD's?
Sandisk SSD bad sectors. Which software to believe?
location: ubuntuforums.com - date: March 13, 2015
I would like to have your feedback about a SSD disk (model X300s). I bought a new laptop few days ago running w8 (sucks!) with this SSD. Anyway, I run an Ubuntu 14.04 x64 live cd checking if everything is fine.
Regarding the SSD, if I open the disks from the Ubuntu unity menu, it says that the disk is ok with 5 bad sectors (when I bought it they were 4). So, I investigated and the same number of bad sectors is shown by HDSentinel (from Windows). The expected life time is more than 1000 days.
I contacted then SanDisk company, to check its opinion. They made me install the SanDisk SSD dashboard software (http://kb.sandisk.com/app/answers/de...rt-information) and I sent the report to them. They replied that there are no bad sectors and that HD sentinel as well as Ubuntu are not reliable for their model. In addition, the dashboard report that the status is 100% health.
I also tried sudo badblocks /dev/* with Ubuntu, saying me that there is no problem.
So, I'm really
Installing Ubuntu 12.04 on SATA and SSD drives
location: linuxquestions.com - date: June 6, 2012
I am getting ready to move and upgrade some PCs from a proprietary OS to Ubuntu 12.04. With the older OS, I had to slipstream in the SATA drivers.
What happens with Ubuntu 12.04? Can I start with bare SATA or SSD drive and a 12.04 install CD-ROM and not have to worry about drivers for SATA and SSD drives? Anything else to worry about
My newer motherboards have 8 GB RAM. Understand that his requires 64-bit version of Ubuntu 12.04. Is this correct?
LXer: AHCI vs. IDE Modes With A SATA 3.0 SSD On Linux
location: linuxquestions.com - date: August 5, 2012
Published at LXer:
Days ago benchmarks were shared from OpenBenchmarking.org that compared AHCI and IDE modes under Linux when it came to the resulting disk performance. There was a fair amount of interest generated out of that so some AHCI vs. IDE mode comparisons from a Serial ATA 3.0 SSD on an Ubuntu Linux host were benchmarked at Phoronix.
Asus Eee PC 901 has 2 SSD drives w/ 2 Ubuntu overlapping installs
location: linuxquestions.com - date: October 30, 2011
I know how the subject looks but it's true: I had one version installed, which I did manually. Then I accidentally re-installed Ubuntu 10.10 but automatically. This has created some serious conflicts which slow down everything but specially my graphics.
I have 2 SSDs & they exist thus (according to Disk Utility):
/dev/sda1 Extended partition, 4G, Usage: Container for logical partitions, Partition type: extended, Flags: bootable (0x05);
/dev/sda5 Swapspace, 4gG, Usage: Swap Space, Partition type: Linux swap, Flags: none, (0x82)
GParted details this drive as 3.26GiB & a SwAP Partition w/in it of the same size, and 509.06MiB of unallocated space.
/dev/sdb1 15G, ext4, Usage: Filesystem, Partition type: Linux (0x83), Flag: none, Type: ext4 (version 1.0)
/dev/sdb2 Extended partition, 722MB, Usage: container for logical Partitions, Partition type Extended (0x05)

[SOLVED] cant mount or format ssd drive

I just got a Patriot PS-100 mlc ssd drive and I cant mount it or put a file system on it.
I've installed Gentoo on many normal hdds before and though it would be the same with the sdd.
cannot open /dev/sda2 device is busy.
Failed installation on SSD drive
location: ubuntuforums.com - date: July 18, 2011
I tried to install Ubuntu 10.04.2 on my new SSD drive. Installation processes up to 25% copying files and stops with Error 30: Read/Write error to hard disk. If I try to install Ubuntu 11.04 it even does not recognize new hard disk.
Motherboard: ASUS M4N68T-M.
Drive: OCZ Agility 2 60Gb.
Searching result: possibly it could be problem with AHCI driver. I did not find any option about it in my BIOS but technical documentation says that my motherboard support AHCI by default. During installation Ubuntu uses sata_nv driver. How could I process installation using AHCI driver?
Practically brand new hard drive (6 months), Linux says "Disk has many bad sectors"
location: linuxquestions.com - date: February 8, 2011
I get a desktop notification in Gnome telling me that my hard disk may be failing when I log in and that my disk has many bad sectors.
The disk is a 6 or 7 month old sata drive. The model is a Seagate ATA ST3300620AS.
I don't know if this has anything to do with it, but I copied a 10 or 11 year old hard disk (containing Windows 7) onto this new disk.
It is odd (and annoying) that a new drive will be spawning these errors. Could it be a glitch due to the copying of the old hard disk to the new disk?
The hard disk in question does not contain my Linux operating system. It contains Windows 7. I boot into Windows 7 on this "failing disk" just fine and use it for certain Windows only tasks like design work with Adobe Creative Suite CS4 Master Collection. I don't seem to have any problems with it when I'm inside Windows 7.
I don't recall chkdsk in Windows 7 showing any errors. I only see this error notification when I boot into Linux.

swap partition on SSD a bad idea?
location: ubuntuforums.com - date: March 7, 2012
I just upgraded to an SSD (obviously a HUGE speed increase) and now I'm tweaking it to make sure it stays fast.
I'm used to putting the swap partition on the same drive as the root partition. However I came across this:

I enabled TRIM on the ext4 root partition. There's no way to enable TRIM (the "discard" mount option) on the swap partition as swap partition types don't support it.
Should I move the swap partition off the SSD?
SWAP on SSD, not used, Delete it?
location: ubuntuforums.com - date: August 3, 2013
Today i was for the first time kinda stressing my PC. Was running two VMs and bunch of other stuff. So first time most of the RAM was used.
So i checked the system monitor to see how it performed. And noticed that SWAP isnt used at all. And yes i use SSD.
What i am wondering now. As far as i understand. SWAP is kind of not so desirable on an SSD right? Because of the potential wear.
Maybe this is why its not even used already by default?
Any way should i delete Swap then? Because its actually disabled somehow on SSDs? Or is it actually still used? And its still ok to use it?
Thanks in advance,
