Momentus XT, Momentus, Momentus Thin, MobileMax, and other notebook drives

[Vincent Dee]

After I found out my windows lagging and pausing due to momentum XT, I downgrade to conventional 7200RPM hdd. Now running smooth, though startup not that fast compare to Momentum XT but once loaded into windows, everything running fine.

Here it reboots but doesn't do anything, I just goes straight into windows again.

Model: ST95005620AS, Serial: [ Edited to comply with forum guidelines ], Firmware: SD26

Machine is a MacBook Pro 2011 17inch with bootcamp....in theory is not any different from any PC.

Use the CD ISO version. It's also safer than the Windows version.

I did, it works!  thanks!

toooooooo slooooooowwwwwwwwww compared with SD25. Is it possible to downgrade to SD25 ?

Use the bootable CD ISO version of the updater:

Then follow the procedure in this thread to forcibly downgrade your firmware:

That said, I'd run a HD Tune read benchmark against your drive. Look for large dips in the performance curve, and large amounts of scatter in the access time graph. These will correspond to "slow" sectors, ie those requiring several retries.

To Seagate,

Are you really sure SD28 is fit for use? I have no problem using firmware 23-25 and once I upgraded to SD28 my drive starting to slow down, auto-reboot during sleep and soon the drive corrupted and fail seatool basic test.

Are you really sure Seagate?

No change: Upgraded firmware to SD28 and the unit still fails to spin-down, instead exhibiting an audible "chirp" whenever the OS attempts to spin-down the drive, which is about every few minutes or so:

I have same trouble since SD28, slooooooooow boot now with W7 (25'' with SD25, 50'' with SD28)... and some strange sounds like "clic clic" sometimes...

This is a SHAME I never had this with SD25...

Any way to downgrade SAFELY to SD25 ? the iso process scare me...

f.... seagate people whats wrong with you ?

Anyone else having problem with the SD28 "damaging" in any way the drive ? I had SD24 and updated to SD28 and now I don't know if this was a good ideea... Maybe SD26 was better after all (using WinXP SP3 on a Toshiba laptop)

My SD28 (updated from SD24, factory default was SD23) flashed without any problems, with the ISO. I didn't need any Force Flash method... The SD28 behaves very well, until now I don't see any issues, no lags, no hiccups, no beeping/chirping. The drive parks the heads after 25 seconds of inactivity (measured myself). No spindowns, APM is set to 128 by default.

SD28 is about 2 times faster in terms of boot time than the Scorpio Black WD5000BEKT (1 min vs 2 minutes)
