I bought a new laptop last December, equipped with a 256 GB Crucial M4 SSD
I installed Linux Mint on it and it worked well, except for the "unpacking PACKAGE" during updates that were quite slow. That was not really such an issue and everything else was fine. About 6 month afters, now in June; I want to install Debian Wheezy on it, so I created a bootable USB stick and start the installation.
Everything seemed to go fine up until the "Installing the base system" part, when debian start to unpack every package. It has been 20 minutes in this step, and it's not blocked but it seems to go really slowly (> 20 seconds for unpacking bash, for exemple).
I have tested both AHCI and IDE mode. I am installing using LVM and ext4.
I have tested an
hdparm -Tt /dev/sda, and got performance expected for my drive
# hdparm -Tt /dev/sda
Timing cached reads: 15718 MB in 2.00 seconds = 7859.40 MB/sec
Timing buffered disk reads: 759 MB in 3.00 seconds = 253.12 MB/sec
I tried a
smartctl --all /dev/mydrive and didn't find a "reallocated" line
I tried the
dd command to create/copy/... a large temp file, I didn't write the number down but there were in range of what to expect.
It seems like a random write issue of something similar, but I don't know how to investigate further.
I would like to find a way to test if the drive is defective, or if I configured something wrong, I can't find much on the internet ...
Thanks for any help
